Carrying out a working at height risk assessment involves systematically identifying potential hazards, evaluating the risks associated with those hazards, and implementing control measures to mitigate or eliminate those risks.
Here’s a step-by-step guide to conducting a comprehensive working at height risk assessment:
Identify the Hazards
Start by identifying all potential hazards related to working at height. Consider the following factors:
-
Work Environment: Identify areas where workers will be operating at height, such as roofs, ladders, scaffolding, or elevated platforms.
-
Access and Egress: Evaluate how workers will access the height and return safely to the ground.
-
Weather Conditions: Assess how weather (e.g., wind, rain, ice) might affect safety.
-
Fragile Surfaces: Identify any surfaces that could break or collapse under weight.
-
Falling Objects: Consider the risk of tools, materials, or equipment falling from height.
-
Worker Conditions: Account for the physical condition and training of workers, including fatigue or health issues that could impair safety.
Assess the Risks
Once hazards are identified, evaluate the risks associated with each hazard:
-
Likelihood of Occurrence: Determine how likely the hazard could lead to an accident or injury.
-
Severity of Consequences: Consider the potential severity of injuries or damage that could result from the hazard.
-
Frequency of Exposure: Evaluate how often workers will be exposed to the hazard.
-
Existing Control Measures: Review any current measures in place to reduce the risk and assess their effectiveness.
Implement Control Measures
To control the risks identified, apply the hierarchy of control measures:
Elimination: Where possible, eliminate the need to work at height by using equipment or tools that allow the task to be performed from the ground.
Substitution: Use safer alternatives, such as using a mobile elevated work platform (MEWP) instead of ladders.
Engineering Controls: Install guardrails, scaffolding, or other physical barriers to prevent falls.
Administrative Controls: Implement safe work procedures, provide training, and establish clear guidelines on working at height.
Personal Protective Equipment (PPE): Use fall arrest systems, harnesses, and helmets to protect workers in case of a fall.
Record the Findings
Document the risk assessment process, including:
-
Identified Hazards: A list of all hazards identified during the assessment.
-
Risk Analysis: A summary of the risks associated with each hazard, including the likelihood and severity of potential incidents.
-
Control Measures: Details of the control measures implemented to mitigate the risks.
-
Responsible Personnel: Assign responsibility for implementing and monitoring each control measure.
Communicate the Risks
Ensure that all workers and relevant personnel are informed of the risks and the control measures in place. Provide training and clear instructions on safe working procedures, use of equipment, and emergency protocols.
Review and Revise
A working at height risk assessment is not a one-time activity. Regularly review and update the assessment to reflect any changes in the work environment, new hazards, or improved control measures. Also, revise the assessment after any incidents or near-misses.
Monitor the Implementation
Finally, regularly monitor the effectiveness of the control measures. Ensure that workers are following safe work practices and that the control measures are functioning as intended. Conduct periodic safety audits and inspections to maintain a safe working environment.
Summary
Carrying out a working at height risk assessment is crucial for preventing accidents and ensuring the safety of workers. By systematically identifying hazards, assessing risks, implementing control measures, and continuously monitoring and reviewing the process, you can effectively manage the risks associated with working at height.
