The Biohazard Warning Sign restricts laboratory access during work with biohazards, communicates the agents in use, and specifies entry or exit requirements. It is the responsibility of the Principal Investigator or supervisor to properly identify and restrict access to the laboratory and to notify emergency and support personnel of any hazards in the laboratory.
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially higher or lower than the ambient pressure. Examples include glassware, autoclaves, compressed gas cylinders, compressors (including refrigeration), vacuum chambers and custom designed laboratory vessels.
The purpose of the personal protective equipment (PPE) program is to protect researchers, employees, students, and visitors from potential hazards in the work environment. However, eliminating hazards through engineering or administrative controls provides better and more consistent protection than relying on PPE alone. If PPE is necessary, it is best used with engineering and/or administrative controls along with good work practices.
The Empty Chemical Containers Focus Sheet provides guidance to dispose of or reuse chemical containers in accordance with hazardous waste regulations.
