Let’s begin by summarizing the options of every kind of computerized fireplace suppression system utilized in most information facilities, NOCs and server rooms right this moment. Then, I will get into specifics that you’ll want to contemplate earlier than selecting fireplace suppression tools and a fireplace suppression firm.

First, Perceive the Sorts of Fires You May Encounter

The Nationwide Fireplace Safety Affiliation has labeled fires into 4 varieties, decided by the supplies or gasoline being burned:

Sort A: Fires with flamable supplies as its supply, similar to wooden, material, paper, rubber, and plenty of plastics

Sort B: Fires in flammable liquids, oils, greases, tars, oil-base paints, lacquers, and flammable gases

Sort C: Fires that contain electrical tools

Sort D: Fires with ignitable metals as its gasoline supply

In a typical server room fireplace, a mix of Sorts A, B and C could be discovered. An efficient fireplace suppression system might be rated for all three varieties.

Usually the supply of a fireplace in a server room just isn’t detected till after the hearth has been extinguished. Subsequently, putting in a system that may deal with A, B & C Sorts is a safeguard towards an sudden catastrophe.

Substances Utilized in Fireplace Suppression: Fuel, Water and Aerosol

1. Gaseous or Clear Agent Fireplace Suppression

Gasses utilized in fireplace suppression techniques are sometimes Halon, CO2 or environmentally-friendly clear brokers similar to Inergen. These gases don’t extinguish a fireplace by smothering it, however quite by displacing oxygen or inhibiting a chemical response that’s important to the hearth’s survival.

The favored fireplace suppressant Halon is so detrimental to the surroundings that each Europe and the USA banned manufacturing of the gasoline in 1995. It’s talked about right here solely as a result of many Halon techniques put in earlier than the ban was enacted are nonetheless in operation.

The U.S. Environmental Safety Company (US EPA) encourages using non-ozone depleting fireplace suppression agent options, and in 1990, the US EPA established its Vital New Alternate options Coverage (SNAP) to guage new chemical substances and applied sciences for the alternative of ozone depleting substances. Consequently, many corporations are putting in various clear brokers which are environmentally pleasant.

Clear brokers derive their title from the straightforward concept that they don’t go away any residue after discharge. This function makes them very best for electronics and eliminates cleanup worries.

One other gasoline utilized in fireplace suppression, CO2, is dangerous when inhaled at excessive concentrations (higher than 5% by quantity, or 50,000 ppm). The present threshold restrict worth (TLV) or most stage that’s thought of protected for wholesome adults for an eight-hour work day is zero.5% (5,000 ppm). For that reason, your facility should be vacated earlier than the system discharges.

In contrast to CO2, Inergen is non-toxic. Nevertheless, a discharge of Inergen leads to an approximate three% focus of carbon dioxide. Whereas initially breathable, it is strongly recommended that the surroundings be evacuated. Since it isn’t a liquid below stress, Inergen requires important space for storing. After a discharge, the surroundings turns into extremely pressurized which may trigger injury if not launched in a well timed method.

Fuel fireplace suppression techniques sometimes encompass the agent (gasoline), agent storage containers, agent launch valves, fireplace detectors and warning mechanisms, agent piping, and agent dispersion nozzles. With most gasoline brokers, the surroundings should be pressurized with a purpose to include the agent. Set up is advanced and expensive, and the reward is realized solely after discharge, as clear up is so simple as venting the room.

2. Water-Based mostly Fireplace Suppression

Water Mist Fireplace Suppression Methods resulted from the evolution from customary sprinklers designed for flooding fires. A lot lighter than their older counterpart, water mist techniques are efficient on Sort A and B fires and lead to much less injury than conventional water-based techniques. Nonetheless, water mist techniques should not very best for server rooms as a result of Sort C electrical fires widespread to this surroundings. Clear up and questions of safety are additionally a priority when confronted with moist or damp electronics. Though efficient in the appropriate conditions, water mist techniques should typically be augmented with different fireplace suppression techniques with a purpose to guarantee full protection within the occasion of a fireplace. After discharge, count on down time of some weeks for a sprinkler system and fewer with water mist. Usually with a sprinkler system, you might be unable to take it with you in case you are in a lease or are planning to maneuver to new services. This might make a giant distinction in your consideration of a water-based system.

three. Aerosol Fireplace Suppression

The most recent expertise in fireplace suppression, Aerosol Extinguishing Know-how, was formally accepted and efficient in 2005 by the Nationwide Fireplace Safety Affiliation. A clear agent with no submit combustion byproducts, aerosols such because the model Aero-Ok don’t substitute the oxygen as CO2 does, don’t produce Hydrofluoric Acid (HF) after the hearth, and haven’t any environmental affect.

The aerosol consists of ultra-fine particles which are expelled through mills. Upon discharge, the substance creates a fog of suspended particles. Non-toxic and non-corrosive, the agent stays suspended within the surroundings for as much as 60 minutes, nearly eliminating any risk of reignition. After discharge and a 10-minute maintain time, clear up consists of venting the room and a light-weight dusting of the surfaces.

In contrast to gaseous techniques, which function at stress and sometimes require in depth piping, aerosol mills are very price efficient to put in and keep and have minimal house and weight necessities. The mills that dispense the aerosol can be found in a wide range of sizes to accommodate any measurement surroundings.

Choose A Fireplace Suppression System with Reliable Security Options

Security options can save time, cash, tools, and most significantly, lives. Listed below are some options that your fireplace suppression system should have with a purpose to stop both untimely discharge or the alternative – activation delay – when a brand new fireplace is both seen or by chance began by human error.

Lock Out/Abort Change –This function is crucial for cases when a service particular person is within the protected surroundings and creates smoke, for instance from soldering. A lock out/abort change enables you to disable the system with a key to keep away from an unintended discharge. Ought to a threatening fireplace begin whereas the system is disabled, a employee can use a fireplace extinguisher for a localized fireplace or arm the system and use the guide pull station.

Handbook Pull Station –If a fireplace is inadvertently began, or is seen by somebody within the room, the guide pull station permits for quick discharge with out ready for the system to detect smoke.

An Automated Fireplace Suppression System Can Decrease Your Insurance coverage Premium

When you do not at the moment have a fireplace suppression system, contemplate the insurance coverage price financial savings. Insurance coverage corporations typically supply a Loss Management Survey that, when accomplished, might supply price reductions for putting in a waterless or dry chemical fireplace suppression system. A name to your agent and a few comparative procuring provides you with an thought of what you may save – sometimes within the vary of 10%-15%. Remember to take the tax deduction. With a 10-year shelf life, a product similar to Aero-Ok could be depreciated over its full helpful life.
