Electrical safety is the top priority area for industries as electrical accidents can cause fatalities. Some key risks include electric shock, electrical burns, and fires. The risk of electric shock depends on voltage, current, resistance of the body, and other factors. Industries must implement proactive safety management programs that focus on controlling equipment and material performance, as well as human performance through proper training and use of personal protective equipment. Reactive approaches like emergency plans and first aid treatment are also important.

2. ELECTRICAL SAFETY
TOP PRIORITY AREA
• No warning
• Probability for fatality high
• Minimum 15 persons die out of electric
shock every day
• 35% of the fires are due to electricity

3. ELECTRICAL HAZARD
CONSEQUENCES
• Electric Shock
• Electrical Burns
• Electrical Fire & Explosion

4. ELECTRICAL SHOCK
• VOLTAGE
• CURRENT
• RESISTANCE

5. VOLTAGE
• Low voltage (Up to 250 V)
• Medium Voltage (Up to 650 V)
• High Voltage(Up to 33 KV)
• Extra High Voltage(Above 33 KV)

6. ELECTRIC CURRENT
• Magnitude
• Duration
• Type
• Frequency

7. HUMAN BODY RESISTANCE
• Dry Body Resistance( 1 to 4 Lakh Ohm)
• Wet Body Resistance (1000 Ohm)
• Ear to Ear (100 Ohm)

8. ELECTRIC SHOCK
CONTRIBUTING FACTORS
• Magnitude of current through the body
• Type of current (AC/DC)
• Frequency
• Voltage
• Resistance offered by the body(Natural/Artificial)
• Path selected through the body(Hand/leg/Heart)
• Sex(Male/Female)
• Mental State

9. ELECTRICAL SHOCK
CONTROL OF CONSEQUENCES
• By increasing the Body
resistance(Natural/Artificial)
• By reducing the duration of flow of electric
current
• By providing a low resistance path to the
earth and diverting the current away from
the body
• By maintaining safe separation distance

10. ELECTRICAL SAFETY
MANAGEMENT
• SCIENCE AND ART
• Control of Equipment Performance
• Control of Material Performance
• Control of Machine Performance
• Control of MAN Performance
