Proper categorization of waste before it reaches thee autoclave reduces the risk of equipment damage, incomplete te decontamination, and regulatory uncompleance.

Modern autoclaves offer multiple cycle type. The gravity displatement cycle is approphable for most solid waste loads, were steam enters the chamber and forces air out through gh a drain.
