Excerpts from FireRescue1.com:
NFPA 1901: Standard for Automotive Fire Apparatus – here are some of the most significant updates that have recently been introduced.
Chapter 4: General Requirements
One of the key additions is the requirement for vehicle data recorders, which can help improve driving and riding safety by capturing important operational data. Additionally, fire apparatus must now either have a calculated center of gravity not exceeding 80% of the vehicle’s height (as determined by tilt-table testing) or be equipped with a stability system (4.11 and 4.13). The contractor must also provide comprehensive documentation covering the entire apparatus and its major systems, including 20 detailed items to ensure both firefighters and mechanics have all necessary technical and practical information (4.20.2.3).The Fire Apparatus Manufacturers’ Association has also released a new “Fire Apparatus Safety Guide,†which outlines essential safety procedures for operating fire apparatus. This guide is item 20 in the document and covers hazards identified by FAMA safety signs, helping operators better understand the risks associated with the equipment.
A new exception statement now requires manufacturers to certify that the apparatus meets estimated in-service weight and stability requirements, linking maximum stop speed to GVWR, extinguishing agent tank capacity, or tire ratings. If certification isn't possible, a specific non-compliance statement must be provided, along with responsibility details (4.21).
Chapter 12: Chassis and Vehicle Components
New rules apply to diesel particulate filters installed on fire trucks, outlining their operation and performance standards (12.2.6.7).Chapter 14: Driving and Crew Areas
Seat belt length requirements have been updated, along with instructions on how to measure them properly. A new warning device is required to alert when an occupant is not wearing a seatbelt. Seat belts can now be orange in addition to red (14.1.3). For vehicles with a GVWR over 26,000 pounds, crew cabs must offer crash protection. Helmets are no longer allowed during vehicle movement due to interference with restraint systems, and proper storage must be ensured (14.1.7.4).Chapter 15: Body, Compartments, and Equipment Mounting
Retro-reflective striping on the rear of the vehicle is now required in a chevron pattern sloping downward at a 45-degree angle from the centerline (15.9.3.2).Chapter 16: Fire Pumps and Associated Equipment
Pumps rated over 3,000 gpm are now included in Chapter 16 alongside those under 3,000 gpm, with specific requirements based on their capacity. Gauges and flow meters must now be tested for accuracy during pump certification (16.14.3.2).Chapter 20: Foam-Proportioning Systems
Foam systems must now be type-tested for accuracy and certified by the manufacturer. After installation, they must also be tested and certified by the final installer (20.11).Chapter 22: Line Voltage Electrical Systems
This chapter has been reorganized with added clarity. Key changes include bonding the protective ground from a shoreline inlet to the vehicle frame, switching the neutral conductor through the transfer switch if multiple power sources are used, setting a minimum wire size for permanently mounted reels, and requiring fixed scene lighting devices to be tested and listed (22.7).Chapter 24: Air Systems
Training requirements for personnel using air systems have been added. Compressor compartments must have high-temperature alarms and labels warning against blocking airflow. Additional changes include: compressors must have air-quality monitoring systems; electric motor-driven compressors require a shoreline connection; and high-pressure air hoses and couplings must meet a 4-to-1 safety factor (24.1–24.3).Chapter 26: Trailers
A new chapter introduces requirements for trailers used in emergency response scenarios, with updates to address tow vehicle compatibility.Chapter 28: Ultra-High Pressure Pumps and Associated Equipment
This new chapter addresses the growing use of ultra-high pressure pumps, defined as those with a discharge pressure of 1,100 psi (7,600 kPa) or higher. It provides guidance for both manufacturers and buyers of these systems.
