14. Floats and the flotation material for all docks and boat mooring buoys
shall be fabricated of materials manufactured for marine use. The float and
its flotation material shall be 100% warranted for a minimum of 8 years
against sinking, becoming waterlogged, cracking, peeling, fragmenting, or
losing beads. All floats shall resist puncture and penetration and shall not
be subject to damage by animals under normal conditions for the area. All
floats and the flotation material used in them shall be fire resistant. Any
float which is within 40 feet of a line carrying fuel shall be 100% impervious
to water and fuel. The use of new or recycled plastic or metal drums or non-
compartmentalized air containers for encasement or floats is prohibited.
Existing floats are authorized until it or its flotation material is no longer
serviceable, at which time it shall be replaced with a float that meets the
conditions listed above. For any floats installed after the effective date of
this specification, repair or replacement shall be required when it or its
flotation material no longer performs its designated function or it fails to
meet the specifications for which it was originally warranted.
