Laboratory Hazard Notice

A Laboratory Hazard Notice is required to be posted by the entrance of your laboratory.  The purpose of this notice is to inform all personnel and authorized visitors of all hazardous materials or situation that they may encounter upon entering your laboratory. The hazard notice must include all chemical, biological, radioactive, equipment and other hazards present in the lab. Emergency contact information and entry requirements must also be listed. 

Should an incident occur in your lab, Emergency responders will rely on the hazard notice to make timely and effective decisions to enter and stabilize the incident area. If you are the designated group Safety officer for your laboratory, you must ensure that the information listed on the hazard notice is accurate at all times.

This hazard notice template [docx] can be modified to create your lab specific signage. The following instructions describe the information required for each section of the notice:

Laboratory Identification - the laboratory name refers to how you refer to your research group; indicate the Building and room number and the name of your Principal investigator.

Entry Requirements and precautions - include statements and phrases that will inform all personnel of the requirements that need to be met before they can enter your laboratory. 

Emergency Contact - Emergency contact should include the Principal Investigator and two lab personnel who are capable of answering questions about laboratory operations. List phone numbers that can be reached outside of normal office hours such as a home phone or a cell phone.

Non-emergency Contact - Personnel and/or offices who can provide information and/or assistance in non-emergency situations.

Chemical Hazards - Review your chemical inventory and safety data sheets to identify the GHS hazard classes of chemicals present in your lab.  List all hazards classes that have Category 1 or 2 ratings.  Remove the pictograms that do not represent hazard classes listed.  List specific substances that are particularly dangerous, i.e., HF, arsine, large volume of highly flammable liquids or gases.

Biological Hazards and Biosafety Level - List all biological materials (derived from living organism) present and the biosafety level assigned to your lab.  Please note that all BSL-2 labs have a specific signage required.

Radiation Hazards - List all isotopes, laser (and class) and x-rays present in the lab.

Physical Hazards - This refers to equipment, instruments, and other items that pose physical harm such as cutting, pinching, crushing, burning, electrocution, high pressure, and others.
