When performing a Job Hazard Analysis (JHA) for a blasting operation, which step should be completed FIRST?
Answer: Break the job into discrete sequential tasks
A JHA begins by breaking the job into its component tasks before hazards associated with each task can be identified and controlled.
Which qualitative risk assessment matrix axis combination correctly defines 'risk level'?
Answer: Likelihood × Consequence
Risk is universally defined in safety management as the product of Likelihood (probability of occurrence) and Consequence (severity of outcome).
A blaster discovers that 15% of the detonators in a shipment have resistance values outside the manufacturer's specified tolerance. The correct QA response is to:
Answer: Reject the entire lot and notify the supplier
A 15% defect rate far exceeds acceptable quality limits for initiating devices; the entire lot must be quarantined and the supplier notified per industry QA protocols.
The hierarchy of controls, ranked from most to least effective for explosives operations, begins with:
Answer: Elimination
Elimination of the hazard is always the most effective control; subsequent tiers include substitution, engineering controls, administrative controls, and PPE.
Under ATF regulations, a licensed explosives dealer must conduct a physical inventory of all explosive materials at minimum:
Answer: Annually
27 CFR Part 555 requires licensed dealers to conduct a complete physical inventory of explosive materials at least annually.
Which blasting risk scenario represents a 'high likelihood / low consequence' classification?
Answer: A truck tire puncture from fly-rock on a haul road
Tire damage from fly-rock is a relatively frequent, low-severity event — property damage without injury — fitting the high-likelihood/low-consequence cell.
Root cause analysis of a blasting incident revealed that the crew skipped the pre-blast area inspection because they were behind schedule. This failure is best categorized as a:
Answer: Latent organizational failure
Schedule pressure is a latent organizational condition (systemic weakness) that created the environment for the procedural shortcut, making it a latent organizational failure.
