Some of the most tragic farm accidents are associated with manure pits. Death from toxic gases or drowning can occur. In some cases, multiple deaths have occurred when a second or third person tries to rescue someone else.

Provide forced ventilation before going into any manure storage area
Wear a harness with rescue rope, and have plenty of help available to pull you away If necessary
Never walk on the crust formed on top of manure storage
Have warning signs in appropriate areas near manure storage
