Carriage

As a fine spray of fresh water or surfactant is added during loading, bilges shall be sounded and pumped out as necessary throughout the voyage.

Discharge

Appropriate safety precautions shall be taken when entering the cargo spaces, particularly in the area of the bottom layers of sulphur in ships hold, taking into account the recommendations developed by the Organization.footnote

Appropriate precautions shall be taken to minimize impact, abrasion and crushing when handling to prevent dust from forming.

Clean-up
