9. Risk Assessment operating DALUM CO
2
Systems
9.1 Chemical hazards:
The DALUM CO2 recovery system contains substances in the form of activated alumina
desiccants and activated carbon in small amounts and in qualities approved for
purification of food grade CO2.
Handling
Exposure to these chemicals could cause skin irritation, eye irritation, and respiratory
problems from dust. The desiccant and carbon needs replacement with only 1 year’s
intervals and the volumes are very small but it is still important to wear appropriate
protective equipment to avoid direct contact with or inhaling the substances when
replacing it. Avoid the formation or spread of dust in the air and smoking during work.
Storage
Store in a dry and cool place in original container. No other precautions are necessary in
the small amounts handles for DALUM CO2 Units. Desiccant has no hazardous
marking, but activated carbon can burn and is toxic to aquatic life.
First aid measure
After contact with eyes or skin wash with plenty of water. If inhaled keep calm and
remove to fresh air. If swallowed rinse mouth and drink plenty of water.
Disposal
Disposal of the substances in accordance with local regulations as inorganic
substances.
Do not discharge waterways or sewer systems. Activated carbon is toxic to aquatic life.
9.2 Carbon Dioxide Hazards:
Carbon dioxide (CO2) can create a hazardous atmosphere.
Carbon dioxide is for beverage purposes used as a gas, but for other purposes in liquid
form or solid (dry ice). In the gaseous state CO
2
is odorless, colorless and tasteless
making it undetectable to persons in areas with hazardous concentrations of CO2.
Exposure to carbon dioxide can lead to posing risks to workers and create asphyxiation
hazards in poorly ventilated areas, even with the presence of oxygen in atmospheric
concentrations. Gaseous CO2 is heavier than atmospheric air and will collect at floor
level and low-lying spaces.
Liquid CO2 and dry ice
Liquid CO2 and dry ice are extremely cold and can freeze tissue on contact. If
swallowed liquid CO2 and dry ice cause serious injury or death.
Precautions:
Monitor and ventilate for CO2 where CO2 can accumulate.
