SIMPLIFIED CARDIOPULMONARY LIGHTNING PROTECTION GARMENT
A cardiopulmonary protective garment for providing limited protection from lightning is fabricated of a waterproof/breathable fabric, such as a Gore-Tex® laminate or equivalent. The garment keeps a wearer's body dry and supports a lightning flashover event when moist or wet on the outside, protecting the cardiopulmonary system. Strips of an electrically conductive fabric, such as Shieldex® or equivalent, can be attached in various arrangements on a posterior outer surface of the garment for igniting a rapid flashover. The conductive strips also provide attractive design details. In some embodiments, an inner heat shielding and flame resistant layer, made of a fabric such as NOMEX® or equivalent, can increase protection against burning caused by lightning and a flashover. Other embodiments may include a grounding strap electrically connected to the conductive strips for carrying charge to a local ground plane, such as the Earth; a cape-like drape of water-absorbing fabric having an electrically conductive element attached to a posterior side in general alignment with the wearer's spine; and a water-proof backpack having electrically conductive elements positioned to promote rapid flashover.
