Dust Hazard, Chemical Safety, Process Safety, Chemical Process Courses

Posted by The Fauske Team on 06.19.18

Midwest Chemical Safety will be offering two workshops at Fauske & Associates, LLC (FAI) July 12-13 and Fauske & Associates, LLC also just added an another NFPA 652 - Introduction to Dust Hazard Analysis and Advanced DHA courses for CEU's September 18-19 also at FAI Headquarters. July's DHA course is sold out. 

Course Descriptionsimages (1)

Effective Chemical Safety Management: A Risk-Based Perspective, Thursday, July 12, 8:30 am to 4:30 pm is an introductory course for those responsible for chemical safety in their workplaces. Chemical Hygiene Officers, stockroom managers, and principal investigators will benefit from this course. We will discuss the development of a chemical hygiene plan and standard operating procedures as well as introduce hazard and risk assessment topics using two laboratory-based tools.

Research Without Rules: Process Safety Management for Research and Small-Scale Chemical Processes, Friday, July 13, 8:30 am to 4:30 pm is a workshop designed to introduce you to performing risk assessments on various chemical processes your workplace. After introducing “hazard vs. risk” concepts and reactive chemical safety hazard assessment, we will dive into various risk assessment tools for processes from the bench to pilot-plant experimentation. We will use a number of risk assessment tools and discuss how to pick the right one for the job.

Both workshops will conclude with a session of "Ask Dr. Safety" - a Q&A period where you can bring your environmental health and safety questions and get them answered before you leave. Also, both workshops are assigned Certification Maintenance hours for ABIH which can be converted for BCSP or CHMM certification maintenance.

Location: Fauske & Associates, LLC Campus, 16W070 83rd St., Burr Ridge, IL, conveniently located to Chicago’s Midway Airport (a Southwest hub).

Cost: is $350 (ACS/AIHA/CSHEMA)/$375 (non-member). Register for both workshops and receive a great discount ($625 (member)/$650(non-member). Registration through Midwest Chemical Safety at its Workshop Page

NFPA 652 - Introduction to Dust Hazard Analysis and Advanced DHA Workshops, Tuesday, September 18-Wednesday, September 19, 8 am - 4:30 pm

Day 1 - This course will ensure all participants are aware of important issues associated with NFPA 652 and describe how this
standard interacts with other relevant NFPA codes and guidelines. A special emphasis will be placed on explaining the
requirements for a Dust Hazard Analysis (DHA) and an overview of the methodologies that can be employed to perform a
DHA. The course will also include a logical approach to characterizing a powder's hazardous dust properties, as well as a
description of various techniques used to control and/or avoid dust explosions in a safe and compliant manner.

Day 2 - Advanced workshop - The Advanced DHA Workshop will focus on how to organize, lead, and implement the DHA study. This will include how to utilize appropriate test methods to determine potential dust hazards; as well as how to apply appropriate mitigation techniques to prevent or control combustible dust hazards. During the workshop, participants will have the opportunity to apply DHA methodologies to realistic combustible dust scenarios.

Location: Fauske & Associates, LLC Campus, 16W070 83rd St., Burr Ridge, IL, conveniently located to Chicago’s Midway Airport (a Southwest hub).

Cost:  Two Day Course: $895, Day 1 only: $495, Day 2 only: $495, Each course - .07 CEUs Available.
