The Centers for Disease Control (CDC) recommends that schools prepare or adapt a biosafety manual, and that instructors develop a list of safety procedures applicable to their own lab and distribute it to each student. In this way, safety issues will be brought to each student's attention. This document is an example of such a manual. It contains guidelines adapted from CDC guidelines for use in a school setting. Topics covered include: aerosols; chemical safety; decontamination; disinfection; waste disposal; teaching precautions; standard and special practices; universal precautions; and precautions for blood work.
