What is the requirement of water supply in factory for firefighting?
It is recommended that generally for towns/cities, water for fire fighting shall be provided at the scale of 1800-l/min for every 50 000 population or part thereof for towns up to 3 lacs population and an additional 1800-l/min for every 1 lac population of more than 3 lacs.
What is water based fire protection system?
The system is a water based system consisting of water tank, suction piping, fire pumps and a distributed piping network. The distributed piping system establishes connectivity throughout the building through fire hydrants, hoses and nozzles. This helps in controlling fire during an emergency.
What type of water is supplied to an automatic fire sprinkler system?
Public/private water supply mains The most common and least expensive water source for sprinkler systems is the public water supply system. If the public water supply is the only source of water for the sprinkler system, it must be reliable and maintain adequate pressure and volume at all times.
What are the methods of fire protection?
Common Fire Protection Systems
- Wet Fire Sprinkler Systems.
- Dry Pipe Systems.
- Special Hazard Fire Protection Systems.
- Dry Chemical Fire Suppression Systems.
- Gaseous Fire Suppression Systems.
- Foam Fire Suppression Systems.
How much water does a firefighter need?

How much water requires per head per day for fire fighting?
Water Consumption Rate
| Types of Consumption | Normal Range (lit/capita/day) | |
|---|---|---|
| 1 | Domestic Consumption | 65-300 |
| 2 | Industrial and Commercial Demand | 45-450 |

What is water based systems?
Water-based systems are used for protecting fire scenarios where the main hazard is fire spread caused primarily by thermal radiation. Typical water-based fire-fighting systems are Deluge Systems, dry pipe and wet pipe fire Sprinkler Systems, or Preaction Systems, hybrids of deluge and sprinkler systems.
What is water suppression system?
Water spray nozzles are designed to spray water directly onto the hazard surface via a series of nozzles with a carefully predetermined spray pattern. In this way, Water Mist combines the fire suppression properties of both conventional water-based deluge or sprinkler systems and gaseous fire suppression systems.
Which liquid is used in fire sprinkler bulb?
Fire sprinklers are triggered once they reach a certain temperature, which is detected with the help of a glass bulb. The bulb is filled with a glycerin-based liquid that expands and breaks the bulb once a specified temperature is reached.
What is a Siamese valve?
A siamese connection or splitter in fire protection engineering is a pipe fitting that allows two or more fire hoses to be connected to a single standpipe riser at the same general location. It is so-called due to the visual similarity to siamese twins.
What is the most common type of fire protection equipment?
Water. A fire suppression system that relies on water is the most common type of fire suppression system, and most people choose to have them installed in businesses and buildings.
What are three 3 rules for preventing fires?
That’s why it’s important to be prepared and take steps to reduce the risk of a house fire. Follow the three P’s: prevent, plan and practice. Make sure your home has working smoke alarms, your family has a fire escape plan, and you have practiced it.
How are water tanks used in fire protection systems?
A system that is designed without taking into account fluctuations in the water supply could result in insufficient pressures or over pressurization of the system. Water storage tanks are tanks that supply water for water-based fire protection systems.
How does a fire service water supply work?
A water supply shall consist of reservoirs, pressure tanks, elevated tanks, water mains or other fixed systems capable of providing the required fire flow. Private fire service mains and appurtenances shall be installed in accordance with NFPA 24. Water tanks for private fire protection shall be installed in accordance with NFPA 22.
When to test water supply for fire protection?
The water supply tested should represent the supply that might be available at the time of a fire (in other words, at times of highest demand on the waterworks system and at times of the lowest demand on the waterworks system).
Where does water come from for fire protection?
Naturally occurring sources include penstocks, flumes, rivers, ponds, and lakes. Water supply sources such as these must be arranged to avoid mud and sediment being introduced into the fire protection system piping. These are thus required to include double removable screens or strainers on the water piping intakes.
