Remtech specializes in combustible dust cleaning and hazard analysis and prevention audits for manufacturing and facilities producing, aerospace components, chemicals, carpets, textiles, food, sugar, forestry and furniture products, processing wastewater, metal processing, paper products, pharmaceuticals, and recycling operations (metal, paper, food products, synthetics, and plastics).  

Remtech's professionals are trained in the removal of fine dust particulates that can accumulate and cause potential fire or explosion hazards.  Remtech's specialized cleaning techniques ensure compliance with Insurance company requirements that require compliance with OSHA 's Directive #: CPL 03-00-008 Combustible Dust National Emphasis Program and NFPA 484, 654 Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids.  

NFPA 652, the National Fire Protection Association’s Standard on the Fundamentals of Combustible Dust. First issued in 2016 and updated for 2019, NFPA 652 sets the requirements used by OSHA and other authorities having jurisdiction (AHJs) to determine if companies are doing what they need to do to keep their workers safe from combustible dust hazards. Under NFPA 652, all facilities with combustible dust hazards must have a Dust Hazard Analysis ("DHA") completed by a professional safety consultant by September 7, 2020.

Combustible Dust Hazard Analysis & Prevention Audits:

◆ Combustible dust, ignition, dispersal, and confinement source controls

◆ Combustible dust management and controls  

◆ Friction, electrical, open flame, and static ignition controls

◆ Fire suppression and prevention systems

Remtech's Specialized Combustible Dust Cleaning Equipment includes:

◆ High lift and elevated scaffolding with fall protection and personal protection

◆ Static controlled HEPA vacuum truck particulate removal

◆ Grounded and Bonded Explosion Proof HEPA vacuum cleaning

◆ Oil and Water Immersion Explosion Proof Vacuum Cleaning of Metal Dusts

◆ Pressure Washing

◆ HEPA air cleaning, negative pressure, and exhaust systems

◆ Wet cleaning floor scrubbers

Combustible dusts that provide fuel for fires or explosions are frequently organic or metal dusts that are finely ground into very small particles, fibers, fines, chips, chunks, flakes, or a small mixtures. Types of dusts include, metal dust, such as aluminum and magnesium; wood dust; plastic dust; biosolids; organic dust, such as sugar, paper, soap, and dried blood; and dusts from certain textiles.

Five Conditions are Required for a Dust Explosion:

◆ combustible dust fuel is present

◆ dust suspended/dispersed in air at high concentrations

◆ oxidant is present

◆ ignition source is present

◆ area is confined or enclosed in a building

Sources of Dust Ignition Include:

◆ electrostatic discharge

◆ mechanical sparks/friction

◆ electrical arcing

◆ electrical motors/contacts

◆ hot surfaces

◆ fire or open flames from welding

◆ auto ignition

Combustible dust cleaning removes the fuel for fire and explosions.  Remtech uses static controlled and grounded, and dust suppression systems to ensure that combustible dusts are removed safely.
