1.  Never drop cylinders or permit them to strike each other violently. 

2.  Cylinders may be stored in the open, but in such cases, should be protected against extremes of 

weather and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the 
shade when located in areas where extreme temperatures are prevalent. 

3.  The valve protection cap should be left on each cylinder until it has been secured against a wall or 

bench, or placed in a cylinder stand, and is ready to be used. 

4.  Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a 

suitable hand-truck. 

5.  Never tamper with safety devices in valves or cylinders. 

6.  Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is 

attached to a pressurized system. 

7.  No part of cylinder should be subjected to a temperature higher than 125°F (52°C). A flame should 

never be permitted to come in contact with any part of a compressed gas cylinder. 

8.  Do not place cylinders where they may become part of an electric circuit. When electric arc welding, 

precautions must be taken to prevent striking an arc against the cylinder.
