Question 1: Which of the following best describes the purpose of a Job Hazard Analysis (JHA)?
- To document employee disciplinary actions related to safety violations
- To systematically identify and evaluate hazards associated with specific job tasks before work begins (Correct answer)
- To calculate workers' compensation costs for each department
- To schedule mandatory safety training sessions for new hires
Correct answer: To systematically identify and evaluate hazards associated with specific job tasks before work begins
A JHA (also called Job Safety Analysis) is a proactive process that breaks a job into steps, identifies potential hazards at each step, and recommends controls to eliminate or reduce those hazards before an incident occurs.
Question 2: Under OSHA's Lockout/Tagout (LOTO) standard (29 CFR 1910.147), what is the correct term for the procedure that renders a machine unable to be energized during servicing?
- Hazard isolation
- Energy control procedure (Correct answer)
- Zero mechanical state
- Residual energy release
Correct answer: Energy control procedure
OSHA 1910.147 requires employers to develop written energy control procedures (also called lockout/tagout procedures) that specify the steps to isolate and de-energize equipment before maintenance or servicing activities.
Question 3: A safety supervisor notices a worker performing a task without required PPE but no injury has occurred. What is the MOST appropriate immediate action?
- File an incident report and wait for the next safety meeting to address it
- Allow the worker to finish the task to avoid disrupting productivity, then counsel afterward
- Stop the work, correct the hazard by ensuring PPE is donned, and document the observation (Correct answer)
- Issue a formal written warning without speaking to the worker directly
Correct answer: Stop the work, correct the hazard by ensuring PPE is donned, and document the observation
Supervisors have a duty to intervene immediately when an unsafe condition or behavior is observed. Stopping the work, correcting the hazard on the spot, and documenting the event follows the hierarchy of supervisory safety responsibility and prevents a potential injury.
Question 4: In a risk assessment matrix, risk level is determined by combining which two factors?
- Frequency of exposure and cost of controls
- Likelihood of occurrence and severity of potential harm (Correct answer)
- Number of workers exposed and regulatory penalty amount
- Duration of task and worker experience level
Correct answer: Likelihood of occurrence and severity of potential harm
A standard risk matrix plots the probability (likelihood) that a hazard will cause an event against the severity (consequence) of the resulting harm. The intersection of these two axes yields a risk rating (e.g., low, medium, high, critical).
Question 5: What is the primary goal of a safety incident investigation?
- To assign blame and determine which employee is at fault
- To comply with insurance reporting deadlines
- To identify root causes so that corrective actions can prevent recurrence (Correct answer)
- To calculate the total recordable incident rate (TRIR) for the year
Correct answer: To identify root causes so that corrective actions can prevent recurrence
Incident investigations are fundamentally a learning and prevention tool. By identifying root causes — including management system failures, not just worker error — organizations can implement corrective actions that reduce the likelihood of similar events in the future.
Question 6: Under OSHA's Hazard Communication Standard (HazCom 2012, 29 CFR 1910.1200), how many sections are required on a Safety Data Sheet (SDS)?
- 8
- 10
- 16 (Correct answer)
- 24
Correct answer: 16
HazCom 2012 aligns with the Globally Harmonized System (GHS) and mandates a standardized 16-section SDS format covering chemical identity, hazards, composition, first aid, fire-fighting, handling, exposure controls, physical/chemical properties, and more.
