1. Introduction
This method statement outlines the procedures and safety measures to be followed for the lifting of gas cylinders. The task involves the proper handling, transportation, and positioning of gas cylinders to ensure the safety of personnel, property, and the environment. Gas cylinders can contain various hazardous gases, and mishandling them can lead to accidents, injuries, or gas leaks, which can have serious consequences. Therefore, this method statement aims to provide clear guidelines to ensure the lifting of gas cylinders is carried out safely and efficiently.
2. Description
Gas cylinders are used to store and transport various types of compressed gases, such as oxygen, acetylene, nitrogen, argon, etc. These cylinders are typically made of steel or aluminum and are pressurized to store a large volume of gas in a compact form. The lifting of gas cylinders involves the following key steps:
3. Risk Assessment
Before starting any lifting operation, a thorough risk assessment must be conducted to identify potential hazards and risks associated with the task. This assessment should take into consideration factors such as the weight and size of the gas cylinder, the location of the lifting operation, the lifting equipment to be used, and the competency of the personnel involved.

- Safety Glass (clear)
- Leather Gloves
- Mask
- High Visibility Vest
- A toolbox talk will be carried out before starting a job daily, making sure that every individual understands their roles and responsibilities throughout the job.
- The toolbox is to be conducted in as many languages as are required to achieve this objective.
- The toolbox talk should always emphasize safety for all activities involved in completing All personnel involved in the activities should sign on a toolbox record sheet.
7. METHOD STATEMENT
Note: This method statement represents the procedure to be followed, drawings, and risk assessments to ensure the safe and professional completion of the project scope.
7.1.1. At a designated date/time our 30 Ton Mobile Crane will be mobilized to the site.
7.1.2. A necessary permit is to be obtained before set up and operation in the demarcated area.
7.1.3. New personnel arriving on site will be given a site safety induction briefing to establish a Safe System of Work, which will be in force for the duration of all activities at the site. Personnel will also be briefed on the correct use of Personal Protective Equipment (PPE).
7.1.4. The exact set-up location for the crane will be surveyed for available space, sufficient ground-bearing capabilities, underground services, and obstructions. Any underground services or obstructions in the set-up location will be noted and discussed with the client with a view to temporary protection or temporary removal/reinstatement as appropriate before crane setup.
7.1.5. The risk assessment will form the basis of the pre-task talk involving all personnel concerned with mobilizing and setting up the crane(s). Each person will be briefed on his specific tasks during mobilizing and crane set-up.
7.1.6. Once the crane will reach the site and take a position at a particular location suitable place to achieve maximum distance, acquire us working radius as per the lifting plan.
7.1.7. A helper will project 100% of the outrigger out from the crane.
7.1.8. Helpers will put a wooden crane mat below the outrigger to maintain leveling of the crane to the ground.
7.1.9. Helpers will adjust the height of the outrigger and maintain the leveling of the crane outrigger parallel to the ground.
7.1.10. Then for making the hook free, the rigger will give an appropriate signal to the operator to up the boom and for loosening down the wire rope for detaching the hook from the rope when the hook will become free from the rope, the helper will unhook it.
7.1.11. Reeveves will be made as per the required configuration.
7.1.12. Once the crane is set up and the job foremen/operator is gratified in all respects, the operator will be asked to cautiously raise the boom to get the required height. The operator will simulate the lift to check the radius and reach of the crane for any necessary adjustments, if required the job foremen will double-check in all aspects, to ensure everything is perfect.
7.1.13. These procedures for crane setting will be done if the crane has to be shifted to another location for the job as per the preferred radius mentioned by the supervisor (in charge).
7.2.1. On completion of crane setup and rigging the operator will set the boom to the required configuration as per the lifting plan.
7.2.2. Dimensional checks for the lift radius and the swing radius are to be verified.
7.2.3. The lifting tackle will be inspected for condition and the correct color code before all lifting operations.
7.2.4. Lifting tackles will be connected to the hook block as per lifting study/supervisor (in charge) instruction.
7.2.5. Weather conditions will be closely monitored before and during all lifting operations.
7.2.6. The boom tip will be positioned directly over the Centre of gravity of the gas cylinder. (Centre of gravity is given by Client)
7.2.7. The lifting tackle will be attached to the lifting points of the gas cylinder.
7.2.8. The crane(s) will lift until all the lifting slings are tight. The gas cylinder weight will be monitored using the safe load indicator (SLI) equipment and checked by the Lifting Supervisor (in charge) that it is as predicted.
7.2.9. The verticality of the hoist ropes will be checked.
7.2.10. The gas cylinder will be loosened; the item is progressively raised checking the gaps until it is slightly clear of the support. The load will be monitored using the SLI equipment and checked by the Lifting Supervisor (in charge) that it is as predicted.
7.2.11. A safety check will be carried out to ensure all lifting tackle is secured.
7.2.12. Tag lines will be fitted to the gas cylinder.
7.2.13. Confirmation to proceed with the operation will be approved by the Lifting Supervisor (in charge).
7.2.14. The crane(s) will then commence hoisting until the gas cylinder is fully clear from the support.
7.2.15. The crane(s) operator will then lift the gas cylinder to the required height and swing the boom toward the installation area (The installation area will confirm by the client).
7.2.16. The slewing area should be clear from all obstacles.
7.2.17. Once the load reaches overhead the erection point, the site supervisor (in charge) will instruct to lower the hook. The process will be progressing very slowly and it will continue until the load is completely positioned (the final position will be as per the lifting study).
7.2.18. Once the Load is completely positioned at the erection point, lifting tackles will be released from the lifting points.
7.2.19. After completion of the task, we will start the course of de-rigging and retracting the boom/outrigger.
7.2.20. The BOB crew will de-mobilize the crane to the BOB yard.
