Security advices for Hose OR Gas Tubing:

Use the right cooler hose for oxygen (green/black) and acetylene (red) and by no means use oxygen hose for acetylene or vice versa. Forever defend hose from being compressed on or run over. Avoid tangle and kinks. By no means leave the hose so that it can be tripped over. Hose connections shall be made through considerable fittings and clamped or otherwise securely fastened to these connections in such a way as to endure with no leakage a pressure twice as great as the maximum delivery pressure of the pressure regulators provided on the scheme.

Guard the hose from flying flickers, hot slag, hot work piece and open fire. If dust goes into hose, blow through (with oxygen, not acetylene) previous to coupling to torch or regulator. Store hose on a reel (an automobile wheel will do) when not in use. By no means permit the hose to come into contact with oil or grease; they deteriorate the rubber and comprise a hazard with oxygen.
