What must be ensured about the storage of hazardous materials onboard?

The storage of hazardous materials onboard a vessel must be in designated areas to ensure safety and compliance with regulations. Designated storage areas are specifically chosen for their ability to contain hazardous materials and prevent accidental leaks or spills. These areas are often equipped with appropriate safety features, such as adequate ventilation, secondary containment, and signage to alert crew members to the presence of dangerous substances.

Storing hazardous materials in non-designated areas could lead to an increased risk of exposure, chemical reactions, or fire hazards, particularly in locations such as crew quarters or the bridge, which are not designed for such purposes. Maintaining strict practices around the storage of hazardous materials is essential for protecting the crew, the vessel, and the marine environment from potential hazards associated with these substances.
