Minnesota Administrative Rules

1513.0920 CONTAINER AND CYLINDER VALVES AND REGULATION EQUIPMENT.

Subpart 1.

Tampering protection.

Container and cylinder valves and pressure regulation equipment must be protected against tampering when installed for use.

Subp. 2.

Protection during transit and storage.

Container and cylinder valves shall be protected while in transit, in storage, and while being moved prior to connection to the process line, as follows:

A.

by setting them into a recess of the container; or

B.

by ventilated metal cap or collar, fastened to the container, capable of withstanding a blow from any direction equivalent to that of a 30 pound weight dropped four feet. Construction must be such that a blow will not be transmitted to the valves or other connections.

A valve on a cylinder which is enclosed in a box or crate of sufficient strength to protect the valve from damage during transit or storage need not be provided with a protective cap or collar.

Subp. 3.

Not in service.

If containers or cylinders are not connected for service, the outlet valves must be kept tightly closed and protected even though containers are considered empty. This requirement does not apply at a facility specifically designed for filling containers or cylinders.

Subp. 4.

Cylinder valve connection standards.

Cylinder valves must be in accordance with the connection standard for ammonia as contained in CGA V-1, American National, Canadian, and Compressed Gas Association Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections (ANSI/CSA/CGA V-1).
