CMRP Health, Safety, and Environment 2 — Questions and Answers
Question 1: What is the primary purpose of a Lockout/Tagout (LOTO) procedure?
- To prevent unauthorized equipment use
- To protect workers from unexpected energization during maintenance (Correct answer)
- To secure the facility after hours
- To label equipment for inventory
Correct answer: To protect workers from unexpected energization during maintenance
LOTO procedures ensure hazardous energy sources are isolated and de-energized before maintenance work begins.
LOTO is governed by OSHA 29 CFR 1910.147. The process involves identifying all energy sources, shutting down and isolating each, applying locks and tags, verifying zero energy state, then performing work.
Question 2: What does a Job Safety Analysis (JSA) evaluate?
- Employee job performance
- The hazards associated with each step of a specific job task (Correct answer)
- Equipment maintenance schedules
- Financial risks of a project
Correct answer: The hazards associated with each step of a specific job task
A JSA breaks a job into individual steps and identifies hazards with appropriate control measures for each step.
A JSA is a systematic process: break the job into steps, identify hazards at each step, then define preventive measures following the hierarchy of controls. JSAs should be reviewed when jobs change or after incidents.
Question 3: According to the hierarchy of controls, which method is the most effective for eliminating workplace hazards?
- Personal protective equipment
- Administrative controls
- Engineering controls
- Elimination of the hazard (Correct answer)
Correct answer: Elimination of the hazard
Elimination physically removes the hazard completely rather than managing exposure to it.
The hierarchy from most to least effective: Elimination, Substitution, Engineering controls, Administrative controls, PPE. Higher-level controls are preferred because they don't depend on human behavior.
Question 4: What is a confined space entry permit required for?
- Any indoor work area
- Spaces with limited entry/exit that may contain hazardous atmospheres (Correct answer)
- Offices without windows
- Equipment rooms with multiple exits
Correct answer: Spaces with limited entry/exit that may contain hazardous atmospheres
Confined space entry permits are required for spaces with limited access that may contain hazardous atmospheres or other serious safety risks.
OSHA defines a permit-required confined space as one with limited entry/exit, not designed for continuous occupancy, and containing hazards such as hazardous atmosphere, engulfment potential, or converging walls.
Question 5: What is the purpose of a Management of Change (MOC) process?
- To manage employee transfers
- To systematically evaluate risks associated with changes to equipment, processes, or procedures (Correct answer)
- To track supplier pricing changes
- To update organizational charts
Correct answer: To systematically evaluate risks associated with changes to equipment, processes, or procedures
MOC ensures changes to equipment, processes, or procedures are evaluated for safety, health, and environmental impacts before implementation.
MOC is required by OSHA PSM and EPA RMP regulations. The process evaluates technical basis, safety implications, impact on operating procedures, and required modifications to safety systems. All affected personnel must be trained.
Question 6: What type of investigation should be conducted after a workplace incident?
- Financial audit
- Root cause analysis investigation (Correct answer)
- Employee satisfaction survey
- Inventory check
Correct answer: Root cause analysis investigation
Root cause analysis determines underlying causes, going beyond immediate causes to identify systemic issues.
Effective investigations use techniques such as 5-Why, fault tree analysis, and barrier analysis. The investigation examines direct causes, contributing causes, and root causes including management system deficiencies.
