CMSP Management Systems, Regulations & Assurance 2 — Questions and Answers
Question 1: Under MSHA's Part 46 training regulations, which category of miner must complete at least 8 hours of training before beginning work at a surface mine?
- Experienced miners transferring from another surface mine
- New miners with no prior mining experience (Correct answer)
- Miners returning from an absence of less than 12 months
- Contract miners performing non-mining tasks
Correct answer: New miners with no prior mining experience
Part 46 requires new miners (no prior mining experience) to receive at least 8 hours of training before starting work at a surface mine.
Question 2: Which MSHA document formally identifies the standard violated, the condition or practice cited, and the time allowed for abatement?
- Imminent Danger Order
- Citation (Correct answer)
- Safeguard
- Close Order
Correct answer: Citation
An MSHA Citation (issued under Section 104(a)) formally documents the violated standard, the specific condition, and the abatement deadline.
Question 3: In a mine safety management system, a 'lagging indicator' is best described as:
- A proactive measure tracking near-miss reporting rates
- A metric measuring outcomes after an event has occurred (Correct answer)
- A real-time sensor alert system
- A leading metric used to prevent future incidents
Correct answer: A metric measuring outcomes after an event has occurred
Lagging indicators measure outcomes of past events (e.g., injury rates), as opposed to leading indicators which are proactive measures.
Question 4: The Mine Act Section 115 requires operators to have approved training plans. Who must approve these plans for underground coal mines under Part 48?
- The state mining agency
- NIOSH
- MSHA's Educational Policy and Development group (Correct answer)
- The operator's safety committee
Correct answer: MSHA's Educational Policy and Development group
Under 30 CFR Part 48, training plans for underground coal mines must be approved by MSHA's Educational Policy and Development group.
Question 5: A 'pattern of violations' (POV) designation under Section 104(e) of the Mine Act is triggered when:
- Any single violation results in a fatality
- A mine has a history of significant and substantial violations of mandatory health or safety standards (Correct answer)
- A miner refuses to comply with an inspector's order
- An operator fails to pay an assessed penalty within 30 days
Correct answer: A mine has a history of significant and substantial violations of mandatory health or safety standards
Section 104(e) POV is triggered by a history of S&S violations of mandatory standards, indicating a systemic failure to maintain safe conditions.
Question 6: In the hierarchy of controls applied to mine hazards, which control is considered MOST effective?
- Personal protective equipment
- Administrative controls
- Engineering controls
- Elimination or substitution (Correct answer)
Correct answer: Elimination or substitution
Elimination or substitution sits at the top of the hierarchy of controls because it removes the hazard entirely rather than managing exposure to it.
Question 7: Which MSHA regulation requires mine operators to conduct workplace examinations to identify hazardous conditions before each shift?
- 30 CFR Part 50
- 30 CFR Part 56/57 subpart B (Correct answer)
- 30 CFR Part 100
- 30 CFR Part 48
Correct answer: 30 CFR Part 56/57 subpart B
30 CFR Parts 56/57 (Subpart B) require pre-shift workplace examinations to identify and correct hazardous conditions at surface and underground metal/nonmetal mines.
