2. Personnel receiving and unpacking samples should be aware of the potential health hazards of the samples and have been trained in the use of routine precautions, especially when dealing with broken or leaking containers.

3. The sample should be opened in the biological safety cabinet, and the disinfectant should be prepared. Operators should wear waterproof protective clothing, biosafety masks, goggles, and gloves.

4. Before opening the package, carefully check the appearance of each container, whether the label is complete, whether the label and inspection report are consistent with the content, whether there is pollution, and whether the container is damaged, etc., to register a detailed report and record the disposal method. .

5. Sample packages should not be received and opened in offices and ordinary BSL-1 laboratories.

Opening of specimen tubes or specimen containers

1. The sample tube should be opened in a Class I or Class II biological safety cabinet.

2. Gloves must be worn. Eye and mucosal protection [goggles or face shield (helmet)] is recommended.

3. Wear a plastic apron over the protective clothing.
