Job hazard analysis uses which four systems together?

• A. one on one observation method, group discussion, hazard initiation, hierarchy control categorization
• B. risk assessment, incident reports, training records, engineering controls
• C. checklists, audits, SOPs, risk ranking
• D. work sampling, time-motion study, root cause analysis, control barriers

Answer: (A)

Job hazard analysis blends four elements to be effective: direct task observation, collaborative worker input, structured hazard initiation, and applying the hierarchy of controls to select safeguards. Observing the task one-on-one reveals how work is really done and what hazards show up in practice, which can differ from what procedures say. Bringing workers together in group discussions taps practical knowledge and helps uncover hazards that an observer might miss, while also building buy-in for changes. Hazard initiation provides a formal way to surface potential hazards at each step, ensuring the analysis is thorough and not superficial. Finally, using the hierarchy of controls to categorize and prioritize safeguards ensures the most effective measures are chosen—eliminating the hazard or substituting with a safer option first, then engineering controls, administrative controls, and PPE as a last resort. This combination makes the process proactive, task-specific, and actionable, rather than relying on generic tools or past incidents alone.
