Which OSHA standard requires employers to implement a Hazard Communication program including Safety Data Sheets?
Answer: 29 CFR 1910.1200
29 CFR 1910.1200 (Hazard Communication Standard, or HazCom) requires chemical manufacturers and employers to communicate chemical hazards through SDSs, labels, and training.
A fault tree analysis (FTA) is a hazard analysis technique that works by:
Answer: Starting with a top-level undesired event and working backward to identify root causes
FTA uses a top-down, deductive approach — beginning with an undesired event and using logic gates to trace all possible causal paths leading to it.
Which of the following best describes an 'imminent danger' situation under OSHA?
Answer: A condition where there is reasonable certainty that death or serious harm could occur immediately
OSHA defines imminent danger as any condition or practice where there is a reasonable expectation that death or serious physical harm could occur before normal enforcement procedures can protect workers.
The 'bowtie' risk model differs from traditional risk assessment because it:
Answer: Visualizes both the causes leading to a hazard event and the consequences following it simultaneously
The bowtie model shows threat pathways on the left (causes) and consequence pathways on the right, with the hazardous event in the center, providing a comprehensive view of risk.
Administrative controls differ from engineering controls primarily because they:
Answer: Rely on human behavior and procedural changes rather than physical modifications
Administrative controls manage exposure through policies, procedures, training, and work scheduling rather than physically modifying the hazard source.
A leading indicator in workplace safety is best described as:
Answer: A proactive measure tracking activities that prevent incidents before they occur
Leading indicators are proactive, preventive measures such as safety training completion rates, hazard observations reported, or near-miss investigations that predict future safety performance.
When applying the hierarchy of controls, personal protective equipment (PPE) is positioned last because:
Answer: PPE does not eliminate the hazard and depends on proper use by the employee
PPE is the last resort because it does not remove or reduce the hazard itself — it only provides a barrier, and its effectiveness depends entirely on correct and consistent use.
