Sawdust Cannon

From Navy Island, Inc., a MN manufacturer of veneers and doors. Excellent example of a controlled wood dust explosion. Notice how the flame front moves through the suspended dust. This is a perfect example how a flame front will travel in a primary or secondary explosion. Click on the link to see the original:

The Fire Triangle, Fire Tetrahedron and Dust Explosion Pentagon

Fire Triangle From Wikipedia, the free encyclopedia Jump to: navigation , search The fire triangle. The fire triangle or combustion triangle is a simple model for understanding the ingredients necessary for most fires . [1] 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 t

Are Spices Flammable?

Is Cinnamon Flammable? - Science - ChefSteps Made from the dried bark of Cinnamomum verum , a tree indigenous to Sri Lanka, cinnamon's exotic perfume and subtle flavor come from its two major components: cinnamaldehyde and eugenol. These two chemicals are volatile, meaning they readily vaporize at temperatures comfortable to humans, which is in fact why cinnamon is so fragrant. But those same vapors are also highly combustible (indeed, combustion only happens in the presence of vapors), making cinnamon a highly flammable material under the right conditions. Now a cloud of cinnamon dust isn’t the kind of thing most people would consider dangerous, but add enough heat and you’ll quickly have an expanding ball of fire known as a dust explosion. For dealing with this situation, we can only recommend a good pair of running shoes. In fact, the federal Occupational Safety and Health Administration issues warnings about cinnamon explosions in food manufacturing plants.

Functional Safety Audit vs. Functional Safety Assessment

From Chemical Processing Don’t Confuse a Functional Safety Audit with a Functional Safety Assessment Understand the critical differences between the two essential evaluations By John Walkington, ABB Safety Lead Competency Centre Apr 19, 2017 Many people working in safety instrumented system (SIS) project development, execution, operation and maintenance treat a functional safety audit (FS Audit) and a functional safety assessment (FSA) as one and the same. So, based on this assumption, they simply ensure that such an activity is undertaken and perhaps signify the need to perform this evaluation at some point when it appears as a milestone on the project schedule. Moreover, often they call upon someone working on the project, who may or may not have had some previous experience in quality auditing, to deliver this audit/assessment. However, this is not a reasonable approach because the concepts for the audit and assessment markedly differ. An FS Audit provides
