An air horn provides a loud, attention-grabbing signal that can alert rescuers or warn others during power outages, fires, storms, or natural disasters.
The sound of an air horn is more typically associated with being alerted to a warning or someone being in distress, unlike a whistle or an electronic buzzer.
This is particularly important on construction sites, for construction safety, emergency safety stations, industrial safety and signaling, crane safety, drilling and blasting, mining and quarrying, railway track maintenance crews, road flagging crews, and more.
