Nomex gloves should be worn over disposable gloves when working with pyrophoric chemicals, for example, such as tert-Butyllithium.
Reusable gloves are required for work involving immersion or direct contact with a chemical. Reusable gloves are also required when handling toxic or corrosive chemicals. Consult the Ansell Chemical Resistance Guide to choose the best glove.
