Working Safely in Explosive Atmospheres

About Course

Video lecture: Working Safely in Explosive Atmospheres (9 minutes). Watch it before you start the lessons.

What a zone actually means, the equipment allowed in one, and the ignition source most often missed — static. Then dust, gas detection, inerting, and the permits, maintenance and emergency planning that hold it all together.

Explain why zone classification is about frequency and duration, not severity
Match equipment category to the zone it is installed in, for gas and for dust
Trace the static path from clothing through footwear to a conductive floor
Distinguish bonding from grounding and say why a bonded system can still be a hazard
Interpret a %LEL reading and explain why one clearance test is never enough
State why maintenance and reinstatement are the highest-risk window in a zone
