6.1 Abatement actions should be selected and implemented
when necessary. In some instances, due to the condition of asbestos-containing
materials or upcoming ship repairs or modifications, a Company may
decide to take other abatement actions to deal with asbestos-containing
materials in the ship. These response actions could include: encapsulation
(covering the asbestos-containing materials with a sealant to prevent
fibre release), enclosure (placing an air-tight barrier around the
asbestos-containing materials), encasement (covering the asbestos-containing
materials with a hard-setting sealing material) or repair or removal
of the asbestos-containing materials. Qualified, trained and experienced
contractors should be used for any of these actions. The Company should
be aware of any national and local regulations that pertain to abatement
actions to deal with asbestos-containing materials.
6.2 In the event of works requiring the removal
of asbestos-containing materials, they should be unloaded from the
ship. On completion of the work, and before any restoration of the
spaces, the Company should carry out dust measurement after dismantling
the enclosing mechanism. If the work does not result in the total
removal of the materials and products listed in this order, the Company
should carry out regular surveillance of the asbestos-containing materials
at intervals identified by the Company as being appropriate, but not
exceeding 3 years.
