Chemical and Radioactive Waste Safety

Combustible dust hazards are common in industry and have gained additional exposure due to the OSHA Combustible Dust National Emphasis Program (NEP) which was re-issued as a result of the fatal accident at Imperial Sugar. Fauske & Associates, LLC (FAI) offers a wide range of services related to Dust Hazards Analysis (DHA) characterizing, preventing and mitigating combustible dust explosion and fire hazards. These services include combustible dust testing, onsite assessments, OSHA and NFPA compliance assistance, audit preparation, training, ignition source evaluation and vent sizing calculations.

Our process safety professionals have served clients in a variety of industries including metal processing, wood/paper products, agriculture, food products, textiles, plastics, pharmaceuticals and many others.


Chemical and Radioactive Waste SafetyActive nuclear fuel cycle facilities and commercial nuclear power plants scheduled to be decommissioned and dismantled generate waste streams that consist of many chemical and physical forms.  During processing, packaging or storage, some waste materials have the potential to undergo chemical reactions that liberate heat and gaseous products Such facilities must establish operational limits and safety precautions by determining which chemical reactions could occur, how rates of reaction vary with temperature and what the nature of the reaction products will be. 

Testing & Services

Fauske & Associates, LLC (FAI) performs testing and provides calorimetry equipment to collect chemical reactive system data needed for process design and safety.  FAI services (with equipment that can be used in hot cells) encompass:FAI ARSST

  • Advanced Reactive Systems Screening Tool (ARSST) for chemical reaction heat-up and pressurization rates (10 ml scale) 
  • Vent Sizing Package 2  (VSP2) for reactive system characterization, including venting and flow characteristics with measurement of heat up and pressurization rates during a process upset (100ml scale)

Both the ARSST and VSP2 are designed to simulate runaway chemical reactions so their data can be directly scaled to process conditions.

FAI VSP2FAI also supplies measurement services including: 


FAI was the prime contractor for the Design Institute for Emergency Relief Systems (DIERS) for the American Institute of Chemical Engineers.  In that capacity, the company’s primary role was the development of the state-of-the-art calorimetry technology and design application methodology.  More than 300 reactive system calorimetry units have been sold by FAI to companies worldwide.

In addition to offering reactive system calorimeters, FAI operates a complete world-class process safety lab with the instruments and software necessary to perform any process safety study and also has large scale and speciality testing capabilities. 


FAI recognized for contributions to Hanford SNF technical basis
