relate to safety valves and pressure gauges, any set of air receivers supplied with air
through a single pipe may be treated as one air receiver:





Provided that, where, by virtue of the said subregulation (1), the air
receiver is required to be fitted with a reducing valve or other appliance to
prevent the maximum permissible working pressure of the air receiver being
exceeded, this subregulation shall not apply unless such valve or other appliance
is fitted on the said single pipe.
