Cleaning surfaces contaminated with blood, body fluids ALWAYS wear gloves and protective apron or clothing Be alert for sharp objects, broken glassware, used syringes in trash Do not pick up broken glass - use brush or broom & dustpan Dispose of glass, sharp objects safely Laundry - bloody or contaminated linens or sharp objects

31 Common Sense Rules Wash hands & remove protective clothing before eating, drinking, smoking, handling contact lenses, applying lip balm or cosmetics Keep hands away from eyes, nose, mouth while cleaning Frequent handwashing is best defense against spreading infection
