By definition, “a dry thunderstorm is a storm that has no or very little precipitation associated with it, but does carry electrical activity”. The absence of precipitation can create a false sense of security that poses a serious risk to the safety of people and structures. In this scenario, a system with sensors capable of detecting all phases of the storm and issuing warnings before the first impact can make a difference.
The Occupational Safety and Health Administration (OSHA) of United States details in its report on “safety in the construction industry” that precautions should be taken to avoid the danger of lightning to workers.
