How is job hazard analysis (JHA) performed in construction?

Job Hazard Analysis (JHA) process: (1) Select job/task for analysis - prioritize high-risk activities, (2) Break job into steps - observe actual work sequence, (3) Identify hazards at each step - physical, chemical, ergonomic, (4) Assess risk - likelihood and severity, (5) Determine controls - eliminate, substitute, engineering controls, administrative controls, PPE (hierarchy), (6) Document and communicate to workers, (7) Review and update as conditions change. JHAs are prepared before work begins and reviewed in toolbox talks. Essential for high-risk activities like working at heights, confined spaces, hot work.
