When our method is used for ending animals’ life, a system is filled with nitrogen captured in high expansion foam, when the bubbles in the foam break, the oxygen level in the air go in a swift instant from 21% to under 2%.
Air consists of 78% nitrogen and 21% oxygen. Animals have no receptors that make them react to the changed levels of nitrogen in the air from 78% to 98% nitrogen. They lose their posture and consciousness within 10-20 seconds, unaware of what is happening. The significant advantage of this procedure is that it is very quick, without any additional stress and pain.
