A maintenance and monitoring programme should focus on a
special set of work practices. The nature and extent of any special
work practices should be tailored to the likelihood that the asbestos-containing
material will be disturbed and that fibres will be released. In general,
four broad categories of work practices are recognised:
-
.1 protection programmes to ensure crew members
are adequately protected from asbestos exposure during normal maintenance;
-
.2 basic operations and maintenance procedures
to minimise and/or contain asbestos fibres;
-
.3 special operations and maintenance cleaning
techniques to clean up asbestos fibres on a routine basis; and
-
.4 procedures for use during incidents of asbestos
fibre release episodes to minimise the spread throughout the ship.
In the latter case, the procedures to be followed will vary
according to the site of the major release episode, the amount of
asbestos-containing material affected, the extent of fibre release
from the asbestos-containing material, the relationship of the asbestos-containing
material to the air handling systems, and whether the release site
is accessible to passengers and crew.
