NFPA 704 safety squares on containers of ethyl alcohol and acetone. "NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association.
Tests can be bench scale (e.g., flammable liquid flash point), medium scale (e.g., storage commodity classification), or full scale (e.g., replication of an entire rack storage configuration). [7] Typical information gathered from full-scale testing is heat release rate vs. time, smoke production and species composition, radiant heat, and ...
By measuring the oxygen consumed during combustion, one could estimate heat release of a fire; this method is now termed oxygen consumption calorimetry. [5] This finding was a rediscovery of a method first identified in 1917 by W. M. Thornston, whose research similarly found that during combustion of organic liquids and gases , a consistent ...
Haines Index (also known as the Lower Atmosphere Severity Index) is a weather index developed by meteorologist Donald Haines in 1988 that measures the potential for dry, unstable air to contribute to the development of large or erratic wildland fires. [1]
A red flag warning (issued by the National Weather Service when low relative humidity and high winds and temperatures are expected) will generally precede any fire activity by at least one to two days. A fire warning will generally include information on the location and movement of the fire, evacuation instructions, and shelter locations.

Rate-of-Rise (ROR) heat detectors operate on a rapid rise in element temperature of 6.7 to 8.3°C (12.1 to 14.9°F) increase per minute, irrespective of the starting temperature. This type of heat detector can operate at a lower temperature fire condition than would be possible if the threshold were fixed.
