US Department of Labor's OSHA issues final rule, revises acetylene standard

WASHINGTON - The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) has revised its acetylene standard. A final rule replaces references to outdated industry standards with updated references reflecting current industry practices.

"This final rule incorporates current technology that enhances OSHA's acetylene standard for improving industry work practices and providing safer workplaces," said acting Assistant Secretary of Labor for OSHA Jordan Barab. "It exemplifies our mission of providing strong and effective regulations that protect the safety and health of working men and women."

The revised standard requires that in-plant transfer, handling, storage and use of acetylene cylinders comply with Compressed Gas Association Pamphlet G-1-2003, titled Acetylene. The revised standard also updates references for the provisions addressing piping systems, as well as acetylene generators and filling acetylene cylinders.

Acetylene is a colorless gas that can become explosive if liquefied, heated, compressed or mixed with air. It is commonly used in certain plastics and as fuel for welding and metal cutting.

Under the Occupational Safety and Health Act of 1970, OSHA's role is to promote safe and healthful working conditions for America's men and women by setting and enforcing standards, and providing training, outreach and education. For more information, visit
