Safety always starts with a simple click of the seat belt buckle.
With the advent of active safety systems in passenger vehicles, such as collision warning, blind spot, and rollover technology and the transition of these new technologies into emergency vehicles, the Fire Apparatus Manufacturers’ Association (FAMA) continues to drive safety and new technology to protect firefighters. While these new technologies help mitigate accidents, wearing your seat belt will always be the number one reason an individual can significantly reduce injury risk and increase his chance of survival in an accident.
Apparatus Seat Belt Evolution
Prior to the 1980s, both commercial and custom fire apparatus were equipped with lap belts, otherwise termed type 1 seat belts, and through the evolution of safety awareness and testing, we have transitioned into today’s three-point belts, otherwise called type 2 seat belts. Even today, a three-point seat belt is not mandated in a fire apparatus but has become the standard within our industry. The two seat belt types found in emergency vehicles are vehicle-structure-mounted seat belts and seat bels integrated with seats, or all belts to seat (ABTS). These two types are typically available through the fire apparatus manufacturers when specing your vehicle.
All of us know a seat belt secures an occupant in a vehicle. If you Google the definition of a “seat belt,” you will find it defined as “a belt or strap securing a person to prevent injury in vehicle or aircraft.” However, there is more to the restraint than just a simple belt or strap. A seat belt does several things, such as reducing contact within the interior of the apparatus, spreading the forces of the crash over a larger area of your body and preventing ejection from the cab. The seat belt also removes the possibility of you or your crew members becoming flying projectiles inside the cab and causing injury to others.
Vehicle Standards
The challenge to fire apparatus manufactures is that all seat belts in all vehicles must comply with the Federal Motor Vehicle Safety Standard (FMVSS), which is regulated and enforced by the National Highway Transportation Safety Administration (NHTSA). The regulation applying to seat belts is FMVSS 209, which specifies design, performance, and durability requirements. Fire apparatus are not exempt from this standard, and manufacturers are challenged with seating and space requirements. The standard also requires the seat belt fit a fifth-percentile female (108 pounds) to a 95th-percentile male (223 pounds). This applies to the occupants sitting in the seat but not including being outfitted in turnout gear.
The typical seat belt found in emergency vehicles is a three-point device consisting of a retractor, webbing, and a buckle. The retractor, which is inertia locking, is called an emergency locking retractor. The belt is a single piece of two-inch webbing that secures the occupant across the pelvic, chest, and shoulder area and has an FMVSS-rated tensile strength of 5,000 pounds. The retractor stores the webbing inside, which is attached to a spool that engages a coiled spring inside the retractor. The preset spring force allows the webbing to spool in and out of the retractor. The spring force itself keeps the belt firm against the occupant and eliminates any slack when worn. This design allows the seated occupants to move freely within the cab when belted and is activated only if an accident occurs. The typical retractor used in emergency vehicles is “dual sensitive,” wh
