How to complete a field-level hazard assessment
A practical six-step approach to documenting the task, site conditions, hazards, controls, worker acknowledgements and changes during the job.
Step 1 — Describe the actual work
State the task clearly, including equipment, sequence and who is involved. “Repair communications antenna on a 30-foot tower” is more useful than “maintenance.”
Step 2 — Verify site information
Confirm location and access, weather, nearby operations, ground conditions, emergency contacts and the appropriate medical facility. Automatically retrieved information still needs worker verification.
Step 3 — Break the job into steps
Identify the main stages of work. For example: arrive and secure site; inspect equipment; set up controls; perform task; clean up and leave the site safe.
Step 4 — Identify hazards and controls
For each step, name realistic hazards and describe specific precautions. Consider eliminating a hazard first, then engineering and administrative controls, and appropriate PPE. Check controls against employer requirements.
Step 5 — Brief the crew and acknowledge
Ask every involved worker to review the assessment and record their acknowledgement before the affected work begins. A signature documents acknowledgement; it is not proof that all risks are eliminated.
Step 6 — Reassess and close out
When conditions or controls change, stop and reassess as required. Record new observations and photographs during work, then complete and retain the final signed document.
