Regular barn maintenance is a key part of risk management. Electrical systems should be checked at least annually, and when replacing parts it is a good idea to use corrosion resistant and surge protected material. An alarm system should be used to monitor for temperature and power failure, and should be tested regularly. Generator and heating system maintenance should be done regularly. All barns should have a rodent program, fire extinguishers, and fire walls. Any welding should be done outside of the barn whenever possible.
