[/!. 1.1. Plastic pipes shall be connected by welding" gluing" cementing" lamination or similar methods in accordance with Sec.1- [0! or by approved detachable connections in accordance with Sec. [/!. 1.1.! nstallation of pipes for water" steam or oil behind or above electric switchboards shall be avoided as far as possible. f this is impracticable" all detachable pipe (oints and valves shall be at a safe distance from the switchboard or well shielded from it. 1.1.& 2ater pipes and air and sounding pipes through free,ing chambers shall be avoided. G'i(ance note) 'or special requirements regarding air" sounding and water pipes penetrating insulated tan% tops" see Pt.3 Ch.0 Sec.1[0.0.4!.
1.1.* Piping systems shall be adequately identified according to their purpose. 5alves shall be permanently and clearly mar%ed.
1. 6peration of valves 1.2.1 2here valves are required by the rules to be readily accessible" their controls shall be located in a space entered without using tools7 and shall be protected from obstructions" moving equipment and hot surfaces that prevent 8hinder9 operation or servicing. 1.2.2 2here remotely operated valves are required by the rules to also be arranged for local manual operation" the changeover to manual operation shall be simple to e&ecute. This implies that there shall be no need to use additional tools for removal of covers or similar to get access to operate the valve manually. 1.2.3 Sea suction and discharge valves located in dry compartments" bilge valves and valves on the fuel oil and lubricating oil tan%s which are situated higher than the double bottom tan%s" shall be arranged for local manual operation. G'i(ance note) 2here hydraulically actuated sea suction and discharge valves are located in the engine room" a hand pump ready for use fitted to each actuator is considered acceptable as local manual operation.
1.2.4 'or remotely operated valves" failure in valve control system shall not cause# $ opening of closed valves $ closing of valves that need to remain open to maintain propulsion and power generation. 1.2. All valves in cargo and ballast tan%s which are hydraulically or pneumatically controlled are also to be arranged for manual operation" e.g. with a hand pump connected to the control system.
1.2.! Spindles of sea suction valves" discharge valves below the load line" emergency bilge valves in engine rooms and blow down discharge valves shall e&tend above the floor plates or by other means be easily accessible and visible. 'or vessels with class notation E+ see also# Pt.4 Ch.1. 1.2.& :emotely controlled valves shall be provided with indications for open and closed valve positions at the control station. n cases where possibility of local manual operation is required in addition to the remote control" means of observing the valve position at the valve location shall be provided.
