GENERAL SAFETY NOTES
GENERAL
This instruction manual contains important information necessary for installation, connection,
setting and use of this product for safe and reliable operation and must therefore be read and
understood thoroughly before putting the product into operation for the first time. Since an
ASCO product is generally used in conjunction with other equipment, the following safety notes
are correspondingly more comprehensive.
DRAWING AND SYMBOLS
Many accidents on and with machines are caused by failure to observe the manufacturer’s
instructions and the safety notes. International signs and symbols draw attention to the hazard
situations in the working environment. You will find the following symbols, among others, in the
instruction manual of your ASCO product.

GENERAL SAFETY NOTES
RISK OF ELECTRIC SHOCK
DANGER
Risk of electric shock. Service works, maintenance and deinstallation may only
be performed on de-energized equipment and with disconnected power plug.
QUALIFICATION OF OPERATOR
WARNING
It is mandatory that operators are trained by an authorized person (operating
company or manufacturer) in the following issues:
• safe handling of dry ice and / or liquid / gaseous CO2
• operation of ASCO equipment
• safety precautions / safety equipment
• protective clothing
INTERACTING MACHINE PARTS
CAUTION
Many ASCO appliances are mechanically driven machines. Moving parts pre-
sent a corresponding danger.
The service openings as well as the side - and rear walls must always be closed during ope-
ration so that moving parts cannot be reached. Please ensure that these lids are always fitted
before the machine is commissioned.

GENERAL SAFETY NOTES
FURTHER SAFETY MEASURES AND INFORMATION
WARNING
Dry ice "sublimates", i.e. it goes directly over into a gaseous state without be-
coming liquid, therefore do not store in hermetically sealed containers. Please
observe that 2.2 lbs (1 kg) of dry ice at 15 psi (1 bar) ambient pressure corres-
ponds to a volume of approx 17.7 ft3(0.5 m3) CO2gas.
Generally it is assumed that all CO2liquid pipes are pressurised. After the end
of production the pipes must be emptied or depressurised. It must be ensured
that all pipes are resealed again in order to prevent ingress of damp.
Please ensure that your ASCO product is always installed on a level industrial
floor.
Ventilate the production areas frequently and well.
CAUTION
In order to avoid accidents with "shooting" pellets on start up, it must be ensured
that the pellet ejection area is completely clear. While the plant is in operation,
never look directly at the pellet exit.
CAUTION
If the tank and the appliance are switched off together, the pipe safety valve can
react under certain circumstances.

OVERPRESSURE IN PIPES
If two shut off valves are connected on a CO2liquid pipe, a safety valve must always be ins-
talled between the valves. If liquid CO2is trapped in the pipe between two shut-off valves, then
the pressure in the pipe, triggered by the rapid expansion of CO2due to heating, can increase
very quickly.
WARNING
For this reason there is a danger of damage to persons or material damage as
the pipe or the hose could burst in the worst case scenario.
• Therefore it is extremely important that a safety valve is fitted anywhere where
liquid CO2can be trapped.
• In addition it is recommended to fit a discharge cock/ball valve so that CO2can be
released when required.

CO2SAFETY NOTES
The following safety notes refer to the handling of carbon dioxide in its three aggregate condi-
tions:
1) Gaseous CO2
2) Liquid CO2
3) Solid CO2(also known as "DRY ICE")
FREEZE INJURIES
DANGER
Dry ice has a temperature of approx -110.2 °F (-79 °C) and it can lead to freeze
burns if it comes into contact with inadequate protective clothing. Dry ice must
not be taken orally under any circumstances. Keep away from children!
CAUTION
Metallic parts, such as CO2pipes, may only be touched if appropriate protective
clothing is being worn. Frozen metal parts can give freeze burns if they come
into contact with the skin. Unprotected skin can "stick" to frozen parts.
DANGER OF CARBON DIOXIDE POISONING
Please ensure that your ASCO quality product is always set up in a well-ventilated area.
WARNING
An increase in carbon dioxide concentration in the ambient air affects breathing.
The carbon dioxide can no longer be discharged from the blood or the alveoli and this means
there is no space for oxygen in the blood this leads to a toxic reaction.

CO2SAFETY NOTES
This effect of the carbon dioxide is described as poisoning. The effect of carbon dioxide poiso-
ning is completely independent of the effects of a lack of oxygen. The content of oxygen in
the atmosphere is thus not an effective indication of danger. It is definitely possible to
have an acceptably low oxygen concentration of 18 % in the ambient air and an increased
carbon dioxide concentration at the same time which signifies a dangerous situation.
The individual tolerance values can vary strongly depending on the physical condition
of the people and the temperature and air humidity ratios of the atmosphere, but the
effects mentioned below will generally occur if various carbon dioxide concentrations are in-
haled.
1 - 1.5 % Light effect on the chemical metabolism following exposure over several hours.
3 %
In this concentration the gas has a weak narcotic effect and it causes deeper
and quicker breathing and poorer hearing ability along with headache, increa-
sed blood pressure and a quicker pulse.
4 - 5 % Stimulation of the breathing centre and resultant deeper and quicker breathing.
After 30 minutes exposure the appearance of poisoning becomes apparent!
5 - 10 % Breathing becomes more of an effort with headache and loss of judgement!
10 - 100 %
If the carbon dioxide concentration goes above 10 %, loss of consciousness will
occur in less than 1 minute - and if no immediate measures are taken, further
exposure to such high values can result in death.
The effects of inhaling carbon dioxide in low concentration are physiologically reversible but in
higher concentrations the effect is toxic and damaging!
WARNING
Heart and breathing defects can increase the danger of carbon dioxide poiso-
ning.
ASCO CARBON DIOXIDE LTD supplies appliances for continuous monitoring of the ambient
air in the danger area. These display the current CO2concentration and give an acoustic war-
ning when the set highest concentration values are reached.

CO2SAFETY NOTES
INFORMATION FOR SAFE OPERATION
Storage and transport Liquid CO2is stored at temperatures between -18.4 °F (-28
°C) and 1.4 °F (-17 °C), depending on the storage pressure.
Danger of fire/explosion CO2is not flammable and it is used as a fire extinguishing
agent.
EFFECTS ON HEALTH
DANGER
Swallowing solid or liquid CO2causes serious internal burns. Swallowing larger
amounts of gaseous CO2causes intestinal irritations due to the formation of bad
carbonic acid compounds!
WARNING
Gaseous CO2causes light eye irritations through the formation of bad carbonic
acid compounds. Liquid and also solid CO2causes serious freeze burns and
can lead to blindness.
FIRST AID
Swallowing Get medical assistance IMMEDIATELY.
Eyes Rinse the eye with plenty of warm water and get medical as-
sistance IMMEDIATELY.
Skin Sprinkle the skin with warm water for at least 15 minutes and
get medical assistance IMMEDIATELY.
Inhalation
In the case of fainting, move victim to a well-ventilated area
IMMEDIATELY. TAKE CARE: DO NOT EXPOSE YOURSELF
TO DANGER.
Get medical assistance IMMEDIATELY.
If breathing stops, give artificial respiration IMMEDIATELY
and get medical assistance.
