In recent times, the prevalence of spring flu and other infectious diseases has led to increased demand for disinfection and protective equipment. Yesterday, the Guangzhou Municipal Bureau of Quality Supervision released the results of random inspections on three types of virus protection products, including tableware disinfection cabinets, rubber gloves, and industrial disinfectants. All items tested were found to be 100% qualified.
The Municipal Quality Supervision Bureau reminded the public that Guangdong is currently experiencing a high incidence of flu. When using rubber gloves, issues such as holes and water leakage may occur. It is recommended to replace new gloves immediately if such problems are detected to prevent the spread of germs.
**Disinfectants: Beware of Drug Resistance**
According to reports, disinfectants can be categorized into industrial and household types. Experts from the quality supervision department advise checking the main active ingredients, manufacturer's name, address, and product standard number on the packaging when purchasing household disinfectants. It is best to choose recently produced products from well-known manufacturers.
When using disinfectants, it is essential to follow the instructions carefully. Since these products are inherently hazardous, overuse should be avoided. For example, peracetic acid, a strong oxidizing agent, can irritate and damage skin and mucous membranes at high concentrations. Chlorine (or bromine) disinfectants are highly effective but may cause bleaching of fabrics and corrosion of metals. After disinfecting fruits, vegetables, or food and beverages, they should be rinsed with clean water. Long-term and excessive use of disinfectants can lead to microbial resistance, reducing their effectiveness. To prevent this, it is advisable to alternate between different types of disinfectants.
Disinfectant products often have oxidizing and corrosive properties, so proper storage is crucial. Containers containing sodium hypochlorite (Type A) and calcium hypochlorite (boiling powder) should be stored in dry, cool, and well-ventilated areas, away from direct sunlight, fire, and heat sources. They should not be stored together with acids, organic materials, or reducing agents due to potential dangerous reactions. Chlorine-based disinfectants also have a limited shelf life, and their effectiveness decreases over time, so long-term storage is not recommended.
**Sterilizers: UV Alone Isn’t Enough**
Tableware disinfection cabinets come in various types, such as built-in, tabletop, and wall-mounted models, as well as ozone and UV combination sterilizers. Experts note that ultraviolet radiation has blind spots and only works where it directly shines, leaving the backside unaffected. Therefore, relying solely on UV sterilization may not meet full disinfection requirements.
Experts recommend purchasing sterilizers from trusted brands and avoiding overly cheap options. It is best to buy from reputable stores and check the technical supervision department’s inspection certificate to ensure the product’s performance and safety.
**Rubber Gloves: Replace When Perforated**
Quality supervision experts identified two main types of rubber gloves: one for industrial and household use, such as acid and alkali-resistant gloves, labor protection gloves, and general household gloves; and another for medical purposes, like medical gloves and disposable examination gloves. When purchasing, it is important to select gloves suitable for the intended use. If any holes or leaks are detected during use, the gloves should be replaced immediately to prevent the spread of germs.
