Moving Cylinders and Containers

Cylinders and containers must always be moved carefully. Mishandling that results in a damaged valve or ruptured cylinder can expose personnel to the hazards associated with these gases. In addition, most gas cylinders are heavy and bulky. A cylinder striking someone or pinching a finger, toe, or other extremity is a common cause of injury. For these reasons, all cylinder handlers must always wear certain minimum personal protective equipment prescribed by OSHA:

• Gloves to protect the hands against common pinching injuries.
• Safety glasses to protect the eyes against injuries associated with pressure release.
• Safety shoes with metatarsal supports to protect against foot injuries from falling cylinders.
• Before moving a cylinder to the storage area or point of use or before returning the cylinder to the supplier, ensure the following:
  • The outlet valve is fully closed.
  • The outlet valve dust plug or pressure cap is on tight for cylinders equipped with these protection devices.
  • The valve protection cap is properly secured in place on cylinders with neck threads.

Note: Valve caps must always be in place while moving or transporting cylinders or when they are in storage.

While moving full or empty cylinders:

• Always use carts or hand trucks designed for this purpose.
• Never drop cylinders or allow them to strike each other violently.
• Never lift cylinders by the cap or with a lifting magnet.
• After moving a cylinder to its point of use, secure the cylinder in place. Use cylinder stands, clamps, or other securing devices recommended by your supplier.

Opening and Closing Valves

Observing a few simple rules when opening and closing valves can prevent damage to valves and equipment and add years of useful service life to the valves. The proper way to open any cylinder valve is to first crack the valve, then open it slowly by turning the handle or stem counterclockwise. This allows equipment to gradually adjust to full pressure. Stop turning as soon as there is any resistance. Turning the valve handle or stem too far in the open position can jam the stem, causing damage and leaks and preventing later closure. Likewise, overtightening when closing a valve can damage or permanently distort the seat and result in leakage.

Note: Never open a cylinder valve that is not connected to a pressure regulating device.
