Fire Fighting Equipments

Operation of Fire Hydrant
• The fire hydrant system installed at the centre opens when the operating valve is turned in the counter-clockwise direction.
• The hydrant valve opens downward against the flow of water. Opening a hydrant too quickly can cause a sudden decrease in pressure that could create a vacuum in the distribution system; back-siphonage may occur.
• Always open and close hydrants slowly.

Fire Suppression Systems
• Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring.
• Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different applications being used today. Of these, there are some that are still in use but are no longer legal to manufacture and produce.
• The basic components of a fire protection system include detection methods, alarms and notification devices, control panels, power supplies, the release mechanisms, and the suppressants themselves.
Here’s the rundown:
• Fire Alarm Initiation Devices: When a fire is detected, the initiation devices activate the fire suppression system. Some systems require manual initiation by a person in the facility, while others activate automatically. A direct release system will automatically trigger at a certain temperature or in the presence of fire. An indirect release system can be automatically triggered or activated by another means of a detection system.
• Fire Notification Devices: Notify people in the building that there is a fire. These typically include alarms, bells, horns, or other sounds and strobe lights. Always look for illuminated exit signs and pathways to evacuate safely.
• Alarm Monitoring Systems: These optional components integrate with the systems of local fire departments to automatically notify them when an alarm is triggered at the location.
• Alarm Control Panels: These allow the fire alarm to be turned off once it is triggered. In some cases, only the fire department can turn off the alarm after confirming the fire is extinguished.
• Suppressant Delivery Systems: Includes the water, chemical clean agents, and/or gases that suppress the fire, the pipes or tubes that carry the suppressant, and the release mechanisms like nozzles, sprinklers, or temperature-sensitive tubes.
• Primary and Backup Power Supplies: Some systems are hard-wired into the building's electrical infrastructure, while others rely on external power. Backup power supplies such as batteries are recommended for systems that require electricity.
• Fire Alarm System: A building system designed to detect, alert occupants, and notify emergency forces of fire, smoke, carbon monoxide, or other fire-related emergencies. Required in most commercial buildings, these systems may include smoke detectors, heat detectors, and manual fire alarm activation devices (pull stations). Components are connected to a fire alarm control panel, often located in an electrical or panel room. Fire alarm systems generally use visual and audio signals and may disable elevators, which are unsafe to use during a fire.
