Active fire protection is a group of fire protection systems that require some action or motion to initiate the system in the event of a fire. The action that results from active fire protection is initiated by some sort of alert or signal. The action itself will help contain, suppress, or extinguish a fire that has already started.
Active fire protection systems such as water sprinkler and spray systems are widely used in the process industries for protection of storage vessels, process plant, loading installations and warehouses.
By definition, active systems require to be switched on, either by manual or automatic means, to be effective. The most common forms of active fire protection
Active Fire Protection is one of the HSE Critical (HSECES) aspects of facilities, meaning that systems performing this objective require specific focus during their lifecycle (design, procurement, installation, commissioning, operations & maintenance).
A fire hazard assessment will determine the type of active fire protection system that will be required against escalation of a fire for process structures and related facility.
This will ensure there is a clear understanding of the nature of potential fires and their location on the facility is known before decisions are made about the AFP systems most suitable to tackle them.
An active fire protection system is a dormant system that needs to be activated in the case of a fire to perform its function (activation of water spray systems, deluge systems, sprinkler systems, fire water monitors, and gas-based fire suppression inside buildings).
Common systems include fire water pumps, fire hydrants, monitors and hose reels for manual applications, and automatic water spray and deluge fire protection or water exposure cooling systems.
Fire Water Demand: It involved estimating quantity of water needed to suppress a fire in a particular area or facility. Calculating fire water demand involves considering factors such as the size and type fire potential equipment (i.e. Storage tanks, pressure vessel, transformer, pumps), potential fire hazards, occupancy, fire protection systems in place, and local fire safety regulations.
Fire water Hydraulic Study: Fire water hydraulic studies are essential for designing effective fire protection systems in industrial and commercial settings. This study assess the water supply's capacity and pressure needed to meet fire flow demands, ensuring that firefighting systems can operate efficiently. By simulating various scenarios, Aura veritas’s Fire protection expert can determine optimal pipe sizes, pump requirements, and layout configurations.
It includes performing network hydraulics, downstream deluge hydraulics and surge analysis.
Fire Water Piping & Instrumentation Diagrams:Once the fire potential equipment’s fire protection methods are identified and hydraulic calculation are done, the solutions are implemented via P&ID preparation as first step. FW P&IDs shows the piping size, piping material class, pressure rating, instrumentation, number of spray/sprinklers and its distribution etc.
Fire water layout: The piping discipline with FW P&IDs as inputs produce the FW routing layout on plot plan and technical safety will provide input in careful positioning of deluge valves as it is a Safety critical element.
Deliverables: The following deliverables are usually part of Fire protection engineering for a typical Oil and Gas facilities,
