- Engineering controls such as containment, ventilation and material substitution provide the best means of chemical protection. However, chemicals must eventually be manipulated, transported or dispensed, which introduces the potential for dermal contact.
- This article focuses on an abstract method based on evolving polymer science that OSH professionals can use to rapidly screen and select polymer protective glove materials.
Most workers in the chemical and associated industries will come into close contact with a hazardous substance on the job, in the lab or during education. Consequently, interest in injury prevention remains high. Engineering controls such as containment, ventilation and material substitution provide the best means of chemical protection. However, chemicals must eventually be manipulated, transported or dispensed, which introduces the potential for dermal contact. Many users slip on the first pair of gloves they find, but a poorly selected glove can swell or dissolve within a few minutes. Conversely, gloves may cost $300 per pair, a high price to pay if a less expensive pair would suffice. So, the correct chemical/rubber match has a strong economic advantage. Therefore, elastomeric protective gloves are an important defense that must be selected systematically.
OSHA’s PPE (29 CFR 1910.138) and lab safety (29 CFR 1910.1450) standards require a methodology in selecting appropriate gloves. The agency’s Process Safety Management standard (29 CFR 1910.119) requires hazard assessments of PPE among many other elements. Analysis of potential release scenarios and human exposures requires the selection of the correct protective glove material, which can change depending on the scenario.
With multiple articles, books and vendor charts covering protective garments and gloves, this article focuses on an abstract method for matching the correct glove to the solvent in use. Permeation charts exist for some pure chemicals and a few mixtures, but the performance of glove polymers varies considerably with solvent. Also, charts may or may not suggest acceptable alternatives, as mixtures of solvents greatly complicate the issue.
