Safety Trained Supervisor Hazard Identification and Awareness Questions and Answers 1 — Questions and Answers
Question 1: A supervisor is conducting a Job Hazard Analysis (JHA) for a routine task involving multiple steps. What is the PRIMARY goal of the first step in this process?
- To determine the appropriate personal protective equipment (PPE).
- To identify the potential hazards associated with each step.
- To break the job down into a sequence of distinct steps. (Correct answer)
- To implement control measures for the identified risks.
Correct answer: To break the job down into a sequence of distinct steps.
The first step of a Job Hazard Analysis (JHA), also known as a Job Safety Analysis (JSA), is to break the job into a sequence of steps. This provides a foundation for the subsequent steps, which are to identify potential hazards and then determine preventive measures for those hazards.
Question 2: Which of the following is considered the MOST effective type of hazard control measure according to the hierarchy of controls?
- Implementing a new administrative procedure.
- Requiring the use of personal protective equipment (PPE).
- Physically removing the source of the hazard. (Correct answer)
- Installing machine guards to isolate workers from the hazard.
Correct answer: Physically removing the source of the hazard.
The hierarchy of controls ranks hazard control methods from most to least effective. Elimination, which is physically removing the hazard, is the most effective measure. Engineering controls (like machine guards), administrative controls, and PPE are progressively less effective and should be considered when elimination is not feasible.
Question 3: A construction site supervisor notices a new, unevaluated chemical has been brought onsite by a subcontractor. Which of the following is the most appropriate initial action for the supervisor to take to identify the hazards associated with this chemical?
- Ask the subcontractor's employees if they have worked with it before.
- Observe the chemical's physical properties and look for warning labels.
- Assume it is hazardous and require full-body PPE for anyone nearby.
- Request and review the Safety Data Sheet (SDS) for the chemical. (Correct answer)
Correct answer: Request and review the Safety Data Sheet (SDS) for the chemical.
The Safety Data Sheet (SDS) is the primary source of detailed information about a hazardous chemical. It provides information on identification, hazards, composition, first-aid measures, and handling and storage, which is essential for proper hazard identification and awareness.
Question 4: A supervisor tracks the number of safety observations, near-miss reports, and safety training sessions completed each month. These metrics are examples of what type of safety performance indicators?
- Reactive Indicators
- Lagging Indicators
- Proactive Indicators (Correct answer)
- Incident Rate Indicators
Correct answer: Proactive Indicators
These are examples of proactive or leading indicators. Leading indicators are measures that are proactive in nature and track activities and conditions that can prevent incidents before they happen. Lagging indicators, in contrast, measure outcomes after an incident has occurred, such as injury rates or lost workdays.
Question 5: During a routine workplace inspection, a supervisor identifies an unguarded rotating shaft on a piece of machinery. This represents which category of hazard?
- Ergonomic Hazard
- Chemical Hazard
- Safety Hazard (Correct answer)
- Biological Hazard
Correct answer: Safety Hazard
An unguarded rotating shaft is a classic example of a safety hazard. Safety hazards are conditions that can cause immediate physical harm, such as cuts, fractures, or amputations. Other examples include spills, tripping hazards, and working from heights.
Question 6: To effectively identify ergonomic hazards in an office setting, a supervisor should focus on which of the following?
- The flammability of cleaning supplies.
- The frequency of fire drills.
- The adequacy of the emergency lighting.
- The design of workstations and repetitive tasks. (Correct answer)
Correct answer: The design of workstations and repetitive tasks.
Ergonomic hazards are related to the strain a work environment and work tasks place on the body. In an office setting, this would include improperly adjusted workstations, poor posture, and repetitive movements that can lead to musculoskeletal disorders.
