  • 1. 1. 1. Clean35

    Cleaning removes pathogens and dirt Sanitation reduces the number of disease-

    causing organisms to non-threatening levels Disinfection destroys microorganisms, does not

    kill all pathogens Sterilization kills

    all disease-causing pathogens

  • 1. 1. 1.You NEED to know36

    1. What are you doing?2. What product?3. What are you killing?4. What are you treating?5. What concentration?6. What length of time? 7. What next?

  • 5 billion pounds cleaning chemicals annually(25% hazardous substances)

    One custodian uses, on average, 194 pounds of chemicals / year

    Custodians and teachers experience some of the highest rates of occupational asthma

    Custodians37

  • 20% burns to the eyes or skin

    12% inhaling vapours

    Norovirus is leading cause of food-borne illness

  • 1. 1. 1.

    51

    Found in vomit or stool even before a person is sick, and for 2-3 weeks after symptoms abate

    Alcohol-based hand sanitizers used in addition to hand washing

    Hand washing is critically important

    Highly contagious Caused by Staphylococcus aureus and/or

    Streptococcus pyogenes Red sores on the face, around nose, mouth,

    hands and feet Sores burst and develop

    honey-colored crusts Itchy

    52

  • MRSA Methicillin-resistantStaphylococcus aureus

    Spread through cuts, abrasions and skin-to-skin contact

    Contaminatedsurfaces

    Begins as painful/itchy boil

    53

  • Managing methicillin-resistantStaphylococcus aureus

    Survives 7 days - 7 months on dry surfaces Exclude students with wound drainage

    from sports Enforce hand hygiene Cover sores

    54

  • Clostridium difficile (C-diff)

    After antibiotic therapyDiarrhea Pseudomembranous and toxic colitis FeverAbdominal painCrampingNausea and loss

    of appetite

    Spores highly resistant to cleaning agents Survive for 5 months on dry surfaces HandwashingKilled by

    chlorine bleach

    Isolate infected individuals
