Engineered fire suppression systems are design specific and most commonly used for larger installations where the system is designed for a particular application. Examples include large marine and land vehicle applications, server rooms, public and private buildings, industrial paint lines, dip tanks and electrical switch rooms. Engineered systems use a number of gaseous or solid agents with many of them being specifically formulated. Some are even stored as a liquid and discharged as a gas.

• Pre-engineered fire suppression systems use pre-designed elements to eliminate the need for engineering work beyond the original product design. Typical industrial solutions use a wet or dry chemical agent, such as potassium carbonate or monoammonium phosphate (MAP), to protect relatively smaller spaces such as distribution boards, battery rooms, engine bays, wind turbines, hazardous goods and other storage areas. A number of residential designs have also emerged that typically employ water mist and target retrofit applications.

How does Fire Suppresson system will work?

A fire repression system will have erected- in factors to descry fires as early as possible. These factors will first identify the presence of dears and bank. The repression system will also initiate an alarm, so the blaze can be subdued before it has the chance to spread. A fire repression system can be considered an ‘ active ’ fire protection system because the system is touched off in response to the presence of fire. As will be explored further in this composition, a fire repression system also contains a range of factors that ‘ laboriously ’ work to extinguish dears and bank. 

 TYPES OF FIRE 

Fires can be classified into different types based on the materials involved and the nature of the combustion process. The most common classification system for fires is based on the NFPA 704 standard, which uses a color-coded diamond with four quadrants. Here are the four main types of fires.

1- Class A Fire: These fires involve ordinary combustible materials such as wood, paper, cloth, rubber, and many plastics. Class A fires typically leave behind ashes and usually respond well to water or other common firefighting agents. 

2- Class B Fire: Class B fires involve flammable liquids or gases, including gasoline, oil, grease, propane, butane, and various chemical solvents. These fires can spread rapidly and be extinguished by smothering them or using dry chemical or foam-based extinguishers specifically designed for flammable liquid fires.

3- Class C Fire: This type of fire involves energized electrical equipment, such as appliances, wiring, circuit breakers, and electrical outlets. Class C fires can be extremely dangerous due to the risk of electric shock. The first priority is to shut off the power source, and then carbon dioxide or dry chemical extinguishers can be used to put out the fire.

Class D Fire: Class D fires involve combustible metals, such as magnesium, titanium, potassium, sodium, and lithium. These fires require special extinguishing agents, such as dry powder agents specifically designed for metal fires. Water or other common firefighting agents can react violently with certain metal fires, exacerbating the situation.

It's worth noting that there are additional fire classifications beyond the NFPA 704 standard, such as Class K fires for kitchen fires involving cooking oils and fats. Also, certain types of fires, such as wildfires (Class G), may have their own specific characteristics and methods of control.
