Preventing Deaths of Farm Workers in Manure Pits
NIOSH Update:

July 3, 2007
The tragic deaths of four members of a Virginia farm family and a farm employee on July 2, 2007, highlight the importance of vigilance when entering manure pits or tanks. Accumulations of methane, hydrogen sulfide, carbon dioxide, and ammonia can pose a life-threatening risk of suffocation and other dangers. The immediacy and magnitude of the hazard may not be readily apparent.
To prevent death or serious injury, NIOSH recommends:
- never enter a manure pit unless absolutely necessary, and only when proper safeguards have been taken
- the atmosphere within the pit should be tested before entry,
- if the atmosphere is toxic or oxygen-deficient, do not enter without proper respiratory protection
- a standby person should be in constant contact and ready to lift the worker to safety with mechanical lifting equipment (winch, hoist, or pulley), and
- anyone entering a manure pit should wear a safety belt or harness with a lifeline tied to the mechanical lifting device
- never enter a manure pit to attempt a rescue without proper respiratory protection
