Fire suppression systems are divided into two categories: active and passive. Active systems use chemicals to put out fires, while passive systems don’t use chemicals. They can consist of smoke control systems, automatic sprinklers, or other types of passive fire suppression systems. Passive systems are typically built into buildings, though some may be more effective than others. Passive systems can also include smoke and fire curtains, which combine active and passive features. After fire detection, fire curtains can be deployed, becoming a passive part of a fire suppression system.
Active and passive fire protection systems
There are two types of fire protection systems: passive and active. Passive systems are in place when a fire begins, but they aren’t necessarily visible to the untrained eye. Active systems are designed to contain a fire, and passive systems are designed to help occupants escape safely when a fire does occur. Keeping these systems in good repair and working properly will help keep a fire from spreading. But what’s the difference between passive and active fire protection systems?
Fire-alarm systems are part of active fire protection. These systems detect smoke or heat, activate extinguishing systems, and alert fire officials and the occupants of a building. Smoke control systems limit the spread of smoke and prevent fire from spreading through the building. Fire alarm systems may also activate smoke-control systems and activate automatic detection devices. Fire sprinklers are typically used in combination with an automatic detection device.

Chemicals used in fire suppression
There are two types of chemical extinguishers: dry chemical systems and wet chemical systems. Dry chemical systems use a powdered chemical such as sodium bicarbonate or mono-ammonium phosphate to put out a fire. Dry chemical systems are typically pressurized tanks that are opened by a high-pressure nitrogen cartridge, which releases the powder into the piping. They must be recharged before they can be used again.
These chemicals are used on a variety of fires and are classified according to their chemical phase and mechanism of action. They are also classified by their mode of application. Water is the most commonly used fire suppressant because of its affordability and non-toxicity, but can be highly toxic when diluted. Powdered chemical agents are used on Class B and C fires. Both of these agents can withstand high temperatures but can be difficult to treat once used.
Smoke control systems
Fire protection systems come in several forms, including smoke control systems. Passive smoke control systems use partitions or barriers to contain smoke. Active smoke control systems use airflow or pressurization to restrict the movement of smoke in certain areas. The use of these systems provides occupants with additional time to evacuate a building or to evacuate themselves. In most cases, smoke control systems are installed in a building’s atria.
Depending on the nature of the space, smoke control systems may be required by the International Building Code for certain types of buildings. These systems are typically required in large-volume areas, such as shopping malls, theaters, airport terminals, sports arenas, and entrance lobbies. Smoke control systems may also be required in compartmentalized spaces. NFPA 92 specifies the installation and performance requirements for smoke control systems, including how they should be installed and tested.
Automatic sprinkler systems
There are several factors to consider before selecting an automatic fire sprinkler system. In addition to the codes and standards that are in effect in your area, there are other factors to consider such as the layout and risk factors of your building. These factors will impact the design of the sprinkler system and the components of the system. Fortunately, some guidelines can help you choose the best automatic sprinkler system for your building.
Dry pipe sprinkler systems use a piping system filled with air, which is at a lower pressure than the water supply. This prevents premature water induction, which can damage expensive electronics. Another benefit to dry pipe sprinklers is that water remains in the system until an automatic fire sprinkler head activates. This makes the fire sprinkler system more effective in protecting expensive electronic systems in museums and other valuable objects.
Gaseous clean agents
There are two main types of fire fighting system available in the marketplace today: chemical and gaseous. These agents are based on the same basic principles: they do not ignite or burn. This makes them a sustainable option, and they are safe for personnel and the environment. Gaseous clean agents have a 20-year warranty and can contribute to LEED Innovation credits. Listed below are the benefits and disadvantages of both types of systems.
Conclusion
Clean agents are chemical compounds that disperse when they are applied to a fire. They work by absorbing the heat generated by the fire and leaving no residue behind. Unlike water-based systems, chemical clean agents do not harm delicate electrical components or other equipment. They are also less expensive to install and require fewer hardware components. In addition, they work better in occupied spaces. There are many benefits of using chemical clean agents.
