Clean Linen Stored in a Corridor

Q: If I had a hallway (breezeway which connects two healthcare occupancies) which is greater than 8 feet wide (approximately 12ft) and carts of clean linen are being stored on one side of the breezeway for more than 30 minutes, would this be allowed as long as the width is maintained at 8ft or greater?

A: Let’s re-think this situation… You have a breezeway, and you want to store clean linen in this breezeway? Do you see anything wrong with this picture…?

Talk with your Infection Control people. It does not make sense to me to store clean linen in a breezeway. Clean linen must be stored in a clean environment, such as a designated storage room for clean linen. A breezeway is not a clean environment and is not a suitable place to store clean linen.

But… if you’re asking about storing items in the corridor and if it is okay with the Life Safety Code, the answer is…. It depends.

You may store non-combustible items in the corridor as long as the required width of the corridor remains clear. You indicate the required width of the corridor is 8-feet… is that because inpatients would be using this corridor?

However, you cannot store combustible items in the corridor even if they do not obstruct the required width of the corridor. Clean linen is combustible, so therefore, to answer your question: No, you cannot store clean linen in the corridor.

Closet Doors

Q: Are closet doors located inside a corridor considered corridor doors and do they have to meet life and safety codes referring to corridor doors?

A: It depends…. What does your Life Safety drawings say?

Section 19.3.6.3 of the 2012 LSC requires doors in the corridor to be positive latching. If the closet door is in the corridor wall then it must be positive latching. However, there may be a possibility that the corridor wall could run behind the closet, provided the back of the closet wall meets the requirements of 19.3.6.2 for construction of corridor walls.

But your Life Safety drawings need to specifically identify that the corridor wall runs behind the closet. If they do not, then the surveyor has no choice but to hold your closet doors compliant to 19.3.6.3 for positive latching corridor doors.

Smoke Dampers in Corridor Walls?

Q: In regards to suite separations, section 18.2.5.7.1.2 of 2012 LSC requires walls separating suites to meet requirements for corridor walls, which have to be constructed to limit transfer of smoke. There don’t seem to be any requirements for smoke dampers in air transfer openings or duct penetrations through corridor walls – is this correct?

A: Well… you’re sort of correct. Corridor walls in fully sprinklered smoke compartments are required to be smoke partitions… not smoke barriers. The 2012 Life Safety Code does not require smoke dampers in HVAC ductwork that penetrate smoke partitions. But section 18/19.3.6.4.1 prohibits the use of air-transfer openings in corridor walls.

Strange Observations – Adjunct Corridor Width

Continuing in a series of strange things that I have seen while consulting at hospitals…

These portable X-ray units were double-parked in the adjunct corridor to the radiology control room.

The adjunct corridor is required to have 44-inches clear width, which is not present between thee two units.

 

Cabinets in a Corridor – Part 2

Q: Is there a codified requirement for doors in a cabinet mounted in a hospital egress corridor? We have worked on projects when a nurse server; i.e., pass through cabinet, was required by the local AHJ to have positive latching on the cabinet door in order to protect the sanctity of the egress corridor. But when it is just a typical cabinet (non-pass through), is there a danger to the egress corridor if the cabinet doors do not have positive latching?

A: The only code requirements that I can think of are corridor obstruction and projection. A nurse server that has an open pass-through to the patient room from the corridor is required to have a door that meets the requirements of 19.3.6.3 of the 2012 LSC for corridor doors, such as positive latching, 1¾-inch thick solid-bonded wood core, and resisting the passage of smoke, because it needs to separate the corridor from the patient room. I think a typical cabinet that does not have a pass-though would not have to have a door that is positive latching because positive latching is only required when the door is separating a corridor from a room. If there is no pass-through, then there is no need for a positive latching door.

Cabinets in a Corridor – Part 1

Q: It appears that the LSC allows up to 50 square feet of unprotected storage but also includes language that suggests it may need to be protected in accordance with 8.7 depending on the level of hazard. It is my experience that storage in a nurse station (even if combustible) is acceptable because it is located in a normally monitored and occupied area. But what about PPE or patient information storage in closed cabinets away from a nurse station? Would this decision be left to the AHJ?

A: In a scenario as you described, I believe it is all about the cabinet and doors. Is the cabinet mounted in such a way that it projects into the corridor by more than 4 inches? If so, that would be a problem. If the doors to the cabinet were to be left open, would the doors project into the corridor more than 4 inches? If so, that too would be a problem. As long as the square footage of the stored items is less than 50 square feet, I don’t see a problem. The cabinet door would not have to meet the requirements for corridor door (i.e. resist the passage of smoke, positive latching hardware, 1¾-inch thickness, solid bonded wood core) as long as the LS drawings delineated that the corridor wall ran behind the cabinet.

Strange Observations – Wall Sconce Projection

Continuing in a series of strange things that I have seen while consulting at hospitals…

Do you ever think about your corridor wall sconce light fixtures projecting more than 4-inches into the corridor…?

I do.

[Hey… AH: I made that change that you suggested.]

Strange Observations – Corridor Wall Projections

Continuing in a series of strange things that I have seen while consulting at hospitals…

Sorry for another out-of-focus picture. I was still having difficulty adjusting to my new smart phone (I should have had my grand-daughter teach me how to use it).

Maximum corridor projections are limited to 4-inches, says CMS. This stairwell evacuation chair is mounted on the wall in the corridor… It had to be relocated.

Lockers in Corridors

Q: We have a behavioral health unit and our administration would like to install lockers for visitors. However, there is only one location for these lockers and that is in the egress corridor outside of the unit. I am telling them this not permitted. Am I correct?

A: Without looking at the situation myself, I would be inclined to say it is not permitted because of the following potential issues:

  • Obstruction of the required width of the corridor (6 feet)
  • When the doors to the lockers are left open they project more than 4 inches in to the corridor
  • Hazardous area open to the corridor (combustible material in the lockers are not separated from the corridor)

Now, there could be exceptions to the above, such as:

  • If the lockers are recessed into an alcove where they would not obstruct the required width of the corridor
  • If the lockers are recessed into an alcove where an open door would not project more than 4 inches into the corridor
  • If the grouping of the lockers was less than 50 square feet, then it does not constitute a hazardous area
  • If the locker doors did not have vents and had positive latching hardware, and the doors did resist the passage of smoke, then you could qualify under 19.3.6.1 and 9.3.6.3 for corridor separation.

Overall, I don’t think it is a good idea to start placing lockers in a corridor, but there are ways to accomplish it and still be compliant with the Life Safety Code.

Strange Observations – Part 48

Continuing in a series of strange things that I have seen while consulting at hospitals…

I apologize for the photo being out of focus. I only had my new smart phone for a few days when I took this and I was having difficulty adjusting to the technology (okay… so I’m an old guy… deal with it).

The yellow sign is flexible, and is mounted on a magnet. Yet it projects more than 4 inches into the corridor.

Should I write it up …?

I did.
