Escape chamber
Escape chambers are mobile shelters into which people can retreat in a contaminated environment, for example due to the risk of fire. They are often used in mining and tunnel construction and are partly mandatory (BS6164, EN 16191, Australian Guideline). They usually consist of a gas-tight container. The interior is equipped with life support systems. This includes systems for exchanging or processing breathing air as well as air conditioning. In addition, there is often a system for maintaining a slight overpressure in the room in order to avoid contamination of the interior.
An escape chamber usually offers space for 15 to 24 people. The deployment time can range from 3 to 36 hours, depending on the applicable standards and security concept.
