OXYGEN CYLINDERS

These cylinders are made of steel and are usually painted black. They range in size from less than 1m3. To over 8 cubic m and contain compressed Oxygen at pressures that can be as high as 15 Mpa. All cylinders have valves. If Oxygen comes into contact with oil or grease, it will burst into flame. Never use oil or grease on Oxygen cylinder valves or regulators. Make sure hands and gloves are free of oil and grease before handling cylinders. Crack open the cylinder valve then close it before installing the regulator to clear the valve of any dirt. With the regulator installed, always crack the cylinder valve open first, then open it fully. This will lessen the chance of recompression which is caused by high cylinder pressure entering the regulator, heating up and damaging the regulator.
