Practical Electrical Safety Risk Assessment Checklist for HSE Officers

Electrical Hazard Identification and Risk Assessment Checklist

Step 1 — Preliminary Assessment

Begin your electrical risk assessment by conducting a thorough preliminary evaluation of your workplace environment. This foundational step requires identifying all equipment involved in normal and abnormal operating conditions. Document all machinery, tools, and systems that utilize electrical power, including backup systems and emergency equipment. Assess the maintenance and testing activities that employees perform on electrical systems. Identify all people who may be exposed to electrical hazards, including full-time staff, contractors, temporary workers, and emergency responders. This comprehensive inventory ensures no critical equipment or personnel exposure is overlooked during the assessment process.

Step 2 — Identify Electrical Hazards

Conduct a systematic inspection of your facility to identify specific electrical hazards. Look for exposed live components that lack proper insulation or protective barriers. Examine all cables and plugs for signs of damage, cuts, or deterioration that could lead to electrical exposure. Evaluate guarding systems to ensure they are adequate and properly maintained. Check for overloaded circuits that may exceed safe amperage ratings or lack appropriate circuit protection. Verify that all electrical equipment has proper grounding systems in place to safely dissipate fault currents. Inspect areas for wet or damp conditions that could increase electrical conductivity and risk of shock. Document any temporary wiring installations that may not meet permanent installation standards. Identify defective tools that show signs of wear, damage, or malfunction. Assess the effectiveness of isolation procedures and lockout/tagout systems. Evaluate the potential for arc-flash exposure from energized equipment, particularly in high-fault-current locations.

Step 3 — Identify Who Could Be Harmed

Electrical hazards affect multiple categories of workers throughout your organization. Electricians and electrical maintenance technicians face daily exposure during installation, maintenance, and troubleshooting activities. Maintenance technicians working on mechanical systems may encounter electrical hazards incidentally. Equipment operators may contact energized components during normal operations or emergency procedures. Cleaning and housekeeping staff may inadvertently create electrical hazards or come into contact with equipment. Contractors performing work on premises require specific awareness of electrical hazards present in your facility. Visitors to your workplace, though typically supervised, may be exposed to electrical hazards. Untrained or newly hired employees may not recognize electrical hazards in their work environment. Emergency responders including firefighters and emergency medical personnel may encounter electrical hazards during emergency situations. Document the frequency and duration of each group's exposure to identified hazards.

Step 4 — Rate Likelihood and Severity

Develop a risk rating system using a simple matrix based on multiple factors. Assess likelihood using a scale ranging from rare occurrences to almost certain events. Evaluate severity potential from minor injuries to fatality or multiple casualties. Consider exposure levels by determining the number of people at risk and the frequency of their contact with hazards. Document existing controls, rating them as effective, inadequate, or absent. Calculate risk levels by combining these factors systematically. However, avoid treating the calculated numerical risk score as the only decision factor in your safety decisions. Professional judgment, industry standards, and regulatory requirements must guide your final risk determinations.

Step 5 — Select Controls and Assign Actions

Implement controls following the established hierarchy of risk control measures. First priority is to eliminate unnecessary electrical exposure by redesigning processes to avoid electrical hazard contact. De-energise and isolate equipment before work whenever possible, using established lockout/tagout procedures. Substitute safer equipment or implement lower-risk methods that reduce hazard severity. Install engineering controls such as barriers, insulation, and protective devices. Apply administrative controls including procedures, training, and work scheduling to minimize exposure. Use appropriate Personal Protective Equipment (PPE) for remaining risks that cannot be eliminated through other means. Assign specific responsibility and completion dates for each control measure. Designate supervisors or managers to verify proper implementation and ongoing effectiveness.

Applicable Standards and Regulatory Requirements

Electrical safety compliance requires adherence to multiple regulatory frameworks. OSHA 29 CFR 1910 Subpart S establishes electrical standards for general industry. OSHA 29 CFR 1910.147 addresses lockout/tagout requirements for hazardous energy control. OSHA 29 CFR 1926 Subpart K covers electrical standards for construction activities. NFPA 70E provides recommended safety-related work practices and standards for electrical equipment maintenance. Applicable national wiring regulations specific to your jurisdiction must be incorporated into your assessment. Company electrical-safety procedures should exceed minimum regulatory requirements based on your specific hazards and operating conditions.

Important Disclaimer: International organisations must verify the legal requirements that apply in each operating country where they operate, as electrical safety standards vary significantly by jurisdiction and region.

Recording and Closing Electrical Inspection Findings

Documentation Requirements

Every electrical inspection finding must be recorded with complete and accurate information to ensure proper tracking and corrective action. Each finding requires documentation of the exact location within your facility, clearly identifying the building, floor, room, or area where the hazard exists. Equipment identification must be specific, including the equipment type, model, serial number, and any identifying tags or labels. Photograph all findings from multiple angles to provide visual evidence of the hazard and current conditions. Describe the hazard clearly and identify the potential consequence, including the type and severity of injury that could result from exposure to this hazard. Document all existing controls currently in place to manage or mitigate the hazard, rating their effectiveness.

Risk Rating and Action Assignment

Assign a risk rating using your established risk matrix, clearly stating whether the hazard is low, medium, or high risk. Identify the immediate action required, such as equipment removal from service, area isolation, or restriction of worker access. Designate a specific corrective-action owner who is accountable for implementing the required remedial measures. Establish a realistic deadline for completion of corrective actions, considering the risk level and resource availability. Document completion evidence, which may include photographs of corrected conditions, test certificates, maintenance records, or inspection reports. Require verification by a competent person who confirms that corrective actions have been implemented effectively and that the hazard has been adequately controlled.

Finding Closure and Risk Register

Maintain an electrical risk register that tracks all identified findings from inspection through closure. Unresolved findings should remain active on the electrical risk register until verified as closed by a competent person. This ongoing tracking ensures that no corrective actions are forgotten or delayed indefinitely. Regularly review the risk register during safety meetings and management reviews. Update findings when corrective actions are completed, documenting the completion date and verifying person. Archive closed findings for future reference and to demonstrate your organization's commitment to electrical safety improvements.

Adapting the Checklist to Different Industries

Construction Industry

Construction sites require special focus on temporary power installations, including temporary distribution systems and portable generators. Extension leads and trailing cables present significant hazards on construction sites and must be regularly inspected for damage. Overhead power lines pose electrocution risks to workers and equipment operators, requiring safe working distances and coordination with utility companies.
