Cage labels and door signs: what you need to know

Cage labels and door signs: what you need to know

Attention, animal researchers!

Properly completing cage labels and door signs is not just a mundane task; it is a crucial part to keeping your fellow researchers, veterinary staff, animal husbandry staff, and visitors safe from exposure.

Cage labels

Each hazard has its own cage label:

  • Biological agents require the biological hazard label.
  • Chemical hazards need the health hazard label.
  • Radioactive hazards use the radiological hazard label.

When labeling do not forget the essentials: the substance name and disposal method. Add an end date, if applicable.

Door signs

If a hazardous substance is in use, make sure the corresponding door sign is posted on the animal room door. When the hazard is no longer present, cross out the cage label and flip the door sign to communicate that the room is safe.

The EH&S Animal Research Safety Team will be stopping by for a spot checks. If we find anything amiss, we will give the PI guidance on how to correct the issue.

Stay safe, and happy labeling!
