The cause of a barn fire is often unknown, which makes preventing fires in other barns difficult. However, there are preventative measures that all barns should have in place, like working fire extinguishers and spec-grade electrical receptors. Maintenance is also very important and structure, the attic, plumbing, electrical, and heating systems should be inspected at least yearly. Other maintenance ideas are having a hot work permit before welding or cutting inside the barn, and fire separation walls in the attic. Exposed polyeurethane insulation is a fire risk, and should be covered up or coated with fire retardant. One of the reoccurring causes that can be determined is the buildup of methane gas, especially in closed up barns with manure pits. Speaking to a risk management staff at your insurance company will help to identify any additional risk areas in your barn.
