2.5 Oil spillages coming into contact with hot surfaces, electrical installations or other sources of ignition

  .1 Precautions (e.g. shielding) shall be taken to prevent oil that may escape under pressure from any pump, filter or heater or piping from coming into contact with sources of ignition.

  .2 Oil tanks, pipes, filters, heaters etc. shall not be located immediately above or near units of high temperature including boilers, steam pipe lines, exhaust manifolds, silencers or other equipment required to be insulated, and electrical equipment and, as far as practicable, are to be arranged far apart therefrom. In particular, fuel oil filters under pressure for diesel engines shall be located such that in the event of leakage oil cannot be sprayed onto the exhaust manifold.

  .3 Oil filters fitted in parallel for the purpose of enabling cleaning without disrupting oil supply to engines (e.g. duplex filters) are to be provided with arrangements that will minimize the possibility of a filter under pressure being opened by mistake. Filters/filter chambers shall be provided with suitable means for:

  • venting when put in operation
  • depressurizing before being opened.

Valves or cocks with drain pipes led to a safe location shall be used for this purpose.

  .4 Hydraulic units with working pressure above 15 bar shall preferably be placed in separate spaces. If it is impracticable to locate such units in a separate space, adequate shielding shall be provided.
