The primary purpose of a pre-task safety briefing (toolbox talk) related to hazard identification is to:
Answer: Ensure all workers understand site-specific hazards and controls before starting work
Pre-task briefings communicate task-specific hazards and controls so every worker starts the job aware of risks and expected safe behaviors.
Which of the following is a leading indicator used in proactive hazard identification programs?
Answer: Number of safety observations completed per week
Safety observations measure proactive safety activity before incidents occur, making them a leading indicator rather than a lagging measure.
In infrastructure construction, a 'permit-to-work' system primarily functions to:
Answer: Control access to high-risk activities through formal hazard review and sign-off
A permit-to-work system ensures high-risk tasks are formally assessed, authorized, and controlled before work begins.
When assessing the risk of working at heights on an infrastructure project, which control should be given the highest priority?
Answer: Eliminating the need to work at height through redesign or mechanization
Elimination — removing the need to work at height — is the highest-priority control in the hierarchy of controls.
A 'critical task inventory' in an IHSA safety management program is used to:
Answer: Identify and prioritize tasks with the highest potential for serious injury or fatality
A critical task inventory focuses hazard assessment resources on tasks where consequences of failure are most severe.
FMEA (Failure Mode and Effects Analysis) is distinguished from FTA because FMEA:
Answer: Works bottom-up from individual component failures to assess system-level effects
FMEA takes a bottom-up approach, analyzing how individual component failures propagate to affect the overall system.
Which type of hazard is most commonly overlooked during standard site inspections because it is not immediately visible?
Answer: Noise-induced hearing loss from chronic exposure
Chronic noise exposure causes cumulative hearing loss that has no immediate visible symptom and is often missed during physical site inspections.
