According to USCG recommendations, what should all seacocks be fitted with?

Seacocks play a critical role in marine safety by controlling water flow into and out of the vessel, particularly through hull fittings. The United States Coast Guard (USCG) recommends that all seacocks be fitted with specific safety features to ensure optimal operation and prevent accidental openings. Among those are double hose clamps, which are widely recognized for enhancing the reliability of connections and preventing leaks.

A critical function of double hose clamps is their ability to provide an additional layer of security when securing hoses to the seacock. This reduces the risk of a hose coming loose, which could lead to significant safety hazards, including water ingress that may compromise the vessel's integrity. Therefore, the appropriate fitting of double hose clamps is aligned with good marine practice.

While warning labels can be beneficial for alerting users to potential hazards associated with seacocks, they do not provide the mechanical security necessary to prevent failure of the connection itself. Thus, the best practice, in alignment with USCG recommendations, emphasizes securing the physical connections rather than solely relying on informational warnings. This leads to the conclusion that if no recommended safety fitting is provided, choosing "none of the above" accurately reflects a lack of compliance with USCG guidance regarding seacock safety.
