1. It is the responsibility of the user to determine the suitability of this
product for the intended applications. Consult your Safety Officer for
application review.
2. Although the glove box has been engineered to maintain optimum
operator safety, caution should always be used while working. Prior
to using the glove box, check to make sure that the main chamber
pressure is set for comfortable glove manipulation. Changes in glove
position will affect pressure in the glove box.
3. Use good housekeeping in the enclosure at all times. Clean up spills
immediately. Periodically clean enclosure interior per your standard
operating procedures for the specific chemicals in use.
4. This product is not designed or intended to be explosion proof. It is
the responsibility of the user to determine and avoid the lower
explosive limits and flammability of the enclosed gases used within
the controlled atmosphere glove box. The user is responsible for
taking proper precautions to prevent equipment damage or injury due
to an explosion or combustion of chemicals.
5. The use of flammable gases or solvents in the glove box should be
limited. Care must be taken to ensure against the concentration
buildup of flammable or explosive gases or vapors. Use of an open
flame or exposure to high heat should be avoided in the glove box as
the heat will damage the liner. DANGER: Use of added oxygen
inside the glove box must be avoided to prevent explosion, death,
or serious injury.

is initially used.
9. The glove box should be recertified at least annually after installation.
10. The use of safety goggles, protective clothing, and any other personal
protective equipment recommended by your safety officer should be

11. The pressure relief valve provides protection from over or under
pressurization and should be filtered and/or ducted to the outside
if working with hazardous materials. Consult your Safety Officer.
When operating the transfer chamber gas inlet and vacuum outlet
valves, insure the inner transfer door is closed. Failure to do so can
result in the pressure relief valve opening, thereby, introducing
laboratory air into the glove box main chamber or glove box air into
the laboratory.
