Fire alarm system in Curing area ?

[ROD10]

Hi everyone,

I'm reviewing a project of concrete and building material production. one of main process steps is curing process. this process achieved in a high humidity area with approximately 99%, and normal temperature degree. my question is: does such of this area need to provided with fire alarm and detection system (smoke or heat detectors)?

thank you,

Are you curing concrete? If not, what are curing? Does the curing process release chemical constituents to the atmosphere? If so, what are they?
Is the project in the US?

For the condition you described, neither conventional smoke or heat detection will work because your upper relative humidity exceeds the limits in NFPA 72. You may be able to use linear cable heat detection since it's listing is for about any noncorrosive atmosphere.

As to if the system is required, I don't know without more information.

Is this in the US?

What building or fire code and edition is the building designed to ?

Fire alarm in any other parts or is this a stand alone building?[pre][/pre]

How many sq ft

thanks all for your reaction. I'll try to answer all of your questions.
its not in Us. its curing concrete, but I' don't know if it release chemicals or not. there is a fire alarm system in the whole plant except this area.
the total area of curing process is around 5380 sq ft.
is there a need for ventilation or exhaust system in the same area?
thanks.

Given the size and activity in the building I see no need for a fire alarm and detection system other than asset protection. Even then this is a low risk activity.

If this is part of a main building / one building and the main building has a fire alarm system. Seems minimum the area would be required a/v's ????

If a stand alone than no

If you are curing concrete, let the room be in the condition that it is and there should be no need to ventilate until such time when the curing process is done and employees are expected to enter the room. Your heating system for this room is probably a direct fired steam generator which releases, into the room, steam and products of combustion for the curing process. I would suggest that when the doors are opened to let fresh air come in for a certain amount of time before anyone enters it. If you are uncertain as to how much time is needed to enter this curing room and you do use a direct fired steam generator, you should do oxygen and carbon dioxide tests to ensure that you are below the permissible exposure limits.
I worked for a company that made precast concrete products in the US. While the plant was sprinklered, the curing room which was attached to the plant, was not. We did have a direct fired steam generator and our employees never experienced illnesses related to O2 deprivation and CO2 poisoning, however, our employees would open the front and rear double doors for about 15 minutes to allow for adequate natural ventilation before entering.
