Working in a lab means you are going to be working with substances that just aren’t good for your health. This might be infectious agents or chemicals. In both cases, the risk may be very low or it may be extremely lethal or anything in between.
The most common vectors for entry into your body are through the skin, inhalation or ingestion. We will be focusing here on the skin vector and specifically on hand protection.
In all the years I have been dealing with labs, I can only think of one occasion where people were doing actual testing to see if the gloves they were using would actually protect the wearer!
