Examiners should wear protective equipment in the clean area before entering the semi-contaminated area and organize autopsy instruments in the semi-contaminated areas before entering the contaminated area for autopsy. After the autopsy, the protective clothing and gloves require disinfecting first in the contaminated area of the autopsy laboratory, and the protective clothing, mask, shoe covers, gloves, and other equipment surfaces require thoroughly disinfecting in the semi-contaminated area a second time before removing. All must be sent for bio-safety disposal immediately.
