On-site Assessment of Combustible Dust Hazard


DHA Helps to Make the Decisions

Combustible Dust Hazards are a concern for every industry and plant - in particular, pharmaceutical, food/agriculture, plastics/polymers, metal, wood, cosmetic, and manufacturing. Simple Go/No-Go tests are inexpensive and can help save a lot of time and heartache. These simple tests help to make proper equipment purchasing decisions, meet safety standards and stay ahead of the game when it comes to dust hazards.

Comprehensive In-plant Analysis of Dust Hazards

A Combustible Dust Hazard Analysis or Assessment (DHA) is a comprehensive look at your dust within the complete framework of your workplace, its operations and equipment. AST Canada offers a wide range of services related to Dust Hazards Analysis  including characterizing, preventing and mitigating combustible dust explosions and fire hazards.

How Dust Hazard Analysis Works

Air Separation Technologies, Inc.(AST Canada) combustible dust experts visit your facility to evaluate your receiving, storage, use, processing and disposal of all “powder” materials.  They will evaluate existing dust management programs, handling practices, equipment, fire/explosion suppression systems, warning devices and onsite extinguishing capabilities.  Possibilities for fugitive dust control will also be identified where appropriate.  AST Canada can provide the following services: 

   •  Incident investigation for dust explosions and fires
   •  Evaluate compliance with relevant national, local and industry standards
   •  Electrostatic hazards assessment – e.g. grounding and bonding issues
   •  Recommendations for explosion hazard risk reduction
   •  Identify dust sampling points and collect samples for dust explosibility testing

NFPA and M.O.L. Combustible Dust Compliance

   •  Preparation for an M.O.L. Combustible Dust inspection, including appropriate responses to inspector’s questions
   •  Perform a Process Hazard Analysis (PHA) for M.O.L. compliance
   •  Documentation review for NFPA and M.O.L. Combustible Dust requirements
   •  Testing services to meet all NFPA and M.O.L. Combustible Dust requirements
   •  Conduct employee training to comply with M.O.L. Combustible Dust requirements

Additional Services

   •  Vent size calculations for new or existing equipment 
   •  Ignition source evaluation (NFPA 654 and 77)
   •  Development of process safety programs to manage combustible dust hazards or integration of combustible dust hazard management into existing process safety programs.
