Permeable cloth coats and gowns are suitable for patient contact or laboratory procedures where contamination will probably be light and penetration of the garment by contaminated fluids is unlikely. Fluid-resistant gowns or aprons offer a greater degree of protection if soiling is likely to be heavier. If heavy soiling should occur, the wearer must be able to promptly remove the soiled garment before penetration by contaminated fluid occurs. Impervious gowns and aprons tend to be heavier and more uncomfortable, but offer secure protection from heavy soiling by contaminated fluids as could occur during bloody surgical procedures or autopsies. Then we have masks.
Surgical masks protect the wearer from liquid droplets and fluid splatters.
They are typically used during surgery, invasive procedures, intubations, and bronchoscopies for the safety of both patient and healthcare worker. This type of mask is required when working with patients with TB, changing demistifier tent filters, performing diagnostic sputum inductions or bronchoscopies, or administering some aerosolized medications. Users of these masks must be trained in their fit and use and their training documented. Face shields, including safety glasses or goggles, will protect the mucous membranes of the eyes, nose, and mouth of the user from splattering of blood or contaminated fluids. Use these during any drilling or other procedure where spraying or splattering of contaminated fluids is possible.
