Lightning Safety Talk
Lightning is a serious hazard both on and off the job. An average of 25 million lightning strikes occur in the United States each year. Individuals should identify and plan for the potential risk of lightning before beginning any work or leisure activity during storm season. Have a clear plan for when you will cease work and where you will go to find shelter if lightning is expected. The best practice to avoid being struck is to take shelter indoors before a storm reaches your immediate area.
Lightning Fatality Statistics
- Lightning kills approximately 20 people annually in the United States.
- Males account for a majority of these fatalities.
- Off-the-job activities that result in the most fatalities include fishing, beach activities, camping, boating, soccer, and golf.
- Most deaths occur during the months of June, July, and August.
- Many victims are on their way to safety at the time of the fatal strike.
Five Common Lightning Myths
Myth 1: If there are no clouds or rain, there will not be lightning.
Truth: Lightning can strike up to 3 miles from the center of a storm. In some cases, bolts have struck more than 10 miles away.
Myth 2: Lightning does not strike the same place twice.
Truth: Lightning often strikes the same place multiple times. Common targets include tall metal buildings, cell phone towers, and isolated trees in open areas.
Myth 3: Rubber tires on a car protect you from lightning by insulating you from the ground.
Truth: It is the metal frame of the vehicle that protects you. The frame conducts the electricity around you and into the ground, acting as a Faraday cage.
Myth 4: Take shelter under a tree during a thunderstorm.
Truth: Trees are often hit by lightning. Many injuries and fatalities occur when people are standing under or near trees during a lightning strike.
Myth 5: If you are in a house, you are 100% safe from lightning.
Truth: While a house is generally a safe place, you should avoid anything that conducts electricity. This includes corded phones, electrical appliances, wires, TV cables, computers, plumbing, metal doors, and windows.
Summary
It is essential not to become complacent about lightning safety. Although the total number of fatalities each year is relatively low, lightning strikes can be severe. According to Weather.gov, only 10% of those struck by lightning are killed, while the remaining 90% of victims are left with varying degrees of long-term disabilities.
