Firefighters, police, and EMTs are typically first on the scene in an emergency and face the greatest risk from electrical contacts and fires. Understanding the potential dangers and learning how to deal with them correctly makes everyone safer.
Assume all lines are energized and potentially dangerous.
Keep personnel and equipment at least 10 feet from overhead lines at all times. Consider how close aerial equipment will be when fully extended, and use a spotter to monitor placement.
OSHA requires greater than 10 feet of clearance from lines that are over 50,000 volts. For example, the minimum clearance for a 500,000-volt line is 18 feet. There are no visible markers to identify a power line’s voltage, so call the local electric utility for clearance information if you are unsure.
Secure the area. Keep yourself and the public at least 100 feet away from fallen power lines. Fallen transmission lines from large towers require 100 feet of clearance.
Stay clear of all downed lines and anything they are contacting, including nearby fences, trees, cable or phone lines, and the ground.
Be extremely cautious when using water to fight fires near downed power lines. If you must use water, use only a mist or spray. Do not use a stream—it can create a clear path for current.
Do not enter or contact vehicles that may be energized. Instead, instruct victims to drive the vehicle away from the line if they can do so safely.
If the vehicle cannot be safely moved, instruct victims to stay put until utility personnel give the all clear.
If victims are in imminent danger from fire or other hazards, stay away, and instruct them to jump clear without touching the vehicle and the ground at the same time. They must land with their feet together and shuffle away with small steps.
If victims are injured, disabled, or otherwise unable to safely exit the vehicle, your incident commander will tell you how to proceed.
Let it burn. Burning electrical equipment is already ruined and will be replaced. Contact the local utility and wait for them to arrive.
Evacuate the area. Keep people at least 300 feet away. Protect exposures to prevent fire from spreading.
If an equipment fire must be suppressed, utility personnel and your incident commander will tell you how to proceed.
