Is Your Facility Protected by Correctly Sized Explosion Vents?

Combustible dust explosions remain one of the most severe hazards in industrial facilities. When explosion vents are undersized — or sized using outdated methods — the consequences can be catastrophic: structural damage, injuries, fatalities, and significant regulatory liability.

NFPA 68 provides the standard framework for explosion vent sizing, but applying it correctly requires understanding a complex set of inputs, calculations, and special-case adjustments. Most safety professionals learn these skills on the job, leaving gaps that put facilities at risk.

This course closes that gap. In approximately 60 minutes, you will move from uncertainty to confidence — with the practical skills to calculate vent areas, assess your facility, and demonstrate compliance with NFPA 68.

Practical Solutions You Can Apply Right Away

01
In-Depth Understanding

Discover the essential inputs for designing effective explosion venting systems and learn how changes in parameters directly impact vent sizing outcomes.

02
Accurate Risk Assessment

Enhance your ability to accurately assess risk levels at facilities handling combustible dust, and communicate findings with confidence to stakeholders.

03
Regulatory Compliance

Learn how to comply with local, regional, and national standards including NFPA 68 requirements, reducing your facility's regulatory exposure.

04
Peace of Mind

Gain the confidence to manage dust hazards effectively, ensuring a safer working environment for your team and protecting your operations.

Inside the Training Program

Six structured lessons walk you through the complete NFPA 68 vent sizing process, from gathering initial data to managing complex special cases.

Intro
Introduction
Course overview, learning objectives, and the fundamentals of explosion venting.
L1
