In recent weeks, the prevalence of spring flu and other infectious diseases has led to increased demand for disinfection and protective equipment. According to a recent spot check by the Guangzhou Municipal Bureau of Quality Supervision, 3 types of virus protection products—tableware disinfection cabinets, rubber gloves, and industrial disinfectants—were all found to be 100% qualified. However, the bureau has issued a reminder that Guangdong is currently experiencing a high incidence of flu, and proper usage of protective items is essential.
One common issue with rubber gloves is perforation or water leakage, which can compromise their effectiveness. Users are advised to replace new gloves immediately if any damage is detected, to prevent the spread of germs and maintain hygiene.
**Disinfectants: Beware of Drug Resistance**
Disinfectants come in two main categories: industrial and household. When purchasing disinfectants for home use, it's important to check the packaging for key details such as active ingredients, manufacturer information, and product standards. It’s also recommended to choose products from reputable manufacturers and with recent production dates.
Proper use of disinfectants is crucial. They should be used strictly according to instructions, as overuse can be harmful. For example, peracetic acid is a strong oxidizer that can irritate skin and mucous membranes at high concentrations. Chlorine- or bromine-based disinfectants are effective but may cause discoloration of fabrics and corrosion on metal surfaces. After disinfecting food items like fruits or vegetables, they should be rinsed thoroughly with clean water.
Long-term and excessive use of disinfectants can lead to microbial resistance, reducing their effectiveness. To avoid this, it's advisable to alternate between different types of disinfectants.
When storing disinfectant products, keep them in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and incompatible substances such as acids or organic materials. Sodium hypochlorite (type A) and calcium hypochlorite (boiling powder) should be stored separately to prevent dangerous reactions. Also, chlorine-based disinfectants have a limited shelf life, and their effectiveness decreases over time, so they should not be kept for too long.
**Sterilizers: UV Alone Isn't Enough**
Tableware disinfection cabinets come in various types, including built-in, tabletop, and wall-mounted models, as well as those that combine ozone and UV sterilization. Experts warn that ultraviolet radiation has limitations, as it only works where it shines and cannot reach areas in shadow. Therefore, relying solely on UV sterilization may not meet full disinfection requirements.
When purchasing sterilizers, it's best to choose trusted brands and avoid overly cheap options. Always buy from authorized retailers and verify that the product has a valid inspection certificate from the technical supervision department to ensure its safety and performance.
**Rubber Gloves: Replace When Damaged**
There are two main types of rubber gloves: one for industrial and household use, such as acid-resistant gloves or labor protection gloves, and another for medical purposes, like medical gloves or disposable examination gloves. It's important to select the right type based on the intended use.
During use, if any holes or leaks are detected, the gloves should be replaced immediately. This helps prevent contamination and ensures continued protection against pathogens.
