What is Electrical Safety Training System ?

Electrical Safety Training System

This is the document about electrical safety training system during the maintenance period. Electrical safety training is very crucial for any kind of maintenance person (especially for electricians). Electrical safety training is definite by the process in which P.P.E (Personal Protection Equipment), LOTO (Log Out Tag Out) and de-energized concept, using of engineering tools in sense of the wellbeing, net and clean approach, and high degree of consciousness are exercised during the whole training phase.

Core Concept of Safety Training:

P.P.E (Personal Protective Equipment)

• Electric graded hand gloves
• Electrical helmet
• Goggles (must work in hot work)
• Electrical safety shoes
• Electric graded jacket
• Sewing Machine lead protector

LOTO (Log Out Tag Out )

• Single Pole LOTO Device
• Triple Pole LOTO Device
• Tagging Process

Electrical Tools (Properly Insulated)

• Screw driver
• Granding M/C (N/A)
• Tatal
• Hammer
• Cilie rang
• All equipment’s related rectification based works

Merits, Demerits & how to use (At a glance):

P.P.E means personal protective device. Maintenance personnel who are not concern about P.P.E, LOTO & insulated electrical tools may cause serious injury and sometimes it could be the reason of death. (Demerits)

A man who are used to about P.P.E, LOTO and insulated electrical tools, they can avoid the electrical socks, unusual hazards. (Merits)

Before using electrical tools it is too much necessary to check its necessary portions should be insulated. If LOTO device will be ignored by personnel during the maintenance work, serious problem could be occurred so, in sense of LOTO using first, we de-energize the power source (Protective Device). Secondly, Lock the protective device that any one can’t operate it. Thirdly, a Tag should be posted near the spot which understand that maintenance work is going on.

N.B.: Scheme of LOTO and PPE have been Illustrated later.

Training Perception:

• “Consciousness” this word too crucial for any maintenance purpose. So, this concept should be worshiped by any maintenance personnel.
• LOTO (Log Out Tag Out) device one of the vital concern in the field of maintenance. Be used to about it.
• Wearing electrical safety shoes to conduct electrical tasks. (Specially for sub-station room & Boiler room)
• Using double insolated hand gloves to perform any electrical maintenance based works.
• The exercise of using electrical helmet should be bothered by the maintenance personnel, especially for heavy waited maintenance works.

• Only qualified persons may perform testing work on electric circuits or equipment. Remember once again only qualified persons.
• Employees may not reach blindly into areas which may contain energize parts. So, be concern about de-energized concept.
• Do not attempt to repair electrical equipment unless you are trained, qualified and self-assured. It should be remembered by the relative personnel.
• Test instruments and equipment and all associated test leads, cables, power cords, probes, and connectors shall be visually inspected for external defects and damage before the equipment is used.

Practice Procedure:

Electrical safety training system is defined by the process in which P.P.E (Personal Protection Equipment), LOTO (Log out Tag Out) & de-energized concept, using of engineering tools in sense of wellbeing, net and clean approach, and high degree of consciousness are exercised during the training phase. Practice Procedure of Electrical safety training will be performed within ninety (90) calendar days interval on the basis of three aspects listed as follows:

Checklist Issues Regarding In the event of an electrical fire

• Do not use a Type A, water extinguisher if you know really how to use an fire extinguisher, use a CO2 and dry chemical fire extinguisher
• If you are not sure about using a extinguisher, leave the area and close the doors behind you Wait for the Fire Dept. personnel to arrive.

Personal Protective Equipment (P.P.E) Scheme

The purpose of the Personal Protective Equipment Policy (PPE) is to minimize injury to factory maintenance personnel through the proper use and care of personal protective equipment.

Considerations

• Application: What part of the body is being protected?
• Chemical Resistance: Will material maintain structural integrity and protective qualities.
• Strength: Is the material resistant to punctures, tears, and abrasions?
• Flexibility: Does PPE provide the necessary dexterity?
• Thermal Limits: Does clothing maintain the mobility and protective capacity in temperature extremes?
• Cleanable: It Can material be easily reused?
• Longevity: It Will clothing resist age?

Electrical Safety Training Tools

Electricity and electrical equipment are used on every site and home, everyone is familiar with it, but not all seems to remember that misuse of electricity/electrical equipment is dangerous. All electrical systems and equipment must be properly selected, installed, used and maintained to avoid accident.

Electrical equipment used on site, particularly power tools and other portable equipment and their leads, faces harsh condition and rough use, is likely to be damaged and become dangerous. Modern insulated tools are well protected but their leads are still exposed to damage and should be checked regularly before use.

Before The Use of Electricity and Other Electrical Tools

• Check that all plugs and cables of the hand-held electrically powered tools are in good condition, inspected and color coded by a competent person.
• Ensure that no naked wire is exposed
• The plug is in good condition, for example, the casing is not cracked and pins not bent etc.
• Ensure that there are no tape or other non-standard joints in the cable
• Be sure that the outer case of the equipment (grinder etc) is not damaged or loosed, and all screws are in place.
• Ensure that there is no overheating or signs of burn on the plug, cable or equipment.
• Check regularly to ensure that all trip-off devices are in good working condition.
• Never improvise with electrical equipment (Don’t manage)
• Don’t leave trailing electrical cable where they can be damaged or cause tripping hazards, especially on access and walkways, raise cable above head level.
• Always assume that cables, plugs, etc. are LIVE
• Always disconnect grinders before replacing discs
• Never repair electrical tools on your own, call an electrician to carry out repairs for you
• Switch off all electrical equipment when not in use
• Do not carry grinders and other electrical tools by holding on the leads
• Do not leave extension cable and plug inside water
• Protect exposed lead and welding terminals (Cover the expose terminal with plastic cover).
• Report and remove all faulty electrical equipment and tools immediately

Scheme of Electrical Safety Training System:

All employees who are required to use PPE shall receive adequate and documented training on the basis of tentative electrical hazards as an instance:

• Wearing electrical safety shoes to conduct electrical tasks. (Specially for sub-station room & Boiler room)
• Using double insolated hand gloves to perform any electrical maintenance based works.
• The exercise of using electrical helmet should be bothered by the maintenance personnel, especially for heavy waited maintenance works.
• Only authorised persons may perform testing work on electric of circuits or the equipments
• Employees may not reach blindly into areas which may contain energize parts. Be concern about de-energized concept. This is one of the precaution to use P.P.E
• All equipment and the instruments should be insulated on required parts and all associated test leads, power cords, multi plug probes, and connectors shall be visually inspected
• Personal protective equipment (PPE) must be used when required and conductivity  apparel (watches, bracelets, rings, key chains, necklaces, zippers, cloth with  , cables, power cords, probes, and connectors shall be visually inspected during electrical safety training system
