High-efficiency Xa substrate can be used for laboratory scientific research and industrial quality control, but it must not be used as a drug. Personal protective measures should be observed when using high-efficiency Xa substrate:

1. Eye protection

Safety glasses with protective side shields.

2. Skin protection

Gloves should be worn when handling; gloves must be inspected before use, and appropriate methods should be employed to remove gloves after use (do not touch the outer surface of the gloves) to avoid contact with any skin areas. Contaminated gloves should be disposed of cautiously according to relevant procedures.

3. Body protection

A complete set of chemical-resistant work clothing; the type of protective equipment must be selected based on the concentration and content of hazardous substances in the specific workplace.

4. Respiratory protection

An air-purifying respirator should be used if risk assessment indicates the need.
