Laboratory entrance signs are required by regulatory agencies and are essential to safety by providing critical information to lab users, visitors, and emergency responders, alerting them to specific hazards in the respective lab. Lab entrance signs are to be posted at all entrance(s) to each functionally separate laboratory. In an open space lab design (such as seen in Genetics Medicine Research Building), each bench will have signs posted to specify the Principal Investigator and specific hazards located on that bench.

This new signage program allows the (Principal Investigator and/or lab personnel) to create a customized sign specifically for their lab by choosing the appropriate hazard pictogram. The information on each sign must also include names and emergency phone numbers of the principal investigator and any other designated personnel (i.e. safety supervisor and/or building manager) so that first responders and/or other safety personnel have the critical contact information readily available to them in the event of an emergency.

Lab entrance signs are created via the web application below. After you select the pictograms and input the information for your sign, EHS will print it and post it at the entrance(s) to your lab. An editable PDF of the sign will also be accessible on the “Room Use” page of the online lab safety plan in case you need to update contact information. See an example of the laboratory entrance signs.

Training and assistance in using the Lab Entrance Sign program are available through EHS. If you have any questions about the program please contact the Chemical Safety section (
