Safety Considerations
This set is intended to be used by teachers,
and their students while working under
appropriate supervision.
Generally...
Please teach and expect safe behavior in your
classroom and lab. Safety considerations call for
supervision of students at all times, use of safety
eyeware, no horseplay, no unauthorized
experimentation, immediate reporting to the instructor
of accidents or breakage, among others.
More Specifically...
Any liquids entering the pump are apt to be discharged
as a mist or spray. Only safe liquids such as water
should be allowed to be used in association with the
pump, and safety eyeware is definitely required.
The bell jar should be used only with the bottom plate
furnished. Attempting to evacuate the chamber while
in contact with other surfaces could cause damage.
Severe injury will result from evacuating the chamber
while in contact with skin.
Do not put items in the bell jar that would be damaged
by, or cause damage as a result of, reduced pressure.
Examples would include sealed containers, wrist
watches, batteries, etc. Certainly animals should not be
placed in the bell jar, for reasons of law and human
decency.
Do not use the apparatus if the bell jar or bottom plate
have become cracked or otherwise damaged.
