SAF Risk Assessment & Hazard Identification 3 — Questions and Answers
Question 1: Which hazard category includes slips, trips, and falls as well as struck-by and caught-in hazards?
- Chemical hazards
- Physical hazards (Correct answer)
- Biological hazards
- Ergonomic hazards
Correct answer: Physical hazards
Slips, trips, falls, struck-by, and caught-in incidents are classified as physical hazards because they involve energy transfers or mechanical contact.
Question 2: According to the hierarchy of controls, which control type is considered MOST effective?
- Personal protective equipment
- Administrative controls
- Engineering controls
- Elimination (Correct answer)
Correct answer: Elimination
Elimination — physically removing the hazard — is the most effective control because it removes the risk at the source.
Question 3: A Safety Data Sheet (SDS) Section 2 provides information on:
- Physical and chemical properties
- Hazard identification (Correct answer)
- First-aid measures
- Handling and storage
Correct answer: Hazard identification
SDS Section 2 is dedicated to hazard identification, including GHS classification, signal words, and hazard statements.
Question 4: What does the acronym 'ALARP' stand for in risk management?
- Actual Loss And Risk Prevention
- As Low As Reasonably Practicable (Correct answer)
- Assessed Level of Acceptable Risk Protocol
- Allocated Likelihood and Risk Parameter
Correct answer: As Low As Reasonably Practicable
ALARP means 'As Low As Reasonably Practicable,' indicating risk must be reduced until further reduction would be grossly disproportionate to the benefit.
Question 5: Which method involves systematically examining a process by asking 'What if?' questions to identify potential deviations and consequences?
- Fault Tree Analysis
- What-If Analysis (Correct answer)
- FMEA
- HAZOP
Correct answer: What-If Analysis
A What-If Analysis uses structured 'What if?' questions to brainstorm deviations from normal operations and their potential consequences.
Question 6: Ergonomic hazards in the workplace primarily contribute to which type of injury?
- Burns and thermal injuries
- Musculoskeletal disorders (Correct answer)
- Acute chemical poisoning
- Hearing loss
Correct answer: Musculoskeletal disorders
Ergonomic hazards — such as repetitive motion, awkward postures, and forceful exertion — are the leading cause of musculoskeletal disorders (MSDs).
Question 7: During a risk assessment, 'exposure' refers to:
- The severity of harm if a hazard is realized
- The frequency and duration of contact with a hazard (Correct answer)
- The number of workers in the facility
- The cost of implementing controls
Correct answer: The frequency and duration of contact with a hazard
Exposure is the frequency and duration with which workers come into contact with a hazard, which directly affects overall risk level.
