Which standard requires diesel engines for reliability in ARFF vehicles?

• A. NFPA 414
• B. NFPA 402
• C. NIMS HP
• D. FEMA CEMP

Answer: (A)

The National Fire Protection Association (NFPA) 414 standard specifically addresses aircraft rescue and firefighting (ARFF) vehicles, including the requirements for their design, performance, and operational capabilities. One of the primary considerations outlined in this standard is the reliability and performance of the vehicles' engine systems.

Diesel engines are favored in ARFF vehicles for several reasons, primarily their power, durability, and ability to operate in extreme conditions without the same level of risk for overheating as gasoline engines. Given the critical role that ARFF vehicles play in ensuring safety and effective emergency response at airports, having a robust engine system is essential. NFPA 414 emphasizes that ARFF vehicles should be equipped with reliable and efficient power sources to maintain operational readiness during emergencies.

In contrast, the other options relate to different standards and guidelines. NFPA 402 is concerned with aviation emergencies and response procedures, NIMS HP refers to the National Incident Management System and its structure rather than specific equipment requirements, and FEMA CEMP focuses on emergency management protocols rather than vehicle specifications. Thus, while they all play vital roles in emergency operations and safety, they do not specifically mandate the use of diesel engines for reliability in ARFF vehicles the way NFPA 414 does.
