What is the egress width in a public cafeteria in a hospital? It leads to the outside.
Question is way too vague to answer. Which component of egress are you referring too, corridor width, door width? What is the occupant load of this egress component? Do other spaces in the building egress through the cafeteria?
Section 1005 of the International Building and Fire Codes regulate means of egress sizing.
A cafeteria is an "assembly" occupancy. To determine egress width, refer to Chapter 7, Section 7.3 Capacity of Means of Egress. A variety of site specific information must be typically known to calculate egress capacity: occupant load, number of egress paths, number of exits, points of convergence, etc.
Are you trying to determine the minimum width of the aisle within the cafeteria that leads to an exit OR the width of the exterior exit door itself?
Thank you for replying. I am actually looking for the width of one of the walkways that lead from the cafeteria out to the dining part of the cafeteria. There are two other ways out of the area so not even sure it matters but I think it might be too narrow of an area.
Thank you for your help.
Were you able to take a measurement of the width of the area in question? Transition areas between serving and dining can be bottle necks, esp. around cash registers and condiment stations. In addition to maintaining the required "means of egress" for the LSC certain aspects of the ADA for those with disabilities likely come into play when evaluating the width of such aisles or passageways.
As Milton suggested assembly areas can be a bit complicated to evaluate. A good starting point is to determine the occupant load of the serving area and number and type of exits from it along with the dining area occupant load and the number of and type of exits from it. Then the actual table layout, number of aisles, and width of aisles leading to exits would need to be evaluated. If the dining area is also used for other hospital functions without tables (i.e. standing room only), with rows of seating, etc. separate evaluations would need to be made for each such configuration.
I did take a measurement of the area of concern. It was 39 inches and it was where a condiment station and coffee station intercept .It was concerned because of the bottlenecking that might occur and also the ADA requirements. . This particular area is also adjacent to the registers , which you have to pass thru to get to the dining area which walkways are 6 feet wide. They lead to outside exits which are also 6 feet wide.
I wasn't able to open your attachment. From my experience, if you have at least 44 inches clear width you will probability meet most code minimum clear width requirements. Meeting the minimum clear width is only one part of the analysis. 48 inches will give you a capacity of 240 persons at .2 inches per person (Table 184.108.40.206). Now you need to consider the occupant load as it can not exceed the capacity of this narrow area, You should consult table 220.127.116.11 of the LSC. Using 7 sf per person factor because of the people standing and waiting to be served. If the net square footage of the available standing room of the cafeteria is greater than 1680 square, you will require a clear width greater than 48 inches and the clear door widths in the exit access would need to be evaluated. If there are other exit accesses, you can account for the total egress width. Say you need 144 inches of egress width because of the occupant load (net area x occupancy factor of 7 sf per person) in the cafeteria and you have three exit accesses with a 48 inch clear width. You can divide the capacity by 3 so the 48 inches would be okay. But you still need to evaluate the clear door widths in all the means of egress from the cafeteria. A 36-inch door only give you 170 person exit capacity (34 / .2 =170).
Hope this helps as the concept sometimes becomes confusing with multiple means of egress.
If I read your question correctly, you may be requesting the LSC sections to consult for the general requirements for access and egress routes within a assembly area. Did you want to know the minimum width requires for aisles and pathways for exit access? Please refer to Section 18.104.22.168 (new) or 22.214.171.124 (existing) of the LSC assembly occupancies which ever is applicable. There are several (too many to mention in this message) requirements for access and egress routes within assembly areas.
After you have a chance to review those codes and have a particular question about a specific code, please let us know. I would like to collaborate with Lawrence if possible. Seems like he has had some healthcare facility experience as I have (25 years as an engineer consulting for a state healthcare licensing and CMS survey agency). I am retired now and would like to help using my experience. Its good use of my free time.
44 inches would be the minimum corridor width.
Thank you Ray
I thought it was 48 but wanted to make sure before I told the kitchen manager.
Personally, I am bit reluctant to just throw out a minimum number without knowing more specific information about your arrangement for these reasons:
IBC 1020.3 Obstruction. The minimum width or required capacity of corridors shall be unobstructed.
I agree with Lawrence as more information is needed to prevent speculation. I can only envision your cafeteria as the hospital cafeterias I have reviewed the past. I also concur with his assessment.
Assembly occupancies are the most dense population in use areas of all the occupancies of the LSC and require the most diligent review to ensure all the egress components comply. The last plan review I did of a simple addition to a hospital involved determination of the egress capacity of the entire facility. It took 2 hours to calculate the occupancy loads and determine the egress capacity of the most restrictive egress components. It was a very systematic process to do the review to evaluation each of the egress routes.
My suggestion would be that you get a hold of the original approved plans for the construction of the cafeteria and dining room and compare them against the actual layout of equipment to see if any major differences in the egress routes. It should also have an approved table and chair layout. Hopefully, the original plans had a code review sheet that has occupant loads and egress capacity determinations that could help you. At least some assurance of compliance may be gained from the design team's original review. I would ensure the actual egress components comply with those original plans. This may take removing or relocating some fixed or movable construction, tables, chairs, or equipment. If you want to modify the construction from those original plans to accommodate the current equipment and dining room table layout, I would certainly have the architect's design team review those modifications. I my jurisdiction, those types of modifications must be reviewed and approved by that state's healthcare licensing agency.
Tons of sage advice for you from Milton! Those approved occupancy numbers and table layouts are invaluable over time.
Getting tables back to where they belong after floor maintenance, special events, even after a routine meal can be a ongoing challenge. A bigger issue we see a lot is whenever dining furniture is replaced a new table layout and occupancy calculations are not provided. In my experience, there is almost always a tendency to see more seats afterward than what existed before. Furniture salespeople will help you maximize the space and gladly sell you as many tables and chairs as they can; but more often than not, disregard occupant loads and egress width because they have little to no training in the building / fire codes and their commission incentivizes them to sell as much product as possible.
Some AHJ's require a sign on the wall stating the maximum occupancy. I would recommend taking a look to see if such a sign is in place (or alternatively review construction drawings for similar information) and verify the current number of seats do not exceed that maximum. Even if an occupancy sign is not required I would recommend posting one anyway to help prevent an over capacity situation. I see many organizations posting table layout (often multiple layouts for various types of events) to both help set-up personnel as well as those who tear-down or do maintenance to better ensure life safety is never compromised during various types of events.
Thank you everyone for your input. The solution was pretty simple, I just had them move the new vending machine to a different area and we are now compliant.
It was not in the dining area so did not have to calculate tables and chairs at all.I am so glad that I finally got a subscription to this because everyone is so helpful.
Thanks for the kind words!
