This Plant is used for producing Cans
It consists of an oven and extrusion machine and painting machines (spray)
The Production Area = 3500 M2
The height of the Production Area is 11 m
The number of lines is 4 lines
What is the building safety code legally adopted by the AHJ? It will tell us what type of fire alarm system that is to be installed.
i'm from Egypt ,the factory is in construction stage , if i use a smoke detectors the oven and painting process will trigger it on .
If i use heat detectors the heat from oven will trigger it on as well
the hight of the windows is 5 m and the oven height is 4 meters .
What the best detectos type to use and where i shall put them .
I am not sure that a building safety code would mandate a partial or complete coverage by an automatic fire detection system to initiate a fire alarm here in the USA. The code below refers to "any" not "all". If you have a building code that says that the fire alarm initiation must be by an automatic fire alarm detection system, the choices for the detectors in the ambient conditions described are usually done by product tested by testing labs such as UL.
The mechanical codes might require the installation of duct smoke detectors when the supply or return volumetric airflow exceeds certain limits. The return side duct smoke detection is intended to prevent the re-circulation of smoke in a building.
In high-volume manufacturing and storage spaces, video image smoke and fire detection systems and highly sensitive smoke detection systems using special spot or air-sampling type detectors can be used to provide early detection. Projected beam smoke detectors also provide earlier detection than conventional smoke detectors, while being less prone to nuisance sources and easier to access, test and maintain. These systems can all be designed and deployed to provide variable signaling that depends on the conditions and the desired responses.
Excerpt from 2015 NFPA 101, Life Safety Code, Industrial Occupancy
40.3.4 Detection, Alarm, and Communications Systems.
22.214.171.124 General. A fire alarm system shall be required in accordance with Section 9.6 for industrial occupancies, unless the total occupant load of the building is under 100 persons and unless, of these, fewer than 25 persons are above or below the level of exit discharge.
126.96.36.199 Initiation. Initiation of the required fire alarm system shall be by any of the following means:
(1) Manual means in accordance with 188.8.131.52(1)(2) Approved automatic fire detection system in accordance with 184.108.40.206(2) throughout the building, plus a minimum of one manual fire alarm box in accordance with 220.127.116.11(3) Approved, supervised automatic sprinkler system in accordance with 18.104.22.168(3) throughout the building, plus a minimum of one manual fire alarm box in accordance with 22.214.171.124
Excerpt from NFPA 101- Storage Occupancy
126.96.36.199 Initiation. Initiation of the required fire alarm system shall be by any of the following means:
The quantities and types of materials might change the use classification from "industrial” to "storage” or to high hazard while NFPA codes would retain the occupancy designation, but impose additional requirements.
If you want to or have to have detection,,,
Use beam detectors
Does the building have a fire sprinkler system???
I have no idea what standards you are applying for ‘required’. Our service area included two large aluminum can beverage
plants. One, including storage, about 160k square feet. The other 400k square feet. The larger seldom, or never, had fires. The other regularly had fires in the ovens and vents from the varnish ovens. No sprinklers, the smaller plant probably wouldn’t have remained in business.
Hi, sorry for my poor speling in advance,NFPA 101, NFPA 5000, and NFPA 69 regulates the safty in industrial, storage high hazard buildings, if you have an color spray mashine or an oven, that would be a high hazard part of an proces.
In NFPA 101 is mandated local automatic fire extingushment like a lokal in oven automatic mist type or a gas like NOVEC, FM200 or simolar system, must be if there can't be an automatic sprinkler system do to reaction with water.
the beam detectors like Notifier type that is , when instaled auto calibrated for the normal conditions in the room when all mashinery is working, might be the answer for fire detection and alarm if you have a clear space over the mashinery without any obstructions like vent canals or similar.
