The safeguard must prevent hands, arms, and any other part of a worker’s body from making contact with dangerous moving parts. A good safeguarding system eliminates the possibility of the operator or another worker placing parts of their bodies near hazardous moving parts.

Q. Are licensed electricians available for electrical work?

Ans. Electricians are licensed and specialized tradesman who install and maintain electrical systems. They are responsible for a wide-range of tasks which may include installing lights in buildings or troubleshooting problems due to faulty wiring.

Unlike many other jobs in construction, electricians require extensive training and an apprenticeship before they can get licensed and practice without supervision.  Sub-rule (1) of rule 45 electricity rules 1956

Q.Whether area classification for electrical equipment has been carried out?

Ans. Electrical area classification (EAC) is the process of determining the existence and extent of hazardous locations in a facility containing any of those substances. The result of the process is usually called the EAC of the facility. As per IS 5571.

Q. Do the electrical fittings conform to area classification for electrical equipment?

Ans. Electrical equipment that has been classified as safe for use in hazardous areas, which are often referred to as areas Nonequipment may emit small sparks or reach high temperatures that can ignite in hazardous areas, causing explosions or fires. As perIS 5571.

Q. Is a ground fault current interrupter system (ELCB) in use?

Ans. Earth leakage protective device the supply of Energy to every electrical installation other than low voltage installation below 5 KW and those low voltage installations which

do not attract provisions of section 30 of the Indian Electricity Act, 1910, shall be controlled by an earth leakage protective device so as to disconnect the supply instantly on the occurrence of earth fault or leakage of current.

Provided that the above shall not apply to overhead supply lines having protective devices which are effectively bonded to the neutral of supply transformers and conforming to rule 91 of 1,E. Rules, 1956.

Q. Are all connections made by using appropriate plugs, receptacles, or enclosures?

Ans. When connecting large portable equipment to an electrical system, many users opt for unsafe installations that can potentially damage equipment. Receptacles connected to circuits having different voltages, frequencies, or types of current (ac or dc) on the same premises shall be of such design that the attachment plugs used on these circuits are not interchangeable. Enclosures are free from probable contact with the ground, grounded metal, metal laths, or other conductive materials, and Enclosures are guarded against employee contact.

To avoid incident and accident, you should use the proper plug which has three pins which are third pin earth. Also, you should use plugs with receptacles and enclosures which can cause fire or no damage in the electrical circuit. 1910.304 OSHA Standard

Q. Are there any make shift connection bare wires or damaged cables?

Ans. Every flexible cable attached to a portable or transportable machine shall be examined periodically by the person authorized to operate the machine, and if such cable is used underground, it shall be examined at least once in each shift by such person. If such cable is found to be damaged or defective, it shall forthwith be replaced by a cable in good condition. Indian Electricity Rule, 1956.

Q. Is there a system of ensuring periodical inspection of hand tools, extension boards used for electrical work?

Ans. Employees must supervision and annual inspections required by the standard indicate that they are not complying with the required safety-related work practices; new technology or equipment, or revised procedures, require the use of safety-related work practices that differ from their usual safety practices; and they use safety-related work practices that are different than their usual safety practices while performing job duties. As per electrical work 1910.137(a) OSHA

Q. Do the employees use proper types of PPE during the working on the live line?

Ans. Every person who is working on an electric supply line or apparatus or both shall be provided with personal protective equipment (PPE), tools, and devices such as rubber gloves (IS 4770) and rubber safety footwear (IS 15298) suitable for working area.

Q. Is the separate work permit issued for working on high voltage line?

Ans. A voltage between 650 volts and 33,000 volts is under high voltage. Permits to work are required whenever there is a significant risk to safety and health during an operation, and where precise preparation of the site or plant and clear, unambiguous communications of procedures is needed to control the risk

Q. Whether the process(s) and equipment that generate and accumulate static charge have been identified?

Ans Static electricity is an imbalance of electric charges within or on the surface of a material. A static electric charge can be created whenever two surfaces contact and when two materials are in contact, electrons may move from one material to the This process is integral to the workings of the Van de Graaff generator.

Q. Whether all such equipment including pipelines for flammable materials is properly bonded and earthed?

Ans. Metallic services like water pipe, gas pipe, etc. shall not be used as earth electrode or earth fault current return path. However, these shall be bonded to the equipotential

bonding system at the origin of installation and wherever necessary to reduce touch potential.

Alternating current systems which are connected with earth as aforesaid shall be electrically interconnected: Provided that each connection with earth is bonded to the metal sheathing and metallic armouring, if any, of the electric supply lines concerned. Section 41 CEA Regulation 2010.

Q. Whether earth pit resistance is measured and the record maintained?

Ans System earthing is essential to the proper operation of the system, whereas equipment earthing concerns the safety of personnel and plant. A key function of equipment earthing is to provide a controlled method to prevent the buildup of static electricity, thus reducing the risk of electrical discharge in potentially hazardous environments. Generally, resistance to earth of less than 106 Ω.m will ensure the safe dissipation of static electricity in all situations. Section 48, CEA Regulation 2010.

Q.Whether lightning arrestor has been installed and is adequate?

Ans. The highly conductive copper and aluminum materials used in a lightning arrestor system provide a low resistance path to safely ground lightning’s dangerous electricity. These materials and components are UL-listed and specially manufactured for lightning protection. When a lightning arrestor grounding network is in place, the strike is intercepted and directed to the ground without impact on the structure, occupants, or contents. A lightning protection system that meets national safety standards of NFPA 780 and IEC 62305  includes strike termination devices, down conductors, bonding, and surge protection. Failure to follow the Standards or use of non-listed materials or methods can result in inadequate protection.
