Anoxia: High expansion foam
– The Anoxia method is unique for creating an environment without oxygen under atmospheric circumstances
– High expansion foam is produced by mixing nitrogen and a mixture of water and specially developed high expansion detergent, with an expansion rate upto 1:1000, meaning that 1 litre of water/foam agent mix expands up to 1 m3 foam.
– Due to the specially designed foam generator, the high expansion foam bubbles are filled with a > 99% concentration of nitrogen
– The oxygen level surrounding the animal drops from 21% in atmospheric air to < 1 % once the animal is submerged in the foam
3For more information: www.anoxia.eu
• Atmospheric air contains 21% oxygen, 78% nitrogen and 1% other gasses, mainly carbon dioxide; the animal needs a constant supply of oxygen to the brain
• Applying Anoxia foam, the oxygen is replaced by nitrogen, raising the nitrogen level to > 99% and lowering the oxygen level to < 1%
• The natural reaction to sudden lack of oxygen is rendering quickly into unconsciousness, causing behavioural indicators like loss of posture and convulsions
• Unconscious animals are insensitive to perceive unpleasant sensations like pain
Anoxia: convulsions, but no stress or pain

Anoxia: How Anoxia foam is created
• A mixture of 97% water and 3% high expansion foam agent is sprayed into the Anoxia foam generator, creating a thin film on the outlet of the generator
• At the same time, nitrogen is added with overpressure into the foam generator
• The nitrogen expands when it exits the generator, creating robust high expansion foam
• The high expansion foam bubbles are filled with > 99% nitrogen

Anoxia: Single foam generator systems
• In practice, one Anoxia foam generator creates a volume of up to 750 liter of high expansion foam per minute
• This volume is more than sufficient to fill a wheelie-bin container within 30 seconds
• The most common container volumes are: M size - 240 liter; L size - 340 liter; and XL size - 370 liter
• The choice of the volume of the container depends of the size of the animal and/or the number of animals that need to be stunned/killed
• A lid with a chiffon that seals the container
• As soon as the foam exits the chiffon, the gas supply is stopped and the chiffon is closed. The nitrogen gas concentration in the container remains at 99%
