The term inerting is often loosely used for any application involving an inert gas, not conforming with the technical definitions in NFPA standards. For example, marine tankers carrying low-flash products like crude oil, naphtha, or gasoline have inerting systems on board. During the voyage, the vapor pressure of these liquids is so high, that ...
In 2024, the Grenfell Tower Inquiry's final Phase 2 report noted that the NFPA's prescriptive approach to drafting its standards "reflects a conservative approach to fire safety which is embedded in North American culture" and the NFPA standards "allow little scope for independent design choices".

The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States. [according to whom?] It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined experimentally, referred to as flammability limits or explosive limits.
NFPA 921, "Guide for Fire and Explosion Investigations", is a peer reviewed document that is published by the National Fire Protection Association (NFPA). Its purpose is "to establish guidelines and recommendations for the safe and systematic investigation or analysis of fire and explosion incidents" (section 1.2.1).
In December 2011, Halotron I underwent testing for "hidden fire" suppression, inspired by the demonstrated effectiveness of Halon 1211 in controlling an in-flight fire aboard a Delta L-1011 on March 17, 1991.
