Immediate Actions When Lightning Strikes Nearby
During a lightning storm, move indoors immediately. The safest buildings are fully enclosed structures with wiring and plumbing, which help conduct lightning to the ground. Avoid open garages, covered patios, and tents. If you hear thunder, you are within striking distance, so seek shelter without delay. The National Weather Service provides real-time safety rules and updated guidance on lightning risks and shelter choices here.
Indoors, stay away from windows, doors, and concrete walls that may contain metal reinforcing bars. Do not use corded phones, plumbing fixtures, or appliances that connect to wall outlets during the storm. Unplug sensitive electronics before the storm arrives if possible. Use surge protectors and keep backup power systems, such as battery packs, charged in advance.
Safe Outdoor Locations and Structures
Hard-Topped Vehicles as Emergency Shelter
A hard-topped metal vehicle can serve as a safe shelter if no building is available. The metal shell directs lightning around occupants and into the ground, provided you do not touch metal parts inside. Keep windows fully closed and avoid leaning against doors or the frame during the storm.
Open fields, hilltops, tall isolated trees, and bodies of water increase lightning risk. If caught outside with no shelter nearby, avoid these areas. Crouch low with your feet together and minimize contact with the ground, but only as a last resort. Do not lie flat, and stay away from fences, power lines, and bodies of water.
Long-Term Planning and Infrastructure for Lightning Safety
Lightning Protection Systems in Buildings
Commercial and residential structures can use lightning rods, conductors, and grounding systems to direct strikes safely into the earth. The Lightning Protection Institute tracks certified installers and system standards, and its resources help property owners evaluate protection options here. Insurance carriers and risk engineers increasingly require documented protection for high-value assets and data centers.
Companies such as Tesla and SpaceX use robust grounding and surge protection in their facilities and launch sites to manage lightning-related risks. These systems are part of broader engineering standards that also apply to data centers, hospitals, and financial infrastructure. The U.S. Securities and Exchange Commission and other regulators highlight operational resilience, including protection from severe weather, in guidance for public companies here.
