Noncompliance with Corridor Door Fire and Smoke Resistance Requirements
Penalty
Summary
A deficiency was identified regarding corridor doors and doors protecting corridor openings, which did not meet regulatory requirements for resisting the passage of smoke and fire. The report notes that doors in areas other than required enclosures of vertical openings, exits, or hazardous areas must be constructed of 1 3/4 inch solid-bonded core wood or other approved materials capable of resisting fire for at least 20 minutes, unless the smoke compartment is fully sprinklered, in which case only smoke resistance is required. Additionally, corridor doors and doors to rooms containing flammable or combustible materials must have positive latching hardware, and roller latches are prohibited. The clearance between the bottom of the door and the floor covering must not exceed 1 inch, and there must be no impediment to the closing of the doors. The report also specifies requirements for powered doors, hold open devices, protective plates, Dutch doors, and door frames. The deficiency was cited due to noncompliance with one or more of these requirements, as evidenced by the survey findings.
