Fumigation method : Safety cabinet should be sealed prior before fumigation to ensure that no
formaldehyde leak into the laboratory or another room. Fumigation for safety cabinet and filter
should ensure that export of HEPA filter and piping systems exposed for more than 14 hours in order
to ensure that microorganisms that pierce the filter is inactivate . When half of formaldehyde is
evaporated, turn on cabinet fan running for 10s ~ 15s, making the whole area filled with
formaldehyde; After complete evaporation , and then turn on the cabinet fan once more running
for 10s ~ 15s. After the fumigation, Microbiological Safety Cabinet sealing device should be
