1. Appearance inspection
Damage: Carefully observe whether the gloves have cracks, perforations or scratches. Even a small damage may cause the gloves to lose their protective function and need to be replaced in time. For example, when performing medical operations or laboratory work, if the gloves are damaged, it may cause the invasion of germs, chemicals, etc., causing harm to the user.
Discoloration: If the color of latex gloves changes significantly, such as yellowing or darkening, it may be a sign of aging or contamination of the gloves. Aged gloves may become fragile and easy to break, and contaminated gloves may affect the safety of operation, and both need to be replaced.
Deformation: When gloves are severely deformed, such as twisting, excessive stretching and unable to return to their original shape, it means that the elasticity of the gloves has been damaged and cannot be used normally. New gloves should be replaced.
2. Touch inspection
Sticky: If latex gloves become sticky, it means that the gloves may have aged or been affected by chemicals. Sticky gloves are not only uncomfortable to use, but may also affect the accuracy and safety of operations and need to be replaced.
Hardening: When gloves harden, their flexibility and protective performance will be reduced. This may be caused by the gloves being exposed to a bad environment for a long time or being used for too long, and should be replaced in time.
3. Use time
Reference to the instructions for use: Different types of latex gloves may have different recommended use times. For example, some disposable latex gloves may be recommended to be replaced after one use, while some durable latex gloves may be used multiple times, but they also have a certain use period. You can refer to the product's instructions for use to determine whether the gloves need to be replaced.
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.
Allergic reactions: If the user experiences allergic reactions such as skin itching, redness, swelling, and rash after wearing latex gloves, the gloves should be stopped immediately and replaced with gloves of other materials. At the same time, you should seek medical attention and receive allergy treatment in time.
