Does hay have spontaneous combustion?
If the hay crop is put into the mow above 20-25% moisture content, spontaneous combustion may occur. A hay crop that is placed too wet into a mow will heat rapidly. If the mow is so large that heat loss is restricted, the internal temperature will rise.
What can cause spontaneous human combustion?
Proposed causes of the supposed phenomenon include bacteria, static electricity, obesity, stress and—most consistently—excessive consumption of alcohol, but none have been substantiated by science so far.
Can straw self combust?
Breadcrumb Menu. Usually, we think of water and moisture as a way to put a fire out, but the opposite is true with hay and straw, which when too wet can heat and spontaneously combust.
Can old hay self combust?
Actually, wet hay is more likely to lead to spontaneous combustion than dry hay. If wet hay with more than 22% moisture is stored in a barn or stacked then the risk of spontaneous combustion is increased.
How long does it take hay to combust?
“Depending on forage moisture at baling and how hay is stored, excessive heating and molding can occur,” Bushong said. “The time required from heating to combustion can vary from a few days to 10 weeks, depending on conditions.”
When was the last spontaneous human combustion?
December 2010
In December 2010, the death of Michael Faherty, a 76-year-old man in County Galway, Ireland, was recorded as “spontaneous combustion” by the coroner.
How common is spontaneous human combustion?
The eyewitness accounts of the tragic incident have re-launched the debate surrounding spontaneous human combustions (SHC). The apparent occurrence has never been proven, but has been linked to around 200 incidents.
Why does straw spontaneously combust?
Moisture content is the main factor that causes hay and straw to spontaneously combust. Hay fires are more common than straw fires, for reasons involving the type of forage, the moisture content in the stored forage, and heat production.
How long does it take for hay to combust?
How do you stop hay from burning?
The best way to prevent fires is curing hay to the proper moisture level before storing it because storing hay with higher moisture results in more heating. Weather conditions during curing have the greatest influence on achieving the proper moisture concentration.
How rare is spontaneous human combustion?
When was the last case of spontaneous human combustion?
The most recent death linked to SHC was that of Michael Faherty, 76, who died at his home in Galway, Ireland in December 2010. Dr Ciaran McLoughlin, the coroner tasked with explaining Mr Faherty’s sudden death at his home in Ballybane, made the shock decision of putting it down to SHC.
Is burning hay toxic?
Toxic gas exposure: Smoldering and burning hay can be the source of toxic gases. Carbon monoxide can be concentrated within the smoldering fire and surrounding area. Chemically preserved hay crops may produce toxic gas vapors.
Can moldy hay cause fire?
Temperatures should be taken from the center of the stack or “down about 8 feet in large stacks.” Not only can wet hay catch fire, but it can mold. Hartschuh says bale temperatures of 120° to 130° F often results in mold growth and makes the protein less available to animals.
