Self-Contained Self-Rescuer (SCSR) for Underground Mining - DEZEGA CARBO-70

The DEZEGA CARBO-70  is a portable waist-worn self-contained self-rescuer (SCSR) that is used for escape from irrespirable atmospheres, particularly over long-haul routes.

This self-rescuer grants 70 minutes of comfortable breathing conditions, in accordance with GOST standards. Housed in a compact and ergonomic unit, the starter is activated as soon as the device is opened, immediately dispensing oxygen.

The DEZEGA CARBO-70 SCSR is a closed-circuit breathing apparatus, ensuring the user does not inhale outside gases after donning. The device provides the user with both an oxygen source and a carbon dioxide neutraliser (scrubber).

Chemically bound oxygen reacts with the carbon dioxide exhaled by the user; ultimately absorbing the CO2 and and allowing breathable air to circulate within the device.

The CARBO-70 self-contained self-rescuer features an automatic starter, in which oxygen generation begins automatically when the device is opened.

  • GOST certified
  • 70 minute minimum duration
  • Compact design at 2.8kg weight
  • Automatic starter device, activated as soon as device is opened
  • KO2 (chemically bound oxygen) source
  • Rugged construction with abrasion resistant case
  • Colour-based moisture indication
  • Ergonomic design - wear either on the belt or shoulder
  • Less weight felt due to unique gravity point

Designed specifically for underground mining, the CARBO-70 SCSR is housed in an anti-deformation, ruggedised casing. This ensures the life-saving equipment is kept free from damage, particularly in mines with highly abrasive surfaces and narrow passageways.

The moisture indicator is a transparent capsule with hydrophobic material, installed in the self-rescuer casing on the top of the unit.

Should the indicator change colour from blue to pink, this is a sign that moisture has infiltrated the capsule; resulting in a risk of case leakage and untimely cartridge activation. The self-rescuer must then be checked with a DEZEGA testing unit.

Behaviour in an emergency is difficult to predict. Human instincts are sometimes counter-intuitive. The best way to maximise chance of survival is training personnel in how to don and breathe in a self-contained self-rescuer in order to develop learned behaviour.

The DEZEGA training SCSR allows personnel to practice the donning procedure and experience breathing conditions until the process becomes second nature. This greatly reduces the risk of failure to don an SCSR and efficiently escaping from irrespirable environments.

  • Exactly replicates the particularities of donning the DEZEGA CARBO-70
  • Reusable case
  • Replaceable breathing hoses and mouthpieces are available, allowing multiple personnel to train on the same unit

Chemical oxygen is moisture-sensitive. Although all DEZEGA SCSR cases are leak-proof, improper storage and wear might case undetectable leaks. A moisture indicator will react to the slightest degree of leakage.

The SCSR testing device can be utilised to ensure that the case has no critical damage and the unit is in working condition. This device should be used for regular inspections, as well as in the case of a moisture indicator turning white or pink.

Sites can purchase their own SCSR testing device, or units can be tested and serviced by MineARC Systems' team of technical experts.
