One of the problems with open-air testing using explosives is that a high static charge or nearby lightning strike has the possibility of prematurely igniting the explosives. Sandia National Laboratories has developed a system (LEW-II) which takes data from a matrix of potential gradient sensors and rebroadcasts this information to test operators using explosives. By this method, the system gives early warning of possible hazards and allows safe storage of explosive materials. The LEW-II system and its use as a hazard warning and weather data collection system are described.
