Holes or cracks: When gloves have obvious holes or cracks, they must be replaced immediately. Even minor damage can greatly reduce the protective performance of gloves and make them unable to effectively block bacteria, viruses and other harmful substances. For example, when performing medical operations, if a sharp instrument accidentally pierces the gloves, new gloves should be replaced immediately to prevent pathogens from contacting the skin through the damaged area.
Stretching deformation: If the gloves are overstretched, resulting in severe deformation and unable to fit the hands tightly, they also need to be replaced. Deformed gloves not only reduce the protective effect, but also affect the flexibility and accuracy of the operation. For example, when performing delicate manual operations, if the gloves become loose, it may affect the touch and movement accuracy of the hands.
Contact with corrosive substances: When gloves come into contact with corrosive substances such as strong acids, strong alkalis, and organic solvents, they should be replaced in time. These chemicals may quickly destroy the material of the gloves, causing them to lose their protective function, and may also penetrate through the gloves to the skin and cause harm to the human body. For example, when working in a chemical plant, if the gloves come into contact with concentrated sulfuric acid, the gloves should be removed immediately, the hands should be rinsed with water, and then replaced with new gloves.
Color change or odor: If the gloves change color after contact with certain substances, or produce odor, this may mean that the gloves have been contaminated by chemicals and need to be replaced. For example, after contact with certain dyes or chemicals, the gloves may change color, indicating that the material of the gloves has changed and the protective performance may be affected.
Specified use time: In some specific industries and occasions, there are regulations on the use time of disposable latex gloves. For example, in the medical industry, disposable latex gloves are generally recommended to be replaced every 2-4 hours to ensure the protective effect. If the prescribed use time is exceeded, new gloves should be replaced even if the gloves do not appear to be obviously damaged or contaminated.
Feeling uncomfortable: If you feel that the gloves become damp, stuffy, or your hands have uncomfortable symptoms such as itching and allergies during use, you should also replace the gloves. Wet gloves will reduce the protective performance and are prone to breeding bacteria. Allergic reactions may be caused by latex proteins or other additives in the gloves, and they should be replaced immediately with latex-free or hypoallergenic gloves.
