⚡ Introduction: The Shocking Truth
“That tiny tingle you felt last week? That was 10mA of current—enough to kill under the wrong conditions. Electricity doesn’t give second chances. Last year, [X] workers died because they underestimated voltages you can’t even see.”
*”Today’s non-negotiable rules will teach you how to:*
1️⃣ Respect invisible energy that can stop your heart
2️⃣ Isolate circuits properly (Lockout/Tagout isn’t optional)
3️⃣ Work smart on/near live parts when absolutely necessary
4️⃣ Respond when someone gets shocked”

“This was a $20,000 mistake that cost a technician his fingers. Let’s make sure your story ends differently.”
⚠️ Section 1: How Electricity Kills
“It’s not the voltage—it’s the current path. Understand these death factors:”
Current Effects:
• 1mA → Barely feel it
• 10mA → Can’t let go
• 100mA → Ventricular fibrillation
• 1A → Cooks flesh from inside
Danger Zones:
• Wet conditions (Sweat makes you 100x more conductive)
• Confined spaces (Nowhere to fall safely)
• Overhead lines (Arc flash reaches 35,000°F)

🔒 Section 2: Lockout/Tagout (LOTO) or Die
“70% of electrical fatalities happen during maintenance. LOTO saves lives:”
6 Steps That Can’t Be Skipped:
- Prepare (Know all energy sources)
- Shut down (Follow procedure exactly)
- Isolate (Pull fuses, disconnect lines)
- Lock & Tag (Your lock = your life)
- Test dead (Verify with meter – test on known live first!)
- Release cautiously (Clear area before re-energizing)

“See how this ‘locked out’ panel still has backfeed? Assume nothing—test everything.”
👷 Section 3: Working Live (When Absolutely Necessary)
“If you must work energized, these rules aren’t negotiable:”
PPE Hierarchy:
- Voltage-rated gloves (Inspect for pinholes first!)
- Arc flash suit (Cal/cm² rating matters)
- Face shield + balaclava (Melted skin doesn’t heal well)
The 3-Foot/1-Foot Rules:
• Stay 3+ feet from 120V-750V
• Add 1 foot for every 10kV over 750V

“Regular clothes turn to napalm at 500°C. Your FR gear buys you 4 seconds to escape.”
🚨 Section 4: Emergency Response
“If someone’s being shocked:”
- Call 911 FIRST (Cardiac arrest starts immediately)
- Kill power (Pull plug, hit disconnect)
- Never touch them directly (You’ll become path to ground)
- Start CPR if trained (Most need defibrillation)

💡 Section 5: Real-World Scenarios
“Test your judgment:”
Scenario 1:
“A coworker says ‘It’s just 120V—I’ll work it hot to save time.’ Your move?”
→ STOP THEM (More 120V deaths than any other voltage)
Scenario 2:
“You smell ozone near a panel but no breakers tripped. Proceed?”
→ EVACUATE (Hidden arc flash could detonate any second)
✅ Conclusion: Your Electrical Survival Pledge
“Repeat after me:
‘I will verify every circuit is dead myself.
I will treat all wires as live until proven otherwise.
I will walk away from unsafe work—no matter the pressure.'”
“Remember: There are old electricians and bold electricians… but no old, bold electricians.”

❓ FAQs
Q: How often should voltage-rated gloves be tested?
A: Before each use AND professionally every 6 months.
Q: Can I use regular gloves for electrical work?
A: NEVER—they offer zero protection (show puncture test).
Q: What’s the #1 LOTO mistake?
A: Not verifying isolation (“I turned it off” isn’t enough).
Q: Who can work on live circuits?
A: Only qualified persons with written justification.
