WHAT CAN HAPPEN IF A LARGE OPENING IS COVERED BY A NON-FIRE RATED ROLLING STEEL DOOR?

A large opening covered by a rolling steel door that is not fire rated will not automatically close under fire conditions, allowing an opportunity for fire and burning objects to pass through from one side of the opening to the other and thus setting up the possibility for compromising life and property. Common applications include factories, warehouses, mills, distribution centers and parking garages.

INSPECTION

• Inspect fire doors for damage to guides, curtain and endlocks, bottom bar, hood and operating mechanism.
• Ensure that the door’s operating mechanisms, fuse links and release chain/cable are not painted, coated with dust or grease, and/or covered with debris.
• Open and close the door to inspect for any indications of damaged parts.
• Remove flammable substances on each side of the firewall opening near the fire door.

DROP TEST

• Have our trained door systems technician perform an inspection and drop test of all fire door automatic closing features.
• Fire door deficiencies identified during the pre-drop test inspection should be corrected before the drop test. The drop test contract should acknowledge the fact that components may fail during the drop test that are not the fault of the service provider and are not included in the cost of the drop test.
• Document the drop test
• When subjected to drop testing, the door must close completely and rest on the sill.
• The door must be drop tested twice – once to verify proper operation and full closure, and a second time to verify that the automatic closing device was properly reset.
