2. Air Quality Standards
and Regulations
Ensuring dust collection equipment
is designed and maintained in proper
operating condition is essential
to complying with EPA and OSHA
regulations and NFPA standards.

3. Why Is
Compliance Essential?
•Helps ensure facility protection and worker safety
•Sound environmental stewardship
•Avoid monetary fines or being shut down due to
non-compliance
•Ensures company reputation with customers,
consumer and business partners

4. Regulatory/Standards
Setting Bodies
•Environmental Protection Agency (EPA)
•Occupational Safety and Health Administration (OSHA)
•National Fire Protection Association (NFPA)

5. EPA
•Develops and enforces regulations designed for worker, public
and environmental protection
•EPA operating permits (issued at the local/state level) specify the
acceptable level of outlet emissions from a dust collection system.
•The EPA regulates the environmental impact of dust collection,
including setting standards for the emission of fine particulate
matter (PM2.5).
•The PM2.5
standard measures airborne dust particles that are
2.5 microns in size or smaller. PM2.5
is often referred to as fine
particulate matter and includes inhalable particles small enough
to penetrate the thoracic region of the respiratory system.
Research shows that smaller particles pose the greatest health
risks.

6. OSHA
•Part of the US Department of Labor responsible for ensuring
workplace safety.
•Citations can be issued in all industries by OSHA inspectors using
both the NFPA as well as selected sections of current OSHA Labor
Standards (CFR 29, Section 1910) pertaining to housekeeping.
•OSHA does have enforceable regulations for fire protection,
ventilation, general environmental controls, and hazardous
materials. Uncontrolled dust in your facility may be a violation of
any of these.
•OSHA can impose serious fines in situations where workers are
injured or killed on the job due to a combustible dust explosion
because employers did not correct a dangerous situation.
•Even though OSHA does not have combustible dust regulations,
state and local safety administrations or building codes may have
regulations that are much stricter than OSHA’s.

7. OSHA
OSHA has issued a variety of guidelines and
recommendations for combustible dust safety.

8. NFPA standards are the basis on which many state and local
governments set their safety regulations.
•NFPA 652 - Standard on the Fundamentals of Combustible
Dust Outlines:
- Definitions
- General requirements
- Hazard identification
- Performance-based design option
- Process hazards analysis
- Hazard management: mitigation and prevention
NFPA Standards

9. NFPA Standards (cont.)
•NFPA 652 - Standard on the Fundamentals of Combustible Dust
Provides the general requirements for management of combustible dust fire and
explosion hazards and directs the user to these NFPA industry- or commodity-specific
standards:
•NFPA 61 – Standard for the Prevention of Fires and Dust Explosions in Agricultural and
Food Processing Facilities
•NFPA 484 – Standard for Combustible Metals
•NFPA 654 – Standard for the Prevention of Fire and Dust Explosions from the
Manufacturing, Processing, and Handling of Combustible Particulate Solids
•NFPA 655 – Standard for Prevention of Sulfur Fires and Explosions
•NFPA 664 – Standard for the Prevention of Fires and Explosions inWood Processing
andWoodworking Facilities

10. NFPA Standards (cont.)
•NFPA 68 - Standard on Explosion Protection by DeflagrationVenting
Applies to the design, location, installation, maintenance, and use of devices and
systems that vent the combustion gases and pressures resulting from a deflagration
within an enclosure so that structural and mechanical damage is minimized.
•NFPA 69 - Standard on Explosion Prevention Systems
Provides requirements for installing systems for the prevention and control of
explosions in enclosures that contain flammable concentrations of flammable gases,
vapors, mists, dusts, or hybrid mixtures. It is intended for use by design engineers,
operating personnel, and authorities having jurisdiction (AHJs) over the fire code of a
particular area.

11. Need Help Staying Compliant?
•Sly can work with you to configure OSHA-
compliant combustible dust explosion
protection systems per NFPA 654, 68 and
69, etc.
•Our founder,WilliamW. Sly, was granted
the very first patent for a cloth-type dust
collector (U.S. Patent No. 710,624), in 1902.
•With nearly 150 years of pollution control
expertise, Sly is a trusted advisor to leading
manufacturers in designing industrial dust
collector and wet scrubber systems.
•We manufacture our own dust collectors
and scrubbers and can customize our
solutions for a wide range of applications.
