Staying Safe with Ladders Near Electricity
The Problem
Ladders and electricity are a dangerous combination. Metal ladders or improperly positioned ladders can create a direct path to ground if they come into contact with live power lines or electrical equipment. Even worse, electrical current can arc across several metres, causing injury without direct contact. Today, we’ll discuss how to prevent these hazards by selecting the correct ladder, positioning it properly, and taking additional precautions.
Identify the Hazards
Safety Practices and Preventative Measures
1. Choose the Right Ladder
- Use Non-Conductive Side Rails: Fiberglass or plastic-reinforced ladders are ideal for work near electricity because they do not conduct current.
- Wooden Ladders: Dry, well-maintained wooden ladders are acceptable, but avoid using them if they are wet or deteriorating.
2. Safe Setup Practices
- Maintain Clearance Distances: Keep ladders well away from power lines to prevent contact if the ladder shifts. Consider the ladder’s full reach and potential movement.
- Be Mindful of Materials: Avoid handling long, conductive materials like metal pipes near overhead lines. Reposition the ladder if necessary to stay clear of hazards.
3. Avoid Electrical Arcing
- Safe Distances: Electricity can arc several metres depending on voltage. Maintain a minimum 3 to 4 metres clearance from overhead power lines, or follow guidance from the utility company.
- Consult Your Supervisor or Employer: Always check site-specific clearance requirements and procedures before starting work.
4. Additional Safety Measures
- Isolation Procedures: Follow lockout/tagout or permit-to-work procedures when working near live electrical equipment.
- Coordinate with Utilities: If overhead lines are within reach, contact the utility provider to arrange barriers, insulators, or temporary shutdowns.
Real-Life Case or Scenario
On a job site, a worker used a metal ladder near an overhead power line. While repositioning the ladder, it came into contact with the energized line. The worker suffered serious electrical burns. This incident could have been prevented by using a fiberglass ladder and maintaining the required clearance distance.
Employee Responsibilities
- Always use non-conductive ladders when working near electricity.
- Inspect ladders to ensure they are clean, dry, and in good condition.
- Maintain safe distances from all power lines.
- Be cautious when handling materials that could create a path to a power source.
- Report any damaged equipment or unsafe conditions immediately.
Employer Responsibilities
Discussion & Questions
- Has anyone worked near electrical lines with ladders? What precautions did you take?
- Are there any additional tips or concerns we should discuss about ladder safety near electricity?
Encourage everyone to share experiences and raise any concerns.
Commitment/Action Plan
Let’s commit to using the correct ladder, maintaining safe distances, and inspecting our equipment before every job. If you’re ever unsure, stop and seek guidance before continuing.
Wrap-Up
Electricity can be deadly. Even without direct contact, arcing can cause serious harm. By using non-conductive ladders, maintaining safe distances, and planning ahead, we can prevent serious incidents. Thank you for prioritizing safety.
Standards Overview
Canadian occupational health and safety guidelines for electrical safety and working at heights require:
- Use of non-conductive ladders (such as fiberglass) when working near live electrical lines.
- Maintaining minimum approach distances (typically 3 metres or as specified by local regulations) from power lines unless they are de-energized or properly insulated.
- Having planning and controls in place when working near electrical services to ensure worker safety.
