Working Safely in Wet Environments with Electricity
The Problem
Electricity and water are a dangerous combination. But by following safe work practices, staying alert, and using the right equipment, we can prevent injuries and save lives. Thank you for making safety your priority—remember, it only takes a small mistake to cause a serious accident.
Identify the Hazards
- Electric Shock: Water reduces electrical resistance, increasing the likelihood of shock when equipment or cables are exposed to moisture
- Damaged Equipment: Wet conditions can lead to corrosion or degrade insulation, exposing live electrical components
- Slips and Falls: Wet surfaces raise the risk of slips and falls, which can increase the chance of accidental contact with live equipment
- Unintentional Contact: Wet gloves or boots may become conductive, putting workers at greater risk of electric shock
Safety Practices and Preventative Measures
Inspect Equipment Before Use
- Check cords, plugs, and tools for damage—especially signs of moisture or water ingress
- Do not use electrical equipment that is wet unless it is specifically designed and rated for wet conditions
Use Ground Fault Circuit Interrupters (GFCIs)
- Always plug tools and portable equipment into GFCI-protected outlets to reduce the risk of electric shock
- Test the GFCI before use using the built-in test button to ensure it’s functioning properly
Wear Proper Personal Protective Equipment (PPE)
- Use rubber-insulated gloves and electrically rated boots where required
- Wear slip-resistant footwear to reduce the chance of falling on wet surfaces
Use Insulating Mats and Barriers
- Stand on dry, insulated mats or platforms when working near electrical sources in wet areas
- Use barriers or protective covers to keep water away from electrical components
Dry Equipment Thoroughly
- If tools or cords get wet, dry them completely and have them inspected by a competent person before use
- Do not resume use until the item has been verified as safe
Limit Exposure to Wet Conditions
- Avoid working with electricity in rain, standing water, or other high-risk wet environments unless absolutely necessary
- Use portable shelters, tarpaulins, or protective covers to shield electrical gear from moisture
Report Hazards Immediately
- If you see water near electrical panels, cables, or equipment, stop work immediately and report the hazard to your supervisor
Real-Life Case or Scenario
In a recent incident, a worker using an electric drill outdoors during light rain suffered a severe electric shock. The drill was not rated for wet conditions, and the outlet did not have GFCI protection. The worker was hospitalized but survived. This accident could have been prevented by using properly rated tools and ensuring all equipment was connected to a GFCI-protected outlet.
Employee Responsibilities
- Inspect all tools and equipment before use, especially when working in wet conditions
- Use Ground Fault Circuit Interrupters (GFCIs) and test them regularly
- Wear appropriate personal protective equipment (PPE) for wet environments
- Avoid using damaged or wet tools, and report any hazards to your supervisor immediately
Employer Responsibilities
- Provide Ground Fault Circuit Interrupter (GFCI) protection for all electrical outlets used in wet or damp environments
- Supply appropriate personal protective equipment (PPE) and tools that are rated for use in wet conditions
- Ensure all employees are trained on the hazards of working with electricity in wet environments and know how to work safely
- Maintain and inspect electrical equipment regularly to ensure it remains safe and compliant with manufacturer and regulatory standards
Discussion & Questions
- “What types of electrical hazards have you encountered while working in wet conditions?”
- “Does anyone know how to test a GFCI? Let’s review that together.”
Encourage employees to share their concerns or experiences with similar situations
Commitment/Action Plan
Let’s commit to inspecting all tools and using GFCI protection every time we work in wet environments. Starting today, take a few extra moments to ensure all electrical equipment is safe and dry before beginning work.
Wrap-Up
Electricity and water are a dangerous combination, but by following these safety practices, we can prevent accidents and injuries. Thank you for prioritizing safety on the job site. Remember, it only takes a small mistake for a big accident to happen—stay alert and stay safe.
Standards Overview
Under Canadian occupational health and safety legislation, employers and supervisors have a duty to identify, eliminate, or minimize risks to workers’ health and safety—including electrical hazards in wet or damp environments. The Canadian Centre for Occupational Health and Safety (CCOHS) and provincial safety authorities require:
- Use of Ground Fault Circuit Interrupters (GFCIs) for all portable and hand-held electrical equipment used in wet locations
- Regular inspection and maintenance of electrical equipment exposed to moisture or damp conditions
- Worker training in electrical hazard identification and safe work practices
- Use of weather-rated tools, cords, and protective devices to reduce electrical risk in wet environments
