Personal protective equipment (PPE)

PPE is the last line of defense, not the first. In the Hierarchy of controls, elimination, substitution and Engineering controls come before PPE because they remove or reduce the hazard at its source, while PPE relies on the wearer using the right equipment correctly every time. Where hazards remain, PPE is still essential.

Choosing PPE starts with the SDS. Section 8 recommends protection, and the hazards in Sections 2, 9 and 11 explain why. A splash hazard points to Chemical splash goggles, a skin hazard to Chemical-resistant gloves, and an airborne hazard may require a Respirator. Workplace rules expect employers to assess hazards, select suitable equipment, train workers and make sure the gear fits.

No single item protects against every chemical. A glove that works well for one solvent may fail quickly with another, and a dust mask is not a substitute for a chemical respirator. Manufacturers' selection charts and test data on Breakthrough time help match equipment to a task.

PPE must also be maintained. Damaged items should be replaced, reusable items cleaned and stored properly, and contaminated gear removed in a way that avoids spreading the chemical. The idea of Decontamination applies to PPE as well as people.
