Course Design and Objectives

NFPA 652 is the “On Ramp” to combustible dust requirements contained in the various NFPA Codes. It contains mandatory requirements for the management of the fire, flash fire, and explosion hazards posed by combustible dusts. Although this standard provides some flexibility in approaches for ensuring the safety of the occupants, facility, processes, and equipment, some of the requirements must be complied with retroactively.

With over 25 years of experience in conducting thousands of Dust Hazard Analyses for our clients around the world, we have designed this two-day workshop to help you 1) better understand the applicability of this standard, 2) make compliance with its requirements manageable and practical, and 3) gain practical experience conducting Dust Hazard Analyses (Day 2).

You Will Learn

  • How to determine if a dust fire, flash fire or explosion hazard exists within your facility;
  • Effective strategies for compliance with NFPA 652 requirements;
  • How to identify dust sample(s) that need to be tested and the necessary laboratory tests;
  • How to determine the validity of any existing laboratory data you might have;
  • How to identify any gaps that exist in the required laboratory data;
  • What the requirements are for a complete Dust Hazard Analysis (DHA);
  • How to identify the gaps in your dust hazard management systems
  • How to identify gaps in your facility's dust fire and explosion prevention and protection requirements;
  • How to conduct a Dust Hazard Analysis, using practical exercises (Day 2)
  • How to identify practical measures for not only ensuring compliance but going beyond compliance. (Day 2)

Who Should Participate

Personnel involved with plant operations, including management, engineering, maintenance, Process Safety Management and auditing activities for processes where combustible dust is being generated, processed, or handled. These types of facilities include the chemical & processing industries such as bulk and finished pharmaceuticals, chemicals, petrochemicals, food, plastic & rubber, metals, textiles, wood, pulp & paper, agrochemicals and additive manufacturing.

This workshop will provide participants with the insight necessary to identify those indicators with the equipment, operations, processes, and activities that could lead to dust explosions and then help them with the steps that they can consider to not only ensure compliance but to go beyond compliance to a true safety commitment.
