  • The SFU door signage program provides emergency responders with information about the hazardous materials in a room so that they can plan a safe entry response in the event of an emergency. Without this information, they may not risk sending crews into rooms where the hazards are unknown, or they may create unnecessary damage to equipment and research.

How to Generate a Chemical Hazard Sign

An online form prompts users for information regarding the quantity, health, flammability, and reactivity of solid, liquid, and gaseous materials in each room. The form is submitted to an EHRS database where a sign representing a summary of the room hazards is generated.

You will be asked to fill in emergency contact information and the quantity of chemicals in each category (flammability, reactivity and health). This information can be obtained from the Material Safety Data Sheets (MSDS) for each chemical.

Once you have completed and submitted the form, the Environmental Health and Research Safety Department will print out your sign and will place it inside the door plaque on the appropriate door in your department.

The sign should be updated on an annual basis to ensure that it accurately reflects the chemicals present in the room and the appropriate emergency contact information.

Please refer to the list below for additional information about the door signs at SFU.

Chemical Hazard Sign

The chemical hazard sign (or "door hazard sign") indicates the health, flammability, and reactivity hazards, as well as the relative quantity of hazardous materials in a room. Each number is on a scale from 0 (no hazard) to 4 (severe hazard).


Biohazard Sign

This orange and black sign is only for labs requiring level 2 containment for the organisms they are working with.  Level 1 labs do not require a biohazard sign but must still comply with applicable requirements


Radiation Sign

This red and yellow trefoil identifies those areas containing radioisotopes.  Please contact Radiation Safety for more information or signage.


Wet Mopping Sign

For rooms with a biohazard or radioactive sign, wet mopping will only be provided if it has been pre-arranged for a designated night, and if the wet-mop sign is displayed on that night. By displaying the wet-mop sign, you are ensuring the cleaning staff that there are no biohazardous or radioactive contaminants on the floors. On your designated night of each two-week period, the cleaning staff will check your door plaque for the wet-mop sign; if no wet-mop sign is displayed on your designated night, the cleaning staff will skip your lab until the next two week period. 

To obtain a Wet Mopping sign, please contact Melinda Skura at 778-782-7264.


Do Not Enter Sign

This sign is used to restrict access to a lab. It is useful for restricting entrance due to light sensitive reactions. Also, custodians will not enter for any reason. 

To obtain a Do Not Enter sign, please contact Melinda Skura at 778-782-7264.

Magnet Sign

This sign indicates that strong magnets are in use. Do not enter if you have a pacemaker, metallic implant, or neurostimulator. Iron, steel and other ferrous materials, such as keys and scissors, should not be brought into this room.

Laser Sign

This sign indicates that lasers are in use. Skin and eye exposure to direct or scattered radiation should be avoided. For more information please see Radiation Safety's laser webpage
