Industrial Combustible Dust Cleaning

Combustible dust is any fine particulate — paper dust, wood dust, and other organic byproducts — that can ignite or explode when it accumulates. Federal standards classify accumulation of 1/16 inch or more as a fire and explosion hazard, which triggers mandatory cleanup requirements under NFPA 654.

It's required, not optional, for facilities that generate combustible dust. NFPA 654 sets the accumulation threshold, and OSHA's National Emphasis Program (CPL 03-00-008) actively targets facilities with visible dust buildup during inspections. This is a federal compliance issue, not a cleaning preference.

OSHA fines for combustible dust violations typically run $15,000–$150,000 per citation, with a per-violation minimum around $15,625. A single serious citation can cost more than a full remediation project — which is why most facility managers treat this as a proactive compliance issue rather than something to address after an inspection.

No — not legally or safely. Cleaning combustible dust in a Class II, Division 1, Group G environment requires CSA-certified, explosion-proof HEPA vacuums, OSHA 30-certified supervision, and LOTO (Lockout/Tagout) verification before work begins. Standard shop vacs and general-purpose equipment are prohibited in these environments.

Compressed air blow-downs are prohibited under NFPA 654. Blowing dust off a surface disperses it into the air, which is exactly the condition that creates an explosion risk. We use a 3-pass HEPA vacuum protocol instead — overhead structures first, then mid-level equipment and machinery surfaces, then floor-level accumulation.

CSA-certified, Class II Division 1, Group G explosion-proof HEPA vacuums — the specific equipment class required by law for this hazard classification. For overhead and high-ceiling work, we use articulating boom lifts (up to 40 ft) and scissor lifts operated by MEWP-certified staff, along with flame-resistant garments (NFPA 2113), respirators, and fall protection.

No. Our crew does not touch, contact, or disturb any active or energized equipment. Cleaning is performed on non-energized surfaces, overhead structures, walls, and floors only, and LOTO verification is confirmed before any work begins.

Both. We structure this work in two phases: an initial deep clean that brings a facility from heavy accumulation down to the OSHA/NFPA 1/16-inch compliance baseline, and ongoing maintenance — weekly or bi-weekly single-pass visits — that keeps it there. Facilities that have never been professionally remediated typically start with the initial deep clean.

The initial deep clean is priced based on square footage, ceiling height, number of rooms, and current accumulation level. Ongoing maintenance is quoted as a scheduled service contract. Every facility is different, so we provide a custom quote after understanding your space.

Any facility that generates paper dust, shredded paper waste, cellulosic particulates, or similar combustible byproducts — paper shredding and document destruction facilities, baling and recycling operations, print and paper manufacturing, and high-throughput warehouses. If OSHA or an insurance carrier has flagged dust accumulation at your site, this applies to you.

Yes. Ludlow Cleaning Co. carries workers' compensation and general liability insurance on every job, and every crew is led by an OSHA 30-certified supervisor with direct industrial hazmat cleaning experience.

We serve industrial facilities throughout El Dorado Hills, Folsom, Cameron Park, Roseville, Rancho Cordova, and Rocklin. For this service specifically, we regularly travel further than our standard residential/commercial coverage area — reach out with your facility's location and we'll confirm coverage.
