is oxy -Acetylene set is allowed along with workmen( Two) for cutting activity in a Man basket.The area is at 40 m height so optimum pressure will not reach if gas cylinders are kept at ground level

Provided you keep to the SWL of the Manbasket for men and weight there should be no problem.BS7121 will help. Obviously all other controls must be in place Harnesses, Spark suppression and creating a stable work platform. Regards Alex

Thanks a lot. We have placed the following checklist in place before commencement of work. So nice of you. Regards. Tushar.

No Yes The crane is on firm footing and the crane outriggers are all the way out, down, and locked as applicable. No Yes The crane is level within 1 percent, (1 foot in 100 feet) and is on firm surface. NOTE: Stability of the footing will be verified during the full cycle of the operation test.

No Yes Special precautions have been taken to protect personnel from electrical hazards. When the crane with a manbasket is working near electrical lines or devices, the minimum working clearances shall be at least twice those for material handling operations. No Yes A manbasket use authorization has been issued dated and properly signed for the task at hand. No Yes The manbasket and rigging has been proof-tested to 125 percent of the platform rated capacity. No Yes An unoccupied trial lift loaded to at least the anticipated lift weight has been performed and hoisted to each location where work is to be performed, or to any point where employees are expected to enter or exit the platform. NOTE: The trial lift must be performed each time the crane is moved. No Yes A post trial-lift inspection of the crane has been carried out by a designated employee.
