Smaller-scale Construction Works Safety

 Smaller-scale Construction Works Safety

In 2023, 11 fatalities and 100 major injuries resulting from smaller-scale construction works (e.g. addition and alteration works, renovation and facility management)  These smaller-scale works are of major concern as they caused 66% of the fatal and major injuries in the construction sector for 2023.

Common failure observed include the use of equipment in poor condition (e.g. damaged ladders, damaged hoarding supports), poor workplace housekeeping (e.g. loose electrical cables left on the ground), inadequate fall prevention/protection measures, use of improper footwear, and missing safety data sheets for chemicals used at the workplace.

The Ministry of Manpower (MOM) will be conducting inspections targeting smaller-scale construction projects (including those in commercial malls) with a contract value of less than $5 million In the upcoming months

Below are some good workplace safety and health (WSH) practices commonly adopted by companies to prevent injuries arising from hazards found in smaller-scale construction works. The WSH Council urges companies to conduct proper risk assessments and adopt the following good practices to be well prepared for MOM’s upcoming inspections.

Workplace Noise Induced Deafness Prevention

Workplace Noise-Induced Deafness Prevention

Do you know what is the leading occupational disease in Singapore? Yes your are correct, it is the Noise-induced deafness (NID) .

Workers may be exposed to excessive noise emitted by equipment, machinery or even processes at the workplace. Hearing loss is an irreversible process and can lead to communication difficulties, disruptions in job performance, and impact one’s livelihood and quality of life.

The Ministry of Manpower (MOM) will be conducting inspections on noisy work environments in the manufacturing sector In the upcoming months

Below are some of the good practices adopted by companies to protect their workers' hearing and urge more companies to do the same:

Measure workplace noise

Workplace noise monitoring determines noise levels in the work environment to assess if workers are at risk of hearing loss.

• Conduct a site walkabout to identify noisy equipment, tools and work processes. Common sources of noise at workplaces include:

Engage a competent person (i.e. a noise monitoring officer) to measure:

• Noise levels emitted by the noisy equipment, tools and work processes; and
• Noise exposure (e.g. using personal dosimetry) of any worker exposed to excessive noise.

Develop action plans based on the noise monitoring report:

• Implement noise reduction measure(s) for each identified noise source.
• Designate each identified noisy work area as a “hearing protector zone” with warning signs displayed.
• Send workers identified to be exposed to excessive noise for yearly audiometric examination.

Manage workplace noise levels

Reduce a worker’s exposure to noise and prevent NID by implementing these noise control measures:

Examples of noise reduction measures implemented by companies

Monitor workers’ hearing through audiometric examinations

Audiometric examinations are hearing tests to determine if a worker has normal hearing, early NID or advanced NID. Yearly audiometric examinations allow for early NID detection, so that immediate intervention can be carried out to prevent further hearing loss.

• Send new hires for audiometric examination before or within three months of starting employment.
• Send existing workers who are exposed to excessive noise for yearly audiometric examinations.

Confirm that the hearing tests are carried out by trained personnel in an audiometric booth. For more accurate results, limit the worker’s exposure to noise for at least 16 hours before the hearing test.

Support workers diagnosed with occupational NID:

• Provide them with suitable hearing protectors and remind them to wear them.
• Redeploy them to less noisy work activities and/or reduce their time spent in noisy work environments.
• Arrange additional follow up audiometric examinations and consultations as deemed necessary by the doctor.

Note that employers are required to submit an incident report to MOM for each worker diagnosed with occupational NID

Confined Spaces Safe Work Practices

Confined Spaces Safe Work Practices

Working inside a confined spaces can be hazardous due to the possibility of explosions, fires, poisonous fumes, or oxygen shortages. Three workplace deaths occurred between 2021 and 2023 as a result of working in confined spaces. And 2 workers lost their lives in the first half of 2024 as a result of being overexposed to hydrogen sulfide after entering a service tunnel to do tank cleaning tasks.

The WSH Council has compiled the following good practices for confined space work. Companies are reminded to implement these practices to protect their workers from confined space hazards.

Construction Site Workplace Fatality

SINGAPORE – Construction site workplace fatality involving a local site engineer and a Bangladeshi construction worker. Both died on Sept 17 after they were struck by heavy machinery at a worksite in Lentor Avenue for the upcoming North-South Corridor.

Singapore Civil Defence Force paramedic pronounced the Bangladeshi worker,39 dead at the scene while the engineer, 38, was unconscious when taken to Khoo Teck Puat Hospital, where he died due to his injuries.

Two other workers, aged 32 and 47, were also taken to the same hospital after the accident, which happened at about 1.20pm.

According to LTA the four were assembling a winch drum that was resting on two concrete blocks when the winch, which is typically used in the lifting of heavy materials, slid off the blocks and struck them

The Ministry of Manpower (MOM) said that as a general safety measure, heavy machinery or structures must be secured in a stable manner to reduce the risk of slipping or toppling

**Cause of Accident**: 

The winch drum, used for lifting heavy materials, slid off its concrete supports while the workers were assembling it

**Ongoing Investigation**: 

The Ministry of Manpower (MOM) and Land Transport Authority (LTA) are investigating the incident, and LTA has paused work to review safety protocols. 5. **Previous Safety Incidents**: This is the second fatal accident at a North-South Corridor construction site in a year. At this point in time, the root causes are not yet known as the investigation is still ongoing

MOM Revised Heat Stress Framework

REVISED FRAMEWORK TO GUIDE EMPLOYERS AND PROTECT OUTDOOR WORKERS AGAINST HEAT STRESS

With global warming, rising temperatures in Singapore will place workers, especially outdoor workers, at an increased risk of heat stress. Unlike the general population, outdoor workers have less discretion over their work activities, and may be more vulnerable to heat stress. The Ministry of Manpower (MOM), in consultation with the industry and tripartite partners, has reviewed our heat stress management measures to ensure outdoor workers are adequately protected at varying temperatures, while allowing flexibility for employers to adjust and implement measures based on their localised conditions. 

The framework for outdoor workers has been aligned with the three-tier Heat Stress Advisory for the general population, which is based on the Wet Bulb Globe Temperature (WBGT)[1]. The framework includes required measures that are critical in mitigating the risk of heat stress, such as heat acclimatisation, regular hydration, monitoring of WBGT and provision of adequate rest breaks under shade, that must be implemented. There are also recommended practices, such as close monitoring of worker’s health condition and provision of ventilation, for employers to consider at the different WBGT bands. The framework is appended in the Annex.

MOM will conduct inspections at workplaces to ensure that required measures under the framework are implemented. More information on the framework can be found at go.gov.sg/heatstress-outdoorwork

Annex

Note: Bold items are required measures that must be implemented at the respective WBGT bands.

* Workers vulnerable to heat stress include:  

· Older workers above 65 years old of age  

· Pregnant workers  

· Overweight or obese workers  

· Newly assigned to outdoor work 

· Unacclimatised to working in hot environments such as new or returning from countries with cold climate 

· Returning from long leave of more than 1 week 

· Currently unwell or recovering from illness 

· With personal risk factors such as chronic diseases, medication use, or history of heat injury

Note: 

This list is not exhaustive and neither covers all individual variabilities nor all conditions. 

Workers should consult a medical doctor if they have any of the above health related conditions and wish to be certified fit to work outdoors. 

Workers with other medical conditions or who are uncertain should consult a medical doctor.

Employers who wish to deploy vulnerable workers have a duty to ensure they are fit for outdoor work. They should seek the worker’s consent and make provisions for the worker to consult a medical doctor. 

Hazards of Overfilling Skid Bin

 Advisory to Waste Generators and General Waste Collectors (GWCs)

SINGAPORE : Joint circular from WSH Council , LTA and NEA seek the cooperation of waste generators and other users of OTCs such as companies and Town Councils to help ensure that the OTCs are not overfilled at their premises.

Exceeding the Maximum Laden Weight of vehicles attracts a fine

Overfilled OTCs that exceed the maximum laden weight (MLW)1 is a hazard to both drivers and other road users. It is an offence under the Road Traffic Act for vehicles that exceed the MLW to be used on the road; and vehicles found in violation of load limits may face fines of up to $1,000 and/or imprisonment for up to 3 months for first-time offenders, and doubled for repeat offenders.

Overfilled OTCs Should Not Be Hauled for Safety Reasons

Under the licensing conditions, the GWCs are required to ensure that the OTCs are not overly filled with waste and that waste must be securely covered during transportation. Failure to do so could pose safety hazards to other road users, e.g. waste could drop off on the road. Similarly, this would compromise the safety of the drivers and staff of the disposal facilities. 

Hence, OTCs should only be filled up to their brim, which also makes it easier for the OTCs to be securely covered for transportation.

GWCs have the rights to reject collection of overfilled OTCs if waste generators do not cooperate and ensure no overfilling of OTCs. Errant GWCs found hauling overfilled OTCs may

be subject to enforcement action.

Construction Site Workplace Fatality

SINGAPORE: A 35-year-old construction worker died  after he was struck by a reversing dump truck at a worksite at a junction of Tanah Merah Coast Road and the Changi East development, said the Ministry of Manpower (MOM) on Friday

A 36-year-old man was arrested for causing death by a rash or negligent act, said the police, adding that investigations are ongoing.

The construction worker was employed by Hua Hao Development, while the occupier of the worksite is Huationg Contractor, said an MOM spokesperson in response to queries from CNA on Friday.

"As a general safety measure, a traffic management plan must be implemented to ensure the safe movement of vehicles and pedestrians in the workplace, including the deployment of a trained banksman to guide reversing vehicles when necessary," said the spokesperson.

The spokesperson added that MOM is also investigating the incident.

Learning points to consider: 

1. *Clear visibility and spotters*: 

Ensure that drivers of reversing vehicles have clear visibility or are assisted by spotters to prevent accidents. This can be achieved through proper training, use of cameras or sensors, and designated spotters. 

2. *Segregation of pedestrians and vehicles*: 

Implement effective segregation measures to separate pedestrians and vehicles, reducing the risk of accidents. This can include designated walkways, barriers, and clear signage. 

3. *Reversing protocols and procedures*: 

Establish and enforce strict reversing protocols and procedures, including: - Mandatory spotters or guides - Use of reverse alarms or warning lights - Designated reversing areas or zones - Worker training on reversing hazards and procedures

Vehicular Safety in Workplaces

Four workplace fatalities and 19 major injuries1 resulting from vehicular-related accidents (excluding work-related traffic accidents)reported in 2023. Root cause identified include; Lack of a or inadequate Traffic Management Plan (TMP), non-compliance to the TMP, and negligence by the vehicle operator and/or co-workers are common causes of vehicular-related incidents in the workplace.

The Ministry of Manpower (MOM) will be conducting inspections targeting vehicular safety in industries such as transport & storage, marine, manufacturing, services, and construction in the upcoming months, 

Below are good workplace safety and health (WSH) practices commonly adopted by companies to prevent vehicular-related incidents. The WSH Council urges companies to establish a TMP and adopt these good practices to be well prepared for MOM’s upcoming inspections

With reference to the circular MOM/OSHD/2023-02 issued on 16 Feb 2023 (refer to https://www.mom.gov.sg/workplace-safety-and-health/wsh-circulars), the Ministry of Manpower (MOM) reminds Construction Companies to send WSH Coordinators who are appointed to work in their worksites to attend the WSH Coordinator Refresher Training every two years.

2 The WSH Act requires the Employer and the Principal to take reasonably practicable measures to ensure the safety and health of the workers. This includes providing these workers with adequate training for them to perform their work. The WSH Coordinator Refresher Training provides continuous training to build up

a WSH Coordinator’s competencies in assisting the occupier to manage workplace injury risks. This allows the WSH Coordinator to bridge WSH directives from the management to workers, and see to the implementation and compliance with WSH practices.

4. The refresher training will be conducted in two parts:

i) e-learning (to be completed within a week), which can be carried out anywhere, anytime, and completed by different sections, at the participant’s convenience using his/her mobile phones or any other internet-connected devices; AND

ii) a one day in-person training session, AFTER the participant has completed his/her e-learning.

5. The refresher training provides new information not covered in the WSH Coordinators’ Advanced Certificate in WSH course. Learners will be updated on the latest WSH developments, and key areas such as good WSH practices and effective management of contractors. There will be activities where they can apply their knowledge and skills to practical work scenarios with case studies relevant to construction as well as other different industries.

6. The refresher training fees is estimated to be about $100, at the company’s cost, and should not be deducted from the WSH Coordinator’s salary. You may contact either training provider, as listed below, to sign up your WSH Coordinator/s for the refresher training and register via the registration QR code. The training provider will assist with the setting up of email address account, if required, for any WSH Coordinator who does not have an email address account. The email address is necessary and required for the WSH Coordinator to access the e-learning.

7. To access the FAQs on the programme, you may scan the QR code below:

WSH Circular Safe Use Storage Racks

 WSH Circular Safe Use of Storage Racks

FACTORIES WITH WAREHOUSE STORAGE

Occupiers and employers engaged in warehouse and storage operations are reminded to take all reasonably practicable measures to ensure that the storage racks at your workplace are safe for use. You may refer to Annex A for guidance on some of the relevant WSH requirements. 

Step 1. Check your existing storage racks to ensure that they are designed for the intended storage load and have been properly installed.

Step 2. Perform a risk assessment on the use of storage racks.

Step 3. Establish a maintenance regime for the storage racks.

Annex A - Relevant WSH Requirements for Safe Use of Storage Racks

The following is a non-comprehensive list of relevant WSH requirements.

1) Design Consideration

The design of storage racks must allow for safe use and maintenance. The following should be considered in the design of storage racks:

a) Storage racks must be structurally stable and designed with the intended use in mind (e.g. weight, volume, shape, dimensions, environment to be used in etc.).

b) The safe working load of the storage racks should be prominently displayed. In particular, if the storage racks are stacked, the lower racks must be designed to take into account of the weight of the upper racks and their corresponding goods.

c) There should be safe means of access to the goods being stored, including proper work-at-heights measures.

d) The physical environment where the storage racks are to be used should be considered. For example, racks that are placed in areas where there is vehicular moment (e.g. forklifts, reach trucks etc) should be designed to withstand impact from possible collisions. In a cold room environment, temperature swings may require special considerations for corrosion protection due to moisture and other effects on the structural integrity of storage racks.

e) A re-assessment of the storage rack’s design should be carried before any change of use, including a change in the nature of goods to be stored.

2) Use of Storage Racks

The following measures are to be taken when using storage racks:

a) Use of storage racks should be carried out in accordance with the manufacturer’s instructions.

b) Conduct a risk assessment for the use of the storage racks.

c) Establish safe work procedures for work activities involving storage racks. The procedures should include confirming that the combined weight of the intended goods to be stored does not exceed the safe working load of the racks. In particular, if the racks are stacked, the bottom racks must have sufficient loading capacity to hold the racks and goods stored above.

d) Ensure that warehouse personnel made aware of the safe working loads and are trained on the safe work procedures for stacking and/or storage of goods.

3) Maintenance of Storage Racks

The following measures are to be taken when maintaining storage racks:

a) Maintenance of the storage racks should be carried out in accordance with the manufacturer’s instruction.

b) Storage racks and accompanying accessories (including pallets) should be regularly inspected to ensure their structural integrity (for example, no signs of damage or corrosion). Any defective part must be repaired or replaced before use.

Joint Circular on Nail Salon Safety

 Protecting Employees’ and Customers’ Health from Chemicals in Nail Salons

This circular provides guidance to nail salons on measures that can protect employees’ and customers’ health by minimising exposure to harmful chemicals.

Nail care products such as nail polishes, fingernail glues, and nail polish removers contain chemicals, some of which can be harmful to the health of nail salon employees and customers1. These products are regulated as cosmetic products under the Health Products

Act and must meet safety requirements specified in Act, as well as the Health Products (Cosmetic Products – ASEAN Cosmetic Directive) Regulations. To assist nail salons with

compliance, the safety requirements are set out in this Circular.

Use products that comply with safety requirements

a. Check that nail care products have been notified with the Health Sciences Authority (HSA), by checking HSA’s infosearch. Ensure that nail care products used do not contain prohibited chemicals and that restricted chemicals are used within the specified conditions

of use by referring to the Third Schedule of the cosmetic products regulation. For example:

▪ Formaldehyde is not allowed to be added as an ingredient into all cosmetic products, including nail care products.

▪ Toluene is only permitted in nail care products up to a maximum

concentration of 25%.

o A cosmetic product containing prohibited chemicals or using restricted chemicals not within the specified conditions of use would be considered an unwholesome health product. A person who manufactures, imports, or supplies an unwholesome

A person who manufactures, imports, or supplies an unwholesome health product is liable to a fine of up to $50,000 and/or imprisonment up to 2 years.

If the product cannot be found on HSA’s infosearch, inform your nail care product supplier to submit a notification via HSA’s website. A person who supplies an un-notified cosmetic product is liable to a fine of up to $20,000 and/or imprisonment up to 12 months.

b. Ensure that nail care products used comply with labelling requirements, including listing all ingredients on the product labels.

o Inform your nail care product supplier to add a warning label of “Contains formaldehyde”, if their products contain permitted preservatives that can release formaldehyde2 exceeding 0.05%.

o A person who supplies a cosmetic product that does not comply with this labelling requirement is liable to a fine of up to $50,000 and/or imprisonment up to 2 years.

Choose safer products

c. Minimise chemical exposures by using products that are water-based or have a low content of volatile organic compounds (VOCs, such as formaldehyde, toluene, xylene).

Follow safe work practices

d. Communicate to employees the hazards of handling nail care products, and encourage them to adopt safe work practices such as:

o Good housekeeping, e.g. keep dispenser bottles closed when not in use, clean up spills immediately.

o When applying nail care products, use only the amount needed to minimise chemical emissions into the air.

o Dispose of waste containing nail care products in sealed bags or keep wastebins covered. Empty wastebins frequently.

o Where needed, use personal protective equipment (PPE) such as gloves and goggles to protect employees’ skin and eyes. Nail salon operators should refer to the information in product labels or information sheets and provide the appropriate PPEs where necessary.

Ensure good ventilation and indoor air quality

e. Ventilate the space within the nail salon. If the salon has an air-conditioning and mechanical ventilation system that provides

outdoor air, check that the system is in good working condition.

o In air-conditioned spaces with no outdoor air supply, consider opening doors and windows to facilitate air exchange when feasible. Additionally, consider using local exhaust systems such as portable ventilation machines or ventilated tables to minimise exposure to VOCs emitted.

f. To maintain good indoor air quality for the wellbeing of customers and employees, operators may also refer to the advisory limits of specific VOCs in the Singapore Standard SS554: Code Of Practice For Indoor Air Quality For Air-Conditioned Buildings.

Note 1 Exposure to chemicals in nail care products may occur via three routes: (1) inhaling volatile organic compounds

(VOCs such as formaldehyde, toluene, xylene) emitted from the products; (2) getting the products on skin or in eyes; or (3) ingesting the products that have come in contact with food or drinks. For example, exposure to formaldehyde can be through inhalation and this may lead to respiratory irritations, allergic reactions, and even

long-term serious health effects such as cancer

Phasing Out Fire Protection Foams

 PHASING OUT OF FIRE-FIGHTING FOAMS CONTAINING PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) CHEMICALS LISTED UNDER THE STOCKHOLM CONVENTION

Singapore is a Party to the Stockholm Convention, which aims to eliminate and/or restrict production and use of Persistent Organic Pollutants (POPs). Three Per- and Polyfluoroalkyl Substances (PFAS) chemicals are listed in the Stockholm Convention, with time-limited exemptions for usage in fire-fighting foams for Perfluorooctanoic acid (PFOA), its salts and related compounds and Perfluorooctane sulfonic acid (PFOS), its salts and related compounds. The exemptions under the Stockholm Convention will expire in Dec 2025. There is no exemption under the Stockholm

Convention for usage of Perfluorohexane sulfonic acid (PFHxS), its salts and related compounds in fire-fighting foams.

2 Therefore, with effect from 1 Jan 2026, Singapore will phase out the import and use of firefighting foams containing PFOA and PFOS, including their salts and related compounds.

WSH Guidelines Construction Procurement

 Workplace Safety and Health Guidelines on Procurement in the Construction Industry

What is WSH Guidelines 

WSH Guidelines showcased workplace safety and health best practices and WSH program for controlling workplace hazards and improving occupational health for various industry and program 

Check out the free WSH Guidelines on Procurement in the Construction industry to improve your organization WSH practices. For the latest WSH Guidelines update, refer to Singapore Workplace Safety and Health Council Website.

Developers can demonstrate strong WSH ownership by incorporating WSH principles into their procurement process. Eliminating tenderers who may struggle to cope with WSH risks improves WSH performance across the construction industry.

 

1.1 Role of Procurement in Strengthening WSH Outcomes

Developers, as the apex pay masters in the construction industry value chain, exert strong influence over strengthening WSH practices and culture across main and sub-contractors

through their procurement contracts.

Principle 2 of the Code of Practice on Chief Executives’ and Board of Directors’ WSH Duties (ACOP) states that company directors can demonstrate leadership in improving WSH performance and management by continuously building a strong WSH culture, setting the tone, and demonstrating visible leadership in embodying and communicating highly effective WSH standards.

One of the ways CEOs and Board directors can adopt this principle is by setting and demanding effective WSH standards and performance from their vendors and partners. 

These guidelines give details and examples on how construction companies, particularly developers, should design their procurement practices in support of Principle 2 of the ACOP

New Lorry Crane Stability System

 New Lorry Crane Stability Control System Requirement Effective 2025

SINGAPORE: Newly registered lorry cranes shall be installed with a stability control system effective from 2025 onward, to eliminate the risk of the heavy vehicles toppling over.

According to the Ministry of Manpower, over the past decade, 63 per cent of all dangerous occurrences involving lorry cranes could have been prevented with a stability control system,

There were a total of 14 dangerous occurrences involving lorry cranes between 2020 and 2024, resulting in two deaths.

Lorry cranes are used to load and unload material and equipment, and are frequently used near public areas, said MOM.

"If the crane topples, it can have a severe impact on workers and it can potentially even impact and affect members of the public," 

Lorry cranes have stabilisers in the form of outriggers that extend from the vehicle chassis

But in some environments where space is constrained, the stabilisers cannot extend fully. This can compromise the safety of lifting operations, said MOM.

A stability control system detects the deployment and extension of each stabiliser, and also takes into account the load being carried by the lorry crane.

The system then calculates and restricts crane manoeuvres within a safe lifting zone.

WSH Circular Airconditioning Condenser Installation

MOM & BCA Joint Circular on Safety Considerations in Installation and Maintenance of Airconditioning Condensing Units and their Structural-Supporting System

1. The Ministry of Manpower (MOM) and the Building and Construction Authority (BCA) are jointly issuing this circular to remind all stakeholders responsible for the installation and maintenance of air-conditioning condensing units ("air-con units") and their structural supporting systems.

2. Working on externally mounted air-con units are high-risk work at height (“WAH”) activities. In August 2023, an air-con technician tragically fell to his death while maintaining an air-con unit mounted on the exterior of a building. In February 2024, another air-con technician also lost his balance when the structural supporting system of the air-con unit he was working on gave way, narrowly escaping a fatal fall. 

3. However, incidents of Fall from Height (“FFH”) can be easily prevented with the establishment and implementation of safety measures. This circular emphasises the duty of stakeholders to take all reasonably practicable measures to ensure the safety of workers at work and the safety of members of the public who may be affected by the work.

Pre-requisites

4. Only Trained Air-con Unit Installers (“TAIs”) who have successfully completed the training course on the installation of a structural supporting system to support an air-con unit required by BCA can install air-con unit on the exterior of any building. TAIs must comply with requirements in Part IVA of the Building Control Regulations 2003 (“BC Regs”) and ensure that the installed structural support systems (existing or replacement) comply with specifications listed under Part I, II, III or IV of the Seventh Schedule of the BC Regs. For Housing and Development Board (“HDB”) properties, the specifications and general conditions found in HDB’s InfoWEB must also be complied with.

Site Preparation and Risk Assessment

5. Before air-con servicing workers or TAIs commence any work, perform a site specific risk assessment to identify hazards, evaluate risks, and determine appropriate risk control measures. Implement these measures and ensure that all workers are briefed and familiar with them. Measures must be adopted to ensure that the structural supporting systems would not be overloaded during work.

6. Air-con servicing workers must look out for obvious signs of deterioration (such as loosened bolts and nuts, badly corroded brackets and misalignment or dislodgement) on the structural supporting systems. If any of such signs is observed, TAIs must be engaged to inspect and rectify or replace the structural supporting systems before air-con servicing work can be carried out. Please refer to Appendix 2 for examples of deterioration.

7. Establish cordons around all work zones and affected areas at ground level to restrict access to individuals not involved in the works. This includes areas where objects have the potential to fall and cause injury. For examples of area cordoning, please refer to Appendix 3.

Fall Prevention Management

8. Whenever possible, do not carry out WAH activities on top of the air-con units and/or its structural supporting systems.

9. When WAH is unavoidable, it is essential to consider fall arrest measures for workers. Ensure that secure anchor devices are installed. For examples of fall arrest measures, please refer to the information provided in Appendix 4.

10. In addition to having the necessary physical controls, it is crucial to ensure that workers carrying out WAH activities receive adequate training and supervision:

a) Deploy only trained workers who have received trade-specific training and have successfully completed the relevant WAH courses acceptable to MOM. You may refer to Appendix 5 for information on accredited WSH courses and training providers.

b) Appoint a competent person to provide thorough supervision for the workers, ensuring they are not exposed to hazards and that all necessary precautions are taken in situations where there is a risk of falling; and

c) Ensure adequate supervision especially when workers are new, inexperienced, and unfamiliar with the working environment

Post-installation

11. TAIs must submit a report of the installation works no later than 14 days after completion to the Commissioner of Building Control:

a) For private properties, submit Form AC-01 to BCA; or

b) For HDB properties, submit Form AC-02 to HDB via e-feedback form at

www.hdb.gov.sg/efeedback .

The forementioned forms with submission instructions can be retrieved from BCA’s webpage on air-con units safety indicated in Appendix 5.

12. Please refer to informative references in Appendix 5. Should you need further information, please contact:

a) MOM at 6438 5122 for information on workplace safety and health; or

b) BCA at 1800 3425 222 for issues relating to structural supporting systems of air-con units.
