- Fire Extinguisher
Fire extinguisher, or extinguisher, is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure containing an agent which can be discharged to extinguish a fire.
- Fire Hydrant System
Fire hydrant pump systems (also known as fire pumps, hydrant boosters, fire water pumps) are high pressure water pumps designed to increase the firefighting capacity of a building by boosting the pressure in the hydrant service when mains is not enough, or when tank fed.
Types of Fire Hydrant System
A fire hydrant is a connection point to a water main from which water may be taken for firefighting purposes. On an underground main the hydrant outlet and valve may take the form of an above ground pillar or be located in an underground pit beneath a cover plate, necessitating the use of a stand pipe.
For a fire main within a building outlets (landing valves) will comprise of direct hose connections with associated isolating valves. A fire hydrant system will be provided for the purpose of the direct connection and use of hose lines for firefighting. A supply to mobile pumps that boost the pressure to the required magnitude to supply firefighting hose lines.
Defining this purpose is a key factor in specifying the hydrant outlet pressure and flow performance criteria. The water supply to a hydrant system may be from a public water supply (town’s main) or a private supply via pumps from a stored water source.
Advantages of Fire Hydrant System
- Available water supply and storage –this can be from street main water pipes, a static water tank or a dam. There should be some form of automatic replenishment of any water that is used, evaporates or leaks. Consider the capacity of the water supply and whether it would be adequate to address a large fire.
- Valves and connecting pipes –the pipes and valves should allow water to flow from the water reservoir to the hydrant area without restrictions. The size of the pipes and valves should be determined based on the water supply requirements and a hydraulic analysis along with Australian Standards guidelines from AS2419.
- Fire Brigade Booster –this assembly will allow a quick and easy connection for the fire brigade equipment to pump additional water into the hydrant. In normal installations the booster is located in a cabinet and notes any pressure specifications in accordance with the fire hydrant system.
- Booster Pump set –this piece of equipment can be used where there are hydraulic limitations and additional pressure is needed to deliver adequate water supply. The pump set can be an electric motor or a diesel engine, depending on the requirements for the location.
- Hydrant –this is the part of the system that connects fire hoses to the water supply and has a valve to turn the water on or off when needed. The location of the hydrants should be determined based on Australian Standard AS2419, which will specify easily accessible locations to attack any fires quickly.
- Fire Hose –Depending on the building design and hydrant accessibility, there could be some situations that require a lay flat fire hose to be placed near the hydrant. This will allow quick connectivity and extended reach if needed for a fire emergency.
- Block Plan –Located in the booster cabinet, pump room and fire control room should be a block plan diagram that clearly illustrates the locations of fire hydrants, water supplies, and other equipment along with capacities where applicable. Other key information such as year of installation, contractor names and other items are also included in the block plan.
