(i) These should be enclosed in a separate fire-resisting service duct as described in 4.4.3.

(ii) The temperature of the pipes shall be kept below critical temperatures for the fluid.

(iii) Where it is not practical to provide protection against leakage, the provision of automatic shut-off valves close to the compartment wall is advisable to assist the control of any leakage.

(iv) Such pipes should not be routed in concealed spaces over rooms containing critical business.

(v) Flammable gases should not be routed below floors unless suitable leakage detection and ventilation is provided.

(vi) Electrical cables and equipment should not be sited in the same under floor void as pipes containing flammable fluids.
