Group I Occupancy Trigger Institutional Sprinkler?

3/28/2023

10 Comments

 
Does a correctional occupancy type imply secure ceilings are required?

NFPA 5000 could be interpreted as such, but as we know, it's more about the construction of the building. There is a ceilings section though so I'm unsure.

If plans called for an institutional sprinkler and secure ceilings but the owner/government changes their mind and installs standard sprinklers, is there any issue or repercussion?

Look forward to your interpretations. Thanks.

I think there could be a repercussion if the plans remove secure ceilings and institutional heads inside cells, but there are still a large amount of areas in the building that I'd venture to guess (so take with a grain of salt) would not require institutional heads and secure ceilings (employee offices).

I've been asked to install institutional sprinklers into non-secure ceilings and walls in the past (lights & HVAC were not any sort of institutional rated). Typically, these were not official correctional facilities, rather more local health care/mental health type occupancies.

When it comes to the state/federal funding of sites, the walls and ceilings are constructed to be more in line with security in mind but there are still areas like visitation rooms, adjoining bathrooms, meeting rooms, press areas that are hardened but not institutionally secured (expanded metal behind a wall/ceiling or Kevlar lined) that were requested to have institutional sprinklers installed.

If it were to go the other way, providing a less secure sprinkler into/through more secured construction type, I would make sure to have it in writing and responded to, including specific room names/numbers, wall types, and sprinkler types all noted so I would be covered (especially if an FPE or other EoR was assigned to Fire & Life Safety), we as contractors are often left making these decisions and holding the preverbal paper bag with the fan on.

Often times the operating entity of the correctional facility is also the AHJ. Think a county jail and a county AHJ, or a city police booking facility and city fire department. Having been on the AJ side as a fire marshal for a long time, it can be very convoluted. Its not the right hand not talking to the left - Its 5 fingers on the right hand telling the left hand what to do with different instructions. I highly recommend meeting with all of them, and get the path forward in writing.

Standard sprinklers should not be used in institutional (correctional-type) occupancy.

Early in my career I was tasked with how easy it was to damage a standard sprinkler versus an institutional sprinkler. I was able to break a glass bulb sprinkler within seconds.

Glenn, what are your thoughts on "inmate-accessible" areas? Cells seem to be very clear, but that term is in question for me.

Inmate accessible areas should use the same type of sprinklers as the cells themselves.

Have you considered some people in captivity kill themselves, that's why Institutional Sprinklers are considered and designed to be ligature resistant and I would not want that liability.

Institutional sprinklers are designed to break away if someone tries to hang themself. For this reason alone, I would not recommend installing standard sprinklers in institutional occupancies as the liability most certainly would fall upon the sprinkler company.

The interesting part here is the term "inmate-accessible." The cells are obvious - institutional sprinklers no ifs, ands, or buts. The term is a little confusing. There is no permanent occupation in these areas by inmates, but they can be in there. Inmates who are behaving well enough to have some duties could be in these spaces unoccupied though.

this is an issue to the authority that regulates the jail on a state or federal level there are regulations on the design that most owner would not have the authority to overrule.
