Safe Pass Hazard Identification on Sites 3 — Questions and Answers
Question 1: What is a trip hazard commonly found on construction sites?
- Trailing cables and hoses across walkways (Correct answer)
- A completed staircase with handrails
- A properly stored toolbox
- A clearly marked emergency exit
Correct answer: Trailing cables and hoses across walkways
Trailing cables, hoses, and other materials left across walkways are common trip hazards on construction sites that can cause falls.
Question 2: What hazard is created by unprotected openings in floors?
- Fall hazard — workers could fall through to a lower level (Correct answer)
- Chemical exposure
- Noise pollution
- Biological contamination
Correct answer: Fall hazard — workers could fall through to a lower level
Unprotected floor openings are a serious fall hazard that could result in workers falling to a lower level, potentially causing severe injury or death.
Question 3: What type of hazard does asbestos represent on a construction site?
- Chemical hazard causing respiratory disease (Correct answer)
- Electrical hazard
- Ergonomic hazard
- Noise hazard
Correct answer: Chemical hazard causing respiratory disease
Asbestos is a chemical/material hazard that when disturbed releases fibres which, if inhaled, can cause serious respiratory diseases including mesothelioma and asbestosis.
Question 4: What is the hierarchy of risk control measures?
- Eliminate, Substitute, Engineering controls, Administrative controls, PPE (Correct answer)
- PPE first, then everything else
- Administrative controls only
- Substitute and PPE only
Correct answer: Eliminate, Substitute, Engineering controls, Administrative controls, PPE
The hierarchy of controls prioritises elimination first, then substitution, engineering controls, administrative controls, and PPE as the last resort.
Question 5: What hazard does working near overhead power lines present?
- Electrocution — electricity can arc through the air (Correct answer)
- Chemical burns
- Noise exposure
- Manual handling injury
Correct answer: Electrocution — electricity can arc through the air
Overhead power lines carry high voltage electricity that can arc through the air to equipment or persons who come too close, causing electrocution.
Question 6: What is a confined space hazard on a construction site?
- An enclosed area with potential for oxygen depletion, toxic atmosphere, or entrapment (Correct answer)
- Any small room
- A standard office
- A wide open trench
Correct answer: An enclosed area with potential for oxygen depletion, toxic atmosphere, or entrapment
A confined space is an enclosed or partially enclosed area not designed for continuous occupancy, which may have a dangerous atmosphere, risk of engulfment, or limited entry/exit.
