There are two main types of fire-protection systems: passive fire protection and active fire protection. Building components can be used as passive fire protection to contain or reduce a fire. It is possible to plan and build floors, ceilings, and walls so that smoke and fire cannot easily pass through them.
What are the various types of fire protection systems?
Common Fire Protection Systems
- Sprinkler systems for wet fires.
- Systems for dry pipes.
- Systems for Special Hazard Fire Protection.
- Fire suppression systems using dry chemicals.
- systems for suppressing gaseous fires.
- Systems to suppress fires with foam.

Burning flammable solids as fuel constitutes a class A fire. Paper and wood are a couple of examples of these. Flammable liquids burn in class B fires. Gas and paint are two examples.
What is the most common type of fire protection?
Water. The most popular kind of fire suppression system is one that uses water to put out fires, and most people decide to install them in commercial buildings.
What is fire protection systems?
Standard building components called fire protection systems either actively or passively aid in limiting the amount of damage that can be done to a structure and safeguarding its occupants in the event of a fire.
How many types of fire systems are there?
Large buildings can be monitored from a single panel thanks to the 2, 4, and 8 loop versions of intelligent fire alarm systems.
What are the components of fire protection system?

What are three basic types of fire detection systems?
Ionization, photoelectric, and hybrid ionization/photoelectric smoke detectors are the three types that are most frequently used. When they detect smoke, all smoke detectors sound an alarm to let building occupants know. The manner in which these detectors detect smoke sets them apart from one another.
Are sprinkler systems active or passive?
These systems can be either automatic, like a sprinkler system, or manual, like a fire extinguisher. Active fire protection systems include fire alarms, smoke detectors, and even firefighters.
Is fire hydrant passive or active?
The following systems make up active fire protection apparatus: systems for fire detection and alarm. systems for supplying water to fight fires. system of fire hydrants.
How many types fire pump?
Fire pumps of the horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction variety are frequently used in the fire service.
What is NFPA standard for sprinkler systems?
NFPA 13 is an installation standard; it does not list the types of structures or buildings that call for sprinkler systems. After it has been determined that a sprinkler system is necessary, NFPA 13 specifies how to properly design and install a sprinkler system using the appropriate parts and materials.
What are the 3 main causes of fire?
A fire requires an ignition source, a fuel source, and an oxygen source in order to ignite. For instance, if a smoker falls asleep holding a lit cigarette, the cigarette serves as the ignition source, the material of the sofa serves as the source of fuel, and the air serves as the source of oxygen.
How do fire systems work?
High heat activates the sprinkler system, which is how fire sprinklers function. The air directly above a fire heats up quickly as it burns. This heated air rises to the ceiling and spreads out. A chain of events begins when hot enough air reaches a sprinkler head.
What is a common fire alarm system?
system for alarming fires. 2.3. A fire alarm system that will sound an alarm in the event of a fire anywhere in the building, including inside every apartment and in the communal areas.
What are the main types of detectors?
The two main categories of detectors are thermal and photon detectors. All detectors share the following traits: A detector’s output must adapt to variations in the amount of incident light. Quantities like responsiveness, sensitivity, and dynamic range serve as indicators of a person’s capacity to react.
What is fire hydrant system?
In order to put out a fire, water can flow from a water main through a pipe known as a fire hydrant under the control of a valve. The Fire Hydrant Protection System is built to put out fires of all sizes and risk levels. In the event that a portion of the impacted structure collapses, it is still intended to function.
What are fire dampers used for?
Such penetrations and openings can be secured using fire dampers. A fire damper is made to stop airflow and prevent the spread of flames by automatically closing when heat is detected (using a fusible link or heat detector, for example).
What is CO2 fire extinguisher?
Excessive pressure is used to fill carbon dioxide extinguishers with non-flammable carbon dioxide gas. A CO2 extinguisher can be identified by its hard horn and absence of a pressure gauge. When you use one of these extinguishers, pieces of dry ice may shoot out the horn due to the high pressure inside the cylinder.
What are examples of active fire protection systems?
Hoses, water spray, deluge, sprinklers, firewater monitors, and steam rings around flanges are examples of active fire protection systems. Water is typically the main firefighting tool. Other substances, like carbon dioxide, can also be used.
Are sprinklers active fire protection?
In the process industries, storage vessels, process plants, loading installations, and warehouses are all protected by active fire protection systems like water sprinkler and spray systems.
Which chemical is used in ABC type fire extinguisher?
Fire extinguishers marked “ABC” are stocked at USC with a fine yellow powder. The monoammonium phosphate makes up the majority of this powder. The extinguishers are pressurized using nitrogen.
How many types of sprinklers are there?
All fire sprinklers fall into one of four categories: concealed, sidewall, upright, or pendent.
What are the different types of sprinklers?
Let’s discuss four types of sprinkler systems and their best uses.
- Commercial sprinkler system with wet pipes. Wet pipe systems have overhead piping that is pressurized with water.
- Commercial sprinkler system with dry pipes.
- Commercial sprinkler system with pre-action.
- Commercial Foam Water Sprinkler System.
What is the pressure of fire pump?
Manufacturers rate fire pumps to generate a specific net pressure (typically between 40 and 250 psi) at their rated flow.
What is capacity of fire pump?
3-10 hp Electric High Pressure Fire Pump, Capacity: Up to 1100 m3/hr
|Head||upto 100 m|
|Capacity||up to 1100 m3/hr|
|Temperature||350 deg C|
Does OSHA require sprinkler systems?
To be more precise, OSHA mandates that sprinkler systems be tested and inspected annually to guarantee that they will function properly in the event of a fire. These inspections are designed to make sure that sprinkler systems will put out fires as effectively as possible.
What is the minimum pressure on one sprinkler head as required by NFPA 13?
Even when the calculation process results in a lower value, NFPA 13 specifies a minimum pressure of 7 psi. By doing this, sprinklers will produce the proper spray pattern.
What 3 items are in a fire safety plan?

What are the 3 goals of fire prevention?
The objectives of fire-prevention programs include avoiding fatalities, property loss, and building inactivity.
What is the fire triangle?
The “fire triangle.” is a term used frequently to describe oxygen, heat, and fuel. A fire “tetrahedron.” actually exists when the chemical reaction, the fourth element, is added. The key point to keep in mind is that if you remove any one of these four items, there won’t be a fire or it will be put out.
What is fire and types of fire?
categories of fire. Class A fires are those that involve solid objects, like wood, paper, or textiles. Class B fires are those caused by flammable liquids like gasoline, diesel, or oils. Gas fires fall under class C. Metals-related fires fall under class D.
Which pipe is used in fire fighting?
Although steel has traditionally been the material of choice for fire fighting pipes, thermoplastic pipes are now also offered for use in residential and commercial settings.
What temperature do sprinkler heads activate?
What actually activates fire sprinklers? The technology behind fire sprinkler systems is quite advanced, and the sprinklers are built to be heat-sensitive, only turning on when the temperature reaches a fire-induced level, typically between 155 and 165 degrees Fahrenheit.
