Risks of fire must also be considered when choosing materials. There are certain building regulations that apply to all public buildings: Fire extinguishers must be installed and inspected regularly; wiring must be inspected, etc. Other aspects of construction and layout are left to common sense. The kennel owner can work with the local fire department to determine what fire safety measures should be taken, such as where to place water sources.During construction of the kennel, the breeder and architect should select fire-resistant building materials and pay careful attention to their characteristics. They should consider whether the material is non-flammable, combustible and stable when heated by fire, and whether it is designed as a flame shield or firebreak. Polyurethane foam, for example, is non-flammable, but combustible.
