Write a risk assessment for Site hazard identification

A workplace risk assessment and site hazard identification procedure should be a structured process that identifies hazards, evaluates the likelihood and severity of harm, prioritizes risks, implements controls, and verifies that those controls remain effective. A hazard is a potential source of harm, and risk assessment is the overall process of identifying hazards, assessing the risk of those hazards, and prioritizing hazards associated with a specific activity, task, or job. [1] [4]

1. Plan the assessment by defining the scope, work area, tasks, lifecycle stage, stakeholders, resources, and applicable legal and organizational requirements.
2. Assemble a competent assessment team that includes supervisors, workers familiar with the job, and consultation with the health and safety committee or representative.
3. Select the job, process, or site activity to assess, giving priority to higher-risk work, worker concerns, incident history, new work, changed work, and non-routine tasks.
4. Break the job or process into clear task steps.
5. Identify hazards for each step by reviewing the work environment, equipment, materials, work organization, routine and non-routine activities, foreseeable abnormal conditions, and affected persons including workers, contractors, visitors, and the public.
6. Assess the risk of each hazard by evaluating likelihood and severity, considering exposure, frequency, duration, number of people affected, worker capability, and possible interactions with other activities.
7. Rank or prioritize hazards so the most serious risks are addressed first.
8. Select and implement controls using the hierarchy of controls: elimination, substitution, engineering controls, administrative controls, and PPE.
9. Communicate the results to workers and supervisors before work starts and whenever conditions change.
10. Monitor, review, and re-evaluate controls regularly and after incidents, changes, or new information.

[9] [10] [11] Hazard identification should cover all aspects of work, not just normal production activities. Include routine and non-routine work such as maintenance, repair, cleaning, shutdowns, commissioning, emergencies, power outages, and extreme weather. Review the physical environment, equipment, materials, products, task steps, work organization, and the full lifecycle of the process or service. Consider hazards affecting off-site workers, teleworkers, drivers, contractors, visitors, and the public, as well as groups with different vulnerability such as young or inexperienced workers, persons with disabilities, and new or expectant mothers. [6] [7] [6]

• Workplace inspections and direct observation of tasks
• Job safety analysis or job hazard analysis
• Hazard mapping with employees using floor plans
• Review of incident, injury, illness, near-miss, and hazard reports
• Review of job descriptions, physical demands, and job demands analyses
• Worker interviews and supervisor input
• Safety Data Sheets, labels, manufacturer manuals, and operating instructions
• Exposure monitoring, testing, and sampling
• Applicable legislation, standards, codes of practice, and guidance from reputable organizations

[6] [8] [5] Risk evaluation should determine whether each hazard is likely to cause harm and how severe that harm could be. Risk is the combination of probability and severity, often expressed as risk = probability × severity. When evaluating risk, consider actual and potential exposure, duration and frequency of the task, location, tools and machinery used, interactions with nearby activities, number of people exposed, worker training and experience, foreseeable human reactions, and both current and potential workplace conditions. [3] [3] [2]

A practical way to rank risks is to use a qualitative or semi-quantitative matrix that combines severity and probability into a priority level. This helps create an action list so the highest-risk hazards are controlled first. High-risk work should not proceed until effective controls are in place; medium-risk hazards should be controlled as soon as possible; low-risk items should still be checked against any mandatory regulatory requirements. [13] [15] [18]

• Eliminate the hazard where possible, such as removing the task or performing the work from the ground instead of at height.
• Substitute with a safer material, process, tool, or method.
• Use engineering controls such as guarding, isolation, ventilation, interlocks, lifting devices, or elevated work platforms.
• Use administrative controls such as safe work procedures, permits, scheduling, restricted access, signage, supervision, training, inspections, maintenance, and emergency response plans.
• Use PPE only after feasible higher-level controls have been considered, and ensure it is matched to the hazard, fits properly, and workers are trained in its use and limitations.

[11] [16] [19] Mitigation actions and safe work practices should be documented for each task step. These typically include task-specific procedures, pre-job briefings, competency and refresher training, equipment inspections, lockout or isolation where needed, housekeeping, exposure controls, communication protocols, emergency arrangements, and stop-work authority when conditions change. Field-level risk assessments should be completed on site before work begins and updated as work progresses so crews can confirm current controls are adequate and identify any new hazards. [14] [11] [11]

Incident prevention depends on using the assessment proactively and learning from experience. Review previous injuries, illnesses, incidents, and near misses; investigate causes; correct deficiencies; and update the assessment whenever hazards are identified, work changes, new information becomes available, or work is performed in a new environment. Regular inspections and monitoring are necessary to confirm controls remain effective and to identify new hazards at each site. [2] [10] [17]

To meet occupational health and safety regulatory requirements, the procedure should require identification of applicable laws, regulations, codes, standards, and internal policies before the assessment begins; consultation with workers and health and safety representatives; documentation of the assessment process, findings, priorities, and controls; communication of results to affected workers; and retention of records showing how decisions were made. Where PPE assessments are required, document the workplace evaluated, assessor, and assessment date, and certify that the hazard assessment was completed. [10] [9] [12] [17]

• Assessment details: date, location, job or activity, assessor(s), team members, and scope
• Task breakdown: each step or phase of the work
• Hazard identification: hazard type, source, persons exposed, and potential consequences
• Risk evaluation: severity, likelihood, risk rating, and priority
• Controls: existing controls, additional required controls, responsible person, and completion date
• Verification: training completed, PPE selected where required, permits or approvals, and emergency arrangements
• Review: monitoring results, inspection findings, incident learnings, and reassessment triggers

[12] [16] [19] In practice, an effective procedure is: identify the work, involve the right people, break the job into steps, identify hazards, evaluate likelihood and severity, prioritize risks, apply the hierarchy of controls, brief the workforce, verify controls in the field, document everything, and review the assessment whenever conditions, equipment, personnel, or information change.
