Nitrile chemical resistant gloves are often less expensive than other gloves and have superior chemical resistance. A wider range of applications than conventional gloves. The chemical-resistant glove’s workhorse is nitrile.
Thickness and length
Gloves with a thicker gauge are heavier and have superior chemical resistance than those with a thinner gauge. Thinner, lighter gloves provide higher touch sensitivity and flexibility at the expense of chemical resistance. According to glove makers, doubling the thickness of a glove quadruples the chemical’s breakthrough time.
The thickness of nitrile chemical resistant gloves is measured in mils or gauges. A 10-gauge glove has a thickness of 10 mils or 0.010 inches.
Finishes and linings
Gloves come in a wide range of coatings and linings. Gloves with textured coatings are used to improve grip. Flock and knit linings are available on a variety of glove models. For basic perspiration absorption, cotton flock linings are used. Knit linings perform the same thing, as well as providing some temperature protection.
Other job hazards, such as a potential cut or abrasion hazard, must also be considered in the hazard assessment.
Although the number of nitrile chemical resistant gloves options can be overwhelming, it’s vital to remember that gloves are never a substitute for safe work practices or effective engineering controls.
Choosing a glove material
No one glove is suitable for all chemical exposures because different glove materials resist different chemicals. A glove that works well in one situation may not work well in another. It’s advisable to choose nitrile chemical resistant gloves based on the chemical resistance advice provided by the manufacturer. Choose the glove that is most resistant to the chemicals being used from the instructions.
According to a consultant for QRP and Guardian, nitrile chemical resistant gloves should not be used with ketones, strong oxidizing acids, or organic substances containing nitrogen. Nitrile is also known for having a low flame resistance.
