GVWR SUBSTANTIATION: The justification for adding an additional chapter (6810 kg to 9080 kg) stems from the increasing percentage of “Rescue Pumpers” being utilized (6801 kg to 9000 kg) by the fire service, as they adapt their equipment to new and more varied roles. The increased EMS, Rescue, and Haz-mat roles are forcing many 20,001 lb and up departments to combine these functions into vehicles also serving the (9080 kg and up) traditional pumper role. This is resulting in over weight vehicles when all of 20,001 lb - 30,000 lb 3000 lb (1,350 1360 kg) the additional equipment for these functions is added to vehicles designed for GVWR normal pumper service.

The tiller driving compartment roof is normally the highest point on the vehicle.

A.12.3.1.5 Adequate braking capacity is essential for the safe operation of fire apparatus. While this subject is normally covered in state highway regulations, it should be noted that fire apparatus might have a special problem as compared with normal vehicles of the same gross vehicle weight. Fire apparatus could be required to make successive brake applications in a short period of time when attempting to respond to alarms with minimum loss of time. Thus, the problem of brake “fade” and braking capacity could be critical unless the brakes provided take into account the service requirements. Air actuated brakes are recommended for fire service vehicles of over 25,000 lb (11,000 kg) GVWR. �

Significant changes to the 1991 edition included requiring total enclosure Annex E Informational References of driving and crew areas, limiting the maximum stepping height, requiring access handrails, and requiring additional warning lights and reflective striping. The minimum pump size for a fire pump on a pumper was raised to E.1 Referenced Publications. The following documents or portions thereof 750 gpm, and the minimum water tank size was set at 500 gal. The documents are referenced within this standard for informational purposes only and also addressed line voltage electrical systems and foam systems for the first are thus not part of the requirements of this document unless also listed in time. Chapter 2. The test and delivery data requirements were updated to ensure that more E.1.1 NFPA Publications. National Fire Protection Association, 1 of the performance requirements of the standards were tested as part of Batterymarch Park, P.O. Box 9101, Quincy, MA 02269-9101. the delivery process and that proper documentation was provided to the purchaser. Appendix A was expanded to provide more discussion of the NFPA 11, Standard for Low-Expansion Foam, 2002 edition. requirements in the standard, and a new appendix was added to provide NFPA 70, National Electrical Code®, 2002 edition. a form that a purchaser could use to define the information needed by the contractor to properly design, build, and deliver the fire apparatus. NFPA 70B, Recommended Practice for Electrical Equipment Maintenance, 2002 edition. Recognizing that much apparatus is multifunctional and that the process of maintaining separate documents for the traditional types of fire apparatus did NFPA 1150, Standard on Fire-Fighting Foam Chemicals for Class A Fuels not always address the need for nontraditional types or use of fire apparatus, in Rural, Suburban, and Vegetated Areas, 1999 edition. the committee combined the four documents back into a single fire apparatus standard for the 1996 edition and organized the standard to cover not only the NFPA 1906, Standard for Wildland Fire Apparatus, 2001 edition. traditional types of fire apparatus but also multifunctional and nontraditional use apparatus. New chapters were added to cover compressed air foam NFPA 1911, Standard for Service Tests of Fire Pump Systems on Fire systems, air systems,DRAFT command and communication areas, and winches. Apparatus, 2002 edition. Many requirements were added throughout the document to improve the NFPA 1912, Standard for Fire Apparatus Refurbishing, 2001 edition. safety for fire fighters using the apparatus. These requirements included NFPA 1931, Standard on Design of and Design Verification Tests for Fire limiting the height of controls to 72 in. (2 m) above the standing position of Department Ground Ladders, 1999 edition. the operator, requiring equipment in driving and crew areas to be securely fastened or in a compartment, increasing work lighting around the apparatus, NFPA 1981, Standard on Open-Circuit Self-Contained Breathing and better grouping of pump controls to keep the operator away from the Apparatus for Fire and Emergency Services, 2002 edition. intake and discharge outlets. The low voltage electrical chapter was totally rewritten to require load analysis and load management if the total connected NFPA 1983, Standard on Fire Service Life Safety Rope and System load cannot be supplied by the vehicle’s alternator. The requirements for Components, 1995 edition. warning lights were also rewritten to provide for different lighting when “calling for right-of-way” versus “blocking right-of-way.” Requirements for NFPA 1991, Standard on Vapor-Protective Ensembles for Hazardous warning lights were increased to provide more visibility of the fire apparatus. Materials Emergencies, 2000 edition. New requirements were added for powered equipment racks, SCBA and NFPA 1992, Standard on Liquid Splash-Protective Ensembles and Clothing cylinder storage, pump and plumbing access, and slip-on fire-fighting for Hazardous Materials Emergencies, 2000 edition. modules. The baffling requirements for water tanks were changed to allow for Fire Protection Guide to Hazardous Materials, 12th edition, 1997. either containment or dynamic baffling to be used. As a fundamental change in the aerial device chapter, water towers were redefined as aerial devices with E.1.2 Other Publications. elevated stream capability only. If water towers have a ladder on them, they are considered aerial ladders. Requirements were also added for secondary E.1.2.1 Association of American Railroads Publication.
