Question 1

What are the main categories of workplace hazards recognised in Singapore's WSH framework?

Accepted Answer

Physical, chemical, biological, ergonomic, and psychosocial hazards

Answer

Singapore's WSH framework recognises five main categories of hazards: physical (noise, vibration, machinery), chemical (toxic substances), biological (pathogens), ergonomic (repetitive strain), and psychosocial (stress, violence).

Question 2

What is the Permissible Exposure Limit (PEL) for chemical hazards in Singapore workplaces?

Accepted Answer

The maximum airborne concentration of a substance a worker may be exposed to over a specified time, set by MOM regulations

Answer

PELs are regulatory limits on the concentration of chemical substances in workplace air. Singapore's WSH (General Provisions) Regulations specify PELs to protect workers from harmful exposures.

Question 3

What is a Safety Data Sheet (SDS) and when is it required in a Singapore workplace?

Accepted Answer

A document providing information about hazardous chemicals, required whenever such chemicals are used, stored, or handled in the workplace

Answer

An SDS (formerly MSDS) provides detailed information about a chemical substance including hazards, handling precautions, first aid, and disposal. Employers must ensure SDSs are available for all hazardous chemicals at the workplace.

Question 4

Under Singapore regulations, what is a 'confined space' and why is it dangerous?

Accepted Answer

An enclosed or partially enclosed space not designed for continuous occupancy, with hazards like poor ventilation, toxic gases, or engulfment risk

Answer

Confined spaces (e.g., tanks, manholes, silos) pose special dangers including oxygen deficiency, toxic atmosphere, engulfment, and restricted entry/exit. Singapore's WSH (Confined Spaces) Regulations impose strict controls on entry.

Question 5

What is the maximum permissible noise exposure level for an 8-hour workday in Singapore?

Accepted Answer

85 dB(A)

Answer

Under Singapore's WSH (Noise) Regulations, the permissible exposure limit for noise is 85 dB(A) over an 8-hour time-weighted average. Employers must implement noise control measures and hearing conservation programmes above this level.
