2.4 Hot surfaces

  .1 All surfaces of machinery with high temperatures above 220°C e.g. steam, thermal oil and exhaust gas lines, silencers, exhaust gas boilers, turbo blowers, etc., shall be effectively insulated with non-combustible material to prevent the ignition of combustible materials coming into contact with them. Where the insulation used for this purpose is oil absorbent or may permit the penetration of oil, the insulation shall be encased in steel sheathing or equivalent material.

  .2 Boilers shall be suitably insulated with non-combustible material and sheathed with steel or other non-combustive material. The clearance spaces between the boilers and tops of the double bottom tanks, and between the boilers and the sides of the storage tanks in which oil fuel and cargo oil is carried, shall be adequate for the free circulation of the air necessary to keep the temperature of the stored oil sufficiently below its flash point, except in the case of tanks complying with Section 2.3.2.

  .3 The insulation shall be of a type and so supported that it will not crack or deteriorate when subject to vibration.
