1. Adjust the seating position so that the user's face is above the front opening. Adjustable stool is
recommended.
2. Turn on the fan. Leave the cabinet on for 5 minutes before beginning work in order to purge airborne con-
tamination from the work area.
3. Prepareawrittenchecklistofmaterials/apparatusnecessaryforimmediateusageandsurface-decontami-
nate before loading them into the work zone. This is to prevent overloading and to minimize the number of
armmovementsthatmightdisrupttheairow.
»Neverusethecabinettostoresuppliesorlaboratoryequipment.
»Keep the back air grilles unobstructed by arms or objects.
»Always surface-decontaminate all items before inserting into the work zone.
4. Load and arrange the materials/apparatus to minimize the movement of contaminated items over clean
items by segregating the contaminated items from the clean items.
5. A clean, long-sleeved laboratory coat may be used to protect personal clothing.
6. Washhandsthoroughlyusinggermicidalsoap.Wearglovesforhandprotection.Glovesshouldbepulled
over the knitted wrists of the gown rather than worn inside.
7. Minimize room activity (personnel movements, closing and opening doors, etc.).
4.3WorkingInTheCabinet
1. Work from clean to dirty by following the segregation of clean and dirty materials/apparatus as described
in the Start-Up Procedure above.
2.Particularlycriticalobjectsmaybearrangedsuchthatairowsdirectlyagainstthemwhilethebackair
grilles remain unobstructed by arms or objects.
3.Donotuseagasame,ifpossible,asitinterfereswithairow.
4. Do not use writing materials inside the work area as they generate aerosols.
5. Do not change the original blower speed of the cabinet unless the change is required by a decrease in
measuredairvelocity.Adjustmentshouldbemadeonlybyaqualiedtechnician.
6. Do not operate the cabinet if fan fails to run.
7. Do not cough or sneeze into the work zone.
8.Minimizearmmovement.Movearmsinandoutofthecabinetslowlytoavoiddisruptingcabinetairow.
9. Use absorbent pads on the work surface where appropriate to minimize splatter and aerosol generation in
case of spillage.
10. Clean materials should be at least 150 mm away from aerosol generating objects to minimize the chance
for cross contamination.
11.Holdlids/coversabovedishes/sampleplatesinordertopreventairimpingementwhereappropriate.
12.Arrangeobjectstoavoidairowturbulence.
13.Keeparmsasfarawayaspossiblefromitemsintheworkzone.
