What is considered safe shelter from lightning?

An enclosed vehicle or a modern-built building is considered safe shelter from lightning due to their structural features that provide protection. Vehicles, particularly those with a metal frame, can act as a Faraday cage, which means that the metal body will divert electrical energy around the occupants inside, providing them safety during a lightning storm. Similarly, modern buildings are equipped with lightning protection systems and grounded electrical systems, which help to manage and dissipate electrical energy safely to the ground, further protecting individuals inside.

In contrast, options like an open field, a camping tent, and a tree do not offer any protection against lightning strikes. An open field exposes individuals to direct strikes, while a camping tent lacks the structural integrity needed for safe shelter during a storm. Standing under a tree is also dangerous, as trees can attract lightning, leading to potential injury or fatality from strikes, as well as secondary effects like falling branches. Therefore, the safety provided by enclosed vehicles or modern buildings is crucial in situations involving potential lightning strikes.
