Close the gap with too many gap seals on the door (2023)

Door gap solutions help hospitals and other facilities reduce the gap between fire doors and their frames and prevent fire inspection code violations. The recent code compliance updates from the Centers for Medicare and Medicaid Services (CMS) to NFPA 80 mean thatCompliance with fire doorsViolations can result in CMS being denied funding, which can have serious financial implications for many hospitals. Additionally, fire door replacements in healthcare facilities often cost thousands of dollars if the doors are not within the correct tolerances, making over-door opening kits a much more cost-effective solution.

If you are a facility manager looking to remedy excessive fire door spacing or are unsure of the clearances specified in NFPA 80, we will guide you through fire door compliance with precise assignments for bottom, top, and perimeter spaces . .

What are the excess space solutions?

One solution to excessive door clearance is a door extender, which reduces the gap between the door and the doorframe or between the bottom of the door and the floor.

There are three types of door opening extenders, including bottom, top and wraparound opening extenders. The third solution is attached to the frame, extending the height of the frame at the edge of the door.

The door opening is the space between a fire door and the frame or floor. This can be dangerous when fire and smoke pass through the door, which is why fire inspectors have started to inspect rooms more closely in recent years.

Also known as fire door opening stops, door opening seals, fire rated door extensions or door bottoms, these extensions are usually made of stainless steel, although Pemko also sells a door opening shoe. aluminum for easy on-site modification.

What are fire door sets used for?

Many buildings, including hospitals and other healthcare facilities, incorporate fire doors where such an assessment is required by building codes. These doors must pass an annual fire test, which ensures that door openings that could cause fire and smoke to spread are within specified limits.

Many hospital facility managers, fire safety consultants, and engineers have found that gaps in their doors are much larger than specified by the National Fire Protection Association (NFPA). You can find this code atNFPA 80, Standard for Fire Doors and Other Opening Protective Devices.

When facilities receive fire inspections, an inspector may determine that the gap between the frame and the door is too large. This will trigger an alert to fix the problem within a certain amount of time. Sometimes the door is crooked, has given way over time, or new flooring has been installed to create this space. Unfortunately, there isn't always an easy way to close the gap. Because of this, overhang kits have become invaluable in solving these problems.

If your installation has hundreds of fire doors with very large openings, repairing them by replacing the doors can be very expensive, especially as replacing one door can cost thousands of dollars.

A Pemko door opener kit covers the gaps and meets fire regulations (through third-party testing) and costs a fraction of what it would cost to replace the entire door. These solutions also ensure that by promptly resolving fire door breaches, your installation is unlikely to be denied CMS funding.

What clearance is allowed for fire doors?

Even if your facility has had the same door as offenders for the past 20 years, CMS requires all healthcare facilities to follow the 2012 edition of NFPA1010, Life Safety Code. The maximum free space allocation has changed from the previous acceptable 2000 edition.

These are the current maximum allowable port clearances:

Door space below:

  • ¾" max clearance

Between the door and the frame gap (side or top):

  • Maximum spacing of ⅛"

Space for adjacent edges of side doors:

  • Maximum spacing of ⅛"

Top 3 problems of excessive door play

For hospitals and healthcare facilities, oversized fire doors create safety, financial and funding potential issues. However, excess clearance kits can also be installed in any building that requires fire doors. These include hotels, large offices, stairwells and schools.

Excessive door openings are particularly dangerous for several reasons, but here are some reasons why it's best to start installing excessive opening solutions before your next fire inspection:

1. Fire and smoke spread through door gaps

If gaps are larger than allowed, heat, fire and smoke can penetrate under and around the door. This can cause the latches to break, especially if you have a pair of swinging doors, as the heat from the fire can bend and bend them, causing further damage. In addition, occupant safety can be compromised if noxious vapors penetrate a bulkhead or fire barrier at higher than allowable rates.

2. Low fire ratings and failed fire inspections

Excessive door clearances are one of the main reasons facilities fail fire inspections. Facility managers should verify that all door clearances meet standard specifications. While most facilities have 60 days to resolve these issues, fines and penalties can also be imposed depending on code violations.

3. Loss of Financing

Depending on the severity of the fire safety breach, hospitals could face a loss of funding from CMS, including a refusal to pay any individual Medicare or Medicaid. Other sanctions may include government surveillance, relocation of residents and termination of agreements.

Prepare for fire inspections with solutions to excessive door clearances

It is important to protect your assets and avoid fire hazards. This not only protects your facility from failing a fire inspection, but is essential for saving lives if a fire does occur. With Pemko door opening solutions, you can ensure compliance and save thousands of dollars by not having to replace doors or fix floor issues.
