Before choosing the right glove, it is essential to be familiar with the applications in which gloves will be used. It is also important to understand what level of protection is required. For example, if you are holding hot sheets of metal, it is important to know how hot the metal will get. That will determine whether a 400 degree glove is sufficient or if a glove with a higher temperature rating will be necessary. For chemical-resistant gloves, it is important to know what chemicals and concentrations are being used. There are various glove materials available, each having specific benefits.
