Electrical Equipment Safety - Inspection, Use and Maintenance

Welcome back, let's Build Smart & Build Safe! We've covered the fundamentals of electrical safety, working around power lines, and the critical roles of grounding and bonding. Today, we're focusing on the electrical equipment we use every day: inspection, proper use, and regular maintenance are paramount to preventing electrical incidents.

The tools and equipment that power our work can become sources of danger if not handled with care and diligence. Regular inspection can identify potential hazards before they lead to accidents, proper use ensures we're not creating unnecessary risks, and consistent maintenance keeps our equipment in safe operating condition.

Safe Inspection of Electrical Equipment:

Before Each Use:

• Extension Cords:

  • Inspect the entire length: Look for cuts, fraying, exposed wires, damaged insulation, and loose connections.

  • Check plugs and connectors: Ensure they are not cracked, bent, or have missing or loose prongs, especially the grounding prong.

  • Verify the cord is the correct type and rating for the intended use (e.g., outdoor-rated for outdoor use).

• Portable Power Tools:

  • Inspect cords and plugs: Follow the same guidelines as for extension cords.

  • Check for cracks or damage to the tool housing.

  • Verify the on/off switch operates properly.

  • Look for any loose or missing parts.

• Temporary Lighting:

  • Inspect cords and connections for damage.

  • Ensure bulbs are properly installed and protected by guards.

  • Verify that lighting used in wet locations is approved for that use.

• Ground Fault Circuit Interrupters (GFCIs):

  • Test GFCIs before each use: Press the "test" button, which should trip the "reset" button. Then, press the "reset" button to restore power. If the GFCI doesn't trip or reset correctly, remove it from service.

Proper Use of Electrical Equipment:

• Use Equipment for Its Intended Purpose: Don't overload tools or use them in ways they weren't designed for.

• Avoid Overloading Circuits: Don't plug too many tools into a single outlet or extension cord. This can cause overheating and fires.

• Use the Right Cord Length and Gauge: Select extension cords that are long enough to reach the power source without stretching, and ensure the gauge (thickness) is appropriate for the power requirements of the tool. Undersized cords can overheat and cause voltage drops.

• Keep Cords Away from Hazards: Prevent cords from being run through doorways, across walkways, or where they could be pinched, cut, or damaged by foot traffic or equipment.

• Avoid Wet Conditions: Unless the equipment is specifically designed for wet use, keep it dry. Never use electrical tools in the rain or standing water.

• Use Proper Connectors: Ensure plugs and receptacles match and are securely connected. Avoid using makeshift connections.

Regular Maintenance of Electrical Equipment:

• Follow Manufacturer's Instructions: Adhere to the manufacturer's recommendations for maintenance and care.

• Regular Cleaning: Keep tools and cords clean and free of dust and debris.

• Professional Repairs: Only qualified electricians should perform repairs on electrical equipment. Never attempt to fix damaged equipment yourself unless you are a qualified professional.

• Remove Damaged Equipment from Service: Immediately tag out and remove any damaged electrical equipment from service to prevent accidental use.

• Scheduled Inspections: Implement a schedule for more thorough inspections of electrical equipment by competent personnel.

• Lockout/Tagout (LOTO): Before performing any maintenance or repairs on electrical equipment, always follow proper LOTO procedures to de-energize the equipment and prevent accidental startup.

By making inspection, proper use, and regular maintenance integral to our daily routines, we can significantly reduce the risk of electrical incidents and ensure that the power that drives our work does so safely.

Tomorrow, on Fall Protection Friday, we'll address the added complexities of working at heights when electrical hazards are present. Stay safe and take care of your equipment!
