3. Combustible Dust Basics
Combustible Dust: Any finely divided solid material that is
420 microns or smaller in diameter and presents a fire or
explosion hazard when dispersed and ignited in air.
In addition to the familiar fire triangle of oxygen, heat, and
fuel (the dust), dispersion of dust particles in sufficient
quantity and concentration can cause rapid combustion
known as a deflagration.
If the event is confined by an enclosure such as a building,
room, vessel, or process equipment, the resulting pressure
rise may cause an explosion.
These five factors (oxygen, heat, fuel, dispersion, and
confinement) are known as the “Dust Explosion Pentagon.”
If one element of the pentagon is missing, an explosion
cannot occur.

4. Significant Events
• In 1999, a primary explosion of natural gas in an idle power boiler followed by a secondary explosion of
disturbed coal dust in the facility caused six fatalities and 14 serious injuries in a Michigan electrical
power generation facility.
• In May 2002, an explosion occurred at Rouse Polymerics International, Inc., a rubber fabricating plant,
in Vicksburg, Mississippi, which injured 11 employees, five of whom later died of severe burns. The
explosion occurred when highly combustible rubber dust ignited.
• On January 29, 2003, an explosion and fire destroyed the West Pharmaceutical Services plant in
Kinston, North Carolina, causing six deaths, dozens of injuries, and hundreds of job losses. The facility
produced rubber stoppers and other products for medical use. The fuel for the explosion was a fine
plastic powder, which accumulated above a suspended ceiling over a manufacturing area.
• These and other explosions — in Georgia, Michigan, Kentucky, and Indiana — resulted in the loss of 25
lives and caused numerous injuries and substantial property damage.

5. Regulations
• Most utilities began mitigation of combustible dust to address insurers’ requirements
• In many cases the utility had the choice of implementing the insurers’ requirements or paying a policy
premium
• As industry events involving explosions or significant fires began to be recognized as combustible-dust-
related, the requirements quickly evolved
• On June 14, 2007, federal OSHA issued a draft compliance directive, Combustible Dust National
Emphasis Program
• One variable was guidance in the NEP for assessing the extent of condition
o Dust Accumulations: Annex D of NFPA 654 contains guidance on dust layer characterization and
precautions. It indicates that immediate cleaning is warranted whenever a dust layer of 1/32-inch
thickness accumulates over a surface area of at least 5% of the floor area of the facility or any
given room. The 5% factor should not be used if the floor area exceeds 20,000 square feet, in
which case a 1,000 square foot layer of dust is the upper limit.
• The next year most state OSHA plans adopted NEP’s recommendations and began enforcement visits

6. OSHA Recommendations
• Minimize the escape of dust from process equipment or ventilation systems
• Use dust collection systems and filters
• Utilize surfaces that minimize dust accumulation and facilitate cleaning
• Provide access to all hidden areas to permit inspection
• Inspect for dust residues in open and hidden areas, at regular intervals
• Clean dust residues at regular intervals
• Use cleaning methods that do not generate dust clouds if ignition sources are present
• Use vacuum cleaning equipment approved for dust collection (grounded equipment)
• Locate relief valves away from dust hazard areas
• Develop and implement a hazardous dust inspection, testing, housekeeping and control
program (preferably in writing with established industrial cleaning provider that will provide
frequency and methods

7. Foam Cleaning
With virtually limitless applications, foam cleaning can remove combustible and
non-combustible dust, dirt, oil, grease and more. MPW’s foam cleaning helps
eliminate fire hazards by using non-flammable chemicals.
• 100 percent biodegradable
• Non-flammable
• Non-corrosive, neutral pH and
environmentally friendly
• Adjustable between “wet and dry” foam
• Increased “hang time” allows more
contact with surface areas
• High-expansion foam provides
maximum coverage with minimal
moisture addition
• Decreases safety-related incidents
• Lack of irritating or harmful odors
yield a safer work area
• Fewer man hours dedicated to
scrubbing, power washing or
rinsing
• Prevents or shortens shutdowns
• Custom-made to meet your specific
needs

8. Mormar Coaltrol F430
Low-foaming residual dust-control additive
• Binds dust fines together, reducing fugitive dust emissions
• The low-moisture foam properties reduce the risk of shorting out electrical
components during on-line facility cleaning applications
• Anti-static properties dissipate electrostatic energy on treated surfaces and anti-
oxidant properties scavenge free radicals to help prevent the conditions that lead
to explosions in coal dust areas
• Unique cationic surfactant chemistry attracts negatively charged coal dust
particles, improving cleaning and dust reduction

9. Vacuuming Services
MPW’s dry and wet vacuum cleaning solutions manage the safe removal, transport and
disposal of nonhazardous wastes from job sites, including remote or inaccessible areas. Our
fleet consists of Transport tankers, Supersuckers and dry and wet maxi TurboVacs. Many
units are equipped with the latest SCR technology, allowing our trucks to operate in enclosed
facilities without the accumulation of exhaust within the building.
• Payload capacity of 18 cubic
yards
• Positive displacement vacuum
pumps providing 5,000-6,000
CFM of airflow
• Static ground cable
• Temperature gauges inside and
outside for continuous
monitoring
• Decreases safety-related
incidents
• High-powered airflow
solution to pick up the
toughest solids and liquids
• Single-mode filtration
enables loading of wet or
dry materials with no
changeover

10. NewsonGale Earth-Rite MGV
Vacuum trucks and tank trucks, including their hoses and hose connections, are
susceptible to static charge accumulation during the transfer of product into or out
of the truck’s containment system. This accumulation of static charge is equivalent
to a hidden source of ignition and if discharged as a static spark can lead to the
ignition of the product or the atmosphere in which the truck and material handling
team is operating.

11. NewsonGale Earth-Rite MGV
• The Earth-Rite MGV automatically verifies if the truck is connected to a
ground source that is connected to the mass of the earth
• It will monitor the resistance between the verified ground source and the truck
so that if exceeds 10 ohms the green LED indicators will switch form pulsing
green to red
• Internal dry contacts can be utilized to shut down the movement of liquid or
powder if the Earth-Rite MGV detects that ground connection is not present
• Site electricians do not need to perform a one-time check with a meter. The
Earth-Rite MGV will not only perform this check automatically for the driver, it
will continue to monitor the connection for the duration of the transfer
operation

12. Superproducts

13. Goodway Industrial Vacuum HEPA
• Grounding cable
• Anti-static filter
• External filter shaker
• 9-gallon non-sparking stainless
steel detachable tank with
handles, casters and a tool basket
FeaturesThe DV-AV9-EX explosion-proof vacuum
includes industrial power with HEPA filtering
and UL certification for use where explosive and
hazardous materials are present like fine
powders, coal dust, flammable dust and more.
Powered by compressed air, this industrial
vacuum is capable of dry pickup including
filtering to 99.99% down to .03 microns. It also
includes an external shaker to make sure it
keeps filters clear of clogs.

14. Cable Trays
Custom-designed and fabricated by MPW’s engineering team, the cable tray
system eliminates combustible dust by mixing medium air pressure with high
vacuum pressure in the nozzle inlet. This removes the dust and debris from
between the cables and through the nozzle outlet, ensuring that little to no
airborne dust escapes the area. This procedure is safe for use on live wires.

15. Case Study
MPW conquers 30 years of coal residue at Virginia plant
• A Virginia manufacturing facility needed to eliminate coal ash and dust that had accumulated for 30 years
• The plant was decommissioning its coal-fired power source in favor of natural gas, so it needed the area to
be like new
• The facility had never had the area professionally cleaned to this standard in the past
• The scope of the project included a boiler, a power house, precipitators and coal silos
Problem
Solution
• MPW utilized high-tech Supersucker Vacuum Trucks for the majority of the project
• Coal storage and other aspects of the cleaning were best suited to MPW’s foam cleaning services, which are
ideal for the removal of combustible and non-combustible dust, dirt, oil, grease and more. Foam cleaning also
helps eliminate fire hazards by using non-flammable chemicals.
• MPW used three to four vac trucks — each with an 18-cubic-yard payload capacity — and up to 35
technicians per day and made sure its own Operations Managers and Health and Safety officials were on site
daily to keep the operation running smoothly and safely.

16. Case Study
MPW conquers 30 years of coal residue at Virginia plant
Results
• The project, which lasted nearly four months, was executed
seamlessly.
• MPW worked 25,751 man-hours with zero lost-time injuries, zero
safety issues and zero OSHA-recordable incidents.
• Ecstatic with the quality of the clean, plant managers
communicated to MPW representatives that the venue had never
looked that great.
• On a Job Performance Evaluation, the facility’s construction
manager graded MPW “Very Satisfied” on five key performance
categories, writing: “Overall project was very successful and I
would absolutely use MPW again!!”
