BS 5041-3 discusses components for fire hydrant systems. The aim of the BS 5041 series is to provide best industry requirements for the safe and reliable use of fire hydrant systems, such that they play a positive role during a fire emergency.
BS 5041-3 is the third part of the BS 5041 series of standards that specifies the requirements for 2-way and 4-way inlet breechings intended for dry risers only. They are to be fitted with male instantaneous connections complying with the requirements of BS 336, drain valves complying with the requirements of BS 5154, rating PN 16, and non-return valves.
BS 5041-3 on landing valves for wet risers is useful for:
Fire hydrants are the most commonly used water-based suppression systems for general fire fighting requirements. A fire hydrant, also called a fireplug, fire pump, johnny pump, or simply pump, is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. To prevent hazardous situations, it is necessary that fire hydrant systems and their accessories are designed and built as per best industry performance requirements.
BS 5041-3 provides you with requirements and test methods that can be followed while manufacturing inlet breechings for dry riser inlets. This can enable the fire and rescue service to connect lay flat hose to a suitable water supply, allowing water to be pumped from the fire appliance pump up to higher floors or to where there are extensive distances from an entrance.
If you are a manufacturer, BS 5041-3 can ensure that your inlet breechings for dry riser inlets contribute to the operational efficiency of the gas extinguishing system and contribute to a successful fire response.
