Lightning Safety Awareness Week is June 22-28, 2014
Some workers are at greater risk than others
People who work outdoors in open spaces, on or near tall objects, with explosives, or with conductive materials such as metal have a large exposure to lightning risks. Workers in these occupations are among those with the most risk:
- Logging
- Explosives handling or storage
- Heavy equipment operation
- Plumbing and pipefitting
- Construction and building maintenance
- Farming and field labor
- Telecommunications field repair
- Power utility field repair
When thunderstorms threaten, don’t start anything you can’t quickly stop
Pay attention to the daily forecasts so you know what to expect during the day. Also pay attention to early signs of thunderstorms: high winds, dark clouds, rain, distant thunder or lightning. At this point, do not start any new task that you can’t quickly stop.
Know your company’s lightning safety warning program
Businesses that have high risk functions – such as explosives storage or field repairs during severe weather – should have a formal lightning warning policy that meets these two basic requirements:
- Lightning danger warnings can be issued in time for everyone to get to safe location
- Access to a safe place
Assess your lightning risk and take appropriate actions
During thunderstorms no place outside is safe. If you can hear thunder, lightning is close enough to strike. Stop what you are doing and seek safety in a substantial building or a hard-topped metal vehicle.
Know what objects and equipment to avoid during a thunderstorm
- Stay off and away from anything tall or high, including rooftops, scaffolding, utility poles and ladders
- Stay off and away from large equipment (e.g. bulldozers, cranes, backhoes, track loaders and tractors)
- Do not touch materials or surfaces that can conduct electricity (e.g. scaffolding, metal equipment, utility lines, water, water pipes and plumbing)
- Leave areas with explosives or munitions
If a co-worker is struck by lightning
Lightning victims do not carry an electrical charge, are safe to touch, and need urgent medical attention. Cardiac arrest is the immediate cause of death for those who die. Some deaths can be prevented if the victim receives the proper first aid immediately.
Call 9-1-1 and perform CPR if the person is unresponsive or not breathing.
Use an Automatic External Defibrillator if one is available.
