Fire safety is one of the core elements in any building: it could be a residential area, commercial building, or an industrial facility. The danger of fire can strike at any time, and the outcome can be dangerous. According to the National Fire Protection Association, thousands of injuries and deaths occur each year due to fires. Automatic fire extinguishers are the most effective preventive measures for preventing fires in an area. In this article, we’ll have a look at how an automatic fire extinguisher works, as well as the advantages of putting one in place and the reasons why it’s a crucial aspect of any plan for fire safety.
Automatic fire extinguishers detect fires at the earliest stage and suppress them. These devices minimize damage and loss of life. They are mounted in places susceptible to catching fire, such as kitchens, electrical rooms, and storage places. Since fire extinguishers that require human intervention, an automatic fire extinguisher responds quickly and effectively, at times before fire spreads.
It is not a question of whether one complies but life versus death. Fires can be due to electrical malfunction, arson, or just plain human error. The effects after the fire may be devastating in most cases, culminating in loss of life, property damage, and business interruption. Installing automatic fire extinguishers essentially means that building owners and managers can greatly decrease the chances of fire happening.
Automatic extinguishers fire instantly and automatically in case of a fire. But how do they work? Let’s get closer to the detection and activation processes.
Automatic fire extinguishers come very highly equipped with a detection system that can detect the early signs of a fire. Often, it is made of heat detectors, smoke detectors, or optical detectors continuously scanning their surrounding environment for indications of fire and activating the extinguisher to release the suppression agent on sensing the fire.
The central content of an automatic fire extinguisher is the suppression agent. The supposed action of this agent is to smother the fire by denying it the oxygen so that it cannot be spread. The kind of suppression applied also depends on the nature of the fire and the environment in which the extinguisher is located.
There are various types of automatic fire extinguishers, each fighting a different type of fire. Let’s discuss some of the most common types of automatic fire extinguishers.
Water-based extinguishers are suitable for Class A fires, which are fires involving ordinary combustible materials like paper, wood, and cloth. They release a water-based agent that cools the fuel and thereby removes the heat source.
Gas extinguishers are designed to combat class B fires, which comprises flammable liquids and gases. These extinguishers release the gas-based agent that displaces oxygen and thereby starves the fire of oxygen to smother it.
Dry chemical extinguishers are all-round extinguishers and can be used to combat class A, B, and C fires. The agent released by these extinguishers separates the fuel from oxygen, thereby curtailing the spread of the fire.
Automatic fire extinguishers have loads of advantages that make them vital in any fire safety plan.
The Automatic fire extinguishers respond very fast usually in minutes. This fast response time is crucial in preventing the spread of fires and minimizing damage.
Traditional fire extinguishers depend on human reaction, and their response is open to human error and delay. Automatic fire extinguishers don’t have to rely on human error; otherwise, they can respond as soon as possible with maximum effectiveness.
The employment of automatic fire extinguishers helps reduce costs in fire damage, as well as what may be caused by the business disruption. The response may be faster, as well as more efficient, resulting in lesser damage and minutes lost in downtime.
Automatic fire extinguishers need to be installed and serviced correctly to achieve the best usage and effectiveness. Automatic fire extinguishers should be installed according to the local regulations and guidelines. One should ensure that the extinguisher installed is in an area prone to fires and accessible easily.
Routine inspection is mandatory to ensure that the automatic fire extinguisher operates effectively. Such inspections must be performed by experts and should cover detections, testing, and maintenance of the detection system and suppression agent.
Selection of the appropriate automatic fire extinguisher is quite challenging since there exist too many variants.
In this regard, the first step in choosing a good automatic fire extinguisher is to carry out an assessment of the risks posed by fires within your building. This involves identifying areas where fire most probably may occur and what kind of fire may be involved.
After carrying out an assessment of the risks, the right type of automatic fire extinguisher can be chosen. This will take into consideration factors such as the type of fire to be extinguished, the environment, and the suppression agent.
Automatic fire extinguishers have averted fire outbreaks and minimized damage to several degrees. Let’s consider some case studies about automatic fire extinguishers in practice.
