Smoke Doors

Smoke Door Assemblies:

NFPA 105, Standard for Smoke Door assemblies and Other Opening Protectives, defines a smoke door assembly as, ‘Any combination of a door, frame, hardware, and any other accessories that together restrict smoke movement through door openings by limiting the amount of air that can pass through the assembly.’ These assemblies are commonly referred to as simply ‘smoke doors’.

The primary purpose of a smoke door assembly is to limit the passage of smoke through a facility.

When doors are labeled as a smoke door, the designation is simply ‘(S)’, along with any special requirements.

On the smoke door label below, the last line identifies the door as smoke rated (S) and defines a requirement for gasketing:

Smoke door assemblies may also be fire rated and if so must comply with the requirements of NFPA 80.

Historically, once a facility was occupied, smoke doors were not subject to any ongoing maintenance reviews or inspections. But this changed starting with the 2007 edition of NFPA 105.

NFPA 105 -2010, Section 5.2.1, Inspections, defines inspection requirements as:

Paragraph Smoke door assemblies shall be inspected annually

Paragraph A written record shall be maintained and shall be made available to the authority having jurisdiction.

Paragraph Records shall be maintained for not less than 3 years.

Smoke Door Inspections:

Doors are one of the most used components in a facility and are subject to modifications or alterations which change their intended function. Even one year old doors may have been modified or altered and may no longer function properly.

DepartSure offers various smoke door services:

1. Annual Smoke Door Inspections: We complete annual inspections, complete the necessary reports, and maintain the reports as required by NFPA 105. We submit a signed written report to be inspected by the AHJ. The reports may be maintained electronically, if desired.

2. Education - Documenting Smoke Door Inspections: All smoke door inspections require documentation (a report). Completing a report requires properly identifying doors for the inspection and reporting process. We recommend labeling doors with field-applied labels, preferably bar codes. We educate your staff how to define and document doors, including on a BBI drawing (required in healthcare).

3. Education - Preparing for a Fire Door Inspection: The best (i.e. lowest cost) approach, initially, is to review doors prior to a formal inspection. This allows a facility maintenance team to identify easy and/or gross deficiencies and have them corrected prior to a formal inspection. But you don’t know what to fix if you don’t know what the inspector looks for! We educate your maintenance staff what to look for – or we can complete an initial, pre-formal inspection and assess deficiencies for you.

Smoke Door Commissioning

An owner expects a newly constructed or renovated facility to function as designed and intended. To achieve this, a facility commissioning agent (FCxA) is often named and included in project contractual documents. When commissioning a fire protection and life safety system, NFPA 3 (Recommended Practice for Commissioning of Fire Protection and Life Safety Systems) is utilized.

As part of a commissioning team, DepartSure serves as a door assemblies subject matter expert (SME).

NFPA 80 requires a post-installation review and report of new fire door installations. Although not required by NFPA, we recommend completing a post-installation review and report on smoke doors. These doors require annual inspections as defined in NFPA 105 -2010 and the Life Safety Code, NFPA 101 -2012, respectively.

Sometimes multiple inspections (and reports) are required to attain proper smoke door function.

Smoke Door Repairs:

The top fire door and smoke door deficiencies include:

  1. Painted or missing labels
  2. Poor clearance dimensions around the perimeter of the door in the closed position
  3. Missing or incomplete smoke gasketing applied around the perimeter of the door
  4. Auxiliary hardware items that interfere with the intended function of the door (barrel bolts and dead bolts, etc.)
  5. Area surrounding the smoke door assembly blocked by furniture, equipment, and/or boxes
  6. Broken, defective or missing hardware items (latch bolt, and/or strike plate, closer arms, cover plates, etc.)
  7. Doors retained in the open position
  8. Removal of hold open devices (wood wedges, kick down door stops, etc)
  9. Gap adjustment
  10. Silencer replacement

DepartSure repairs smoke doors per NFPA 105.

Sometimes a door simply cannot be repaired and complete replacement is necessary. In this case, DepartSure can manage the installation of new doors and/or hardware.

After the repair or replacement of a smoke door, DepartSure will re-inspect the doorway and issue a revised report noting the corrected door condition.
