Comprehensive Guide: Dismantling Steel Structures and Safety Procedures

Dear All,

I need SWP for dismantling of steel structures, which includes roof sheets. Can anyone send or share the SWP or safety procedures?

Thanks,
Vijay

Dear Vijay,

Your query was not clear which type of sheet are you going to remove Polycarbonate sheets, Aluminum sheets, FRP, Galvanized sheets etc.., Are you removing the sheets from Pre Engineering building (PEB)or Something else ???? What is the height of the building???? Etccccc…,,,
Let u come with some picture will help you and give the right documents first of all demolition plan should be prepared by Registered engg not SAFETY GUYS.
Come with some exact picture will help you. Keep on touch. . .

Dear Mr. Raghu,

Thank you for your reply. If I may be precise, we are planning to remove the existing Electrostatic Precipitator (ESP). We have installed a new one, and for the retrofit work, we will be dismantling some of the major components in the existing ESP. When I mention 'Sheet,' I am referring to GI sheets used for weather enclosure. The height of the ESP stands at around 45 meters.

Regards,
Vijay

Dear Mr. Vijay,

I agree with Mr. Raghu.

You need to give some more details like size and height of the structure to be dismantled, type of roofing sheets to be dismantled, etc.

However, we have recently changed from Asbestos Sheets to Galvalume Clip-on type roofing sheets with Insulation. The top height was approximately 14.0 meters. Attached are a few photographs of the work. We used safety net while dismantling as well as during the new erection of sheets. The net was tied in such a way that EOT crane operation was possible. The work was completed without even a minor accident. Only one near miss of falling objects was reported. The shop floor activities down below were not disturbed at all.

However, here are some tips for any kind of dismantling work:

1. Start the dismantling from the top using Safety Belts, Helmets, and other required PPE's depending on specific hazards.

2. Put up a barrier so that the dust does not spread to other areas.

3. Spray water to avoid the generation of dust.

4. Shift debris immediately after the work.

5. Switch off / Take out the electrical wires and other utilities if any.

The scaffolding to be rigid. Do not use Bamboo scaffolds.

6. The platform to have fall arrest railings.

7. The workmen on the ground to use safety goggles.

8. Barricade the area so that entry to unwanted people is restricted.

9. If concrete is to be dismantled, take care if Reinforcement Steel is to be cut by Gas Cutting method.

10. Use proper anchoring points if required. It is advised to check the strength of the points where anchoring is to be done.

11. Conduct Daily Safety Toolbox Meeting.

You may add the suitable instructions depending on your specific hazard identification which is expected before the commencement of the work.

Dear Vijay,

You need to be very careful when working at 45.0 meters.

1. The scaffolds are to be used and inspected after erection. The full-body harness should be compulsory.

2. Use construction lifts to bring the removed sheets down. If these are to be lowered by rope, ensure they are lowered using the best engineering controls.

3. Issue work permits and ensure that the workmen do not have a height phobia problem.

4. Please upload some photos as working at this height is slightly uncommon. This will help young Safety Professionals visualize the type of work.
