Signs and Labeling


All laboratories including tissue culture rooms, cold rooms, and common equipment rooms must register for a door sign, which will be posted on the outside of the laboratory door, facing the hallway.  This door sign will indicate what types of hazards are found in the lab and will also have PI and emergency contact information. 

To request a laboratory door sign:

  1. Use your UMID to login to MyEHS
  2. Click on “Door Sign Request”
  3. Read instructions, fill out relevant information, and click“Submit” when finished

Once a request has been submitted, the door signs will be delivered to you within 3 days.  If you have multiple rooms, you will need to submit multiple requests. If you would like to pick up your door sign or have any questions about requesting a door sign please contact EHS at (410) 706 -7055.


All equipment and materials used to store or transport of potentially infectious material must be labeled with the universal "Biohazard" symbol. The label must be orange or red-orange with the biohazard symbol in a contrasting color.  A Biohazards sign needs to contain the symbol as well as the word “Biohazard”.  EHS does not provide Biohazard Stickers. However, several vendors provide pre-printed stickers for this purpose.
