Do you manufacture or use any materials (and their by-products) that can become a dust?.

the likelihood there will be an illness, injury or death in a hazardous situation resulting from a combustible dust flash fire or explosionīest practice is to keep the workplace as dust free as possible.īelow are some questions that may help.

the presence of ignition sources (e.g., hot surfaces, flames, friction points, sparks, electrostatic discharges, etc.).

the likelihood (probability and degree) the dust will be a flash fire or explosion hazard.

if there are processes to prevent the dust from accumulating.

are there processes that cause dust to enter the air or create dust clouds.

the areas where combustible dust accumulates (e.g., visible or hidden – equipment, beams, pipes, etc.).

the sources of combustible dust (e.g., the materials and processes used in the manufacturing methods).

A risk assessment is a process that determines: In order to determine the level of risk from combustible dust, a risk assessment should be completed by a competent person (e.g., safety engineer, industrial/occupational hygienist, etc.). As a result, the often quoted "rule of thumb" about dust accumulation (such as being able to write in the dust, or the dust being the thickness of a paperclip, dime or quarter, or the amount of visibility through a dust cloud) is not always reliable. There are many variables that must be considered - the particle size of the dust, the method of dispersion, ventilation system characteristics, air currents, ignition sources, confinement of the dust cloud, physical barriers, and so on.

What are examples of materials that can be a combustible dust hazard? The National Fire Protection Agency (NFPA) defines combustible dust as “a finely divided combustible particulate solid that presents a flash-fire hazard or explosion hazard when suspended in air or the process-specific oxidizing medium over a range of concentrations” in Standard 652-2019, The Fundamentals of Combustible Dust. The Occupational Safety and Health Administration (OSHA) in the United States defines combustible dust as "a solid material composed of distinct particles or pieces, regardless of size, shape, or chemical composition, which presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations".

For example, the Hazardous Products Regulation (for Workplace Hazardous Materials Information System (WHMIS) 2015) defines combustible dust as " a mixture or substance that is in the form of finely divided solid particles that, upon ignition, is liable to catch fire or explode when dispersed in air".Īnother example is Alberta's Occupational Health and Safety Code which defines combustible dust as "a dust that can create an explosive atmosphere when it is suspended in air in ignitable concentrations". The technical definitions for combustible dust vary. What is the technical definition for combustible dust?

The build-up of even a very small amount of dust can cause serious damage. When the dust is disturbed and under certain circumstances, there is the potential for a serious explosion to occur. Dust can collect on surfaces such as rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment. Therefore any activity that creates dust should be investigated to see if there is a risk of that dust being combustible. Some of these materials are not "normally" combustible, but they can burn or explode if the particles are the right size and in the right concentration. carbonaceous materials (e.g., charcoal, soot).most solid organic materials (such as sugar, flour, grain, wood, etc.).Combustible dust may include materials that are in the physical states of powders, flakes, fines, fibers, etc. A combustible dust is any material (finely divided solid particles) that has the ability disperse in air and catch fire and explode when exposed to an ignition source.
