What is Carbon Dioxide?
• Colourless and odourless – CO2 is undetectable by human senses in small concentrations.
• As CO2 is heavier than air, – it collects at the bottom of confined spaces.– It will remain there forever unless dispersed.– Tends to build up over a period of time.
• Breweries tend to have high background CO2 levels.– This can be up to 2%
CO2 – How it affects your body5000 ppm 0.5% The normal international Safety Limit.
10,000ppm 1% Your rate of breathing increases very slightly.
15,000ppm 1.5% The normal Short Term Exposure Limit.
20,000ppm 2% You start to breathe at about 50% above your normal rate. Prolonged exposure can cause headaches.
30,000ppm 3% You may feel a bit dizzy at times; your heart rate and blood pressure increase and headaches and even your hearing can be impaired.
40,000-50,000ppm 4-5% Breathing is much faster and after only 30 minutes exposure to this level you will show signs of poisoning and feel a choking sensation.
50,000-100,000ppm 5-10% You will start to smell carbon dioxide. You will become tired with labored breathing, headaches as well as impaired vision and will lead to unconsciousness.
100,000ppm-1,000,000ppm 10-100% Unconsciousness occurs more quickly, the longer the exposure and the higher the level of carbon dioxide, the quicker suffocation occurs.
In a brewery your staff are breathing harder than normal and their
concentration is reduced
At this level your staff are potentially being
harmed
Sources of Carbon Dioxide in Breweries and Bars
Fermentation in Breweries
Drinks storage areas and cold rooms
Gas storage areas
Grain store
Reported incidents
Carbon Dioxide (CO2) is a toxic gas and is used frequently in theDrinks industry to carbonate drinks.
Each year, there are a number of accidents involving Carbon Dioxide – each story can be viewed on the Analox website.
• CO2 leak from Croatian brewery kills man• Carbon Dioxide - cellar service• Carbon Dioxide safety warning following death of US Midwest delivery driver• Toxic gas kills second worker• CO2 Fatality in brewery in Munich, Germany
What are your safety precautions?
Carry out a risk
assessment
