What are veterinary crash carts made from?

A "crash cart" can consist of many different things, but primarily they are plastic. They are not a particular item, but rather a collection of materials and drugs commonly used in an emergency situation and stored in a box (often a tool box or organizer box) so that they can be easily moved to where they are needed in a veterinary facility. Each practice typically puts together it's own "crash cart" or "crash box" based upon their particular needs.
