    What to do 1.
    Always minimize clutter
    .

    A decontamination bench is not a locker
    .

    The presence of debris impedes laminar flow around the work area
    .

    Plus, the mess makes cleaning work surfaces very difficult
    .

    2.
    Always wash your hands and arms before entering
    .

    People are the most critical source of contamination, and touch is the most common method of introducing contamination into sterile products
    .

    Proper hand washing is very important because there are countless bacterial components in your fingers
    .

    Hand washing should not only be done before, but also after, on the bench
    .

       3.
    Objects should be arranged in such a way that the full benefits of laminar air flow are fully obtained
    .

    Properly arranging everything in a laminar flow bench provides a work area that should be flushed directly with clean air from a ULPA filter
    .

       4.
    Avoid spraying or spraying the solution on the HEPA/ULPA filter
    .

    Do not allow any items to come into contact with the HEPA/ULPA filter so as not to pollute the downstream air
    .

       5.
    Remove the outer bag and wrap around the edges of the work area
    .

    Outer bags and wrappers are non-sterile items, which means they can introduce contaminants into the bench
    .

    They are also considered chaotic, so they can disrupt laminar airflow patterns
    .

       6.
    Do not put large objects behind the hood
    .

    Large objects can contaminate everything else downstream and can also disrupt laminar airflow patterns, suspending contaminants and removing them from the area
    .

       7.
    Keep coughing, move quickly and speak as little as possible in the main work area
    .

    Human activity generates particles
    .

    Particles disrupt the laminar flow of air, which can also be a cause of pollution
    .

    If talking is necessary, keep it away from the workbench
    .

       8.
    Be sure to sterilize the material before entering the laminar flow cabinet
    .

    Only place sterile materials in a clean work area
    .

    Make sure all items are properly sanitized so as not to contaminate the bench
    .

       NOT DO 1.
    Put any waste and other items in the hood
    .

    Waste and non-sterile items can cause airflow turbulence and introduce contaminants into clean benches and sterile samples
    .

       2.
    Wear any jewelry on hands and wrists
    .

    Jewelry are non-sterile items, so they can introduce bacteria or particles into a clean work area
    .

    They also reduce hand cleanliness if worn on a bench
    .

       3.
    Keep critical items away from air sources
    .

    Maintain a direct open path between the filter and the interior area of ​​the cooker hood where the work program is carried out
    .

    The air downstream of non-sterile items is contaminated with particles produced by these items
    .

       4.
    When opening the ampoule or adjusting the syringe, aim near the filter
    .

    Salt solutions in ampoules and syringes can deposit on HEPA/ULPA filters, which can damage the filter
    .

       5.
    Bring unnecessary items to the main work area
    .

    The introduction of unnecessary items into the work area should be avoided as much as possible
    .

    Traffic flow into the clean area should be minimized
    .

       6.
    Place large objects near the rear of the cabinet as they can disrupt the laminar flow pattern of the air and contaminate everything downstream
    .

    7.
    Use non-sterile materials
    .

    Unsterilized materials introduce contaminants into a clean bench, thus defeating the primary purpose of a decontamination bench, which is to protect your product from indoor contaminants
    .
