In a food processing facility, there are some hazards that can be easily spotted with the human eye: a color-coded tool in the wrong portion of the plant, a visibly-soiled food contact surface, a leaking/corroded hose, etc. However, there are a plethora of hidden and sometimes even invisible threats looming. One potentially fatal threat in food facilities that may linger out of sight is DUST.
NFPA 652 defines combustible dust as a “finely divided combustible particle solid that presents a flash fire hazard or explosion hazard when suspended in air of the process-specific oxidizing medium over a range of concentrations.” This applies to all facilities that manufacture, blend, package, repackage, convey, handle combustible dust, or particulate solids that may become dust.
When the following elements combine at the same time, there is risk of a dust explosion:
There are also some materials that become combustible only when in dust form. Keep in mind that after a first explosion, dust is dispersed into the air, which could result in a more deadly, secondary explosion.
Food product materials were responsible for a whopping 44.3% of fires and explosions. These numbers easily overshadow other materials like metal, coal, paper, plastic, carbon, etc. (24.1% is represented by the next most present material: wood products).
Even more troubling is that it's not easy to pin down just one or two culprits when examining materials in a food manufacturing plant. Instead, all materials need to be thought about holistically. As OSHA describes, “Any combustible material can burn rapidly when in a finely divided form. If such dust is suspended in the air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form.”
