What is FiFi system?
What is FiFi system?
An essential part of any preparation is to have fire-fighting (FiFi) equipment on support vessels. There are three categories of OSV fire-fighting systems. A FiFi 1 system is the basic level with two monitors, one to two pumps and capacity of 2,400 m3/hour, a throw length of 120m, and height of 45m.
How do you build a fire fighting system?
Five Steps to Fire Protection System Design Success
- Step 1: Achieving Compliance with Codes. What’s the first thing you need to consider when setting out to design a new fire protection system?
- Step 2: A Detection Solution.
- Step 3: Notifications and Alarms.
- Step 4: Fire Suppression.
- Step 5: System Maintenance.
What is FiFi class1?
FiFi class I is the most commonly used system with monitor capacity 2 x 1200 m_/h. Pump capacity will also include a deluge system and deck heads. Foam capability can be integrated as part of the system.
How does fire fighting work?
The pumps are controlled by pressure sensors. When a fire fighter opens a hydrant, or when a sprinkler comes on, water gushes out of the system and the pressure drops. The pressure sensors will detect this drop and switch the fire pumps on.
Which type of pump is used in fire fighting system?
Centrifugal pumps
Centrifugal pumps are the most common fire pumps and are used with most systems. With centrifugal pumps, pressure is developed principally by the action of centrifugal force or spinning. Water in centrifugal pumps enters the suction inlet and passes to the center of the impeller.
How many types of fire systems are there?
Intelligent Fire Alarm Systems are available in 2, 4, and 8 loop versions which means large premises can be monitored from one single panel.
What is hydrant & sprinkler system?
Fire Hydrant. Lines and Sprinkler. Systems Fire Hydrants, or hydrant outlets, are installed within the building to enable firefighters to connect their hoses to a water supply to fight fires.
What are two types of fire fighting system?
Fire-protection systems fall into two main categories — passive fire protection and active fire protection. Passive fire protection involves the use of building components to control or limit a fire. Walls, floors, and ceilings can be designed and constructed to resist the passage of fire and smoke.
Which pipe is used in fire fighting?
Fire sprinkler pipe and related fittings are generally made of carbon steel or ductile iron material and used to carry water or other liquid to connect firefighting equipment. It is also called fire protection pipe and fittings.
What are the classifications of fire fighting systems?
The Most Common Types of Fire Suppression Systems
- Water-Based Fire Suppression Systems. One of the most common types of fire protection systems uses water to knock out fires.
- Chemical Foam Suppression Systems.
- Pneumatic Heat Detection Tube.
- Pressurized Gas System.
- Foam Deluge Systems.
What is jockey pump?
A jockey pump is a small pump connected to a fire sprinkler system to maintain pressure in the sprinkler pipes. This is to ensure that if a fire-sprinkler is activated, there will be a pressure drop, which will be sensed by the fire pumps automatic controller, which will cause the fire pump to start.
What are types of fire protection systems?
What is the pressure of fire fighting system?
Wherever necessary, pressure reducing orifices shall be provided so as to limit the pressure to 3.5 kg/sqcm or any other rating as required by the local fire brigade.
Is code for external fire hydrant system?
Fire hydrants, namely, stand post type, conforming to IS 908: 1975 and underground type conforming to IS 909: 1975 should be provided. For use in industrial establishment, only stand post type hydrants should be provided.
