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]
As live fuels cure and dead fuels dry, the ERC values get higher, thus providing a good reflection of drought conditions. The scale is open-ended or unlimited and, as with other NFDRS components, is relative. Conditions producing an ERC value of 24 represent a potential heat release twice that of conditions resulting in an ERC value of 12.
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.
Components and systems subject to certification fire testing include fire rated walls and floors, closures within them such as windows, fire doors, fire dampers, structural steel, and fire stops. Fire tests are conducted both on active fire protection and on passive fire protection items. There are full-scale, small-scale and bench-scale tests.
With the Fourth of July holiday coinciding with the heat wave, state fire officials also said people should be especially careful with setting off fireworks, in light of particularly fire-prone ...
Heat can be removed by the application of a substance which reduces the amount of heat available to the fire reaction. This is often water, which absorbs heat for phase change from water to steam. Introducing sufficient quantities and types of powder or gas in the flame reduces the amount of heat available for the fire reaction in the same manner.
Fire blankets aim to make putting out small fires as simple as possible. The SecuCaptain is made of flame-retardant fiberglass fabric that withstands temperatures up to 1,076°F, ...
