1 The Maritime Safety Committee, at its sixty-first
session (7 to 11 December 1992), recognized that chronic exposure
to very low concentrations of benzene vapours in air, of the order
of a few parts per million, may cause leukaemia.
2 The Committee, at its sixty-sixth session (28
May to 6 June 1996), desiring to protect the health of seafarers and
to keep it at a level similar to that of shore-based workers engaged

by means of which it:
3 The Committee, at its seventy-seventh session
(28 May to 6 June 2003), noting that the diseases caused by the aforementioned
exposure were still a source of great concern, agreed that MSC/Circ.752 was in need of revision, in
particular with respect to cargo operations, which pose the largest
risk of crew exposure to vapours from the products carried, and approved
Revised minimum safety standards for ships carrying liquids in bulk
containing benzene, as set out in the Annex, which also includes an
example of precautions to be given to the crew in connection with
loading and gas freeing operations.
4 Member Governments are invited to apply the
annexed Revised minimum safety standards for ships carrying liquids
in bulk containing benzene, including precautions to be given to the
crew in connection with loading and gas-freeing operations appended
thereto as soon as possible.
