10	Scaffolding erection or dismantle work should be supervised by a qualified and experienced scaffolding supervisor or Civil Engineer.
II	During Scaffolding Erection:
11	Load Chart for Light, Medium and Heavy Duty Scaffold
	Type of Duty	Light Duty kg/m2		Medium Duty kg/m2		Heavy Duty kg/m2
	Maximum Safe Working Load (SWL)	75	150	175	225	250	300	450

	Maximum bay width (its based on jalley width but maximum permissible limit is 1.25 meter).	1.25 meter
12	The Sole plate minimum 300 x 300 x 6 mm thickness MS plate shall be used at all uneven area to support base plate. The Square Base plate minimum 150 x 150 x 6mm thickness shall be used to support all vertical pipes of Scaffolds.
13	Bay length is varied as per requirement of scaffoldings, for medium duty scaffolding following to be followed, maximum permissible limit of bay length is 2 meter and Maximum permissible bay width is 1.25 meter. Maximum 2.2-meter distance allowed ledger to ledger.
14	Plump level to be checked to base of scaffolding and all required elevations.
15	Kicker lift to be provided at height of 150 mm from the ground.
16	Minimum Platform width is 600 mm. Working platform should be without any gab and guarded completely. Don’t keep loose materials and scraps on working platform.
17	Guard railings to be fixed as following on scaffolding; Toe board to fix at 150 mm, Mid railing to fix at 550 mm, Top railing to fix at 1050 mm but not to exceed 1200 mm.
18	For securing the ladder should be provided with tie rods at top and bottom rungs. Ladders to be fixed at 75 degree and landing platform shall be provided to each 9 meters. Don’t carry any materials in hand while ascending and descending on scaffolding ladder.
19	Ladder side rails extended up to 1 meter from landing platform.
20	Cross bracing must be provided to all four sides of scaffolding but not required on stairs and access areas.
21	Wall / structure-based scaffolding shall be secured between structure and scaffolding at least every 8 meters of length and 6 meters of height.
22	The members of scaffolds shall overhang not less than 150 mm on either ends but not more than 300 mm. They shall be tight both ends by couplers.
23	Minimum overlap of vertical members (standards) and/ or horizontal members (Ledger) shall be 600mm with at least two couplers.
24	Don’t throw any materials directly to the ground, use a lift pulley to lowering the materials. The scaffolding should always be removed from the top to bottom, and the ladder and standards must be removed last.
25	Scaffolding should be able to bear more than four times the weight of workers and materials.
26	Once the scaffolding erected must be checked in every week.
27	Height of individual scaffold not exceed 3 times of bay width.
28	Safety belt should be used properly when ascending and descending on ladders at scaffolding or use Rope grape vertical fall arrestor. Safety helmet must be used with chin strap.
29	During working on scaffolding, always ensure the safety belt must anchoring with lifeline or to anchoring with strong and fixed horizontal member of the platform. The lifeline at least 12 mm wire rope or 18 mm polyamide rope. The safety Belt must confirm IS 3521.
30	Safety net shall be tied as close as possible to the working platform but not allowing more than 3 meters below the platform. The safety net shall extend out at least 2.5 meters from the side of the open edge. It’s shall be combination of fall protection of man and material from height. The safety net must confirm IS 11057.
31	Modern fall arresting device may be used depending on the requirement, i.e., Modern fall arresting devices are self-retractable fall arrester, vertical rope grape fall arrester and fall protection grip descender.
32	Shall we use tool holders, wrist tool holder, tool pocket etc. to avoid the hand tools falling from height.
33	Minimum distance required between structure / scaffolding and overhead electrical lines shall be maintained as given below; For low and medium voltage lines Up to 11 KV- 5.8 meters. For high voltage lines above 11 KV – 6.1 meters.
34	Avoid lifting of long objects such as ladder, pipes and iron rods near overhead power lines.
35	If any machine is operated electrically on scaffolding, the supply must be taken through 30 mA RCCB / ELCB only. Machine and other electrical equipments shall be earthed properly.
36	Earthing Wire should not be connected to scaffolding for any reason.
37	When working on scaffolding make sure there are no sharp rods and no sharp objects on the ground. Also make sure that no harmful chemicals and flammable substances are stored underneath.
38	Upon completion of the work, Scaffolding Height Work Permit should be returned to the concerned officer.

1. To be Ensured the entire work crew is Wearing of Suitable Personal Protective Equipment's.

2. Check the Slings and Chains. Ensure that the rigging angle is Correct.

3. Make Sure the load is properly secured and inform to the Crane Operator, Weight of the load.

4. Make Sure the Lifting gears such as hooks, slings and shackles are well maintained and in good working condition.

5. Make Sure the load is stable, balanced properly and secured before any lifting operation.

6. Make sure all loose materials are placed in a proper receptacle or container or tied to prevent that materials may falling during the lifting operation.

7. Immediately report to the Lifting Supervisor, if any defective or faulty lifting gears are identified.

8. Place adequate paddings on the sharp edges of the load to prevent the sling from damage.

9. Check the correct use of Choker hitches with D-shackles. Ensure the D-shackle is Positioned correctly.

10. Ensure the correct center balance of the D-shackles, insert sufficient washers to centralize the position of the D-shackle and load. Make sure the D-shackle is not pulled down from the hook.

11. Check the correct hook-up methods before start the lifting operation. Make sure the safety latch and other lifting gears are in good condition.

12. Secured the lifting hooks are facing out and don't secure the hooks facing in side. Don't wrap a rope around the hook.

13. For long loads, use two legged sling with double wrap choker hitches.

14. Do not tie the sling from one eye blot to another, due to force, it may tilt one side.

15. Make Sure that unused extra slings are hooked up properly.

16. If the eye is bend, the load not hook up correctly.

17. When Using four legged sling, make use of links to join the crane hook to the sling eyes.

18. Use the original screw pin of the D-shackles, don't use blot or rod as a screw pin, it will bend.

19. Use Tagline (Guide Rope) with sufficient length and diameter, so that the guide rope can be easily gripped and the load stabilized.

20. Use correct method of unloading, Do not pull out the sling from underneath the load because it will damage the sling. Put the load down on the supports and then pull out the sling.
