There are a few different types of gloves that you can purchase for work and safety purposes. The most common gloves are made of latex, nitrile, or vinyl. You can usually find these gloves at your local hardware store. If you need a more specialized glove, such as one that is Kevlar lined or has a special grip, you may need to purchase it from a specialty retailer. In general, you do not need a certificate to purchase gloves.
