Guideline for Emergency Response Plan for the storage of Hazardous Substances

Guideline for Emergency Response Plan for the storage of Hazardous Substances

Hazardous chemicals have the potential to seriously endanger life and pollute the environment. Such chemicals have to be carefully managed at all time to prevent any accidental release. The successful implementation of a chemical safety programme requires co-operation from the industries to manage their hazardous chemicals properly and the support of the general public.

EMERGENCY RESPONSE PLAN

Notwithstanding the controls and precautions taken, one cannot rule out the possibility of spillages and accidental releases of hazardous substances during transportation. With well drawn up emergency plans and proper training, such releases can be effectively contained and the damage to the environment and dangers to the health and safety of public minimised.

As a condition for granting licences and transport approvals, companies are required to put up emergency response plans.

The plan must be comprehensive and should contain the following key elements :-

• notification procedures; (persons and authorities to contact and how to contact)
• emergency procedures to contain and decontaminate spills; (immediate actions to be taken by driver/ground staff and actions to be taken by the company upon being informed)
• emergency equipment to be carried on the vehicle and at base such as personal protection equipment, absorbents, neutralising solutions and salvage drums;
• Material Safety Data Sheets of the hazardous substances transported.

The emergency response plan (ERP) shall be vetted and approved by SCDF before a Transport Approval may be issued.

Under the provisions of The Environmental Protection and Management (Hazardous Substances) Regulations, in the event of a chemical fire / release, the licence holders\transport approval holders are required to:

• block off the area contaminated by the hazardous substance;
• notify SCDF and the PCD;
• take immediate action to have the area decontaminated and return the situation to normal.

EMERGENCY RESPONSE PLAN (ERP) FOR THE STORAGE/USE OF HAZARDOUS SUBSTANCES

The key elements of the ERP are briefly as follows: 

Introduction

 

1 Introduce the activities of your company and its need for the storage/use of hazardous substances.
2 Include maps/diagrams of the site and storage areas.
3 Include the inventory of hazardous substances stored as follows:

Name of Substance	UN Hazard Class	PSA Dangerous Goods Class	Unit Capacity of Container/Packaging	Max Qty Stored at Any One Time

ALL LORRY CRANE OPERATORS TO BE CERTIFIED BY SEPTEMBER 2013

ALL LORRY CRANE OPERATORS TO BE CERTIFIED BY SEPTEMBER 2013
New course launched by WSH Council to enhance safe operation of lorry cranes

By September 2013, all lorry crane operators will have to be certified under a new training course aimed at enhancing safe operation of cranes. This course is a new requirement under the Workplace Safety and Health (WSH) (Operation of Cranes) Regulations 20111. There are currently about 3,500 lorry cranes2 being operated island-wide and they may pose potential risks to workers and members of
the public as they operate on the roads even during peak periods for landscaping and other activities.

Lorry Crane Operator Course

The WSH Council, in consultation with the National Crane Safety Taskforce,  has developed a new course and test for lorry crane operators. The Lorry Crane  Operator Course (LCOC) is a 2½ day course designed to equip lorry crane operators  with the basic skills and competencies required for the safe operation of lorry cranes.


 Enhancements to the Regulations were previously announced by Mr Hawazi Daipi, Senior Parliamentary Secretary for Ministry of Education and Manpower at the 28th Annual Construction Safety, Health and Security Campaign, organised by Singapore Contractors Association Ltd on 19 July 2011. The Regulations that took effect in September 2011 will strengthen the safety of lifting operations by cranes by requiring the establishment and implementation of a comprehensive Lifting Plan, and training for different members of the lifting team, including the crane operator, lifting supervisor, rigger and signalman.


 Lorry Cranes are referenced in the Workplace Safety and Health (Operation of Cranes) Regulations 2011 as a lorry incorporating an articulated arm mounted on the lorry which is used for loading, unloading and lifting of materials or goods.


The WSH Council set up the National Crane Safety Taskforce in mid 2009 to review the safety of crane operations and make recommendations for industry-level mprovements. The Taskforce announced its threepronged strategy in Sept 2009 to enhance training, outreach efforts and new standards/code of practice.


Under the WSH (Operation of Cranes) Regulations, new lorry crane operators will  have to complete the LCOC and pass the assessments before he is allowed to  operate a lorry crane.


The new course will ensure that all operators are properly trained to be able to  operate lorry cranes competently and safely by September 2013. Besides training  the operators on the roles and responsibilities of a lorry crane operator, the course will also cover other key topics such as principal components of a lorry crane, how an operator can identify possible hazards, implement control measures and perform safe lifting operations.


Experienced lorry crane operators who have at least three years of experience in operating lorry cranes and can show relevant proof of his competency and/or experience will be exempted from the LCOC and allowed to take the Lorry Crane Operator Competency Test (LCOCT) directly. Those who do not pass the test will be required to enrol for the LCOC. The course is available for registration with the BCA Academy from January 2012. More details on LCOC and LCOCT can be found in Annex A.


Mr Ismadi Mohd, Deputy Director of Equipment Safety with the Ministry of  Manpower’s Occupational Safety and Health Division and a member of the Crane  Safety taskforce said, “Over the past five years, unsafe lorry crane work practices  resulted in 4 fatalities across more than 40 incidents. The Ministry’s investigations show that many of these incidents could have been prevented if lorry crane operators were better trained and adhered to proper safe work procedures while  carrying out crane operations. This shows the need to enhance the training and  competencies of our operators.”


Leading this enhancement is Mr Tan Wee Seng, Chairman of the WSH Council-led National Crane Safety Taskforce. He said, “Following extensive discussions with lorry crane stakeholders, we have found that training the operators will be pivotal to improving safety standards as they are primarily the ones in charge of the lorry cranes on-site. Crane accidents have potential risk on the lives of the public, workers and the crane operators. In order to give the industry sufficient time  to comply, lorry crane operators have nearly two years till 1 September 2013 to be  certified. However, we urge all lorry crane companies to send their operators for  training early so that they are better equipped to handle any lifting operations safely.”

Supporting this latest move is Mr Dave Ng, Honorary Auditor of the Singapore Cranes Association. Mr Ng said, “We have reviewed the ways we can enhance the safety of lorry crane operations. While we advocate the use of safe work procedures and the lifting plan, it was clear that the operators’ capability to perform the work safely was critical. Hence, the move to train the operators is the right thing to do.

Given the large numbers, it is good that we have been given almost two years to get  our operators trained.”

Lorry Crane Operator Course

Legal Requirement Under the Workplace Safety and Health Act Chapter 354A, Workplace Safety and Health (Operation of Cranes) Regulations 2011 Part 2 (General Provisions), states that:

4. No person shall operate a lorry loader unless –
he has successfully completed a training course, acceptable to the Commissioner, on the operation of a lorry loader; if required by the Commissioner, he attends re-training on the operation of a lorry loader and successfully com pletes such re-training; and
if required by the Commissioner, he produces a current medical certificate from a registered medical practitioner certifying that he is medically fit to operate a lorry loader

5. It shall be the duty of the responsible person to ensure that no person is allowed to operate a lorry loader unless the person satisfies the requirements referred to in paragraph 4.

Business Under Surveillance (BUS)

The Business Under Surveillance (BUS) Programme is a systemic intervention tool to regulate poor performing companies to focus on developing and implementing a robust safety and health management system to improve their WSH performance.
This programme is divided into two phases – the Assessment and the Surveillance phase. In the Assessment phase, companies who have had fatal accidents, demonstrated poor WSH management (such as poor site conditions that result in Stop Work Orders) or have had accumulate a number of demerit points would typically be considered for entry into the BUS programme. A thorough review of the implementation of the risk assessment and the strength of the management system would be conducted. If the company fails the assessment, they will be subjected to close surveillance.
In the Surveillance phase, OSHD requires the company's management to develop and commit to a comprehensive and sustainable Action Plan. The company is held accountable to their proposed Action Plan and reports the implementation progress on a regular basis to OSHD. In addition, inspections are carried out frequently by the OSHD Surveillance Branch to verify the progress made. The company will exit from the programme upon demonstrating significant improvement in its WSH performance and management.

Cluster operations

Cluster Operations (COPS) is a workplace inspection programme where selected cluster of workplaces are pre-announced on this website before the inspections take place. This is to encourage affected companies to take the initiative to improve safety and health standards within their workplace prior to MOM's inspections. Links to online guidelines, technical advisories and compliance assistance tools will be provided to assist companies in their preparation for the workplace inspections.

In certain clusters of workplaces, upstream stakeholders of these workplaces (e.g. client of affected companies) will also be engaged to solicit improvements in workplace safety standards within the cluster.

Outcomes of the workplace inspections conducted and common contraventions detected will be shared after each operations, to facilitate companies in the detection and rectification of weak areas within their workplaces.

Upcoming Cluster Operations are published as highlights in the Workplace Safety and Health section.

MANDATORY HIGHER GREEN MARK STANDARD FOR GOVERNMENT LAND SALES SITES IN SELECTED STRATEGIC AREAS

To maximise the potential for cost-effective energy savings in our built environment, it was announced in BCA’s 2nd Green Building Masterplan in 2009 that projects developed on land sold under the Government Land Sales (GLS) Programme sites in the selected strategic areas will be subject to higher Green Mark Standards.

 
SCOPE AND DETAILS

This requirement will apply to buildings works related to any building on land sold on or after 5 May 2010 under the Government Land Sales Programme in selected strategic areas. The building works subject to this requirement are to be designed to meet the prescribed Green Mark Certification as shown in the following table.

Selected Strategic Areas Exact Location to refer to the Building Control (Environmental Sustainability ) Regulations 2008	Requirements for building wholly or partly within area that is on land sold under the Government Land Sales Programme
Marina Bay	Green Mark Platinum Rating
Downtown Core – including areas within the CBD located next to Marina Bay	Green Mark GoldPlus Rating
Jurong Lake District	Green Mark GoldPlus Rating
Kallang Riverside	Green Mark GoldPlus Rating
Paya Lebar Central	Green Mark GoldPlus Rating

For building works that are subject to this requirement, the qualified person and appropriate practitioners need not submit their declarations of the Green Mark scores along with the building plan submission. Instead, the qualified person should ensure that, prior to the building plan submission, an application is made to BCA for the project to be assessed certified under the certification standards approved by the Commissioner of Building Control. Upon completion of the building works, the qualified person should submit the Green Mark Certificate showing the Green Mark Certification rating achieved for the project along with his application for a temporary occupation permit (TOP) or certificate of statutory completion (CSC). It is important to note that the prescribed Green Mark Certification rating for the building has to be obtained before a TOP/ CSC can be granted.

The certification standard will be revised from 1 Dec 2010 in tandem with the changes in the Green Mark Criteria.  The compliance with the respective certification standards will be based on the tender award letter issued by URA to the successful developer under the Government Land Sales (GLS) programmes for the selected strategic areas and as stated in the table below.

MANAGEMENT OF TOXIC INDUSTRIAL WASTES IN SINGAPORE

MANAGEMENT OF TOXIC INDUSTRIAL WASTES IN SINGAPORE

1 Introduction

1.1 Wastes may be defined as materials which no longer can be used for the purposes they were intended for originally. Toxic industrial wastes are wastes which by their nature and quality may be potentially detrimental to human health and/or the environment and which require special management, treatment and disposal.

1.2 In view of Singapore’s small land area with limited land and water resources, the siting of industries has to be carefully planned and managed. In addition, industries are required to design their manufacturing processes and provide pollution control facilities to comply with pollution control requirements on emission of air pollutants, discharge of industrial effluent, management of hazardous substances and toxic industrial wastes.

1.3 There are currently more than 2,000 companies in Singapore which handle or use hazardous chemicals. The use of these chemicals generates a wide variety of toxic industrial wastes. The main types are spent acids, spent solvents, spent etchants, waste oil and other waste sludge.

2 Strategy for Control of Toxic Industrial Wastes
2.1 The key elements in Singapore’s strategy to control toxic industrial wastes and ensure their safe treatment and disposal are as follows:
(i) avoid generation of intractable wastes;
(ii) encourage waste minimisation;
(iii) encourage waste reuse, recovery and recycling;
(iv) regulate collection, treatment and disposal;
(v) monitor and audit collection, treatment and disposal; and
(vi) promote and support educational and training programmes.
2.2 All new industrial developments are screened by PCD at the planning stage. One of the key areas checked in this screening
2
process is the generation and disposal of wastes from proposed industrial developments. PCD will approve the proposed industrial development only if the wastes generated could be safely disposed of in Singapore. This avoids the generation of intractable wastes that cannot be safely disposed of in Singapore.
2.3 In addition, PCD will require industries to use processes that minimise waste generation or facilitates the reuse, recovery and recycling of the wastes. Industries also need to incorporate measures into the design of their facilities to ensure wastes generated can be properly handled and managed. At the building plan stage, checks are made to ensure that these measures are incorporated into the design of the plants.
2.4 PCD has encouraged the setting up of specialised waste recycling, treatment, and disposal plants. There are currently about 100 such plants in Singapore, treating and recycling a wide range of toxic industrial wastes. Some of the toxic industrial wastes collected and recycled by these plants for reuse are discussed in Section 5.
2.5 The setting up of specialised waste recycling, treatment and disposal plants serve to help industries, especially the smaller companies, which may generate small quantities of special wastes but find it impractical or uneconomical to install, operate and maintain a waste treatment facility because of cost, lack of expertise or space constraint.
2.6 The collection, recycling, treatment and disposal of toxic industrial wastes are controlled under the Environmental Public Health Act (EPHA) and the Environmental Public Health (Toxic Industrial Waste) Regulations (TIWR).

3 The Environmental Public Health (Toxic Industrial Waste) Regulations (TIWR)
3.1 The control on the import, sale, supply, receipt, transport, treatment and disposal of toxic industrial (hazardous) wastes are regulated under the TIWR. Industrial wastes controlled under the TIWR are listed in the Schedule of the Regulations as waste streams from specific industrial activities, wastes with specified toxic components and as specific categories of wastes. The list includes spent acids, alkalis, wastes containing gallium arsenide, spent etching solutions containing copper from printed circuit board manufacturing, etc. The list is at the Annex.
3
3.2 In order to facilitate controls and proper management, the functions and responsibilities of key persons involved in handling of the toxic industrial wastes are clearly delineated in the TIWR. The key persons include the following:
(a) Generator of wastes
(b) Collector
(c) Carrier or transporter
(d) Driver
3.3 The generator will have to treat the wastes in an approved in-house waste treatment plant and dispose of the residues, if any, at NEA sanitary landfill site. Alternatively, the generator can engage a licensed toxic industrial waste collector to collect his wastes for treatment and disposal.
3.4 A toxic industrial waste collector is a person who receives toxic industrial wastes for storage, reprocessing, treatment and disposal. He has to obtain a licence from PCD to collect specific toxic industrial wastes that are listed in his licence and confine his wastes storage and treatment activities to approved premises and facilities.
3.5 Written transport approval from PCD is also required for the transportation of wastes in quantities which exceed those specified in the TIWR. The responsibilities of the following key persons in the transportation are clearly defined in the TIWR:
(a) Consignor - the person who presents a consignment of controlled wastes for transport. The consignor can be either the generator or the licensed collector. Transport approval shall be obtained from PCD to transport the wastes.
(b) Carrier - the person who undertakes the transport of the controlled wastes. He can either be the generator, the licensed collector or the transport company engaged by either one of them.
(c) Consignee - the person who receives the controlled wastes. He is usually the licensed collector.
4
(d) Driver - the driver of the vehicle transporting the toxic industrial wastes.
3.6 To prevent illegal dumping and disposal of toxic industrial wastes, the movement of every consignment of wastes from a generator through a carrier to a collector is tracked by means of an Internet-based electronic submission of consignment note system (known as the e-Tracking System).

4 Waste Minimisation
4.1 The Waste and Resource Management Department (WRMD) of NEA is to formulate policies to promote and spearhead waste minimisation in Singapore. WRMD develops, promotes and oversees the implementation of programmes on waste minimisation and recycling. It also carries out studies to enhance waste recycling.
4.2 WRMD together with PCD works closely with the industries to promote waste minimization. Some of the activities promoted by WRMD and PCD are as follows:
(a) Waste Exchange
NEA helps to link industries for exchange of wastes. Waste to one company may be a resource to another. For example, waste alkali generated by one company could be used by another company to neutralise the acidic wastes. This would minimise the ultimate quantity of wastes to be disposed of.
(b) Use of Clean Technology
At the planning consultation stage, NEA advises and encourages industries to use clean technologies which minimise waste generation.
(c) Reuse and Recycling
NEA encourages the recycling and reuse of wastes and assists in the setting up of waste recycling plants. Some of the wastes that are being recycled and reused in Singapore are discussed in Section 6.
(d) Waste Audit
NEA encourages those industries that generate large quantities of wastes to carry out waste audit. A waste audit is designed to achieve maximum resource optimisation and improved process performance. The audit enables one to take a comprehensive look at the process to understand the material flows and to focus on areas where waste reductions are possible. The waste audit can be carried out to cover a complete process or to concentrate on a selection of unit operations within a process. There are competent consultants in Singapore to carry out such waste audit for industries.

5 Some Practices Adopted for Recycling and Reuse of Wastes
5.1 A large amount of industrial wastes generated and collected in Singapore by the licensed collectors are either recycled, reused or have valuable components extracted and recovered before disposal. Such wastes include spent solvents, spent etchants and photographic wastes.
5.2 Spent solvents are generated by a wide range of industries. Each year about 50,000 m3 of spent solvents are collected by the licensed collectors. The spent solvents collected include acetone, chloroform, ethyl acetate, methylene chloride and toluene. About 22,500 m3 of spent solvents are recovered by distillation. The practice adopted by these collectors is usually batch (differential) distillation. The equipment comprises a still to vapourise the solvents, a condenser to condense the vapours and collecting vessels to collect the condensate and the residues. The recovered solvents are sold for reuse by industries. The remaining 27,500 m3 of spent solvents that could not be recovered are used as supplementary fuel for toxic waste incinerators.
5.3 Printing and film processing activities generate photographic wastes such as spent fixers and bleaches. Each year about 1,000 m3 of such wastes are collected and treated. These wastes contain silver in solution. An effective and commercially viable method, the electrolytic extraction process, is used to recover the silver. In this process, carbon is used as the anode and a stainless steel drum as the cathode. The silver is deposited on the stainless steel drum. The extracted silver has a purity of more than 90 %. The remaining liquid from the electrolysis process is treated and neutralised in a waste water treatment plant before discharge into the sewers.
5.4 Etching is an important process used in the electronics industry especially in the manufacture of the printed circuit boards. The process generates spent etchants such as cupric chloride etchants,
6
ferric chloride etchants and ammonia etchants. Each year about 23,000 m3 of spent etchants are generated and treated in Singapore. Spent ferric chloride etchants are regenerated using scrap iron and chlorine. In this process, scrap iron is first added to the spent etchant and the copper sludge that precipitates out is collected and sold as a valuable by product. The etchant is next regenerated by passing chlorine through it. The regenerated etchant is sold for reuse.
6 Monitoring And Enforcement
6.1 Any control system, no matter how well crafted will not be effective without rigorous enforcement. Enforcement will ensure the minority of companies that violate the controls are penalised accordingly and would not gain unfairly from their violations. Without rigorous enforcement, companies that originally comply with the controls may become complacent and pay less attention and effort to ensure their operations continue to be safely managed.
6.2 Monthly checks are conducted on premises of toxic industrial waste collectors and the records are audited to ensure requirements on collection, storage, treatment and disposal of toxic wastes are complied with.
7 Transboundary Movements Of Hazardous Wastes
7.1 Before acceding to the Basel Convention, Singapore had already adopted and practised the principles of the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and its Disposal in controlling the export, import and transit of toxic industrial wastes or hazardous wastes.
7.2 Singapore acceded to the Basel Convention on 2 Jan 96 and on 16 Mar 98 enacted The Hazardous Waste (Control of Export, Import and Transit) Act and its Regulations to strengthen the control on export, import and transit of hazardous wastes in accordance with the principles and provisions of the Basel Convention.
7.3 Under the Hazardous Waste Act and its Regulations, any person who wishes to export, import or transit hazardous wastes shall obtain a permit from PCD. PCD has adopted the Prior Informed Consent (PIC) procedure of the Basel Convention in granting any permit for the export, import or transit of hazardous wastes.
7
8 Training
8.1 NEA collaborates with local institutions and trade associations such as the universities, the Singapore Chemical Industry Council, the Society for Loss Prevention in the Oil, Chemical and Process Industries, etc, to organise and conduct workshops, conferences and seminars on the safe handling and disposal of toxic industrial wastes for local industries.
8.2 NEA also works together with the Occupational Safety and Health Division of the Ministry of Manpower to conduct training courses on safe practices on handling of toxic industrial wastes for workers in the industries.
9 Conclusion
9.1 In addition to regulatory controls, the co-operation of industries in ensuring that toxic industrial wastes are properly managed and disposed of in Singapore is essential. NEA will continue to work with industry and institutions in promoting better management and disposal of toxic industrial wastes through joint research and educational programmes.
9.2 NEA will continue to participate in international events on the Basel Convention and adopt and practise the principles of Basel Convention in dealing with transboundary movements of toxic industrial wastes.

Management of Hazardous Substances

Management of Hazardous Substances

1 INTRODUCTION
Singapore is an island of about 620 square kilometres in area. The average population density in Singapore is about 4,000 people per square kilometre. Such high population densities make it imperative for hazardous substances to be controlled so that public exposure to accidental release is, if not avoided, minimised.
In addition, large parts of Singapore are used as water catchment areas. It is necessary to ensure that chemical storage facilities and transport avoid such areas as far as possible. This is to prevent pollution and to protect drinking water sources against contamination.
The awareness of the hazards or risks posed to both human health and the environment from the manufacturing, storage, transport, and use of hazardous chemicals has come about in recent years as a result of a number of reported major industrial accidents in both developed and the developing countries. Two well known catastrophic incidents occurred in the mid 1980s in the less developed countries. These were the release of toxic methyl isocyanate from a pesticide factory in Bhopal, India and the explosions and fires at an LPG installation in Mexico. Both incidents caused great losses of lives.
In Singapore, the Government has implemented measures to control and minimise the risks from industrial developments handling large quantities of hazardous substances not only to protect workers within the hazardous plants but also the general public and the environment.
Pollution Control Department (PCD) of the National Environment Agency controls toxic and environmentally hazardous chemicals under The Environmental Protection and Management Act (EPMA) and The Environmental Protection and Management (Hazardous Substances) Regulations.
Flammable petroleum products in Singapore are controlled under the Fire Safety Act by the Fire Safety & Shelter Department (FSSD) of the Singapore Civil Defence Force (SCDF).
Radioactive substances are controlled by the Centre for Radiation Protection and Nuclear Science (CRPNS).
2 POLLUTION CONTROL DEPARTMENT
CONTROL STRATEGIES
The hazardous chemicals controlled by PCD (see Table 1) are those that:

• Pose a mass-disaster potential
• Are highly toxic and polluting
• Generate wastes which cannot be safely and adequately disposed of

In Singapore, the control of hazardous chemicals are implemented mainly through the following measures:

• Planning control
• Licensing control
• Enforcement

PLANNING CONTROL
On new developments, PCD checks and ensures that new residential and industrial developments are properly sited and are compatible with surrounding land use. PCD also imposes environmental pollution control requirements to be incorporated into designs of developments to minimise pollution and to mitigate pollution impact on surrounding developments.
The Jurong Town Corporation (JTC) and Housing Development Board (HDB) are developing agencies for industrial land and premises and they consult PCD on the allocation of industrial premises. PCD assesses and evaluates the environmental impact of the proposed industries to ensure that they do not pose unmanageable health and safety hazards and pollution problems. A proposed industry will be allowed only if emissions of pollutants can comply with standards, wastes can be safely managed and properly disposed of, and the factory can be sited in a suitable industrial estate.
For major developments, PCD requires developers to carry out pollution control assessment for their proposals. Examples of major developments include industries involving the use or storage of hazardous chemicals in bulk quantities, port development, landfill site, etc. The study includes an assessment of all pollution impact on the environment and recommendation of measures to mitigate such impact. PCD will issue clearance to the proposed development only if its evaluation of the study reports confirms that pollution impact could be mitigated to acceptable levels.
In addition, PCD encourages industries to reuse, recycle and recover their by-products to minimise waste generation. Disposal of wastes by landfill is only used as a last resort. For proposed industrial developments, PCD also checks and ensures that clean technology is adopted in industrial processes to conserve resources, and minimise pollution.
After a proposed development has been granted planning approval, a developer can proceed to submit building plans to the Building Control Division (BCD) of the Public Works Department for approval. Under the current procedure on building plan approval, the developer is also required to submit building plans to technical departments including PCD for clearance on technical requirements. PCD checks the building plans of the development for compliance with technical requirements on environmental health, drainage, sewerage and pollution control. In addition, PCD also checks and ensures that pollution control measures are incorporated into the design of buildings.
After the completion of a development, PCD inspects it to ensure compliance with technical requirements before granting clearance to BCA for the issue of Temporary Occupation Permit (TOP)/Certificate of Statutory Completion (CSC) to the completed development.
Industries are required to apply for written permission, licence and permits from PCD before they can start operation.
LICENSING CONTROLS
Licensing controls are implemented under the Environmental Protection and Management Act (EPMA) and the Fire Safety Act. The licensing controls prevent unauthorised persons from handling such substances and ensure proper safeguards are taken at all times in the handling of the substances to prevent accidental releases and mitigate the adverse effects if they occur.
The following Licensing Controls over the import, transport, storage and use of hazardous substances are implemented under The Environmental Protection and Management Act (EPMA) and its Regulations:
Hazardous Substances Licence Control
Any person who wishes to import, sell or export any hazardous substance controlled under the Environmental Protection and Management Act (EPMA) must obtain a Licence.
A licence will be issued to a person if:

• he could show proof that the Hazardous Substances will be stored safely in an approved location and in compliance with the storage requirements;
• the use of the Hazardous Substances at his factory has been approved;
• he has sat and passed the Management of Hazardous Substances Course conducted by Singapore Environment Institute (SEI); and
• his academic qualification must be at least a technical diploma.

Hazardous Substances Permit Control
Any person who wishes to purchase, store and/or use any hazardous substance controlled under the Environmental Protection and Management (Hazardous Substances) Regulations must obtain a Permit.
A Permit will be issued to a person if:

• he could show proof that the Hazardous Substances will be stored safely in an approved location and in compliance with the storage requirements;
• the use of the Hazardous Substancesat his factory has been approved; and
• he has declared that he has read and understood the Environmental Protection and Management Act (EPMA) and its Regulations.

The Licence/Permit application form is in Annex 9. In addition, the public can submit an electronic application for a Hazardous Substances Licence/Permit via the Internet. The Internet address is: http://app1.env.gov.sg/pcls/index.jsp
Transport Approval Control
Any person who wishes to transport any hazardous substance in quantities exceeding those specified in the Environmental Protection and Management (Hazardous Substances) Regulations (see Table 2) must obtain a Transport Approval. The limits varies from 0 kg for highly toxic chemicals such as organochlorines pesticides to 1000 kg for corrosives such as sulphuric acid.
A Transport Approval will be issued to a person if:

• he holds a Licence to handle hazardous substances,
  he could show proof that the Hazardous Substances will be transported safely in compliance with the transportation requirements.

The licence holder can also submit an application for a Hazardous Substances Transport Approval via the internet.
Import Control
The most effective stage of control to ensure that all chemicals that enter Singapore can be and will be safely managed and handled at all times by approved competent licence holders is at the import stage.
Under the Environmental Protection and Management Act (EPMA), all import of Hazardous Substances listed under Second SchedueI of the Act must be approved by PCD. PCD will approve the import only if:

• the Hazardous Substances are stated in the importer's licence,
• there is a valid transport approval for the Hazardous Substances if the Hazardous Substances are to be transported out of the port.

TECHNICAL REQUIREMENTS UNDER LICENSING CONTROLS
The Environmental Protection and Management Act (EPMA) and its Regulations provide provisions for technical requirements to be imposed and complied with to ensure the safe management and handling of hazardous substances and to prevent an accident from occuring. These technical requirements are briefly described below.
Storage Requirements
The storage area should be sheltered; fenced-up; under lock and key; provided with kerb/hump all round the storage area; provided with fire protection and safety facilities; equipped with leak detection and warning devices and emergency scrubbing systems for storage of toxic gases.
The containers and storage tanks for the chemicals must be designed, manufactured and tested in accordance to an internationally-acceptable standards.
Hazardous Substances Licence and Permit holders must keep records of stock movements of the hazardous substances in accordance to the formats specified by PCD.
Adequate emergency action plan (see Annex 1) for dealing with any accidental release of chemicals must be drawn; with adequate stock of emergency equipment such as neutralising agent, adsorbents, oversized drums, protective gears, etc on kept on standby.
The implementation of a safety audit procedure is strongly encouraged to systematically identify and rectify weaknesses in the management system and practices of handling hazardous chemicals on a regular basis. Attached are the elements that should be audited and a list of consultants that are able to conduct such audits. (see Annex 2 & 3)
Transport Requirements
The containers and tankers used for bulk chemical transportation must be designed, manufactured and tested in accordance to an internationally-acceptable standards. The tankers must be certified by an approved third party inspection body to have met the stipulated standards (see Annex 4) before it can be used for transportation on Singapore roads.
The containers, tankers and vehicles must be properly labelled and carry appropiate hazard warning panels.
All transportation of controlled Hazardous Substances must strictly adhere to NEA's approved routes and must be between 9.00 am and 5.00 pm (Monday to Saturday excluding Sundays and Public Holidays).
All drivers must be trained in the handling of accidental spills and have attended the HazMat Driver Course conducted by SCDF's Civil Defence Academy or Singapore Port Institute (PSA Institute). Drivers renewing their Hazardous Material Transport Driver Permit (HTDP) are required to attend  the HazMat Driver's Course once every 2 years.
An adequate transportation emergency response plan (TERP) (see Annex 5) must also be put up to deal with any accidental release of the hazardous substances; with adequate stock of emergency equipment carried on the vehicles; such as chemical fire extinguisher, neutralising agent, adsorbents, oversized drums, protective gears, etc.
The consignor has to prepare a set of instructions for the carrier or transport company containing the following :-

• information on the hazards of hazardous substance and safety precautions for its safe handling,
• restrictions on the mode of transport and any necessary routing instructions,
• special operational requirements for loading, unloading and transport or a statement that none is needed,
• emergency response plan for transportation of the hazardous substances.

The carrier is required to obtain a set of the above instructions from the consignor and be conversant with the information it contained before proceeding to transport the consignment of the hazardous substance. The carrier must instruct and train his driver to ensure he understood the instructions given and is capable of carrying them out effectively. All documents pertaining to the chemicals transported (i.e. MSDS, transport approval and all emergency response, spill control and first aid equipment) should be kept within ready reach in event of emergency.
The consignor has to ensure that the instructions given to the carrier are accurate and sufficient to enable the carrier to carry out the transportation safely. The consignor is also required to be present on-site to personally deal with any chemical release during transportation.
Tanks of road tankers and tank containers used for transporting hazardous substances must meet approved standards of design, construction and testing. The design of the tanks must be reviewed and its construction surveyed by an approved third party inspection body. Once the third party inspection body is satisfied that the tank or tank container meets the approved standards, it will issue an initial inspection certificate. Under the approved standards, the tank and tank container must undergo periodic inspections.
The following standards are acceptable:

• European Agreement of Road Transport of Dangerous Goods (ADR Standards)

The carrier needs to ensure that the vehicle and its tanks or containers are properly labelled in accordance to the Singapore Standards 286, 'Cautionary Labelling for Hazardous Substances'.
Labels are given for each class of hazardous substances and should be affixed on packagings and the vehicle. Road tankers and vehicles carrying hazardous substances in tank containers should have Emergency Information Panels. These are hazard warning panels containing the following emergency information :-

• the appropriate class label and subsidiary risk label, if any
• the correct technical name of the substance
• the UN number of the substance
• the Hazchem code number
• contact numbers and names of company and emergency response authority

EMERGENCY RESPONSE PLAN
Notwithstanding the controls and precautions taken, one cannot rule out the possibility of spillages and accidental releases of hazardous substances during transportation. With well drawn up emergency plans and proper training, such releases can be effectively contained and the damage to the environment and dangers to the health and safety of public minimised.
As a condition for granting licences and transport approvals, companies are required to put up emergency response plans.
The plan must be comprehensive and should contain the following key elements :-

• notification procedures; (persons and authorities to contact and how to contact)
• emergency procedures to contain and decontaminate spills; (immediate actions to be taken by driver/ground staff and actions to be taken by the company upon being informed)
• emergency equipment to be carried on the vehicle and at base such as personal protection equipment, absorbents, neutralising solutions and salvage drums;
• Material Safety Data Sheets of the hazardous substances transported.

The emergency response plan (ERP) shall be vetted and approved by SCDF before a Transport Approval may be issued.
Under the provisions of The Environmental Protection and Management (Hazardous Substances) Regulations, in the event of a chemical fire / release, the licence holders\transport approval holders are required to:

• block off the area contaminated by the hazardous substance;
• notify SCDF and the PCD;
• take immediate action to have the area decontaminated and return the situation to normal.

ENFORCEMENT
Under the Act and its Rules, PCD officers are empowered to carry out regular inspection to check into the following aspects of controls:

• Import, purchase and sale of Hazardous Substances
• Storage
• Transportation
• Labelling
• Maintaining and updating of records and sales documents
• Ensure that all hazardous substances are safely disposed of

PCD officers are authorised to:

• check and search premises;

CONCLUSION
Hazardous chemicals have the potential to seriously endanger life and pollute the environment. Such chemicals have to be carefully managed at all time to prevent any accidental release. The successful implementation of a chemical safety programme requires co-operation from the industries to manage their hazardous chemicals properly and the support of the general public.
