GENERAL INFORMATION
1.1
The purpose of safety instruction document is to establish, implement and execute a
practical and effective method for preventing accidents, injuries and property damage.
This document will help contractors and their associates to recognize, evaluate and control
hazardous activities within their areas of responsibility.
This document defines the procedure with which safety practice will be administered,
identifies responsibilities and ensures control of work area safety.
Contract agreement signed with contractors and the provisions of this document are
intended to complement each other to ensure safe working conditions.
The provisions of this document apply to IPR and associated centres/units/departments.
Throughout this document, reference to a contractor means the contractor’s company and
the associated subcontractors, consultants, vendors and suppliers. Reference to contractor’s
management means personnel responsible for managing, supervising or directing contract
activities and employees.
Non-compliance of this document is treated as non-compliance of contract agreement that
may result in warning/penalty. Willful or repeated non-compliance may result in contractor
dismissal and contract termination.
This document for contractors is a supplementary document to statutory rules, codes and
regulations having jurisdiction, and does not negate, abrogate or minimise any provisions of
these rules, codes and regulations. It is intended to supplement and enforce the individual
program of the contractor and to coordinate the overall safety effort. Contractors are
responsible for the safety and health of their employees, subcontractors, consultants,
vendors, suppliers, and visitors while in IPR and associated centres/units/departments.
Contractor’s managers and supervisors are responsible for preventing incidents or
conditions that could lead to incidents, injuries, illness or fatalities. The ultimate success of
the safety program depends on the cooperation of everyone. The contractor’s management
must ensure that safety provisions are enforced and that effective training and education
programs are employed.

6.6 Lifting/Hoisting Equipment and Erection
Accidents do happen while working overhead or due to failure or unsafe use of hoisting
equipment. As such, adequate care must be taken to prevent it. The following are some of the
precautions to ensure safety of the workmen engaged by the contractor:
6.6.1 Contractors involved in handling of any material overhead must install necessary
barricades, warning signs or take any other steps necessary to prevent others from
walking/standing beneath the load.
6.6.2 Hoisting machines, tackles including their attachments, anchorage and supports must
conform to the good mechanical construction, sound materials and adequate strength and
free from patent defect and shall be preserved in good condition.
6.6.3 All equipments like crane, chain blocks, sling, rope including all other material handling
equipments must have valid load test certificates.
6.6.4 Thorough inspection and load testing of lifting machines and tackles shall be done by a
competent person at least once every 12 months and records of such inspection and testing
shall be maintained.
6.6.5 Every crane driver or hoisting appliances operator shall be properly qualified and no
person below the age 21 years should be in charge of any hoisting machine.
6.6.6 Every hoisting machine and all gears shall be plainly marked with the safe working load.
No part of any machine or gear shall be loaded beyond the safe working load (SWL).
6.6.7 In case of IPR’s machines, the safe working load shall be notified by Engineer-in-charge.
For contractor’s machines, the contractor shall notify the safe working load to Engineerin-charge.
6.6.8 Motors, gearing transmission, electric wiring and other dangerous parts of hoisting
appliances should be provided with safe guards.
6.6.9 No cranes shall be left unattended with hanging load and on completion of work, the
boom/jib of the crane may be brought down and kept in horizontal condition.
6.6.10 No crane including hydra crane shall be allowed to move on road with suspended load.
6.7 Welding and Gas Cutting
6.7.1 Welding and gas cutting operations shall be done only by qualified and authorized persons
and as per IS specifications and Code of Practice.
6.7.2 Welding and gas cutting shall not be carried out in places where flammable or combustible
materials are kept and where there is danger of explosion due to presence of gaseous
mixtures.
6.7.3 Welding and gas cutting equipment including hoses and cables shall be
maintained in good condition.
6.7.4 Barriers shall be erected to protect other persons from harmful rays from the work.
When welding or gas cutting is in elevated positions, precautions shall be taken to prevent

sparks or hot metal falling on persons or flammable materials. Adequate ventilation
shall be provided while welding in confined space.
Suitable type of protective clothing consisting of fire resistant gauntlet gloves, leggings,
boots and aprons shall be provided to workers as protection from heat and hot metal
splashes. Welding shields with filter glasses of appropriate shade shall be worn as face
protection.
Welding and gas cutting shall not be done on drums, barrels, tanks or other containers
unless they have been emptied, cleaned thoroughly and it is made certain that no
flammable material is present.
Fire extinguisher shall be available near the location of welding operations. Prior
permission shall be obtained from safety section for working at vulnerable areas and
operating areas before flame cutting/welding is taken up.
Tarpaulin, if used should be of fire retardant.
For electric (Arc) welding the following additional safety precautions shall be taken:
 When electrical welding is undertaken near pipe lines carrying flammables, such pipe
lines shall not be used as part of earth conductor but a separate earth conductor shall be
connected to the machine directly from the job.
 Personnel contact with the electrode or other live parts of electric welding equipment shall
be avoided.
 Extreme caution shall be exercised to prevent accidental contact of electrodes with
ground.
6.7.10 The cylinders containing poisonous/toxic or inflammable / explosive gas like Oxygen,
Acetylene, Hydrogen, Ammonia, Chlorine, CO 2 etc. shall be handled safely taking due
cares. To handle / shift such cylinders a special trolley / cage meant for it must be used but
in no case it should be rolled.
6.7.11 No domestic LPG cylinder is allowed for Hot Work such as Gas Welding / Gas
Cutting.
6.7.12 A person must remain in the area for a minimum period of 30 minutes after hot work is
completed to ensure the site is safe. Welding machine shall be switched off after the
completion of work.
6.8
Grinding
6.8.1 All portable grinders shall be used only with their wheel guards in position to reduce the
danger from flying fragments should the wheel break during the use.
6.8.2 Grinding wheels of specified diameter only shall be used on a grinder- portable or pedestal in order not to exceed the prescribed peripheral speed.
6.8.3 Goggles shall be used during grinding operation.

Consider all the equipment as live before touching until they are proved to be dead.
Before attempting maintenance on electrical equipment, ensure electrical isolation &
earthing. Follow “permit to work on electrical system” procedures.
Be sure about isolation by physical verification. Check isolation tags on
feeders/breakers.
Keep electrical insulating mat/paint in front of electrical panel/ switches.
Inspect the equipment thoroughly before normalization.
Follow SIDE rule before starting maintenance work on electrical equipment. (S=Switch
off, I=Isolate, D=Discharge, E=Earthing).
Have minimum number of cable joints and insulate properly all the cable joints.
If water cooling is used, ensure that water connections are fitted correctly with no chance
of leakage onto HV system.
Supply of energy to every electrical installation, other than low voltage installation below
5 kW, shall be controlled by an earth leakage protective device so as to disconnect the
supply instantly on the occurrence of earth fault or leakage current.
Don’t work alone in and around high voltage system.
Lifting of electrical equipment as per manufacturer’s instructions.
Do not allow visitors to enter into high voltage zones without escorting by an
authorized person.
Never depend on verbal communication for isolation of electrical equipment.
Do not wear metallic ornament while working on electrical equipment.
Do not overload the power cable beyond its current carrying capacity.
Do not insert bare wires of appliances in the plug socket.
Only trained, experience and authorized personnel should carrying out maintenance,
repair, adjustment etc.
Identified tools should be used to carry out such works.
Eli Chips and debris must be swept up and properly disposed.
