Final answer:
The NFPA standard for portable fire extinguishers is NFPA 10, covering their installation, inspection, maintenance, and testing. The NFPA 704 system is related but distinct, providing hazard information for chemical substances.
Step-by-step explanation:
The NFPA standard that refers to installation, inspection, maintenance, and testing for portable fire extinguishers is NFPA 10. This standard provides the guidelines to ensure that fire extinguishers are properly selected, placed, and remain ready for operation at all times. Within NFPA guidelines, safety equipment such as fire extinguishers should be easily accessible and well-maintained. The NFPA 704 Hazard Identification System is a different standard that describes the hazards of chemical substances and includes information such as flammability, reactivity, health hazards, and other special considerations on its hazard diamond.
Moreover, it is crucial to understand that the NFPA 10 standard requires that the selection and distribution of fire extinguishers should be appropriate for the specific risks present in the environment where they are installed. Regular inspection and maintenance are necessary to ensure they function correctly during an emergency. This also highlights the importance of awareness of lab safety protocols, including knowing the location of fire extinguishers and other safety equipment like eyewash stations.
