What actcode or regulation requires that safety equipment be carried on board at all times?

The requirement for safety equipment to be carried on board at all times is typically governed by specific maritime regulations, such as the International Convention for the Safety of Life at Sea (SOLAS) and the Code of Federal Regulations (CFR) in the United States, particularly 46 CFR Part 25 for certain vessels. These regulations outline the necessary safety equipment, such as life jackets, fire extinguishers, and flares, to ensure the safety of crew and passengers. Compliance with these regulations is critical for maritime safety and liability.
