What type of environment should workers avoid during a lightning storm?

During a lightning storm, workers should avoid open fields because these areas expose individuals to the highest risk during such weather events. Being in an open field can make a person the tallest object in the vicinity, increasing the likelihood of being struck by lightning. Lightning tends to strike the highest points in an area, so being in a wide-open space offers little protection.

In contrast, sheltered locations, such as indoors, provide safety from lightning. Vehicles can also serve as safe places during a storm, as they act as a Faraday cage, directing the electrical charge around the occupants rather than through them. Similarly, while large trees may offer temporary cover, they can attract lightning strikes themselves, and standing close to them poses an additional risk. Therefore, avoiding open fields is crucial for ensuring safety during lightning storms.
