WET FIRE SPRINKLER SYSTEMS

The wet-pipe system employs automatic sprinklers attached to a piping system connected to a water supply . The water discharges immediately from sprinklers opened by a fire . Only those sprinklers which have been operated by heat over the fire will discharge water . This remains the most effective fire suppressor – though not for complex fires .

It is important to note that wet fire sprinkler systems require regular maintenance and inspection to ensure that they are functioning properly . This includes checking for leaks , rust , corrosion and other damage , as well as ensuring that the water supply is adequate .

DRY PIPE FIRE SUPPRESSION SYSTEM

A dry pipe fire suppression system is a type of fire sprinkler system that uses compressed air or nitrogen to keep the water in the pipes pressurised . The system only releases water when a sprinkler head opens , triggered by a heat detector sensing a fire .

Dry pipe systems are typically used in unheated areas or areas where the temperature may drop below freezing , such as a warehouse , garage or a parking structure . The compressed air or nitrogen maintains the pressure on the water , preventing freezing . Once a fire is detected , the heat activates a valve that releases the compressed air and allows the water to flow through the open sprinkler head , extinguishing the fire .

Dry pipe systems have several advantages over wet pipe systems . They are typically more efficient in preventing freezing and can be used in areas

where freezing is a concern . They also can provide an additional layer of protection by requiring a separate fire detection system to confirm the presence of fire before the sprinklers activate .

SPECIAL HAZARD FIRE PROTECTION SYSTEMS

Special hazard fire protection systems are a type of active fire protection system that is specifically designed to protect unique or specialised environments , such as data centers , cleanrooms or industrial processes . These systems are typically used in environments where traditional waterbased fire suppression systems would not be suitable or would cause damage . There are several types of special hazard fire protection systems , including :

• Inert gas systems : These systems use gases such as argon , nitrogen or carbon dioxide to extinguish fires by removing the oxygen necessary for combustion to occur .

• Clean agent systems : These systems use halocarbon or halon compounds
