Full Face Dust Respirator – Finally, full-face dust respirators can protect workers from exposure to up to 50 times the OSHA PEL. These are required when a mason is tasked with grinding mortar prior to tuck-pointing. Typically these are used in enclosed and confined spaces where dust can accumulate quickly and in large quantities.
