I am wondering if everyone could answer a question on Environmental
Monitoring in hoods
1) Do you shut off your laminar flow hoods or Biosafety Cabinets when no
one is in them? If so what is the policy of being allowed back in the
hoods upon start up?
I have been around enough to have seen a couple different way a)
hood shut off no ultraviolet lights, 30 minutes start up before allowing
anyone in hoods b) blower shut off,ultraviolet lights on, 30 minutes start
up of blower before allowing anyone in hoods c) blower on, ultraviolet
light on, no time delay after turning normal lights on.
