Oxygen Self Rescuers

Oxygen Self Rescuers is a chemical oxygen apparatus that provides Oxygen on demand during gas outbursts, fires, after explosions, and emergency escape situations. Self Rescuers are designed to be belt or chest worn, and the larger units are usually stored in a rescue chamber for longer duration of breathing air.

Oxygen Self rescuers provide Oxygen on demand for a set period of time by generating Oxygen from a chemical known as KO2. Self Rescuer Units have a closed breathing circuit and the exhaled air of the wearer is regenerated and enriched with Oxygen. CO2 and humidity of exhaled air will react with the KO2 and in this way Oxygen is generated and CO2 is removed. The self rescuer units from MSA, Drager and Honeywell last around 30 to 60 minutes, depending on the product.
