The installation and maintenance of CO2 systems are not merely best practices but stringent legal requirements mandated by the International Maritime Organization (IMO) under the SOLAS Convention. This global mandate, primarily for machinery and cargo pump rooms, is born from decades of maritime tragedy and lessons learned. The regulations enforce rigorous design standards, regular inspections, and crew training drills. Compliance ensures the system is operational at a moment's notice. Adhering to these rules transcends legal obligation; it is a fundamental ethical duty to protect human life, valuable assets, and the marine environment from the devastating consequences of an uncontrolled fire at sea.
