C. DocksidePump-Out
The decomposition of waste produces a color-
less, odorless gas, methane, that is lighter than
air, combustible, and extremely lethal. Always
provide sufficient ventilation when effecting re-
pairs to the waste system and allow no odor
from the waste system to go unresolved.
Waste can be removed from the holding tank by taking
theboattoadocksidewastepumpingstation. Mostmarina
fueling facilities provide such services.
