How Gloves are Made ?

图片
Whichever material rubber gloves are made of, they are manufactured in the same basic way. The process starts with hand-shaped ceramic or aluminum molds on a conveyor, which are dipped in wash tanks with hot water and chlorine or bleach and then dried. This dipping gets rid of any potential residue from the previous batch of gloves. Once the molds are cleaned, they must be coated to make the rubber stick. To accomplish this the molds are dipped into a mixture of calcium nitrate solution (which will coagulate the rubber) and calcium carbonate (which is a lubricant to keep the gloves from sticking to the mold too much). A second drying occurs, and then the glove forms dip into tanks of either latex, nitrile, or polyvinyl chloride. This is when the processes begin to differ since the materials must be processed differently. Latex gloves  have their thickness determined by how long they remain in the tank. Once the forms are out, they spin to remove excess rubber and then are washed in hot

Gloves To Wear or Not To Wear?

Why Wearing Gloves is Important It is important to wear gloves when working with hazardous chemicals and other materials because they protect our hands from infection and contamination. Protective gloves should be selected on the basis of the hazards involved. ·  Nitrile gloves protect against most chemicals and infectious agents. ·  Rubber gloves protect against mild corrosive material. ·  Neoprene gloves protect against most solvents, oils, and mild corrosive materials. ·  Avoid latex gloves as many people are allergic or develop allergies to this material. When to Wear Gloves Wear gloves when your hands may come into contact with: ·  infectious materials ·  radioactive materials ·  chemicals When NOT to Wear Gloves ·  Don't wear gloves when touching common surfaces, such as telephones, computers, door knobs, and elevator buttons, or that may be touched without gloves by others. ·  Don't wear gloves outside of the lab. When transporting hazardous materials between labs, use s

Non-contact Infrared Thermometers

Measuring a person’s temperature can be done in several ways. One method to measure a person’s surface temperature is with the use of non-contact infrared thermometers (NCITs). NCITs may be used to reduce cross-contamination risk and minimize the risk of spreading disease. While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that "normal" body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers. Improper use of NCITs may lead to inaccurate measurements of temperature.   Benefits of NCITs Non-contact approach may reduce the risk of spreading disease between people being evaluated Easy to use Easy to clean and disinfect Measures temperature and displays a reading rapidly Provides ability to retake a temperature quickly   Limitations of NCITs How and where the NCIT is used may affect the measurement

FAQ – Use of gloves as protection against virus

图片
In order to achieve optimal protection from gloves, make sure you know which glove to use and how to use them. To help you, we’ve collected some of the most frequently asked questions about gloves as protection against virus. Should I disinfect the gloves before using them? No! It is never a good idea to disinfect gloves. Disinfection will break down the surface of the glove, allowing viruses and bacteria to penetrate the surface. Also, make sure your hands are completely dry before donning the gloves, especially when you have disinfected your hands before use. The alcohol must be dry before donning the glove. If the hands are very moist with alcohol, you can risk breaking the surface of the glove, making it easy for them to break when donning. How long is the breakthrough time for the virus on the glove - can a time be stated? It depends on the context in which the glove is used, which is why it is not possible to specify a permeation time in relation to the use of a glove against vir
