New oxygen fuel gas rule, effective May 1, now applies to general industry and construction employers
Oregon OSHA's new oxygen-fuel gas welding and cutting rule - 437-002-2253 – now applies to general industry and construction employers. The rule, which went into effect May 1, replaces a number of general industry rules as well as 1926.350, Gas Welding and Cutting in construction.
437-002-2253's key requirements:
- Covers only the following oxygen-fuel gas activities: welding, cutting, brazing, soldering, and flame coating.
- Requires employees to be trained by a competent person before doing oxygen-fuel gas activities.
- Allows only oxygen cylinders to be cracked.
- Requires cylinders to be drop tested and explains how to perform a drop test. The drop test must be performed before each shift when the equipment is used. Those that fail a drop test must be leak tested.
- Requires cylinders transported in "enclosed" vehicles to be leak checked.
- States that cylinder valves do not need to be closed during the lunch hour.
- States that flashback arrestors and reverse flow check valves are not necessary unless the manufacturer requires them.
- Requires stored cylinders and cylinders transported in enclosed vehicles not to be exposed to temperatures of 125 degrees F or more
- Requires stored cylinders to be separated from fuel gases or other combustibles by a minimum of 20 feet or a noncombustible barrier.
- Requires that separation barriers covered by 437-002-2253 must:
- Have a fire-resistance rating of 30 minutes or longer
- Be at least 5 feet high and extend at least 18 inches vertically above the tallest cylinder
- Extend a minimum of 18 inches horizontally beyond the sides of the cylinders
437-002-2253 does not require noncombustible separation barriers built before May 1, 2015, to have 18-inch extensions.
