The document discusses electrical safety and provides information about electrical hazards. It notes that current, not voltage, is what can kill and outlines basic safety rules like avoiding contact between different points in a circuit. The document also discusses effects of other electrical quantities like body resistance and the low milliamp threshold for fibrillation. Overall, it emphasizes establishing safety programs and understanding electrical hazards to work safely.

2. •Electrical professionals can make their workplace
safer by following safety regulations, establishing a
safety program, and understanding electrical
hazards.
•As being Electrical Engineers, we should all know
the basics of Electricity & the basic rules for our
safety, in Electrical field such as experimental labs.
•It is actually current that kills, not the voltage.

3. One Of The Basic Example To
Understand Electricity
Why Do Birds Sitting On An Electrical
Wire Do Not get Shock????

4. THE REASON BEHIND THIS
 The Birds on a single phase wire stand on their both
feet.
 They actually get shock in nano range so they do not
feel it.
 They are on the same potential, not completing the
path of return to the ground.

5. HAZARDS OF ELECTRICAL SHOCK
•Accidental grounding path from trees which complete
the current flow path.
•Two persons contacting different points in a circuit path
will result in electric shock to both of them.
•Path for the current to the ground through the dirt.
•High power transmission lines have high currents and
hence higher magnetic field .
•High voltage current has the ability to attract upto 18
meters or above.

6. EFFECTS OF OTHER QUANTITIES
 Body resistance is not a fixed quantity, it depends on
many conditions and hence varies.
 By research , a current of only 17 milliamps is enough
for fibrillation (Muscular twitching).
 Electrical resistance between any contacting objects
becomes smaller with increased contact area.
 Only a 12v battery is enough dangerous if it
accidentally come in contact across some other hazard.

7. Pictures Are Words

8. SAFETY RULES
 Avoid as much as possible to contact between two different
points in a circuit.
 Special insulated shoes are made to protect persons but
they must be clean and dry.
 While using high voltage machines in laboratory ensure
proper and tight connections.
 Must power off first and remove all the connected wires
from an electrical equipment.
 Avoid running extension wires across your doorways.
 Do not overload a single phase outlet, otherwise excess
power will be drawn

9. PRECAUTION IS BETTER THAN CURE.
STAY SAFE & HELP OTHERS LEARN SAFETY.
