Write a risk assessment for Site hazard identification

A comprehensive workplace risk assessment and site hazard identification procedure should use a documented job hazard analysis (JHA) or hazard assessment process that identifies tasks, hazards, who or what is exposed, likely consequences, and the controls needed before work begins. A PPE hazard assessment should include the jobs or tasks performed, the hazards present, where the hazards are located, the likelihood of injury, the severity of potential injury, and the types of PPE needed. For task-level analysis, break each job into steps, observe the work, identify hazards at each step, evaluate exposure, precursors, environmental conditions, and consequences, then determine controls and safe procedures. [5] [3] [3]

• Conduct a baseline survey of the entire workplace, including processes, tasks, equipment, materials, and site conditions.
• Break jobs into individual task steps and review routine, non-routine, and changed conditions.
• Identify hazard types such as struck-by, caught-in/between, falls, chemical exposure, dust, electrical contact, ergonomic stressors, heat, optical radiation, and environmental hazards.
• Determine who may be exposed, body parts at risk, hazard sources, and what could go wrong.
• Evaluate risk using severity and probability, then assign a risk code or priority ranking to focus corrective action.
• Document findings and update them when equipment, materials, processes, or site conditions change.

[7] [17] [17] [11] Hazard recognition should combine walkthrough inspections, employee involvement, review of SDSs and equipment manuals, and analysis of incident history and near misses. Employees who perform the work should be involved because they often know the task hazards best. Hazard assessments should also be repeated at each site as needed and whenever equipment, materials, or work processes change. Regular inspections and follow-up are necessary to verify that hazards remain controlled and to identify new ones. [3] [7] [6] [2]

Control measures should follow the hierarchy of controls in order of effectiveness: elimination, substitution, engineering controls, administrative controls, and PPE. The preferred approach is to remove the hazard entirely or reduce exposure through design, isolation, guarding, enclosure, ventilation, or process changes before relying on worker behavior or PPE. PPE should be treated as the last line of defense or as supplemental protection when higher-level controls are not feasible, not sufficient, or when temporary or emergency conditions exist. [12] [6] [1] [4]

• Elimination: remove the hazard entirely, such as redesigning work to be done from the ground instead of at height.
• Substitution: replace the hazard with a less hazardous material, process, or tool.
• Engineering controls: isolate workers from hazards using guards, enclosures, ventilation, guardrails, or safer equipment.
• Administrative controls: implement written procedures, permits, scheduling limits, signage, training, inspections, housekeeping, maintenance, and supervision.
• PPE: select hazard-specific equipment only after assessing the hazard and ensuring proper fit, use, and enforcement.

[6] [13] Mitigation and incident-prevention actions should include safe job procedures, pre-job briefings, emergency planning, training, housekeeping, maintenance, and investigation of incidents and near misses. Before starting work, hold a site-specific briefing to review the JHA, discuss the day's hazards, and address any site conditions not already captured. If conditions change, stop and conduct an additional briefing. Emergency procedures for spills, fires, injuries, and other unplanned events should be written, equipment should be available, and workers should practice the response. [3] [3] [4] [8]

• Investigate injuries, illnesses, incidents, and near misses to identify root hazards and failed controls.
• Track trends in injuries and exposures to prioritize recurring risks.
• Maintain good housekeeping to prevent slips, fires, dust accumulation, and unsafe storage conditions.
• Keep equipment maintained and safety devices in place.
• Use personal hygiene controls where relevant, including handwashing and prohibiting eating, drinking, or smoking in contaminated work areas.
• Monitor implemented controls and revise them if they are ineffective or create new hazards.

[6] [8] [8] [4] [10] PPE requirements must be based on the specific hazards identified at the workplace and task. Common PPE categories include eye and face, head, hand, foot, leg, torso/body, hearing, respiratory, fall protection, and personal flotation devices where applicable. Respiratory protection requires special attention when exposures may exceed permissible exposure limits or involve oxygen-deficient, toxic, or IDLH atmospheres. PPE selection should be documented, communicated to affected employees, properly fitted, and enforced. [10] [7] [16] [13]

Safe work practices should be written into task procedures and reinforced through training. At a minimum, procedures should define the job steps, hazards, required controls, required PPE, emergency actions, and stop-work expectations when conditions change. Training should ensure workers understand the hazards and risks of their jobs, the controls in place, and how to protect themselves and co-workers. For higher-risk work, such as work at heights, procedures should include planning, equipment selection, fall protection, rescue or emergency response, and competency verification. [11] [8] [14] [15]

For OSHA and regulatory documentation compliance, employers should maintain written hazard assessment records that clearly certify the assessment and show who performed it, where it was performed, and when. General industry employers must document PPE hazard assessments with a certification statement, workplace name, certifier name, and assessment date. Keep the assessment on file, update it as conditions change, and use worksheets or JHA forms that capture task steps, hazard types, body parts at risk, severity, probability, risk code, and selected controls. A strong compliance record also includes inspection records, training records, incident investigations, corrective actions, and evidence that employees were informed of PPE selection decisions.
