Heat Stress Management

Managing heat stress as Singapore gets warmer

2023 was Singapore’s fourth-hottest year1, with a sweltering high of 37°C in May 2023. In the Third National Climate Change Study2, Singapore’s climate is projected to become warmer, with very hot days becoming more frequent by the end of this century.

The rise in temperatures put workers, especially those working outdoors, at an increased risk of heat stress. For work to continue in a safe manner, employers will need to do more to protect outdoor workers.

In the upcoming months, the Ministry of Manpower will be conducting workplace inspections in the construction, shipyards and process industries, to check the effectiveness of heat stress measures for outdoor work.

Implementing an Effective Heat Stress Management Programme

To protect workers and increase resilience to rising temperatures, employers are required to implement enhanced heat stress measures for outdoor work3. Workplaces are to ensure effective implementation of the following protective measures: 

Figure 2: Example of a portable WBGT monitor.

Other Heat Stress Protective Measures

• Adequate ventilation: Cool rest and work areas with fans or air coolers.

• Light-coloured clothes: Provide breathable, loose-fitting and light-coloured clothing for outdoor workers to wear.

• Work rescheduling: Carry out physical work during cooler parts of the day.

• Mechanical assistance: Reduce physical exertion with mechanical aids, like manual handling equipment and powered tools.

Early recognition of signs and symptoms: Implement a buddy system to aid early recognition of heat-related signs, symptoms and illnesses (e.g. fainting spells, disoriented behaviours) for prompt interventions.

Heat-related illnesses may affect workplace safety or lead to a workplace accident. The WSH Council urges employers to partner workers and manage heat stress effectively, for a safe and healthy workplace.

2 Ministry of Sustainability and the Environment’s Joint Media Release on Singapore’s Third National Climate Change Study (5 Jan 2024).

3 Ministry of Manpower’s Press Release on Enhanced Measures to Reduce Heat Stress for Outdoor Workers (Oct 2023).

4 Workers who are vulnerable to heat stress includes those who are newly assigned to outdoor work; unacclimatised to working in hot environments (e.g. new or returning from countries with a cold climate); returning from long leave of more than a week; recovering from prolonged illness; and have personal factors (e.g. chronic diseases, medication use, history of heat injury or pregnant).

SAFE STORAGE AND HANDLING OF FLAMMABLE SUBSTANCES

Background

1 On 7 March 2023, an explosion followed by a fire occurred in a room that served a motor workshop, causing parts of the building’s walls to collapse. Investigations revealed that the fire was likely due to the ignition of accumulated flammable vapours from a waste oil collection tank within the room.

2 Days later, another fire incident occurred on 13 March 2023. The fire engulfed an industrial building and caused minor injuries to two workers. Investigations indicated that uncontrolled electrostatic discharge had ignited flammable vapours generated during a dispensing process. Both incidents were dangerous occurrences that could have caused fatalities.

Storage of Flammable Liquids

3 To prevent similar fires, occupiers shall ensure that flammable liquids are kept away from all sources of heat or ignition such as hot surfaces, open flames and even equipment that are not suitably enclosed to prevent internal sparks from igniting any flammables in the surrounding (see Annex A for examples); and stored in containers made of non-combustible materials of sound integrity, labelled, and covered to prevent accidental spills and accumulation of flammable vapours in the workplace (see Annex B for examples).

4 Effective controls shall also be implemented to mitigate electrostatic discharge. This includes the installation of grounding and bonding systems as well as the conduct of annual continuity tests, both by competent persons1

 1 Such as licensed electrical workers (LEWs).

Management of Flammable Wastes

5 Flammable liquid wastes, such as petrol collected from vehicle repair/servicing activities, can cause fires and explosions. Motor workshop operators, for example, shall identify and ensure that liquid wastes containing such flammable liquids are stored separately from non-flammable liquid wastes, before collection by licenced toxic industrial waste collectors (TIWCs). Mixtures of flammable liquid waste and liquids shall be treated as flammable liquids unless they have been laboratory-tested as non-flammable and may therefore be subjected to licensing requirements by the SCDF

6 TIWCs licensed by National Environment Agency shall be engaged to dispose flammable liquid waste or mixtures. A list of TIWCs can be found here or via the QR code.

Other Control Measures to Prevent Fires and Explosions

7 There are other control measures for flammable substances that are required to prevent fires and explosions in the workplace.

Annex A – Store Flammables away from Heat and Ignition Sources

The lack of an effective bonding and grounding system can lead to unintended discharge of accumulated electrostatic charges during the transfer of flammable liquids.

Unsealed containers holding flammable liquids are capable of emitting flammable vapours into the work environment

When flammable vapours meet heat or ignition sources, fires and explosions can occur. Some heat or ignition sources include:

• Open flames, such as welding, candles;

• Sparks and excessive heat from machinery moving parts;

• Overloaded power sockets, exposed electrical wires and circuitry.

Prevent Falls from Open Sides Guide

Open sides without proper barricades and lack of safe access are common safety lapses leading to fall-from-height incidents, where workers have suffered serious injuries or even lost their lives.

In the upcoming months, the Ministry of Manpower will be conducting inspections targeting work-at-height infringements in the construction, marine, and transport and storage industries.

Protect your workers from falling over open sides by including the following measures adopted by many companies, into your fall prevention plan: 

• Conduct a toolbox briefing before starting work. Alert workers to onsite risks and remind them how they can work safely at heights. New workers are to complete work-at-height training and a site orientation before being deployed to work at height.
• Close off all open sides. Install guardrails and/or barricades along the perimeter of open sides. The edge protection must be able to withstand a weight of 100kg applied in any direction. Refer to Figure 1 for the required dimensions for edge protection.

Figure 1:  Required dimensions for edge protection. 

• Install a travel-restraint system. This restricts the movement of workers and keeps them at a safe distance from any open sides if edge protection is not feasible.

• Equip workers with fall-arrest equipment. If a travel restraint system is not feasible, each worker must wear a full-body harness with connecting lanyards OR a self-retracting lifeline.

• Secure anchor points. Identify and/or provide suitable anchor points for each worker to hook their lanyards on to while they work at height. Never deploy workers to work at height at sites where there are no suitable anchor points. Refer to Figures 2, 3 and 4 on the various types of secure anchor points.

Figure 2:  Bolt anchor point. 

Figure 3:  Horizontal lifeline

Figure 4:  Anchor sling around a structural element.

• Ensure 100% tie-off. Provide workers with a twin-tailed double lanyard (refer to Figure 5) and train workers how to use the double lanyard such that they are hooked to at least one anchor point or lifeline at any time.

Figure 5: Twin-tailed double lanyard. 

• Maintain good workplace housekeeping. Ensure work areas and designated walkways are clear of obstructions. Store loose tools and materials away from open sides as these can fall and strike persons below, or cause workers working near an open side to trip and fall.

Figure 6: Keep area near open sides clear. 

• Implement a permit-to-work (PTW) system. Implement a PTW for work-at-height activities where a worker could fall more than three metres. This ensures onsite checks are carried out to confirm risk controls are in place and effective before the work is authorised to proceed.

Control of Chemicals and Mercury Added Products

The National Environment Agency (NEA) is seeking feedback on the proposed control of 2 groups of chemicals and 9 mercury-added products as hazardous substances (HS) under the Second Schedule of the Environmental Protection and Management Act (EPMA) and the Schedule of the (EPM (HS) Regulations)1. This consultation will last 4 weeks from 18 Jan 2024 to 15 Feb 2024.

Background

2 Singapore is party to the Stockholm Convention (SC), which aims to eliminate and restrict the production and use of persistent organic pollutants, and the Minamata Convention (MC), which aims to protect human health and the environment from man-made emissions and releases of mercury and mercury compounds. NEA, as the Competent Authority for the SC and the MC, controls chemicals listed under the respective Conventions to ensure that the international obligations are complied with. 

Proposed Control on 2 Groups of Chemicals

3 The following 2 groups of chemicals have several industrial usages and have been assessed by the Persistent Organic Pollutants Review Committee (POPRC) of SC to be highly toxic, persistent and can bio-accumulate to cause long lasting harmful effect in the environment:

a. Medium chain chlorinated paraffins (MCCPs) i.e. Chlorinated paraffins with carbon chain lengths in the range C14–17 and chlorination levels at or exceeding 45 per cent chlorine by weight

b. Long-chain perfluorocarboxylic acids (LC-PFCAs) with carbon lengths of 9 to 21, their salts and related compounds

4 In anticipation that POPRC is likely to recommend for their adoption into Annex A of the SC for elimination at the 12th Conference of Parties (COP) held in 2025. NEA intends to pre-emptively impose regulatory controls over the import, export, manufacture, offer for sale, transport, purchase, storage and/or use of these chemicals to ensure the environmentally sound management of these chemicals. Prior to the ban of LC-PFCAs and MCCPs under SC, companies will be allowed to import, export, manufacture or sell these chemicals with a valid HS Licence from NEA, or store or use these chemicals with a valid HS Permit from NEA. The POPRC is also conducting further assessment on the usage of MCCPs and LC-PFCAs and may recommend limited exemptions for certain uses that do not have viable alternatives.  

Proposed Control on 9 Mercury-Added Products

5 In addition, Parties to the MC have agreed to list 9 mercury-added products under Annex A of the MC, which are listed below, for them to be phased out by end 2024.  These mercury-added products can release mercury, which is highly toxic, persistent, and can also bio-accumulate to cause long lasting harmful effects to the environment. As such, NEA intends to control these 9 mercury-added products as HS and to phase them out by end 2024.  Therefore, the manufacture, import and export of the 9 mercury-added products will not be allowed from 1 Jan 2025.

a. Compact fluorescent lamps with an integrated ballast (CFL.i) for general lighting purposes that are ≤ 30 watts with a mercury content not exceeding 5 mg per lamp burner 

b. Cold cathode fluorescent lamps and external electrode fluorescent lamps of all lengths for electronic displays

c. Strain gauges to be used in plethysmographs

d. The following electrical and electronic measuring devices except those installed in large-scale equipment or those used for high precision measurement, where no suitable mercury free alternative is available:

•Melt pressure transducers, melt pressure transmitters and melt pressure sensors

e. Mercury vacuum pumps

f. Tyre balancers and wheel weights

g. Photographic film and paper

h. Propellant for satellites and spacecraft i. Very high accuracy capacitance and loss measurement bridges and high frequency radio frequency switches and relays in monitoring and control instruments with a maximum mercury content of 20 mg per bridge switch or relay [except those used for research and development purposes]

6 NEA intends to gazette the regulatory changes by Jun 2024. This would be followed by a six-month transitional period before the changes come into force by Jan 2025.

Request for Feedback

7 This proposal is released for the purpose of consultation. Comments received during the consultation exercise will be reviewed and may be considered in developing the final measures. Parties wishing to provide feedback may do so at https://form.gov.sg/65a634b2f2138c00121a161f or send an email to Primus_ONG@nea.gov.sg and Nikki_LEE@nea.gov.sg by 15 Feb 2024.

8 In order to ensure that the consultation is productive and focused, respondents are requested to adhere to the following guidelines when providing their feedback:

a. Identify yourself as well as the organisation you represent (if any) so that NEA may follow up with you to clarify on any issue where necessary.

b. Be clear and concise in your comments.

c. Focus your comments on the proposal and how it can be improved.

d. Substantiate your points with illustrations, examples, data or alternative suggestions.

Solar Panel Installation Safety

 Good WSH Practice In Protecting Solar Panel Installers from Electrocution

The Singapore Green Plan 2030 aims to deploy enough solar energy to power 350,000 households annually by 2030. To support this goal, more solar panels will be installed and workers must be kept safe while doing such works. Along with falling from height risks, electrocution is a major workplace safety and health (WSH) concern during solar panel installation and maintenance.

There are several good practices companies can adopt to protect workers from solar panel-related electrocution risks:

Install solar panels as per design, e.g. a photovoltaic (PV) single line diagram.

Figure 1: Example of a PV single line diagram.

Place and secure an opaque cover over each solar panel to prevent the panel being energised while not plugged in.

Cover all exposed electrical parts such as cables and connectors with an insulated cap to isolate the wire ends/terminals. Workers have been electrocuted even when solar panels were not plugged in, due to exposed cables.

Figure 2: Example of a connector with insulated end cap.

Secure loose cables and connector ends away from the conducting medium (such as metal or water), e.g. by securing them under the solar panel

Figure 3: Example of cables secured under a solar panel.

Provide workers with electrical-resistant personal protective equipment, such as arc-rated protective clothing, insulated gloves and rubber-soled shoes.

Report any PV system breakdown or abnormality, or damaged cables/connector to the licensed electrical worker immediately.

Safe Road Transportation of Workers

Following recent enforcement operation conducted by the Ministry of Manpower (MOM) on Safe Transportation of Workers on Lorries to ensure compliance with the revised Workplace Safety and Health (General Provision) Regulations for transporting workers on lorry decks, some common unsafe work practices were identified.

Here are some of the unsafe work practices

Unsafe Work Practice 1

Equipment and materials on lorry’s rear deck were not secured, posing a safety hazard to workers on the rear deck. No proper foothold was provided for workers alighting and boarding the lorry’s rear deck.

Recommendation

Provide proper and secure footholds so that workers can enter and exit the lorry deck safely.

Unsafe Work Practice 2

No vehicle buddy was found seated in the cabin of the lorry next to the driver

Recommendation

A vehicle buddy should be seated next to the driver at all times to ensure that the driver is alert while transporting workers

Unsafe Work Practice 3

Goods and equipment were not properly secured.

Recommendation

Transported loads must be properly secured to prevent movement, especially when the vehicle is braking, to avoid injuring workers in the rear deck.

MOM urge companies to comply with the safety regulations to ensure the safe transportation of workers on lorries. Details of the revised Workplace Safety and Health (General Provision) Regulations for transporting workers on lorry decks can be found at www.go.gov.sg/wsh-safetransport
