81. What are the general precautions to be taken before and during using an ABRASIVE WHEEL? 

Precautions - Abrasive Wheel:

 Ensure the spindle speed doesn‟t exceed the maximum speed marked on the wheel.

 Ensure fit the wheel on the spindle freely.

 Tighten the spindle nut enough to hold the wheel in place without distorting the flange.

 Do not stand in front of the rotated wheel.

 Provide protective guard for a moving abrasive wheel and maintain proper alignment with the wheel.

 For any bench mounted abrasive wheel, the wheel rest should be adjusted as close as practicable to the abrasive wheel, which shall be firmly secured.

 Before mounting inspect closely for damage, perform sound-test or ring-test to ensure free from cracks/defects.

 Don‟t adjust wheel while it‟s rotating and disconnect tools when changing the wheel.

 Don‟t use expired abrasive wheel and removed damage/crack wheel and tag it “do not use”.

 Must be used eye and face protective device (goggles, face shield etc.).

 Wear the suitable respiratory protection also in case abrasive wheel generates dust.

 A sign shall be posted near all fixed abrasive wheel.

What is safety precaution to be taken prior to start & during the WORK AT HEIGHT & why it is required?

 The work is properly planned, organized. Appropriately supervised and carried out ensuring safety of workers and integrity of worksite.

 The worksite including its access as well exit is safe with necessary protection against fall from height.

 Similarly the workers to be deployed for work at height are trained and aware of potential hazards.

 PPE, appropriate fall arrest system such as Safety Harness, Safety Nets etc. shall be used to protect the person from fall.

 The personnel working at height must use appropriate & approved Full Body Safety Harness and attached to a secure anchorage.

 All the straps of safety harness shall be securely tightened to the body parts.

 The tools and equipment to be used at height must be kept properly securedto prevent its accidental fall or tripping hazard.

 The area in the vicinity of work at height should be barricaded and danger notice posted to alert the personnel.

 Man Basket: 

Workers should keep all body parts inside the man basket while it is being lifted or positioned. Workers must wear a personal fall arrest system, and Helmet with chin strap must be worn at all times. 

 Sloping Roofs: 

Employee worked in roofing activities on slope roofs with unprotected sides and edges 6 feet (1.8 meters) or more above shall be used appropriate Safety Harness, Safety Net and Guardrail or a combination of these.

82. What are the safety PRECAUTIONS to be taken while performing LIFTING OPERATION?

 The load is clear of any obstruction

 The load is securely slung (use tie ropes)

 The security of the load is to be reconfirmed once the load is raised a few inches.

 The crane is not used to drag the load or pull the slings beneath a few inches.

 No movement is allowed under the suspended load.

 Barricade the swing radius of the crane.

 Never sling different size of tubular together

 The crane hook is in central position over the load.

 All equipment must be inspected by third party and validity of inspection must be checked.

 Daily inspection sheet of cranes must be always available with crane operated.

 SWL of the crane and hook shall be marked and highlighted.

 Fire extinguisher of approved type & capacity.

 Crane hook secured prevent swinging action in transit .

 A calibrated SWL indicator &crane capacity chart prominently displayed in the cabin.

 All loose material is to be removed from the top of the load.

 Slings is protected from sharp edges by using suitable packing

 Hooks used on lifting equipment should be fitted with safety device to prevent the load or sling displacement for hook.

 Do not used wire rope slings if it is kinked, crushed, frayed or corroded.

 Slings must never shortened by tying knots in them or by wrapping round a crane hook.


83. What are the Potential HAZARDS while performing LIFTING OPERATION?

 Accidents hit or crush by hanging load.

 Falling objects

 Collapse of lifting equipment due to overload.

 Overturning of the crane.

 Failure of lifting gears such as wire ropes, hooks, shackle, eyebolts, chain etc.

84. What is Rigging & Slinging? 

Rigging and Slinging is a part of mechanical handling activity which involves lifting and shifting of heavy material through the safe use of equipment, machinery or devices such as crane, wire rope, hooks, shackles, chain pulleys etc.


85. Explain about Compress Gas Cylinders? 

Cylinders testing: 

Contractors may be required to provide proof that compresses gas cylinders have been tested in excess of their normal maximum pressure when filled. 

Cylinder connections: 

Compresses gas cylinders shell is equipped with
