Theme for the month - Nitrogen related incident

Employee stepped into a control cubicle where the instrument air was temporarily replaced with N2 during shutdown. The green light outside the door was on indicating safe atmosphere. As soon as he stepped into the cubicle his personal O2 monitor alarmed indicating 18% O2 or less.
After exiting safely he opened the door and when O2 level was OK, checked the fan. The ventilation fan was not running. The light was wrongly wired.
