If lightning is moving toward a work site, what is a recommended safety precaution?

Seeking shelter inside a car is indeed a recognized and well-practiced safety precaution during lightning storms. When lightning strikes, a vehicle's metal body can provide a protective barrier. The electric charge is directed around the exterior of the vehicle and into the ground, keeping the occupants safe inside. Moreover, since the tires are made of rubber, which is a poor conductor of electricity, they also contribute to the safety of individuals within the car.

In contrast, getting to an open space and squatting low to the ground is not advisable since this position does not offer any protection. In fact, being in an open area increases the risk of lightning strikes, as tall objects like trees can attract lightning.

Climbing a tree significantly increases the risk of injury, as trees are often struck by lightning and being in close proximity to them can be extremely hazardous.

Holding a metal object is also dangerous since metal conducts electricity, which can lead to severe injury or fatality if a person is struck by lightning. Therefore, taking shelter in a car stands out as the safest and most effective precaution when lightning approaches a worksite.
