K-SB30 ASTTAR Emergency evacuation self-rescuer

The use of a self-rescuer such as the ASTTAR is highly recommended, and even mandatory, in certain working environments such as tunnels, mines and sanitation. It is an integral part of CATEC training (Certificate of Ability to Work in Confined Spaces). It is in fact a self-contained closed-circuit breathing apparatus, which means that the air exhaled into a bag (called a "lung") is filtered and regenerated to produce oxygen. 

The CATEC training

The majority of accidents, often serious or even lethal, which occur during operations in these environments are linked to an oxygen-deficient atmosphere, the presence of toxic gases or vapours, or an explosion or fire.

The CATEC® system meets the desire of operators in the water and wastewater treatment sector to create a common skills base incorporating best practice in risk prevention when working in confined spaces. 

Fields of application of the self-contained closed-circuit breathing apparatus

• Water treatment & sanitation
• Underground mining
• Public works (tunnels)
• Chemical industry
• Maritime sector

Technical specifications of the ASTTAR self-rescuer

• Oxygen delivery method: Exhaled air in the respiratory bag (low in oxygen) is chemically regenerated with potassium peroxide (KO2). The carbon dioxide (CO2) also contained in the exhaled air is trapped and stored. 

• Operating time (emergency evacuation): 30 minutes
• Operating time (waiting, seated position): 90 minutes 
• Set-up time: Less than 10 seconds 

• Weight: 2.2 kg 
• Dimensions: 202 x 119 x 191 mm 

• Can be repackaged after use: NO

• Inhalation temperature: ≤ 50°C in accordance with DIN EN 13794:2002 (Annex A)
• Maximum temperature of KO2 during use: 200°C

• Equipment lifetime: 
  - Use: 5 years
  - Storage: 10 years
