The unit contains liquid oxygen
which is extremely cold, almost
-300°F. Exposure to such a low tem-
perature can cause severe frostbite.

other materials to burn faster than
normal. This hazard, along with the
low temperatures of liquid oxygen,
warrants certain safety precautions.
Do not smoke near unit or while op-
erating unit
Keep unit well ventilated at all times
