Do not use the centrifuge on an uneven or slanted work surface. If a spill has occurred in the centrifuge, hold breath, close the centrifuge lid, turn centrifuge off, and immediately leave the lab. Notify others to evacuate the lab, close the door, post a biohazard spill sign at the lab door. Remove any contaminated protective clothing and place in a biohazard bag. Wash hands and any exposed skin surfaces with soap and water. Seek medical attention as necessary.
