⚠️ Introduction: Why This Training Matters

“Imagine being trapped in a space no bigger than a closet. The air suddenly turns toxic. You can’t scream. You can’t escape. This isn’t a horror movie—it’s what happens in real confined space accidents. In the last year alone, [X] workers didn’t make it home because they underestimated these dangers.”

“Today’s training will teach you how to:
1️⃣ Recognize confined space hazards
2️⃣ Test atmospheres like a pro
3️⃣ Enter & work safely
4️⃣ Rescue without becoming a victim yourself”

🔍 Section 1: What Exactly is a Confined Space?

“It’s not just about size—it’s about danger. A confined space has:
✓ Limited entry/exit points
✓ Not designed for continuous occupancy
✓ Potential for hazardous atmosphere or engulfment”

Common Examples:
• Storage tanks
• Sewers
• Silos
• Utility vaults
• Even some large equipment when locked out

☠️ Section 2: The Silent Killers

“You can’t see, smell, or taste these threats:”

1. Oxygen Problems
• Too little (<19.5%) = Dizziness → Death
• Too much (>23.5%) = Everything becomes flammable

2. Toxic Gases
• H2S (Rotten egg smell) – Knocks you out at 100ppm
• CO (No odor) – Binds to blood 200x faster than oxygen

3. Flammable Atmospheres
• Just 10% LEL can explode

4. Physical Hazards
• Engulfment
• Moving parts
• Extreme temperatures

“This reading shows 2% oxygen—you’d be unconscious before reaching the bottom rung.”

✅ Section 3: The Entry Permit System

*”No permit = NO ENTRY. Ever. Permits ensure we:*
✔ Test air quality
✔ Lock out hazards
✔ Assign roles
✔ Prep rescue plans”

Critical Permit Elements:
✓ Continuous monitoring (Conditions can change!)
✓ Attendant stationed outside
✓ Time limits
✓ Emergency contacts

*[Show a blanked-out real accident report]*
“This crew skipped permits to ‘save time.’ They never clocked out.”

🎯 Section 4: Safe Entry Procedures

“Follow these steps religiously:”

1. Isolate the space (Lockout/Tagout)
2. Purge/Ventilate (Don’t trust natural airflow)
3. Test atmosphere (Top/middle/bottom – gases stratify!)
4. Use PPE (Harnesses, SCBA if needed)
5. Communicate (Hand signals when radios fail)

🚨 Section 5: Rescue – The Deadliest Phase

*”60% of confined space fatalities are would-be rescuers. Remember:*

NEVER enter without:
• Backup team ready
• Proper air supply
• Full protective gear

Non-Entry Rescue First:
• Use retrieval systems
• Mechanical advantage

💡 Section 6: Real-World Scenarios

“Let’s test your judgment:”

Scenario 1:
“The monitor shows 20.9% O2 but smells ‘funny.’ Green light to enter?”
→ NO! Some deadly gases don’t affect O2 readings

Scenario 2:
“You’re alone and see a coworker collapse inside. Jump in?”
→ NEVER! Call pros and prevent more deaths

✅ Conclusion: Your Life-Saving Pledge

“Repeat after me:
‘I will never enter without authorization.
I will trust my gas monitor over my instincts.
I will stop work if conditions change.'”

“Remember: There are old safety workers, and there are bold safety workers—but there are no old, bold safety workers.”

Closing

“Great work today! Remember: The most dangerous thing in any confined space is a complacent mind.”

❓ FAQs

Q: How often should we retest atmosphere?
A: Continuously! Conditions change with work activities.

Q: Can we use a shop fan for ventilation?
A: Only if specifically approved—most just stir up hazards.

Q: What’s the #1 mistake during entries?
*A: Assuming “it’s safe yesterday = safe today.”*

Q: Who can authorize entries?
A: Only trained Entry Supervisors after full hazard review.
