Hazards And
precautions

3. Electric Hazards
■ Improper grounding
■ Exposed electrical parts
■ Loose or improper connection
■ Improper use of extension cord and appliances
equipments.
■ Inadequate wiring
■ Damaged insulation
■ Pinched or pierced wire insulation.
■ Inactive circuit breakers.
■ Overloaded circuits
■ Damaged tools and equipment
■ Wet conditions
■ Contact with overhead power lines.
■ There are many more that are
not recorded here

4. What are the side effects Of Electricity In
Environment/Plants and Machineries
■ Arc Flash/Blast: Emits heat and intense light that causes
burns.
■ Fire: Occurs with faulty outlets, old wiring, cords, and
switches.
■ Explosions: When electricity ignites explosive material in
the air.

5. What are side effects of Electricity in Human
Effects on the human body
■ loss of consciousness
■ muscle spasms
■ numbness or tingling
■ breathing problems
■ headache
■ problems with vision or hearing
■ burns
■ seizures
■ irregular heartbeat
■ Parmanent Disability/ partial permanent dis ability.
■ Loose of Life.

6. Effects on human body

7. General safety measures of electricity hazards
■ Put an effective lockout/tagout on live, energized circuits
■ Wear protective eyewear and appropriate gloves while
working
■ Keep the work area neat and tidy by removing all debris
daily
■ Avoid mishaps by installation and maintenance.

8. Adequate Training to understand electric Hazards
■ Be sure to provide thorough, up-to-date training
and supervisionfor all of your employees,
especially those working directly with electricity.

■ Flammable or Ignitable Equipment
■ Overhead Electrical Lines
■ Physical Barriers
■ Insulated Tools & Equipment
■ Electrical Testing.

10. Electric Safety Precautions During Hot works
■ Safety During Welding
■ Make sure all cables are in good condition
■ No bare insulation or frayed wires .
■ Protect cables from vehicular traffic or other hazards
so the cables are not damaged, cut, or pinched.
■ Make sure that the electrode holder is insulated. Crack
free.
■ Do not replace the welding electrode with a bare hand,
or with a wet welding glove.
■ Always keep the hands and the body dry during a
welding operation.
■ Avoid standing in water, on wet surfaces, or working
with wet hands or wearing sweaty garments.
■ Do not dip energized (hot) electrode holders in water.

11. Electric Safety Precautions During Hot works
■ Avoid direct contact with the live parts of
welding equipment and the workpiece.
■ Ground the work or metal to be welded to a
good electrical ground.
■ Always insulate yourself from the work and
ground.
■ Wear proper protective equipment, such as
rubber boots and rubber pads,
■ if performing arc welding in wet or high
humidity conditions. Wear rubber gloves under
the welding gloves.
■ If the welding operation must be done on steel
or other conductive material, use an insulating
mat under the operator.

12. Electric Safety Precaution duringHot Works.
■ Place the welding transformer in the close
vicinity.
■ In case of need or accident, the transformer can
be switched off quickly to cut off the power
source.
■ Turn off the welding transformer during breaks
or not in use.
■ Detach the remaining welding electrode on the
electrodeholder before leaving the welding
area.
■ Do not hold or move the welding electrode
holder and the welding return cable
simultaneously .

13. Temporary Electrification precautions.
■ Protect cables and cords from damage
■ Damage can be caused by:
– sharp edges and sharp objects
– shoes, boots or other footwear
– doors
– moving vehicles and mobile plant
– other mechanical forces
– water, oil and other liquids
– grease
– heat.
■ Arrange leads and cordsso that people won’t trip on them.
■ Avoid running leads acrossaisles or passages.
■ Raise leads up rather than running them acrossthe ground.
Raised leads and plugs should be easy for workersto reach
without a ladder.
■ Remove strain on plugs by using insulated supports.

14. Environmental Hazards for temporary
electrification
■ o Electrical equipment protectedfromweather
■ o Electrical equipment protectedfromother
harm (eg dust, water,chemicals, steam,UV rays)
■ o Power tool users able to workunder cover
during rain
■ o Battery chargers used in dry and dust-free
environments

15. Onsite Fire Extinguishers
■ Be sure to provide the correcttype of fire
extinguishers onsite .
■ So that electricrelatedfire can be
extinguished easily.
