Lightning Safety When Working Outdoors
www.osha.govsystems cannot predict the first lightning strike. Consequently, it is important to watch the sky for storms developing overhead or nearby and get to a safe place prior to the first lightning strike. Portable and hand-held lightning detectors function by detecting the electromagnetic signal from a nearby lightning strike and then

Broadly speaking, low frequency effects operate only by electrical conduction, whereas high-frequency effects may be induced and operate at a distance without a physical connection.
