True or False? NFPA 1901 requires the parking brake to hold the apparatus on a 10 percent grade.

The statement regarding NFPA 1901 requiring the parking brake to hold the apparatus on a 10 percent grade is false. NFPA 1901, which pertains to automotive fire apparatus, does not specify that the parking brake must be able to hold the apparatus on a 10 percent grade. Instead, these standards focus more on the overall operational safety and performance of fire apparatus, including brake system performance under varied conditions but do not enforce specific grade requirements.

The requirement is actually for parking brake systems to be sufficiently effective to hold the vehicle in place when parked, which generally might include various scenarios but does not limit it to a specific grade like 10 percent. Thus, this aligns with the understanding that the braking systems must meet certain performance criteria without attributing those criteria to specific grade levels. This highlights a broader commitment to safety rather than a literal application of stopping power on inclined surfaces.
