A description of the proposed changes are as follows:

Chapter 4, Subchapter 4, Article 32, Section 1740(m); and
Chapter 4, Subchapter 7, Articles 76 and 85, Sections 4649 and 4821
Use of Cylinders Associated with Welding and Cutting Operations


Section 1740. Storage and Use of Cylinders
Subsection (m)

Section 1740 contains the requirements for the storage and use of cylinders. Subsection (m) addresses requirements when leaking fuel gas cylinders are detected. Subsection (m), in part, states if a regulator attached to a cylinder valve will effectively stop a leak through the valve seat, the cylinder need not be removed from the work area.

The proposal deletes language that permits a fuel gas cylinder with a cylinder valve leak to remain in the work area when the leak can be stopped by the use of a regulator. Language is proposed to require such leaking cylinders to be taken outdoors, to an isolated area and that the supplier be notified. The proposal may require minor procedural modifications to an employer's Injury and Illness Prevention Program (IIPP) to implement instruction/training that will ensure cylinders leaking at the valve seat are removed from the work area to a safe location even if the leak can be stopped by the use of a regulator.

Section 4649. Construction and Marking of Cylinders.
Subsection (b)

Section 4649 contains the requirements for the construction and marking of cylinders. Existing subsection (b) requires that compressed gas cylinders shall be equipped with connections complying with ANSI B57.1-1965, "Compressed Gas Cylinder Valve Outlet and Inlet Connections." A proposed amendment will require that connections for compressed gas cylinders be "approved" as defined in Section 3206 of the General Industry Safety Orders. The term "approved" means conformance with applicable nationally recognized standards. Inlet and outlet connections for compressed gas cylinders are manufactured to conform to national consensus standards. Therefore, the proposed amendment will have no effect upon the regulated public.

Section 4821. Gas Systems Piping for Welding and Cutting, Materials and Design.
Subsection (c)

Subsection (c) requires copper tubing used in welding and cutting gas systems piping to be types K and L in accordance with the Standard Specification for Seamless Copper-Alloy Water Tube, ANSI/ASTM B586-1980. Board staff determined that the reference to ANSI/ASTM B586-1980 in this subsection is incorrect since the correct title of ANSI/ASTM B586-1980 is Welded Copper-Alloy Water Tube. Furthermore, types K and L piping which contain the strength and tolerance requirements for seamless copper water tube are not discussed in that standard. An amendment will correctly reference the appropriate standard, ASTM B88-1996, Seamless Copper Water Tube, which will be incorporated by reference.


American Society for Testing and Materials, ASTM B88-96, Standard Specification for Seamless Copper Water Tube.

This document is too cumbersome or impractical to publish in Title 8. Therefore it is proposed to incorporate the document by reference. Copies of this document are available for review during normal business hours at the Standards Board Office located at 1300 I Street, Suite 920, Sacramento, California.
