Which risk assessment methodology uses a bow-tie diagram to visualize both the causes of a hazardous event and its consequences?
Answer: Bow-Tie Analysis
Bow-Tie Analysis places the hazardous event at the center, with threats on the left (fault tree) and consequences on the right (event tree), making it ideal for visualizing barriers.
Under MSHA regulations, what is the maximum permissible exposure limit (PEL) for respirable coal dust in underground coal mines?
Answer: 1.5 mg/m³
MSHA's 2014 rule set the PEL for respirable coal dust at 1.5 mg/m³ (down from 2.0 mg/m³) to reduce the risk of black lung disease.
A mine safety manager conducts a risk matrix assessment and rates a hazard as 'likely' with 'major' severity. What is the most appropriate next action?
Answer: Implement immediate corrective controls and re-evaluate
A 'likely' probability combined with 'major' severity places the risk in the high or critical category, requiring immediate corrective action before work continues.
Which of the following best describes the hierarchy of controls as applied in mine safety?
Answer: Elimination → Substitution → Engineering → Administrative → PPE
The hierarchy of controls prioritizes eliminating hazards first, then substitution, engineering controls, administrative controls, and PPE as the last line of defense.
What does ALARA stand for in the context of radiation and occupational health exposure?
Answer: As Low As Reasonably Achievable
ALARA means 'As Low As Reasonably Achievable' and is a radiation protection principle requiring that exposures be kept as low as possible beyond just meeting regulatory limits.
Which federal agency has primary jurisdiction over occupational safety and health in surface metal/nonmetal mines?
Answer: MSHA
MSHA (Mine Safety and Health Administration) has exclusive jurisdiction over all mining operations under the Federal Mine Safety and Health Act of 1977, superseding OSHA.
A near-miss incident in a mine where a rock fall narrowly missed a worker should be treated as:
Answer: A valuable learning opportunity requiring investigation equal to an actual injury
Near-misses reveal system failures and uncontrolled hazards; investigating them with the same rigor as actual incidents is fundamental to proactive safety management and preventing future fatalities.
