Potable hoses can be made of which material?

• A. Can be made of copper
• B. Must be made of stainless steel
• C. Can be made of glass
• D. Must be made from ceramic

Answer: (A)

Potable hoses must be made from materials that are safe for drinking water and won’t contaminate it. Copper fits this requirement well because it is non-toxic to potable water, resists corrosion in typical water conditions, and is easy to sanitize. That makes it a permissible material for hoses used to carry drinking water aboard vessels. Glass and ceramic hoses would be impractical due to fragility and weight, so they aren’t suitable choices for hoses. Saying the hose must be stainless steel is too restrictive—other approved materials, like copper, can be used as well.
