SOLAS
SOLAS (Safety of Life at Sea) is the most important international treaty governing the safety of merchant ships. First adopted in 1914 in response to the Titanic disaster, it has been revised many times — the current version is SOLAS 1974 with extensive amendments.
SOLAS sets minimum standards across 14 chapters covering: construction (subdivision, stability, machinery), fire protection, life-saving appliances, communications, safety of navigation, carriage of cargoes (including grain and dangerous goods), nuclear ships, safety management (ISM Code, Chapter IX), high-speed craft, special measures, security (ISPS Code, Chapter XI-2), bulk carriers, and polar code.
All ships engaged in international voyages must comply with SOLAS, with certificates issued by the flag state administration or its recognised organisation (typically a classification society).
SOLAS is the floor beneath every safety rule at sea. Born from the Titanic disaster, it is why ships carry the lifeboats, fire systems, radios and certificates they do. It is also the parent of other key codes — ISM and ISPS live inside it as chapters — so falling out of SOLAS compliance can detain a vessel and halt its trade.

What does SOLAS cover?
Minimum safety standards across 14 chapters — ship construction and stability, fire protection, life-saving appliances, radio communications, safe navigation, cargo carriage, safety management (ISM) and security (ISPS).
How do ISM and ISPS relate to SOLAS?
They are chapters within SOLAS — ISM is Chapter IX (safety management) and ISPS is Chapter XI-2 (security). MARPOL, which covers pollution, is a separate convention.
