Safety Notes

  • Common compressed air working pressures are approximately 6 – 8 Bar. Air forced through the skin into body tissue can cause an air embolism. This is a condition where air bubbles are introduced into the blood stream, which can be fatal if it reaches the heart, lungs, or brain. Never place hands or body directly in the path at either the warm or cold end discharge points of THE COOL TUBE® MKII.
  • Handle the compressed air supply with caution. Use safety clips at all compressed air connection points.
  • Ensure PPE as below is worn when handling or working around THE COOL TUBE® MKII.
  • Hearing Protection must be worn whilst working near or around THE COOL TUBE® MKII.
  • Safety Glasses must be worn whilst working near or around THE COOL TUBE® MKII. Do not look straight into the cold or warm discharge air streams.
  • Safety Gloves recommended when handling. Handle with care during or after use with reduced cold and elevated warm surface temperatures to be expected.
  • An in-line course Y strainer recommended to be installed to THE COOL TUBE® MKII at the compressed air inlet or close as practicable in the supply line.
  • A 51mm / 2″ warm air extension discharge hose to be used for maximum dBA reduction and directing warm discharge air from the area to be cooled. Hose to meet site standards for FRAS rating as required for Underground Coal Mines and to be able to withstand temperatures as high as +80° C and as low as -10° C depending on the model and application used.
  • Ensure appropriate filtration of the compressed air supply is used when using as a cooling device for concealed, confined and or enclosed spaces as a breathable air supply. Always know the quality of the air being supplied and what containments are within. Use filtration and or purification as required. Site and National Standards define the minimum requirements.
  • Ensure THE COOL TUBE® MKII is mounted securely and the use of safety tethers where required.
  • Ensure THE COOL TUBE® MKII is appropriately demarcated when mounted in a location that it can be interacted with by other persons. IE – walked into when low hanging.
  • If excessive water content is in the compressed air supply and THE COOL TUBE® MKII experiences internal “icing”, ensure control measures are taken to reduce the excessive water in the compressed air supply by means of air / water separators and or air dryers used at the air compressors. In the event, ensure that the cold air stream is contained or directed in a way that will not allow any ice to be projected at persons either directly or indirectly.
  • Never tamper, modify or use THE COOL TUBE® MKII as not intended. Any signs of damage, modification or tampering to THE COOL TUBE® MKII, contact Cool Mine Pty Ltd for repair or discard the unit as not fit for service.

Magnet Safety Warning


  • Magnets must be handled with care. They are often much more powerful than most people expect.
  • The correct safety equipment & PPE should be worn, especially when dealing with larger magnets. (Gloves, glasses) Magnets, especially large neodyminium magnets, often snap together or to near metal objects. Be careful of catching fingers and potential pinch points.
  • Magnets should be kept away from credit cards, computer hard drives, watches, TV’s electronic devices & objects.
  • Place the magnet onto a surface slowly & carefully. Do not allow the magnet to snap or smash onto the parent metal or it could damage either item.
  • High temperatures (+100° C.) can demagnetise Rare Earth / neodyminium magnets.
  • Storage with different types of magnets can demagnetise them.
  • People with pacemakers MUST avoid magnets.
  • Keep magnets out of the reach of children.
