As farmers begin to cut, bail and store the hay in warmer conditions, it is important to know the risks, especially after seven hay sheds caught on fire in Kerang following a recent damaging ember attack.
Kerang captain Ramon Steel said crews arrived at the scene to see just one hay shed engulfed in fire before an unexpected wind change started an uncontrollable firestorm.
“Several hours later, we were hit with an ember attack, and the fire spread to a further six sheds,” he said.
“We had 26 CFA units on scene and were able to utilise the appliances and volunteers available to save the other 13 sheds.”
Such fires are not unusual, with the CFA having responded to over 50 haystack-related fires between July 1, 2022 and June 30, 2023.
CFA chief officer Jason Heffernan said if hay was baled with high moisture content and was green, it could heat up like compost, leading to spontaneous combustion weeks or months later.
“Farmers who have decided to carry on with hay production need to be extra vigilant this year to make sure conditions are right for making hay and for the future storage and transport as well,” he said.
“Whether you’re a seasoned hay grower or switching to hay this year, it’s imperative to take care of your hay and crops this fire season.”
When hay isn’t properly cured or dried out before baling or exposed to rain or damp conditions, moisture content in the bales is higher than the recommended level, leading to fires.
Mr Heffernan said farmers should monitor for signs of heating hay, which could include steam rising or unusual odours such as burning, pipe tobacco, caramel or musty smells.
“You should regularly monitor your haystacks by using a temperature probe or a crowbar to detect heating hay,” he said.
“By being vigilant, you’re protecting yourself from the financial impact of losing valuable fodder and protecting your property and family from the potential danger of hay fires.”
