Mine rescue equipment

K02 is used in equipment for patients requiring supplemental oxygen, in mine rescue equipment, and in the space program. The Russian Space Agency has successfully used K02 in spacesuits and in the Soyuz spacecraft.

Emergency preparedness must include equipment and supplies that will adequately protect personnel in any foreseeable emergency. It must also include research by the purchasing department to determine availabihty of emergency suppHes. Mine rescue equipment should be state of the art and should be well maintained. Telephone service must include one phone system that has an emergency power supply to enable use should electrical power fail. 

Full-face masks of class 3 are designed for use by emergency teams, fire fighters, or rescue teams in mining operations. Class 2 masks are by far the most common full-face masks in use. In comparison to class 3 masks they possess a decreased resistance, especially against heat radiation. Because class 1 full-face masks offer significantly reduced protective properties, they are not allowed to be equipped with coimectors for round or central screw threads or screw threads of type M 45 X 3. FuU-face masks are permitted for use in combination with external air supply as weU as with particle or gas filters. All use areas for class 1 to 3 full masks are listed in Table 6.20.
