Required Width of an Excess Access Corridor

Q: What is the required width for an exit access corridor in an office building?

A: That depends on the occupancy classification of the building. If the building is classified as business occupancy, then sections 38/ of the 2000 Life Safety Code (LSC) would apply. The clear width of an exit access corridor in a business occupancy (office building) serving an occupant load of 50 or more, is 44 inches. But for occupant loads less than 50 persons, section of the LSC would apply and the clear width is lowered to 36 inches.

When the Life Safety Code talks about the occupant load of a room or area, it is always calculated per section 7.3. Table has occupant load factors that are used along with the gross area to determine the number of persons allowed. For a building classified as business occupancy the occupant load factor is 100 square feet per person. This means in order to have an occupant load of 50 persons you need 5,000 square feet of area.

If the office building is classified as an ambulatory health care occupancy, then according to section 20/, the required width of the corridor is limited to just 44 inches. There are no deviations for less than 50 occupants.

What… More on Corridor Doors?

Q:  These corridor doors (i.e. patient rooms); if they are in a 1-hour fire barrier then is it okay for them to only be rated20-minute and not ¾ hour?

A: The answer is no. If a corridor door is part of a fire-rated barrier that serves some other function, such as a vertical opening, exit, or hazardous area, then it must meet the most restrictive requirements of either. In the scenario that you mentioned in your question, the corridor door must be at least a ¾ hour fire rated door, mounted in a fire-rated frame, with self-closing and positive latching hardware. Vertical openings are elevator shafts, mechanical shafts, stairwells, and the like. Exits are horizontal exits and exit passageways. Hazardous areas are storage rooms >50 sq. ft. containing combustibles, soiled utility rooms, fuel-fire heater rooms, laundries >100 sq. ft., paint shops, repair shops, trash collection rooms, laboratories, medical gas rooms (storage rooms with >3,000 cubic feet of compressed gas), and gift shops. I don’t see where a patient room door would be part of any of these fire-rated barriers. However, a patient room door could be part of a smoke compartment barrier. Even though the smoke compartment barrier is required to be 1-hour rated, it is not a fire rated barrier, because the doors in a smoke compartment barrier are only required to be 1¾ inch thick, solid-bonded, wood core doors, or of such construction to resist fire for at least 20 minutes, and must be self-closing. They are just like corridor doors, but must have closers on them.

Still More on Corridor Doors

Q: Do you think adding tons of signage, and coat hooks would be acceptable on a patient room door?

A: Well…. That depends. Coat hooks on a non-fire rated door? Yes, that would be allowed. Tons of signage? That depends… if the signs were considered ‘decorations’ then section of the 2000 LSC applies and combustible signs that are considered decorations would not be permitted. Signs that were informational (i.e. contact precautions; oxygen administered; diet restrictions, etc.) would be permitted, even if they were combustible.

More on Corridor Doors

Q: If the corridor doors are only required to resist fire for 20 minutes and someone plasters signage all over them or loads them up with coat racks adding to the fuel load, then who decides if they would still resist fire conditions for 20 minutes?

A: The doors are not required to resist fire for 20 minutes. They are required to be 1¾ inch thick, solid-bonded, wood core, or of such construction that resist fire for not less than 20 minutes. That is not the same as saying they are required to resist fire for 20 minutes.  Therefore, nobody has to decide if they still resist fire for 20 minutes, because the construction of the door was determined acceptable before any items were added to the door. This may sound like a technical loop-hole, but the point I’m trying to make is there should not be a reason for anyone to determine if a corridor door resists fire for 20 minutes. NFPA has indicated that a 1¾ inch solid-bonded, wood-core door is of such construction to resist fire for up to 20 minutes (see section of the 2000 LSC).

Corridor Doors

Q: I have read that corridor doors to patient rooms are not required to have closers. If they do have closers, I was told they can have the type that have hold open closer arms, then someone must physically close them.  Hospitals are defend in place facilities so why rely on people to accomplish this?

A: Corridor doors to patient rooms are not required to have closers, according to of the 2000 LSC. The concept of having corridor doors to patient rooms without closers allows staff to visibly see into the room to detect any fire or smoke condition. If the door had a closer, then the Annex section recommends the room be protected with a smoke detector. The basic premise of a healthcare occupancy is there is adequate staff on hand to make these observations.

Corridor Width

Q: Can you give me the NFPA Life Safety Code (2000 edition) reference showing 8 foot required width in egress corridors in an existing healthcare occupancy?

A: There is no direct LSC reference that requires 8 feet wide corridors in existing hospitals. But; it’s an interpretation. Section of the 2000 Life Safety Code says corridors have to be at least 4 feet wide in existing healthcare occupancies. Section 4.6.7 says when you make alterations, you must meet new construction requirements. Section requires 8 feet wide corridors in new construction healthcare occupancies. So, let’s say you have 7 foot wide corridors in an existing hospital. That’s legal. But the minute you make an alteration (including storing something non-combustible in the corridor) now it must meet the requirements for new construction, which is 8 feet. So, the correct way of stating corridor width in existing healthcare occupancies is the corridor must be free and clear up to 8 feet wide. If the corridor is 7 feet wide: That’s okay as long as the width is free and clear.

Handrails in Corridors

Q: I am working on an aesthetic corridor remodel for a hospital. Can you please tell me if there are specific requirements as to handrail locations (i.e- one side of the wall vs. both sides, at what locations, for what amount of distance, etc.)?

A: In regards to healthcare occupancies, and specifically hospitals, there is no Life Safety Code requirement for handrails in an exit access corridor. There are requirements for stairs, exit enclosures, ramps and exit passageways to have handrails, but the LSC does not have any requirements for corridors. However, there are other codes and standards to consider. The Facility Guidelines Institute requires hospitals to comply with ADA requirements in regards to handrails in corridor, unless the functional program narrative specifically decides against them. What this means, if the hospital has a written program that describes the use and activities that the corridor serves is not consistent with handrails, then it is permissible not to install them. An example of this may be a Psychiatric unit where a handrail could possibly be removed and used as a weapon. In essence, the hospital gets to decide if there will be handrails, but the reason needs to be plausible and written down in a program narrative. Also, compliance with ADA requirements is required whenever new construction or renovation of an existing area is conducted. I do not believe just installing new wallpaper qualifies as renovation, so compliance with ADA would not be required. I strongly recommend that you contact the local and state authorities to determine if they have regulations that would require handrails.

A Follow-Up to “Comments on Corridor Clutter”

The following comment is a result of an article that I ran last August on corridor clutter (search: Comments on Corridor Clutter), which quoted Randy Snelling, the Chief Physical Environment Officer for DNV.GL Healthcare, Inc. This comment is from a representative from a state agency that performs surveys on behalf of CMS.

First, I totally agree with both Randy and you. Both in principle and standard we should be  more up to date and facilities should know what the standard is and how to  follow it. Oddly, I spend more time assisting facilities on this issue even when I cite it. I tend to smile when they announce I have arrived and wonder “Were you in compliance yesterday?”

As a surveyor doing checks on all occupancies, I have found none ever seem to not have some issue with space and where to place those items needed for patient/resident care. Having worked in a healthcare facility, I can also fully relate that focus being first and foremost.

That being said, the standard is there for a reason and has been for some time.  Even though my initial peek into 2012 finds some increasing awareness of how clutter is viewed, I still believe that we have a wide arrangement of options if, as both you and Randy point out, senior management buys into it and
supports either their Safety Manager or Maintenance staff.

Inevitably, these are the ones who take it very personally when I cite a facility for a blocked or obstructed corridor. Administrators, Chief Nursing Officers on down need to understand the reasoning behind the code and what steps it takes to stay in compliance. I feel a majority of the time the facility management thinks “Oh we clear everything when the drills happen”. Now imagine those corridors filled top to bottom with smoke. The scenario will change considerably. I hope all who read your article and Randy’s comments take it to heart.

I think this representative for a state agency makes a very good point: The healthcare industry needs better education on the need to keep the corridors clear from clutter. I suspect we have become insensitive to this issue because the frequency of fires in hospitals has dropped dramatically since the mid-1980’s, when smoking was restricted in hospitals.

But fires still occur in healthcare settings as documented in either this blog or in the HCPro’s Healthcare Life Safety Compliance newsletter. And it is the belief of Randy and I (and this representative from a state agency) that corridor clutter still needs to be taken seriously.

In my opinion, it did not help that the NFPA Life Safety Code technical committee decided to allow certain unattended items in corridors of 8 feet as described in the 2012 edition. It also didn’t help that CMS decided to endorse this section of the 2012 edition last year as a categorical waiver. The decision on the technical committee to do this was not unanimous, as a representative from a state agency who surveys hospitals (not the same individual quoted above) enthusiastically opposed the decision. Since he had first-hand observation on how hospitals abuse codes and standards, he did not want to allow them to store items in the corridor.

I suspect corridor clutter will remain a problem until senior leadership decides to take an active role in resolving it.

Comments on Corridor Clutter

Randy Snelling, the Chief Physical Environment Officer, for DNV-GL Healthcare Inc. spoke at the recent ASHE annual conference in Chicago, and I thought his views on corridor clutter were worth repeating here…

“I read in the ASHE magazine recently an article written by a surveyor who listed the top 5 findings he saw during a survey”, says Snelling. “The first thing he identified was corridor clutter. I threw the magazine across the room. I thought, ‘Man, where are we? This is 2014 and we’re still talking about corridor clutter? Really? Come on!’ Why is corridor clutter still happening in hospitals? Because the senior leadership is not stepping in. The facility manager does not have the clout with those clinicians up on the floors where the corridor clutter occurs. But who does? Senior leadership. And if you’ve got corridor clutter problems, it’s not a life safety problem, it’s a ‘C’ suite problem. And our hospitals know it. I don’t think we’ve had a corridor clutter finding in over a year. Now, what happens? Well, we come in and the hospital makes an announcement overhead welcoming the DNV survey team, and everything gets moved out of the corridor. But that happens with everybody else too, with HFAP and TJC and CMS. So why are we seeing this? I think it is because since we are in the hospital every year our hospitals do not have as much to move out of the corridors as other accredited hospitals. This ends up being a problem with Leadership rather than a problem with the facility manager.”

I consider Randy to be a friend and we talk frequently about accreditation issues. I think his view on corridor clutter on the nursing units is spot on, in that senior leadership needs to back the facility manager (or safety officer) on Life Safety Code issues that are out of their capability. Having been a Safety Officer at a hospital for years I can relate to this problem. I rarely felt the support from the ‘C’ suite and felt I had to struggle with certain basic life safety requirements (such as corridor clutter) on my own.

I did eventually take a different approach by spending time on the nursing units observing the nurses day-to-day operations. This made me realize their needs better and they eventually saw me as one who wanted to help, rather than the enemy who was always telling them to move their equipment out of the corridors. I was able to apportion capital funds to build alcoves in certain locations, and they in turn kept the corridor free from clutter.

But most hospitals probably still struggle with corridor clutter issues and without the senior leadership stepping in and backing the facility manager by insisting items be stored in alcoves and storage rooms, this problem will not go away. I predict it will get worse when the 2012 Life Safety Code is finally adopted, since the new LSC allows certain unattended items to be placed in corridors that are at least 8 feet wide. That will create a struggle for everyone as most staff will not understand what pieces are permitted and what pieces are not permitted.

Corridor Doors vs. Cross-Corridor Doors

Cross Corridor door web 2I have seen many facility managers (and surveyors for that matter) incorrectly refer to a door as a ‘corridor door’. It appears that they believe as long as the door is accessible from the corridor, then it must be a corridor door. That is not always the case, but it is understandable as corridor doors may be confusing.

A corridor door is a door that separates a room from a corridor, and they are usually mounted parallel to the corridor. Corridor doors are often found on entrances to patient rooms, utility rooms, offices, dining rooms, and the like. Corridor doors are often (but not always) a single-leaf door.

A cross-corridor door is a door that separates a corridor from another corridor, and they usually are mounted perpendicular to the corridor. They are typically used as privacy doors, smoke compartment barrier doors, and fire-rated doors in a horizontal exit or an occupancy separation. Cross corridor doors are usually (but not always) double-leaf doors, and if considered new construction, must be double egress, meaning one leaf swings in one direction and the other leaf swings in the opposite direction.

In reviewing accreditation organization survey reports, I have read where surveyors often refer to ‘corridor doors’ when they really mean something else. According to the Life Safety Code, a corridor door is not required to have a self-closing device (closer), unless it also doubles as a door to a hazardous room, a smoke compartment barrier door, or a fire-rated door. Also, a corridor door must latch, while a smoke compartment barrier door does not have to latch. If a door serves more than one purpose, then the most restrictive requirements must apply.

When referring to the many different types of doors that are accessible from the corridors, always refer to them by their most restrictive requirements:

  • Fire-rated doors to hazardous rooms, exit enclosures, horizontal exits, and occupancy separations
  • Smoke compartment barrier doors
  • Corridor doors to hazardous rooms, or non-hazardous rooms
  • Privacy doors

A privacy door that is a cross-corridor door is not required to latch, or be self-closing; but a privacy door that is a corridor door would be required to latch, since the requirements for a corridor door are more restrictive.
