Protection is needed from chemical and biological hazards when cleaning contaminated instruments. Use processes to reduce aerosols by manually scrubbing items under the water line, keeping lids on pans and ultrasonic tanks, and avoiding high pressure sprayers during rinsing. Enzymes in the ProEZ 2 work by breaking down organic soils, therefore they are potential irritants to eyes, skin and if inhaled. At a minimum workers should wear protective eyewear and water resistant non-latex gloves. (Because latex is protein, latex gloves are not recommended during manual cleaning of instruments.) In addition, a mask will reduce exposure to aerosolized infectious material and enzyme detergent. Use of a protective gown will prevent splashed soils and detergent from being transmitted on clothing that may be worn out of the facility.
