The program changed from usage of the Draeger BG174 to the Drager BG4 self-contained breathing apparatus. Standardized competency based training programs were developed to ensure consistent delivery of information to mine rescue teams across the province.
Compared to the modern day Draeger PSS BG4 sets, and the American BioPak. which can all be completely stripped and reassembled by hand without using tools, the SEFA is less convenient to maintain. The SEFA is still in use in the mining industry in India, and up until 2006 was still being used at the Porgera Gold Mine in Papua New Guinea .
Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.
Elastomeric masks linked to backpack air tanks: self-contained breathing apparatus, worn by firefighters advancing with a firehose. There are two major application areas for SCBA: firefighting, and industrial use in confined spaces. [20] For SCBAs used in firefighting, manufacturers typically prioritize fire resistance and weight reduction over ...
The semi-closed breathing circuit used the injected gas to circulate the gas in the helmet through a scrubber, providing a very low work of breathing in comparison with most other rebreathers which used the lungs of the diver to circulate gas in the loop. The Modell 1915 bubikopf helmet was designed for use with this system. The rebreather loop ...
A Drägerman or Drägerwoman, also spelled Draegerman [1] or Draegerwoman, is a common name for a rescue worker in mines. [2]The name originates from Alexander Bernhard Dräger, a German scientist who invented the combination of a gas mask and an oxygen inhalator as a breathing apparatus for underground rescue workers.
US Navy Emergency Escape Breathing Device (EEBD) Russian submarine-escape suit including an escape rebreather.. Escape breathing apparatus are a class of self contained atmosphere supplying or air purifying breathing apparatus for use in emergencies, intended to allow the user to pass through areas without a breathable atmosphere to a place of relative safety where the ambient air is safe to ...
Draeger Ray dive/surface valve with bite grip scuba mouthpiece, non-return valves, and breathing hoses. A breathing hose or sometimes breathing tube on a rebreather is a flexible tube for breathing gas to pass through at ambient pressure. They are distinguished from the low-, intermediate-, and high-pressure hoses which may also be parts of ...
