Workplace accidents not only lead to devastating injuries to workers but also costly fines, shutdown, and equipment damage impacting the finances and productivity of the plant. In this article, we will provide a checklist to ensure safe bolting services are practiced everywhere.
First things first, every employee handling torque wrenches should be trained to operate the tool safely. Hydraulic torque wrenches being one of the most injury-prone tools needs to be handled appropriately to avoid broken hands or fingers. An untrained operator can damage his eyes and exposed parts of the skin from the toxic oil of the hydraulic torque wrenches.
Here is a checklist that you should follow before conducting a bolting job.
1. Inspect the worksite
It is important to ensure that the worksite is obstruction-free that could pose danger to the operator. The floor should be free of debris that could interfere with the hydraulic flow of hoses. Also, to lower the possibility of other workers getting injured, ensure that only the worker operating the hydraulic torque wrench should be close to the tool.
2. Employee Safety Gear
Workers should dress appropriately to avoid clothing getting caught on the torque wrench. They need to ensure that all clothing is tucked in and gloves are worn to protect the skin. Workers must refrain from wearing any jewelry. Also, safety googles or glasses need to be worn at all times.
3. Inspecting the Torque Wrench
All torque wrenches must be inspected before an operation to check for any malfunctions. If any found, they need to be repaired before an operation. Additionally, one must check the hoses and sockets for any wear offs. Evaluate the sockets to ensure that you are using the right size for the nuts that it will be placed on the job. Replace the damaged parts with components compatible with the torque wrench. Also, ensure all parts are lubricated for smooth operation.
4. Remove air from a new tool
If a hydraulic torque wrench is being used for the first time, it is likely to have air in the system. To remove the air, connect the hydraulic pump value with the hose set while connecting the couplers to the other end of the hose. Cycle the valve with a remote-control pendant and pump it several times to vent air off the tool. Then, connect the hose set to the torque wrenches to continue venting out the air from the tool.
5. Ensure the torque wrenches are calibrated
A torque wrench should be calibrated every time it is dropped and every 6 months if frequently used. A calibrated tool prevents tool damage and reduces the risks of injuries and tool damage.
6. Handle tools properly
Position yourself away from pinch points. Ensure to operate with reaction arm and position the torque wrench in the correct position i.e. without tilting.
7. Torque wrench or nut splitter
One can use special liquids and sprays to loosen nuts. For cases where nuts are rusted or frozen, use a nut splitter rather than using a torque wrench.
8. Refer the torque chart
Determine the required torque pressure by reviewing the torque chart when tightening or loosening the nut. This will ensure that you do not exceed the pump pressure required and remove the hydraulic torque wrench once the desired output is achieved.
