This service is great for improving air quality, prepping for painting, or removing debris that can cause defects or safety risks. It’s important to hire a contractor with the right training and experience in rafter and ceiling cleaning.
Combustible dust is fine material that can catch fire or explode when mixed with air. It comes from organic materials like flour, sugar, or wood, as well as some metals and nonmetallic substances.
Dust becomes dangerous when it accumulates on surfaces and is later disturbed, mixing with air and creating the potential for fire or explosion.
Dust can build up on rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment.
A dust explosion requires five elements: fuel, oxygen, an ignition source, dispersion of dust particles, and confinement—known as the “dust pentagon.”
The fire triangle includes fuel, oxygen, and ignition. The dust pentagon adds two more: dispersion and confinement.
