Before donning PPE for body-fluid exposure...

While wearing a mask is important for respiratory protection, it is not the first step before putting on PPE. Masks should be donned after hand hygiene has been performed to avoid transferring pathogens from the hands to the mask, which could compromise its effectiveness.

Donning a hair cover is part of proper PPE donning procedures, particularly in environments where contamination is a concern. However, like wearing a mask, it should occur after handwashing to maintain hygiene standards and prevent contamination.

Disinfecting skin is essential in certain medical situations, especially when preparing for procedures that involve body fluids. However, this step is not as foundational as handwashing prior to PPE donning. Handwashing should be prioritized to remove contaminants before any other protective measures are taken.
