In 2005, on a vehicle accident we had an Engine company operating on the shoulder of a busy highway at about 0100 in the morning. A drunk driver collided with the side and the front door of the apparatus, then struck the vehicle involved in the accident slamming it into the ambulance which the crew had just loaded the two patients into. A near miss as fire personnel were able to get out of the way, but the Medic on the transport unit received a serious head injury which kept him off work for several months.
Since that time we have added the following procedures. For any highway incident, the ALS engine is followed by an aerial ladder, and Battalion Chief. The aerial provides a portable safety barrier for the crew from the engine to operate safely and the Battalion acts as the safety officer to watch for all hazards. Additionally we now require that ALL PERSONNEL operating on any call on surface and highway roadways to wear an ANSI Class III vest over what ever PPE they are required to wear. The only exception is if you are in an SCBA and in an IDLH then you do not have to wear the vest. Additionally we now have large chevrons applied to the rear ladder compartment of the Truck Company to provide a higher visibility.
