Room Integrity Testing Service
Room integrity testing or RIT, is used to test the function of a gas operation system present in any room. It is important to check the proper functioning of a gas present system installed in the room to ensure that in case of a fire incident, it will work effectively to extinguish the fire.
How does it work:
In room integrity testing pressure is created in a room or the area where a gas suppression system is installed. Two things are measured in the room, one is the integrity of the room to make sure that the gas does not escape the room before extinguishing the fire. The second, thing to be checked is that the room is not packed too hard, to save the internal structure of the room from damage.
What is the minimum retention time:
It is ensured in the room integrity test that agent which has to extinguish the fire, will maintain the right concentration after attaining it, for a specific time period called ‘minimum retention time’.
BS EN 15004-1 suggests that the minimum retention time period of all gas fire extinguishing agents, should be ten minutes, but carbon dioxide should have a minimum retention time of twenty minutes. The fire should be properly extinguished, otherwise, there will be a chance of reignition of the fire.
So, a specific of an extinguishing agent should stay in the room for a specific time period. ‘Retention time’ is that specific time for which an extinguishing agent should stay in the room.
There is also a ‘minimum protected height’. Estimatedly, this height starts from the base of the floor to the top of the equipment. Also a ‘responsible person’ can refer the ‘minimum protected height’. One should consider the minimum protected height suggested by the ‘responsible person’.more
What type of systems need a Room Integrity testing:
FM200, NOVEC 1230, Co2, Inergen, IG55 and IG541, are the fire extinguishing systems that need room integrity test.
Tough sealing requirements for an effective minimum retention time of FM 200 are required because of its features. Other inert gases do not need such sealing requirements.
Generally, a room or any area which is protected by the FM 200 is required to seal and be sealed to prevent leakage almost by half of the other inert gases. This phenomenon affects the cost of structural sealing.
If Halon is the medium for an area or room, and it satisfies the room integrity test, then it will also satisfy the needs for other inert gases, without any addition to the cost of the structure. If the time with halon as a medium, increases than the 12.5 minutes then it will not meet the needs to contain FM-200 gas.
Then improvements in the structure of the building will be required which will definitely raise the cost of construction of a building.
How frequently a Room integrity test is required:
A gas suppression system extinguishes the fire and saves the environment from damage, therefore room integrity tests should be conducted regularly. British Standards (ISO14520 / BS EN15004) and NFPA 2001 Code suggests that room integrity test should be conducted before installation and after that at least once in a year. Also, after modifying the room, the room integrity test should be conducted.
What to do, if the room fails:
There is a chance of failing of room integrity test. If it happens the experts of Fire Safety Trading Pvt Ltd will provide a complete detailed report to their clients. Smoke is used to test the points of leakage. After identifying the points of leakage, they are sealed with the products which are used for sealing.
