Used by Permission

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 lo- cated 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 suit- able 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 at- tached 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, precau- tions must be taken to prevent striking an arc against the cylinder.
