Haystack fires have a range of causes such as lightning strikes, sparks from equipment and machinery and deliberately or accidentally started. However, many haystack fires self-ignite for no apparent reason. This is called spontaneous combustion and is the leading cause of haystack fires in Australia.
Haystack fires can spread quickly into the surrounding area and often result in thousands of dollars of damages. WFI provides some useful tips to reduce the risk of haystack fire.
POINTS TO REMEMBER
Before cutting and storing hay, consider the following points:
1. The node should be fully booted (emerged) from stem sheath prior to cutting. Depending on the variety (slow or fast maturing varieties) the node may sometimes not be fully emerged, in which case the curing time must be longer to ensure no moisture is present within the nodes.
2. Moisture is stored in the node within the stem of the plant. If the stem is not crimped/cracked (by using a mower conditioner or a super conditioner) the moisture will not escape as quickly and curing times will need to be longer.
3. Curing process is the key element to stopping spontaneous combustion fires. Curing times depend upon:
4. An effective curing test available to farmers is to use the “hammer test” i.e.; squashing the node between two metal surfaces and looking for any moisture from the crushed node. If ANY moisture appears, this hay is not ready for baling.
5. Moisture: After hay is cured (and no moisture is present in “hammer test”), hay bales should not be baled with moisture contents greater than 15% (for cereal hay – oats or wheaten hay, etc.). If hay is not cured to the point at which no moisture is present at “hammer test” stage, the moisture reading will not be a true reflection of the moisture content.
6. If the hay has a slight caramel odour/ strong musty smell/strong burning odour or visual vapours, you should investigate the source of the odours and take appropriate actions. These are strong indicators that a spontaneous combustion fire may occur.
REDUCE THE FIRE RISK
Even if you take all the possible precautions to prevent haystack fires, losses can still occur, therefore, you should ensure you have the adequate level of insurance protection just in case the unthinkable happens. It is a good time to check your insurance policies to ensure your hay, hay sheds and machinery are adequately covered. If you would like to review your insurance policies or you would like further information about other practical measures you can put in place to reduce the risk of haystack or shed fires contact your WFI local area manager on 1300 934 934.
