Consolidated Requirements

4.2.2 Cryogenic liquid containers - In addition to the requirements

CGA P-1, 4.7.2

listed above for other compressed gases, cryogenic liquids

must be moved by use of a four-wheeled hand truck

designed to move cryogenic liquefied gas containers with a

capacity greater than 20 gal (76L). Hand trucks must be

kept in good operating condition.

4.2.3 Acetylene - The in-plant transfer of acetylene in cylinders

CGA G-1

shall be in accordance with CGA G-1.

4.2.3.1 Acetylene shall be called by its proper name,

CGA G-1, 5.1.1

"Acetylene." Acetylene shall not be referred to

merely by the word "Gas."

4.2.3.2 When acetylene cylinders are moved, they should*

CGA G-1, 5.2.1

not be subjected to abnormal mechanical shocks

that might damage the cylinders, the valves, or the

fusible pressure relief devices. Care shall be

exercised to ensure that acetylene cylinders are not

dropped or permitted to strike each other violently.

4.2.3.3 Acetylene cylinders should* not be dropped while

CGA G-1, 5.2.2

being unloaded or loaded from a truck or dock.

[NOTE: Trucks with elevator tailgates provide a

very good means of unloading or loading acetylene

cylinders safely.]

4.2.3.4 When transporting acetylene cylinders by crane or

CGA G-1, 5.2.3

derrick, lifting magnets, slings, ropes or chains, or

any other device in which the cylinders themselves

form a part of the carrier should* never be used for

hoisting acetylene cylinders. When transporting

acetylene cylinders by crane, a platform, cage or

ladle should* be if will protect the cylinders from

damage and will keep them from falling out.

4.2.3.5 A positive method such as chaining should* be

CGA G-1, 5.2.4

used in securing acetylene cylinders that are

standing upright. During movement, acetylene

cylinders shall not be transported when lying

horizontally with the valves unprotected in a

position that would allow the valves to collide with

stationary objects.

4.2.3.6 Acetylene cylinders should* never be dragged from

CGA G-1, 5.2.4

place to place.
