Question 1

What respiratory protection is required when workers are exposed to dust on Singapore construction sites?

Accepted Answer

Appropriate dust masks or respirators rated for the type and concentration of dust present

Answer

Workers exposed to construction dust (silica, cement, wood) must use appropriate respiratory protection rated for the specific contaminant. N95 masks are minimum for nuisance dust, while specific respirators are needed for silica and chemical exposures.

Question 2

What are the employer's obligations regarding PPE maintenance on Singapore construction sites?

Accepted Answer

Employers must ensure PPE is regularly inspected, cleaned, maintained, and replaced when necessary

Answer

Employers must implement a PPE maintenance programme including regular inspection, proper cleaning and storage, timely replacement of worn or damaged items, and record-keeping of PPE issuance.

Question 3

When are safety goggles or eye protection required on Singapore construction sites?

Accepted Answer

During any activity that poses a risk to the eyes, including cutting, grinding, drilling, chipping, and chemical handling

Answer

Eye protection is required during any activity that could generate flying particles, sparks, dust, or chemical splashes. This includes grinding, cutting, drilling, welding, and handling hazardous chemicals.

Question 4

What type of gloves should be used for handling cement on Singapore construction sites?

Accepted Answer

Chemical-resistant gloves (e.g., nitrile or rubber) that protect against the alkaline nature of wet cement

Answer

Wet cement is highly alkaline (pH 12-13) and can cause chemical burns and dermatitis. Chemical-resistant gloves made of nitrile or rubber are required to protect against skin contact.

Question 5

What is the correct way to store PPE on a Singapore construction site?

Accepted Answer

Store in a clean, dry, designated area away from direct sunlight, chemicals, and extreme temperatures

Answer

PPE must be stored properly to maintain its protective properties. UV exposure degrades helmets, moisture damages respiratory filters, and chemicals can weaken glove materials.
