Arrangements for evacuation, including routes and host sites, should be made in advance. Alternate routes should be mapped out in case the planned route is inaccessible.
The evacuation sites should have or be able to readily obtain food, water, veterinary care, handling equipment and facilities.
Trucks, trailers, and other vehicles suitable for transporting livestock should be available along with experienced handlers and drivers to transport them. Whenever possible, the animals should be accustomed to these vehicles in advance so they're less frightened and easier to move.
If evacuation is not possible, a decision must be made whether to move large animals to available shelter or turn them outside. This decision should be determined based on the type of disaster and the soundness and location of the shelter.
All animals should have some form of identification that will help facilitate their return.
