Hay covers do not provide significant protection against fire hazards. While they can shield hay from environmental factors like moisture and UV rays, they are not designed to prevent or reduce fire risks. In fact, some cover materials are themselves flammable
Surprisingly, wet hay is more flammable than dry hay, since excessive moisture can create heat as the hay ferments, which makes it more likely to spontaneously combust. To mitigate fire hazards, hay should be stored away from potential sources of ignition and proper fire safety measures should in place, such as maintaining clear spaces around hay storage areas and implementing firebreaks. Barns used to store hay should be weather-tight, without any leaks in the roof.
