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
