If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain viruses and bacteria. Surgical ...
An infographic on the difference between surgical masks and N95 respirators OSHA considers certain healthcare and mortuary workers to be at high or very high categories of exposure risk. High exposure risk jobs include healthcare delivery, support, laboratory, and medical transport workers who are exposed to known or suspected COVID-19 patients.
Therefore, OSHA standards require to restrict using of half-mask negative-pressure respirators up to 10 PEL after obtaining fit factor greater than or equal to 100 during the mask selection for the worker (they used a safety factor = 10).
