FLHA examples for every trade
A Field Level Hazard Assessment (FLHA) is the safety document you fill in before the job starts. Employers must identify hazards before work starts and control them, and workers must be told about them. A field level hazard assessment is done on site, at the start of each shift or task, and reviewed again when conditions change.
