Event Details and Safety Significance On April 21st, a roll up fire door located between a boiler room and the rad waste system malfunctioned in the open position. The door was approximately 3/4 closed. Compensatory measures were discussed with the New Hanover County Deputy Fire Marshall and then implemented.

Immediate Corrective Actions Taken A fire retardant tarp was used to cover the opening between the bottom of the roll up door and the floor.

Probable Cause of Event A mechanical misalignment of the door tracks caused the door to jam.
