like pigs in shit http://www.foxnews.com/health/2015/...ives-to-manure-pit-deadly-gases/?intcmp=hpbt4 An Iowa father and son are dead after tangling with a deadly aspect of hog farming: their manure pit. Typically situated below a barn, the manure's noxious fumes don't escape easily, and the hydrogen sulfide— along with methane, ammonia, and carbon dioxide— can be a deadly mix. and not to be outdone: Two Wisconsin men have died after falling into a manure pit and being overcome by the gases. The Chippewa County Sheriff's Office says it happened around 5 p.m. Thursday in the Town of Woodmohr. According to the sheriff's office, Jeremy Seibel and Rodney Seibel of Bloomer were trying to retrieve a piece of equipment that fell into the manure pit. They were overcome by the gas and became unresponsive.
