Card Instructions

Place the animal in a clean cage after it recovers from surgery.

DCM will not change the cage or directly handle any animals that have been exposed to hazardous materials while the red card is on the cage. They will add food or water as necessary. The experimenter is responsible for changing the cage until the card is removed 3 days after the last administration of the hazardous compound.

Once the red card is removed, change the cage and place soiled cage into an autoclave or biohazard bag. Ask your animal facility staff where they want the cage left for disinfection.
