TOOLBOX TALK
Electrical Safety
Sometimes the best way to power a device is not
the safest way.
Believe it or not, one of the most incorrectly used items in electrical work is the extension cord. Incorrectly using this item,
or having not proper training in electrical safety can lead to dire consequences.
Electrical shock and other hazards associated with electricity result in the deaths of over 1,000 workers each year, according to the U.S. Bureau of Labor Statistics. These deaths could be significantly decreased if employees working in areas where devices need to be powered on or electricity is integrated into the work they are doing are properly training on how to stay safe. Let’s talk tips and advice for teaching employees that the easiest way to get power to a device is not always the safest way.
Powerline 101
Understanding powerlines and where they are and how they are energized is a big step in understanding how to practice safe work around electricity. However, employees should be directed to contact local electrical utility companies if they are conducting any work or activity that might bring themselves, their equipment or anything they carry within 10 feet of a power line. Here’s a few tips for working around power lines.
You should always assume that power lines are energized. This includes lines on utility poles as well as those entering buildings. Always keep yourself, your equipment and anything you carry at least 10 feet away from power lines. Even if a power line has a covering, you should never assume it is safe to touch.
Avoid contact with powerlines when using high reach equipment. Keep all cranes, scaffolding, and high reach equipment away from power lines. Any contact with a power line can cause
serious injury or worse. Remember that you should try to keep a safe distance of 10 feet from all powerlines.
Call the utility company immediately should you find a downed power line. Again, you should always assume any power line is energized, even if it has fallen to the ground. Keep yourself and others away from any fallen power lines and call the utility company immediately to report the fallen line and its location.
Extension Cords
As mentioned above, extension cords are one of the most incorrectly used items in electrical work and deserves its own section on this page. Below are just a few
PRO TIP
While extension cords are invaluable on a construction site, they can create more harm than good. Ensure that the use of extension cords is not introducing new hazards to the work site such as electrical shock, fire and tripping hazards.
things employees should keep in mind when using extension cords.
■ Employees should only use extension cords that are the correct size and rating for the equipment in use. The diameter of the extension cord should be the same or greater than the cord of the equipment in use.
■ Employees should always inspect extension cords prior to use to ensure the insulation isn’t cut or damaged. Any cords that are damaged, become hot with use or

have wires exposed should be discarded. ■ Extension cords should only be used when necessary and on a temporary basis. Do not use extension cords as a
permanent solution for power.
■ Never unplug an extension cord by
pulling the cord; remove it by the plug.
First Aid
If you do find yourself in a situation where you, or a coworker, have been injured by an electrical shock, fire or electrocution, there are some important steps you should take to ensure the safety of the victim and those around the incident.
■ Call 911 with the address of the incident and inform them of the source of the incident. Do not hang up with the 911 operator until instructed to do so.
■ If possible, shut off the source to the electricity. If you cannot shut off the source of electricity, attempt to move the source away from both you and the injured person using a dry, nonconductive object made of cardboard, plastic or wood. Do this only if it does not place you at a risk of electrocution.
■ Cover any burned areas with a sterile gauze bandage, if available or a clean cloth. Don’t use a blanket or a towel as loose fibers can stick to burns.
Key Takeaways
■ Always assume that power lines are energized.
■ You, your equipment and anything you are carrying, should remain 10 feet away from power lines.
■ Extension cords should be inspected prior to use for damage or exposed wiring. ■ Choose extension cords that are
correctly rated for the equipment in use. ■ Ensure your safety and the safety of others should an injury occur due to
electrical work.
