Safety Labels
The symbols used on the machine were developed by the International Organization for Standardization
(ISO) and are defined below. These symbols may include yellow warnings triangles, blue mandatory action
circles, or red prohibited action circles.
Danger of Suffocation
Dry ice pellets are CO
2
in solid form. At ordinary atmospheric pressure, CO
2
can only exist in this solid form
at temperatures of -78.9°C (-109°F) or lower. Therefore, during dry ice production and blasting, the CO
2
will
immediately be heated and thus transform from solid form into gas form.
Please note:
Since the specific gravity of CO
2
is higher than that of ordinary atmospheric air, the air with its contents of
oxygen will be replaced by CO
2
if the dry ice production is taking place in small or insufficiently ventilated
rooms.
Therefore, please note the following:
1. Low CO
2
concentrations (3-5%) cause headaches and fast breathing.
2. CO
2
concentrations of (7-10%) cause headaches and nausea and may result in unconsciousness.
3. Higher CO
2
concentrations result in unconsciousness and at worst, may cause suffocation.
High CO
2
concentrations may result in unconsciousness due to displacement of oxygen. Therefore, always
make sure to provide sufficient ventilation of the working area, and always avoid producing dry ice in small
rooms.
