Oil leakages into electrical equipment may be ignited due
to sparks normally generated by operation of switchgear (fine oil
spray is probably most susceptible to ignition). Water leakages may
cause short circuiting and ignition of insulation or other material
of plastic type. The owner and operating personnel should in particular
look for signs of leaking flanges, deterioration of pipes and leakages
from other machinery which may come into contact with subject electrical
equipment.
