BS 8627:2019 pdf download.Fire and rescue service equipment – Ultra-high pressure firefighting equipment – Specification
Ultra-high pressure firefighting equipment (UHPFE) has demonstrated value in assisting with the safety of firefighters at operational incidents. Correctly designed, installed and maintained UHPFE can allow the rapid and safe application of water mist from outside a fire compartment in one continuous action. Operation of the system rapidly reduces the temperature inside a fire compartment as well as the rate of production of heat and smoke, allowing firefighters to enter a compartment under more permissible conditions. This British Standard accordingly covers design, maintenance and testing of UHPFE for use by trained and competent personnel. The use of components that have been tested and conform to relevant component specifications for firefighting operations is also important for system performance and reliability. The testing and approval of system components for UHPFE is a developing area and in some instances it might be appropriate to select components that have been approved for use in commercial ultra-high pressure water systems. The provision of UHPFE does not negate the need for other firefighting equipment.
1 Scope
This British Standard specifies requirements for ultra-high pressure firefighting equipment (100 bar to 350 bar), designed to pierce a hole using ultra-high pressure water and abrasive to deliver water mist for firefighting purposes in one continuous action. .
This British Standard is relevant to manufacturers and operators of ultra-high pressure firefighting equipment.
