Some tasks may require only splash protection or include intermittent contact, while others may involve complete immersion or continual contact with the chemical. Other factors to consider are chemical concentration and temperature. The higher the concentration and temperature of a chemical, the shorter the breakthrough time. The hazard assessment will also take into account other hazards of the job, such as cut or abrasion hazards. It's important to remember that although the number of glove choices can be staggering, no one glove can possibly address all types of hand hazards.
Gloves are never a substitute for safe work practices or proper engineering controls.
A glove that is suited well for one application may prove dangerous for another. From this guide, choose a glove that is most resistant to the chemicals being used. Remember, the actual chemical compatibility of a given glove material can vary from manufacturer to manufacturer. Another factor to consider is chemical combinations. Other choices you must make in selecting chemical protective gloves include thickness and length.
