6.1 Carriage of products having a flashpoint exceeding 60C (closed cup test) as determined by an approved flashpoint apparatus.

  6.1.1 Regulation 55(a)(i) of Part E, chapter II-2, 1974 SOLAS Conventionfootnote as amended by the 1978 Protocol implies, inter alia, that regulations 60 and 62 do not apply to tankers carrying petroleum products having a flashpoint exceeding 60C; in other words, product carriers may carry bitumens, lubricating oils, heavy fuel oils, high flashpoint jet fuels and some diesel fuels, gas oils and special boiling point liquids without inert gas systems having to be fitted, or, if fitted, without tanks containing such cargoes having to be kept in the inert condition.

  6.1.2 If cargoes with a flashpoint exceeding 60C, whether heated or otherwise, are carried at temperatures near to or above their flashpoint (some bitumen cutbacks and fuel oils), a flammable atmosphere can occur (regulation 62.1 refers). When cargoes with a flashpoint exceeding 60C are carried at a temperature higher than 5C below their flashpoint they should be carried in an inerted condition.

  6.1.3 When a non-volatile cargo is carried in a tank that has not been previously gas-freed, then that tank shall be maintained in an inert condition.
