Most antimicrobial chemical agents are too irritating and destructive to be applied to mucous membranes and skin. Those that may be used safely on human tissues are called antiseptics. An antiseptic merely reduces the number of organisms on a surface; it does not penetrate pores and hair follicles to destroy microorganisms residing there. To remove organisms lodged in pores and folds of the skin, healthcare personnel use an antiseptic soap and scrub with a brush. To prevent resident indigenous microbiota from contaminating the surgical field, surgeons wear clean gloves on freshly scrubbed hands, and masks and hoods to cover their face and hair. Also, an antiseptic is applied at the site of the surgical incision to destroy local microorganisms.(1 Point)TrueFalse
