This mixture is to remain in the tank until it is cleaned at sea (salt water ok) as per Marpol Regulations. Alternatively this fresh water/acid mixture may be transferred into another clean SS tank or empty (rinsed) acid tank so the tank may be cleaned in port.
Under no circumstances is the fresh water/acid mixture to be mixed with any other slops onboard (except for other Acrylic Acid slops.) After initial rinsing and transfer of slops the Acrylic Acid tank may be cleaned in port with salt or channel water collecting slops onboard along with any other compatible slops.
This cargo can polymerize violently if contaminated or if exposed to freezing (12-14C) or excessive heat (45C) so utmost care needs to be taken when handling or cleaning from this cargo.
