Are 'Explosion-Proof' (EX) cranes worth the 40% premium for refinery use?
Yes, EX-rated cranes are essential for Class I Division 1/2 areas in refineries where ignition sources could cause catastrophic explosions.
Explosion-proof cranes are mandatory, not optional, in refinery environments classified as hazardous locations under NFPA 70. The 40% premium is justified when considering potential consequences: a single ignition event could result in millions in damage, fatalities, and regulatory shutdowns. Standard cranes create sparks through motor brushes, electrical contacts, and static discharge that can ignite hydrocarbon vapors.
Remember: "EX-pensive but EX-plosion prevention = EX-cellent investment for refineries"
