Breakdown
N₂ INERT
Nitrogen Inerting Protocol
Vessels purged with gaseous nitrogen until oxygen content dropped below 2% and combustible gas readings reached 0% LEL. Process repeated until three consecutive clean readings were logged.
THERMAL SHOCK
Cryogenic Shock Prevention
Controlled warm-up procedure implemented prior to nitrogen introduction to prevent thermal shock cracking of vessel walls. Temperature differential managed within 20°C/hour ramp rate.
ATEX RATED
Explosion-Proof Equipment
All purging equipment certified to ATEX Category 1G for Zone 0 environments. No non-ATEX electrical equipment permitted within the 5-meter exclusion boundary during active purging.
HAZWOPER
Emergency Response Standby
HAZWOPER-certified crew maintained on-site standby throughout all purging operations. Emergency response plan filed with local LEPC prior to mobilization.
