Dust Explosion Hazards Course

Training Period: 2 Days

Fee: USD 1,250

Dust explosions still occur on a regular basis in the process industry causing injuries, fatalities, property damage, business interruption, and environmental pollution. This is in spite of the wealth and knowledge available to prevent the accident and to reduce the consequences to a minimum.

 

In this two-day advanced course on dust and powder explosion hazards, you will learn all aspects of dust explosion hazards. The emphasis of this course is dust properties, explosion modeling, preventive measures, ignition sources, protective measures, process hazard analysis, legislation, and case studies. It enables the attendees to better understand dust hazards, to be able to recognize potentially serious events and to implement effective safeguards against the incident.

 

 

The objective of this course is to provide attendees with knowledge on the following topics:

 

  • Dust explosion hazards in the facilities, past accident and international legislation
  • Properties of flammable dust that are important to assess hazards
  • Dust explosion preventive and protection measures
  • How to assess the workplace dust explosion hazards
  • How to evaluate the consequence of dust explosion and the protection needs
  • Participation in the demonstration of small scale dust explosion

 

 

The course is aimed for people who work in chemical, pharmaceutical, food processing, automotive manufacturing, mining and other industries where dust explosion hazards exist.

 

  • Production supervisors and plant managers
  • Process and safety engineers
  • Chemical engineers
  • Mechanical and maintenance engineers
  • Safety consultants
  • Regulatory body professionals

 

 

In general, no special prerequisites are required. However, knowledge in process safety and experience in plant operation will be helpful.
