Maritime safety is the collection of measures to protect life and property at sea. Specifically, the guidelines come from the International Convention for the Safety of Life at Sea (SOLAS). SOLAS provisions range from setting the frequency of ship inspections to implementing approved life-saving appliances. Crew member training and certifications also ensure that sailors follow best practices and protocols at sea. IMO generally oversees international shipping safety matters, but the organization is also responsible for preventing marine and atmospheric pollution.
