The ASTTAR chemical oxygen self-rescuer is an emergency evacuation breathing apparatus that enables the wearer to breathe both in cases of oxygen deficiency and in the presence of dangerous toxic substances. It has an autonomy of 30 minutes for evacuation and 90 minutes in the waiting position for rescue (seated position).
Self-contained emergency evacuation device for confined spaces or heavily polluted environments
Autonomy: 30 minutes in case of emergency evacuation and 90 minutes at rest (seated position)
Chemical oxygen generation by potassium superoxide (KO2)
Set-up time under 10 seconds
Complies with DIN EN 13794 : 2002 (Annex A)
Additional information
Comme les appareils respiratoires isolants ou les systèmes à adduction d’air, L'auto-sauveteur à génération chimique d'oxygène ASTTAR fournit un air respirable totalement indépendant de l’air extérieur. Il est largement plébiscité pour les évacuations d’urgence en espaces confinés (voir formation CATEC).
The ASTTAT K-SB30 self-rescuer operates on the principle of oxygen generation by chemical reaction. It can be activated in a few seconds to supply oxygen to the wearer during evacuation from the danger zone, or while awaiting rescue.
The ASTTAR self-rescuer's chemical oxygen generation is produced by a potassium superoxide (KO2) cartridge that reacts with exhaled air. Moisture and carbon dioxide from exhaled air in the breathing bag produce a chemical reaction in the KO2, generating oxygen among other things. CO2 is fixed so that it can't be breathed in again.
