1. Appearance inspection

2. Touch inspection

3. Use time

Judge according to actual conditions: If the gloves are frequently exposed to harmful substances during use, have experienced high-intensity use or long-term use, even if there are no obvious signs of damage or aging, you should consider replacing the gloves to ensure the protective effect.

4. Special circumstances

After contact with specific substances: If latex gloves are exposed to certain special chemicals, biological contaminants, or high-temperature objects, even if the gloves look fine, they may have been damaged and need to be replaced. For example, after contact with highly corrosive chemicals, the protective performance of the gloves may be greatly reduced.
