The Hazard Communication Sign is not intended to restrict access or cause alarm, but to communicate that hazardous materials are present in the laboratory which, if improperly utilized, pose a potential risk to your health and safety. Therefore, it is vital that you only use these materials as the safety data sheet or the primary investigator (PI) instruct.

Door Sign (aka Hazard Communication Signs) requirements

As outlined in OSHA's  new 2016 Hazard Communication standard 29 CFR 1910.1200,  All laboratories MUST have a Hazard Communication Sign posted! 

As required by regulation and for the benefit of WCSU personnel, outside contractors, emergency personnel,or other visitors to an area, WCSU posts a Hazard Communication Sign on all laboratory doors and other select room doors where hazardous materials may be present.

The Hazard Communication Sign must display (through symbols, icons and text) which types of hazards(e.g. biological, radiological, or chemical) are potentially present beyond the door. The sign must also list Primary investigator and emergency contact information.

The sign must clearly indicate that anyone who has not been properly trained is not authorized in the area without an escort. Posted rooms should not be entered without an escort from the lab or prior approval from facilities, the chair of the department, or from the primary investigator.
