SOLAS
noun
Definition of SOLAS
SOLAS stands for the International Convention for the Safety of Life at Sea. It’s the world’s leading maritime safety treaty, setting the minimum safety standards for how ships are built, equipped, and operated.
First adopted in 1914 after the Titanic disaster, SOLAS has been updated several times. The current version, SOLAS 1974, is enforced by the International Maritime Organization (IMO) and ratified by over 160 countries.
The goal of SOLAS is to protect lives at sea by ensuring ships follow strict design and safety requirements, including:
-
Construction and stability standards to prevent capsizing
-
Fire detection and protection systems
-
Life-saving appliances like lifeboats and life rafts
-
Navigation and communication equipment
-
Emergency power and lighting systems for safety during power loss
Under SOLAS, any vessel over 500 gross tons (GT) operating on international voyages must have an independent emergency lighting system that can operate for at least three hours when main power fails.
Example in a Sentence
“The crew tested the emergency lights to ensure compliance with SOLAS requirements before departure.”
