Abstract: A new and improved gas cylinder safety cover for protecting the valve, gauge, and regulator assembly of pressurized cylinders, such as in oxyacetylene torch sets, from damage due to a fall or dropped object and additionally protecting nearby people from flying metal fragments that may be propelled by the explosive force resulting from such damage. The gas cylinder safety cover comprises a rigid shield releasably attachable to a standard compressed gas cylinder. The shield has perforated metal sides wherethrough the gas cylinder gauges may be viewed, and a fixed metal top. The shield further has a metal bottom plate hingedly connected thereto whereby the valve, gauge, and regulator assembly is exposed when the shield is hinged back open or enclosed when the shield is hinged forward closed. The new gas cylinder safety cover further includes a latch to secure the shield in the closed position and a bracket to releasably secure the shield to the gas cylinder body.
