Fire Gas Horn

Things you need to know about Fire Gas Horns

In case of fire or any kind of emergency situation in buildings or homes, the sound of a fire alarm is sufficient enough to attract other people’s attention and inform them of the situation. But what if you are in a remote area or within a noisy environment such as a factory, or in a wide open space where the mere sound of the fire alarm won’t be able to attract the attention of other individuals, what fire safety equipment do you need to inform them of the ongoing emergency situation? It’s simple, you just need to use a fire gas horn.

In the United Kingdom, the law is very strict with regards to fire safety regulations and you won’t get a favorable decision on your fire risk assessment if you are caught not using even one of the required fire safety equipment like the Dorgard, exit stopper, fire and smoke seals, fire exit signs, or even a fire gas horn.

In the old days, horns are commonly used in sporting, hunting, and some rescue operations.

In general, horns are classified into two distinct types:

1. The electrical siren which uses electrical energy or electricity for it to be able to produce sound. The sound is produced when the diaphragm is moved back and forth by an electromagnetic device when electricity passes through it.

2. The air horn on the other hand uses compressed air to produce sound. The gases used may be compressed air or any other type of compressed gas combinations.

A fire gas horn is classified under the air horn type. A hand-held fire gas horn operates through the use of a compressed gas that is released from a highly pressurized canister. All in all, each of these commonly used gasses and gas compositions or mixtures are referred to as either gas or air and that is where the fire gas horn got its name because it uses compressed air to produce sound and it is commonly used to attract attention in the event of a fire.

Usually, air horns requires a trumpet-type fixture which operates in partnership with an actuator button and a cone-shaped trumpet nozzle which emits a loud horn blast when the compressed air is released from the canister and through the trumpet fixture.

Hand-held air horns typically have a limited capacity and this coincides with the dimensions or the size of the canister. A design of an air horn device is rather complicated because of numerous mechanical components which include the canister, trumpet nozzle and the required seals that helps prevent gas leaks. Fire gas horns have been used for generation as a loud announcement of some signal or an indication of an emergency.

The advantage of a fire gas horn against the electrical siren is that it is portable. It is also a feasible option in the absence of any electrical power sources or anything that produces electricity that is needed by fire alarms or electrical sirens for them to be able to produce sound.
