» What is a Pressure System?
A Calor Gas LPG installation is a “Pressure System” when it is:
a) A bulk storage vessel (tank) and associated pipe work.
b) The pipe work (and hoses) to which a cylinder (bottle) is connected and the pressure is more than 0.5 bar gauge (about 7.5 PSI).
This occurs wherever the LPG is in the liquid state and, in vapour off take installations generally up to the 2nd stage regulator, if fitted. These two types of installation, showing the extent of the “Pressure
System”, are shown in diagram fig 1 and 2 (overleaf). These diagrams are not meant to represent the physical layout of the actual installation nor suggest that all the items shown are present or that other equipment is not present.
The PSSR do not apply to the fuel systems of LPG propelled road vehicles but do apply to their refuelling stations, fixed FLT fuel tanks and vessels in road maintenance vehicles.
Not every installation is the same and if you have any doubts please contact either your regional Customer Operations Centre or the Calor
Technical Helpdesk (0845 602 1143).
