Review these sample questions before starting the practice test.
Q1: Where does PPE sit in the hierarchy of controls?
- A. At the top β most effective
- B. Second after elimination
- C. In the middle
- D. At the bottom β least effective, last resort β
PPE is at the bottom of the hierarchy of controls. It should be used as a last resort when higher-level controls cannot adequately reduce the risk.
Q2: What standard must safety helmets (hard hats) comply with in Australia?
- A. AS 1337
- B. AS 2210
- C. AS/NZS 1801 β
- D. AS 1319
Safety helmets (hard hats) must comply with AS/NZS 1801 for protective helmets. This standard ensures they meet impact and penetration resistance requirements.
Q3: When must a hard hat be replaced?
- A. Every 6 months regardless of condition
- B. After a significant impact, if cracked or damaged, or as per manufacturer guidelines β
- C. Only when the colour fades
- D. Only when a supervisor tells you
Hard hats must be replaced after any significant impact, if cracked, deformed, or damaged, or as per the manufacturer's recommended service life (typically 3-5 years).
Q4: What type of safety footwear is required on most construction sites?
- A. Regular sneakers
- B. Steel-capped (or composite-toe) safety boots complying with AS/NZS 2210.3 β
- C. Thongs or sandals with good grip
- D. Any closed-toe shoe
Construction sites require safety boots with toe protection (steel cap or composite) complying with AS/NZS 2210.3 to protect against crush injuries and puncture.
Q5: What is the purpose of high-visibility (hi-vis) clothing on a construction site?
- A. To identify the company you work for
- B. It is purely decorative
- C. To keep workers warm
- D. To make workers clearly visible to equipment operators and vehicle drivers β
Hi-vis clothing makes workers clearly visible, reducing the risk of being struck by vehicles or mobile plant, especially in low-light conditions.
Q6: When should hearing protection be worn on a construction site?
- A. Only during lunch breaks
- B. Only if you have a pre-existing hearing condition
- C. Whenever noise levels exceed 85 dB(A) or as indicated by signage β
- D. Only when using power tools indoors
Hearing protection must be worn when noise levels exceed 85 dB(A) over an 8-hour time-weighted average, or when mandatory signage indicates its requirement.
Q7: What is the difference between Class 1 and Class 2 earmuffs?
- A. Class 1 is for construction; Class 2 is for offices
- B. Class 1 provides lower attenuation; Class 2 provides higher attenuation β
- C. They are identical
- D. Class 1 is for rain; Class 2 is for dust
Hearing protectors are rated by class (1-5 under AS/NZS 1270). Higher class numbers provide greater noise attenuation. Selection depends on the noise level present.
Q8: Which Australian Standard covers eye and face protection?
- A. AS/NZS 1801
- B. AS/NZS 4602
- C. AS/NZS 2210.3
- D. AS/NZS 1337.1 β
