Fire TriangleFrom Wikipedia, the free encyclopediaJump to: navigation, search The fire triangle. The fire triangle or combustion triangle is a simple model for understanding the ingredients necessary for most fires. It has been replaced in the fire fighting and protection industry partially by the fire tetrahedron (see below).
The triangle illustrates a fire requires three elements: heat, fuel, and an oxidizing agent (usually oxygen). The fire is prevented or extinguished by removing any one of them. A fire naturally occurs when the elements are combined in the right mixture. Without sufficient heat, a fire cannot begin, and it cannot continue. 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 requires 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 …
Being involved in helping protect the wood products industries from fires and explosions for the last 3 decades, we have seen first hand the results of many of these types of fires - and the lack of understanding of causes of combustible dust related fires. As such a complex subject, it is not often someone from the press understands and reports accurately on the causes of industrial combustible dust related fires. This is a fine article from Gordon Hoekstra at the Vancouver Sun. It also shines a light on the need for stakeholders to understand the combustible dust problem in these mills, as well as the solutions - efficient dust collection and storage, spark detection, fire suppression, explosion protection, housekeeping etc.

NFPA Introduces NFPA 652 Combustible Dust Standard July 27, 2015
Every year, destructive and deadly dust-related fires and explosions affect a wide range of industries around the world. In the United States alone, 50 combustible dust accidents occurred between 2008
and 2012. To manage the dust-related fire, flash fire, and explosion hazards in industries that use dust collection and handling equipment, or have processes that may generate combustible dust, the National Fire Protection Association (NFPA) introduces the first-time NFPA 652: Standard on the Fundamentals of Combustible Dust.
This important new Standard serves a wide variety of industries including chemical, wood processing, metals, and agricultural.
In addition to providing new general requirements for managing combustible dust fire and explosion hazards, NFPA 652 directs users to NFPA's appropriate industry- or commodity-specific standards, such as NFPA 61: Prevention of Fires and Dust Explosi…
