Glutaraldehyde
/ Endoscopy Fume Hoods
 Molecular
filters have proven effective for control of Glutaraldehyde fumes.
In fact, a standard filter will absorb the fumes from about 8000 disinfections.
That capacity guarantees personnel protection for 18 months in most day
surgeries.
Replacement disinfectants
(orth-phthaladehyde, OPA, peracetic acid) still require fume control,
even if they have no smell. Endoclean fume hoods are ideal. the filters
also absorb a broad spectrum of other chemical odours such as alcohol.
Recirculating
Fume Hoods chemically filter and recirculate air. There is no additional
burden on heating or cooling systems, or HEPA filtered air supply to the
operating suite.

Caution for Manual
Endoscope Disinfection Methods:
- A well designed
fume cupboard or fume hood will protect operators from glutaraldehyde
fumes generated when manually disinfecting endoscopes. However, the
protection is only assured while chemicals remain inside the
fume chamber. Operators should be aware of the hazards which can arise
from manual reprocessing methods.
- Decanting the disinfectant
can produce spills, or dribbles of solution on the outside of the container.
Any glutaraldehyde solution spilled outside the fume chamber will increase
exposure of all personnel to fumes. All spills or spots must be cleaned
up promptly. The used container must be sealed, and rinsed off, then
disposed of carefully.
- Drops of disinfectant
may also be spilled when removing scopes from the disinfectant bath.
Scopes must be thoroughly rinsed and all channels flushed within the
fume chamber.
- Gloves used for
personnel protection become infused with glutaraldehyde. If the gloves
are stored outside the fume chamber, evaporation can cause unnecessary
exposure to fumes.
These are powerful
arguments for automating the process, to eliminate operator contact with
the disinfectant.
