The variety of transportation means used in industrial tracks (railways, road vehicles, etc.) transforms personal safety into a complex task to be achieved. Confusion and higher levels of environmental noise significantly restrict the possibility of perception from staffs, and the risk of accidents reaches intolerable numbers. As shown by risk analysis the risk of accidents could be significantly reduced by using a personal warning system. The active optic and acoustic alarm from Schweizer Electronic AG’s personal warning system provides a safer and more efficient indication of risks to the staff.
