- Emergency action
- A) Following the alarm given by the worker, the safety crew began by sprinkling the rack with the fire hose, notified external first responders and manually activated the emergency shutdown: H2 production was halted and nitrogen purging of sensitive installation parts was initiated.
B) When fire-fighters arrived 15 min later, the rack had emptied and the fire had stopped burning. Nonetheless, sprinkling was continued due to the very high temperature of the bottles, whose barrel remained incandescent until an infrared pyrometer became available on-site to evaluate the bottle wall temperature. The entire facility was evacuated. An hour later, with the rack temperature dropping to 25°C, the alarm was lifted..
