INTRODUCTION

JetChill Ltd supply products which enable entertainment operators to provide their
customers with smoking drinks.
Solid carbon dioxide (Dry Ice) is dispensed from a gas cylinder via a filling nozzle into
drinking vessels. Alcoholic/non-alcoholic beverages are then poured into the drinking
vessel creating a chemical reaction with the Dry Ice.
JetChill have endeavoured to ensure that their products are safe when used in
accordance with the instructions contained in this manual, JetChill have sought
independent evaluation on the safety of these products from Trading Standards, a UK
Public Analyst and a National Drinks Gas supplier who all confirm that the product when
used as intended poses no risks to health or safety.
JetChill Ltd cannot be held responsible for any injuries or claims, both civil and criminal,
caused by the use of the equipment and products contrary to these guidelines.
INTRODUCTION - Disclaimer

You are now the proud owner of JetChill equipment which will enable you to give your
customers a truly exhilarating experience when consuming certain alcoholic drinks.
JetChill drinks use dry ice (solid carbon dioxide gas) to react with room temperature
liquids to provide a smoking effect to the drink.
Dry ice is a‘food safe’ substance but there are health and safety hazards associated with
the very low temperature of this product, which means it must be handled with care.
Uncontrolled, exposure to dry ice will cause freezer burns to skin. Consumption of dry ice
crystals or pellets can cause burns to the oesophagus and stomach.
JetChill provides dispensing equipment certified by CE and NSF. This includes the carbon
dioxide cylinder, the ‘JetChill’ dry ice dispenser and the associated, safe drinking vessel
into which the dry ice is inserted under pressure. Finally, JetChill also provides the
alcoholic beverage which is dispensed into the drinking vessel. This user manual outlines
fully how the JetChill equipment is to be used safely.
Once small amounts of dry ice have been dispensed into the JetChill drinks vessel, the
alcoholic liquid is added by the server or by the customer. The chemical reaction
between the alcoholic beverage and the dry ice is almost instant and will last for several
minutes. The drink can be consumed at any point after the liquid has been added, during
the chemical reaction and after the subsidence of the chemical reaction.
Whilst small deposits of dry ice can be released into drinks during consumption, the risks
to health from these small amounts (a maximum of 0.05g per dispense) are not
considered to present a risk to the human health (see scientific data in the appendices).
Dry ice is dispensed into the bottom of the drinking vessel where it is kept separate from
the liquid by a perforated ‘separator’.It is this separator that prevents the dry ice from
being consumed by the customer. Where solid dry ice pellets are used, these are also
kept in a separate section of the drinking vessel so as to prevent accidental ingestion.
The dry ice is not considered to cause any food safety concerns and will not render the
alcoholic drink injurious to health, nor will it render it unfit for consumption. There are
safety hazards associated with the handling and use of the JetChill equipment, but no
more so those associated with the handling of cellar gases. Safe systems of work are
addressed in later sections of this manual.
It is essential that users of the equipment are suitably trained and can demonstrate they
are competent to use the equipment safely. Training information is contained in this
manual. It will be the venue operator/employer’s responsibility to ensure that all staff
and any self-employed or contracted personnel engaged to dispense the smoking drinks,
are competent to use the equipment.

INTRODUCTION - Acoura Overview
Acoura Ltd, Environmental Health Consultants with extensive experience in the leisure
and hospitality industry, were appointed by the Directors of JetChill to review the health
and safety hazards and risks associated with using equipment and solid carbon dioxide
powder to produce foaming or smoking drinks for consumption in the leisure and
entertainment markets.
The Directors wanted to ensure that the products they were providing to the
entertainment industry were inherently safe and unless operational procedures were
abused, would not cause harm to the operators producing the drinks or the customers
consuming the drinks.
Outcome of Review
Acoura Ltd, and in particular, Pat Perry, reviewed the procedures for creating the smoking
drinks.
The operation of the equipment was demonstrated.
The solid carbon dioxide substances were reviewed.
The procedures for mixing the drinks were reviewed.
Technical details e.g. Safety Data Sheets for the solid carbon dioxide were reviewed.
Research was carried out to establish whether solid carbon dioxide when used in the
entertainment drinks industry was the cause of numerous accidents. A review of on-site
procedures was undertaken by an Enforcement Authority in Newcastle and the officer
involved was contacted to establish whether he had any concerns over safety.
A comprehensive Health & Safety Information Folder was developed which JetChill could
distribute with its equipment thus providing the operators with information regarding
hazards and risks. Risk Assessments were completed which could be made ‘site specific’
by the site operators. Manufacturer’s information was reviewed and included in the
Manual.
Training material was evaluated and further developed so that every operator would
have definitive information to understand the hazards and risks and the tools to be able
to cascade the training to operators who would fill the drinking vessels with solid carbon
dioxide and liquids.
Conclusion
There is always an inherent risk associated with many activities i.e. there is the potential
to cause harm and the severity of that harm would be variable. There is an inherent risk
associated with using solid carbon dioxide - it has a temperature below minus 78oC.It
causes severe skin burns on impact. When mixed with liquid, Dry Ice (as solid carbon
dioxide is known) will sublime into a gaseous state which creates the ‘smoking’ effect.
Carbon dioxide gas is an asphyxiant and in high concentrations it may cause asphyxiation.

It is unlikely that the volume of gas generated from mixing the JetChill carbon dioxide
powder with an alcoholic/non alcoholic beverage will be harmful if inhaled.
The hazards associated with using the JetChill drinks dispensing System are considered to
be low provided all operators are trained, the correct equipment is used, including the
proprietary drinking vessels provided by JetChill and the correct operating procedures are
followed. The hazards of ‘ice’ burns - to skin and or throat (when drinking Dry Ice) is
controlled by the fact that the Dry Ice powder cannot be touched by the customer nor
inadvertently consumed because they are trapped in the bottom of the drinking vessel.
The Dry Ice powder also sublimates quickly once it comes into contact with a beverage.
The use of carbon dioxide as Dry Ice is not of the same risk as using liquid nitrogen. Liquid
nitrogen has been used in the production of ‘entertainment’ drinks and there have been
severe consequences for the end users. The use of liquid nitrogen is NOT advocated by
JetChill and its products do not contain any element of liquid nitrogen.
Overall Assessment Regarding Health & Safety Law
The use of solid carbon dioxide powder together with small quantities of alcoholic or non-
alcoholic drinks, when dispensed the suitable, proprietary, JetChill drinking vessels is
deemed to be LOW RISK in respect of harm to the end consumers.
The dispensing of solid carbon dioxide into drinking vessels and the mixing with liquids is
considered to be LOW RISK to operators provided they follow the safe operating
procedures, Risk Assessments and other instructions provided by JetChill.
The storage of carbon dioxide Cylinders creates risks of gas leakage/explosion should
Cylinders be stored inappropriately. Operators are expected to follow the safe operating
and storage procedures.
Appropriate steps have been taken to evaluate the risks to operators and end consumers
from dispensing and consuming drinks containing solid carbon dioxide and overall the risk
category is:
LOW

The drinking vessels provided by JetChill have been designed to be as indestructible as
possible if used in a reasonably everyday way. Extreme force will cause the vessel to
break but everyday use and some purposeful abuse e.g. crushing by foot, will not shatter
the product.
Because of the robustness of the drinking vessel it is considered unlikely that the
customer can come into direct contact with the dry ice and therefore the risk of frostbite
burns is minimal.
The drinking vessel is designed with a Safety Chamber in the Base into which the Dry Ice
is automatically injected into.
The Cocktail Glass has a removable cap in the base. This cap contracts when it comes
into contact with Dry Ice meaning it cannot be easily opened by customers by hand
which prevents direct contact with the dry ice. The cap is also concealed so it is not
obvious to customers that it can be unscrewed. The Shot Glass does not have a
removable base.
The drinking vessel can be washed in a standard glass washer and should be heat treated
to 80ºC to ensure thorough sterilisation.
Any damaged drinking vessels should be disposed of (local recycling schemes may apply).
The Glasses are made from food grade Polycarbonate.

DRY ICE/CARBON DIOXIDE CYLINDERS - Safe Use & Storage
1. Physical Properties and Handling
Gaseous state
At normal temperature (+15°C) and atmospheric pressure CO2has a density of 1.87
kg/m3 and is 1.5 times heavier than air. It is a colourless and odourless gas (with a slightly
pungent odour at high concentrations) and spreads along the ground collecting in low-
lying areas such as pits and cellar.
Carbon dioxide is classified as a nontoxic gas but it does start to affect breathing at
concentrations of about 1%, with affects becoming more serious with increasing
concentrations.
Carbon dioxide is a non-flammable gas.
Liquid State
Carbon dioxide can exist as a liquid below the critical temperature of 31°C and above the
triple point with a temperature of -56.6°C and 4.18 bar gauge (bar).
CO2is transported, stored and handled in liquid form, either at ambient temperature (in
cylinders or not insulated storage tanks at a pressure of 45 -65 bar) or refrigerated (in
insulated tankers and storage tanks) at a temperature range of -35°C to 15°C and a
pressure of 12 to 25 bar. The CO2in this state, is a liquid at its boiling point.
Below the triple point CO2 can only exist in the solid and gas phase. Therefore the liquid
CO2 cannot exist at atmospheric pressure. When the liquid CO2is depressurised below
the triple point pressure of 4.18 bar to atmospheric pressure it is transformed to dry ice
and gas. Consequently when the liquid CO2is released to the atmosphere a dense white
fog of powdery solid carbon dioxide particles and vapour is produced.
Solid state (Dry ice)
The expansion of liquid CO2to atmospheric pressure is used to produce CO2 snow at a
temperature of -78.5°C. The snow is pressed to dry ice blocks or pellets.
Dry ice is handled in insulated containers.
Chemical Properties
Carbon dioxide does not support combustion. When dissolved in water, carbonic acid
(H2CO3) is formed. The pH - value of carbonic acid varies from 3.7 at atmospheric
pressure to 3.2 at 23.4 bar.
.

The carbonic acid provides the biting taste of soda water and it reacts in alkaline solutions
producing carbonates. It has very few vigorous reactions with other substances except
under conditions of high temperature and pressure in the presence of reactive substances
such as sodium and magnesium.
For this reason carbon dioxide should not be used as a fire extinguishing agent for
reactive metals like sodium and magnesium.
2. Hazards of Carbon Dioxide
Substantial Release of Carbon Dioxide
Any substantial release of carbon dioxide is potentially hazardous especially inside a
poorly ventilated building. Enclosed low-lying areas, where CO2 gas could accumulate in
high concentration, are particularly hazardous because the gas is slow to disperse unless
the spaces are well ventilated.
In case of a substantial release of carbon dioxide in confined areas, evacuate all personnel
as soon as possible. Never enter such areas before they are properly ventilated.
When confined spaces must be entered before they are properly ventilated, the person
entering such areas must be well trained and wear self-contained air breathing apparatus.
Canister respirators give no protection in atmospheres containing dangerous
concentrations of carbon dioxide.
A second, also well trained person should be connected with a rope to the person
entering the gas filled area, for rescue purposes.
Substantial releases of carbon dioxide may occur through:
•Failure of the cylinder or pipe work containing carbon dioxide.
•Release from a relief valve or bursting disc.
•Inadvertent opening of a drain or vent valve while the system contains CO2.
•Failure of connections, e.g. flexible hoses, flanges etc.
•Failure of a regulating device resulting in gas release through the body vent holes.
Low Temperature of Product: Extreme Cold The snow produced from leaks of liquid
carbon dioxide is extremely cold (-78.5°C) and may cause frost bites if touched with bare
hands. If carbon dioxide snow comes into contact with the eyes it may cause severe eye
injury.
Touching of pipes and connections containing liquid carbon dioxide may cause frost bite.
Where there has been a major release of gas, the atmosphere will be very cold and
visibility is likely to be limited. These factors can make escape or rescue difficult.
