incubator
General safety instructions on installing and operating the CO
2
incubator
1.2.
Indications for using pressure cylinders
1.2.1.
During the operation of the CO
2
incubator, small amounts of CO
2
enters the room, which in high
concentration can be life-threatening. The unit does not emit CO
2
when the power supply is
switched off and the gas cylinder valves are closed.
The CO
2
incubator can’t be operated near concentrated acids or corrosive vapours.
The workplace must be properly ventilated.
Emergency shutdown of the CO
2
dosing: close the gas cylinder valve.
The amount of dispensed CO
2
is regulated by a microprocessor controller. If the chamber door is open during CO
2
dosing,
the gas will be automatically cut off.
Together with a pressure cylinder with compressed gas, the user should be given a safety data sheet for the gas and
instructions for its use.
The ventilation performance in the room must ensure level of gas concentrations in the room below the limit values.
High concentration of CO
2
(>4 Vol.-%)- risk of death by suffocation.
During gas intake from the gas cylinder, check the pressure level regularly.
Characteristics of carbon dioxide
1.2.2.
Carbon dioxide (CO
2
) is colorless and odorless gas, therefore it is practically imperceptible. CO
2
is heavier than air and soluble
in water.
Warning signs on the bottle containing CO
2

Non-flammable and non-toxic gases
Pressurised gas
