Fire suppression systems are used to suppress flames in the event of a fire. There are several types of suppression systems including wet sprinkler systems, dry sprinkler systems, deluge sprinkler systems and dry chemical suppression systems These systems work in conjunction with heat sensors, smoke detectors and fire alarm systems to improve and increase public safety. Fire suppression systems can help save lives and protect property from dangerous fires with a broad range of fire suppression solutions. Fire suppression systems are used to protect art treasures, architectural landmarks, oil tankers, data centers, factories, offices libraries, vehicles, and restaurants. The working principle of fire suppression systems differ for various types, though generally these systems employ a combination of the removal of oxygen and the lowering of the ignition temperature. Removal of fuel from an active area is seldom practical or even feasible. The most common method of fire suppression is the lowering of the ignition temperature with large quantities of water. Normal atmospheric oxygen content is approximately 21%. If the percentage falls below 15%, the quantity of oxygen available will no longer support combustion. Different types of fire suppression systems include vehicle fire suppression systems where mobile equipment serves all types of vehicles; restaurant fire suppression systems that mainly utilize portable liquid agent systems; dry fire suppression systems that extinguish fire by interrupting chemical reaction at the fire triangle; carbon dioxide systems that extinguish fire by removing oxygen and heat with a cold discharge; clean agent fire suppression systems that utilize halogenated extinguishers to suppress the fire by interrupting the chemical reaction at the fire triangle; water atomizing fire suppressing systems where a pair can produce 1.5 trillion water droplets per second equivalent to cover a soccer field in a minute; wet chemical fire suppression systems that prevent fire by creating a barrier between fuel and oxygen; dry chemical fire suppression systems that suppress fire by interrupting chemical reaction at the fire triangle; water and foam fire suppression systems that extinguish fire by taking away the heat and separating oxygen from other elements; inert fire suppression systems that utilize inert gases as agents, which are non-toxic, non- corrosive, and odorless, and dry powder fire suppression systems that extinguish fire by taking away the heat and separating oxygen from other elements. Unlike older types of fire suppression systems, current suppliers offer separate systems for specific fields of work. Also, the ease of handling, accessibility to fire suppression systems, and the percentage of useful assets that can be retrieved from an affected area are comparatively two to three folds than few decades ago. However, to suppress vast fire spots, pressurized water—with or without foams—is extensively used across the world. Fire suppression systems serve as life and property protection. Users should be well trained to use the equipment. Operating these systems without proper training can cause damage to the equipment, property, and people.
