Chapter 4: Performance Features and Safety Precautions
Blocking the bottom of the baffle
at rear of hood will change the
airflow pattern in the hood causing
turbulence and possible leakage at
the face of the hood. (Don’t store
containers or supplies against
baffles, as this will affect airflow
through the hood).
Avoid placing your head inside
hood. Keep hands out of hood as
much as possible.
Always work as far back in hood
as possible. It is best to keep all
chemicals and apparatus 6" inside
the front of the hood.
On vertical-rising sash models,
always close the rear sash for
proper airflow; on horizontal-
sliding sash models work in the
minimum required opening for
maximum safety.
This hood does not feature
explosion-proof electrical
components, unless ordered
separately. Therefore, use of
flammable or explosive materials
in quantities above the explosive
limit are not recommended.
Do not work with chemicals in this
hood without the exhaust system
running. Do not store chemicals in
a fume hood.
Perchloric acid use in this hood is
prohibited.
High-level radioisotope materials
are prohibited for usage in this
hood.
