Safety Precautions
Although the laboratory hood has been engineered to
maintain optimum operator safety, caution should always
be used while working in the hood. Prior to using the hood,
check to make sure that the exhaust blower is operating
and that air is entering the hood at its specified face
velocity.
USE GOOD HOUSEKEEPING IN THE HOOD AT ALL
TIMES. CLEAN UP SPILLS IMMEDIATELY WITH A
MILD DETERGENT. PERIODICALLY CLEAN HOOD
INTERIOR, INCLUDING FLUORESCENT LIGHT GLASS
PANEL. REPLACE BURNED OUT LIGHT BULBS TO
MAINTAIN MAXIMUM ILLUMINATION.
DO NOT OVERLOAD THE WORK SURFACE WITH
APPARATUS OR WORK MATERIAL. THE SAFE
OPERATION OF THE LABORATORY HOOD IS BASED
UPON HAVING PROPER AIRFLOW THROUGH THE
STRUCTURE. DO NOT PLACE LARGE, BULKY
OBJECTS SUCH AS BLOCK HEATERS, DIRECTLY ON
THE HOOD WORK SURFACE. INSTEAD, ELEVATE THE
OBJECT 2" TO 3" ON BLOCKS TO ALLOW A FLOW OF
AIR UNDER THE OBJECT AND INTO THE LOWER REAR
BAFFLE EXHAUST SLOT. ENSURE BLOCKS ARE
LEVEL AND SECURED IN PLACE.
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.
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.
