Final answer:
NFPA 1901 is the standard requiring SCBAs to be secured by a mechanical latching device in fire apparatus, incorporating advances in technology from NASA's research.
Step-by-step explanation:
The National Fire Protection Association (NFPA®) Standard that requires seat-mounted SCBAs (self-contained breathing apparatus) to be held in place by a mechanical latching device is NFPA 1901, Standard for Automotive Fire Apparatus. This safety feature ensures that SCBAs remain secure and readily accessible to firefighters during emergency responses.
Such SCBA technology has evolved significantly over the years with contributions from NASA's research, resulting in lightweight systems using advanced materials, as well as enhancements in firefighter communication devices with rugged two-way radios and heat-resistant materials for firefighter suits.
