Extinguishing Myths: The Truth About Fire Sprinkler Systems

Fire sprinkler systems are essential elements of the contemporary fire safety, however, they are still covered with the misconceptions that may compromise their significance. Hollywood fantasies and old fashioned suppositions about fire sprinklers tend to lower the adoption of the technology, which will save lives in case of fire.

This paper will attempt to dispel the myths and illuminate the facts about the fire sprinkler systems to bring out the best in their effectiveness, functionality, and worth in saving lives and property.

Myth 1: Every Sprinkler Fires Simultaneously.

The most widely-spread and ever-perpetuated myth, which movies tend to spread, is that once a fire sprinkler system is activated, all sprinkler heads in the building would go on at the same time, flooding the entire place. This theatrical representation is way out of the truth.

Fire sprinkler systems are specifically made or engineered and each sprinkler head is self-contained. Sprinklers are heat activated generally when temperatures reach between 135 o C and 165 o C. The sprinkler heads nearest to the fire will be the only ones that are activated and this will spray water close to the fire and contain the fire or put out the fire.

National fire protection association (NFPA) opines that, sprinklers, usually one or two are enough to manage a fire to reduce water consumption and destruction.

Myth 2: Fire Sprinklers do more damaging than the Fire.

The next myth is that fire sprinklers involve a lot of unnecessary damage by water thus being more destructive than the fire they are supposed to put out. As a matter of fact, fire sprinklers are designed to produce the least damage by reacting fast to a fire when it is in its initial phases.

An average sprinkler head releases approximately 10-25 gal of water in 1 hour, compared to 50-100 gal of water in 1 hour that is delivered by the hose of firefighters. Sprinklers prevent the vast walks of destruction of buildings, smoke, and poisonous heat that fires cause by suppressing or extinguishing a fire before it extends. NFPA studies indicate that propensities that have sprinkler systems have 85 percent less property damage than those with no sprinkler systems.

Myth 3: Smoke or minor sources of heat trigger sprinklers.

It is common among many individuals that a fire sprinkler is triggered by smoke, a burning candle or even a cigarette. This is not true. The fire sprinklers do not operate on smoke, but on heat. The sprinkler heads have a heat sensitive component (a glass bulb, loaded with liquid or a fusible metal connection) which melts or fractures at a particular temperature.

The daily chores such as cooking, smoking or lighting candles are not that hot to cause a sprinkler. This architecture will provide sprinklers with a minimal chance of accidental discharge by making sure that the sprinklers are only triggered when a real fire takes place.

Myth 4: Fire Sprinklers are commercial buildings only.

Although fire sprinklers are variously installed in most commercial and industrial structures, there is this fallacy that fire sprinklers do not or cannot be installed within residential premises. Home fire sprinkler systems are in actuality becoming more widespread and are very effective.

The NFPA reveals that the probability of perishing in a house fire is minimized by up 80% when sprinklers are installed. Residential sprinklers are developed with small area protection, and consume less water hence they are applicable in homes. They are easily fitted in new constructions or retrofitted into the existing homes thus assuring home owners peace of mind.

Myth 5: Fire sprinklers are expensive and difficult to maintain.

The problem of cost is usually used to deter property owners to install fire sprinkler systems, however, the truth is cheaper than they expect. Fire sprinkler system cost Fire sprinkler cost to a new building can be a matter of addition of 1-2 percent of the overall building cost, as stated by the Fire Protection Research Foundation.

Updating an existing building could be a more expensive undertaking, but this will be compensated in the possible savings of property damages and insurance coverage. Most insurance firms give 10 to 20 percent discounts on properties fitted with sprinklers. On maintenance, the sprinkler systems are long lasting and do not demand a lot of maintenance. The system is kept in operation through regular inspections which are normally done on a yearly basis by experts.

Myth 6: Fire Sprinklers do not work.

Other cynics doubt the effectiveness of fire sprinkler systems as they believe that the sprinklers will probably fail to work at the time they are most required. Nevertheless, statistics provided by the NFPA show that sprinkler systems have a very high reliability with a success rate of more than 95% in controlling or putting off fire given that the systems are well maintained.

Failure is not very often and is usually caused by faulty installation, poor maintenance or sabotage. Frequent testing coupled with compliance to NFPA standards, including the NFPA 13 standard of commercial systems and the NFPA 13D standard of residential systems, is essential in ensuring that the sprinklers work against type in the event of an emergency.

Myth 7: Fire sprinkler systems are all the same.

Fire sprinkler systems are not all equal. It has a number of types that are suited to other environments and fire threats such as wet pipe, dry pipe, pre-action and deluge systems. The most prevalent are the wet pipe systems that are filled with water and are directly discharged. Dry pipe systems that are applied in lower-temperature climates are also filled with pressurized air to avoid freezing.

Pre-action systems have two activation triggers (e.g., a smoke detector and heat) which is why they are most suitable in sensitive places such as data centers. Deluge systems release huge amount of water in high hazards. Knowing the exact requirements of a building can help to be sure that a proper system is placed to deal with maximum protection.

Myth 8: Fire Sprinklers are Obtrusive and Unsightly.

Aesthetics are another factor that discourages individuals to install fire sprinklers due to their perception of oversized industrial perception of the equipment. Contemporary sprinkler systems though are made discrete. Sprinkler heads may be integrated into walls or ceilings, and even the covers may be painted to match decor.

Sprinklers in residential places are usually small and designed to suit the beauty of the house. Quite on the contrary, these systems are not an eyesore because they do not affect the design.

The Fact: Fire Sprinkler Saves Lives and Properties.

The facts are undisputed: fire sprinkler systems have proven to be some of the best fire protection measures. They are much quicker than the fire departments, contain fires when they are at their initial stages, and considerably minimize the risk of injury, loss of life, and damage to properties.

The NFPA states that fire death rate in buildings equipped with sprinklers is 90 percent less than that in buildings equipped with the device. They also minimize the effects of fires to the environment by curtailing the smoke and the toxic emissions.

By debunking these myths, we can appreciate the true value of fire sprinkler systems. They are not only reliable and cost-effective but also adaptable to various settings, from homes to high-rise offices.

Investing in a fire sprinkler system is an investment in safety, offering peace of mind that lives and property are protected. Whether you’re a homeowner, business owner, or property manager, understanding the facts about fire sprinklers empowers you to make informed decisions about fire safety.
