CONFINED SPACE SAFETY NOTES – KNOW BEFORE YOU ENTER!

 CONFINED SPACE SAFETY NOTES – KNOW BEFORE YOU ENTER! ⚠️

📌 WHAT IS A CONFINED SPACE?
Enough space to enter & work, but limited entry/exit — NOT designed for continuous work.
Examples: Tanks, vessels, silos, pipelines, sewers, manholes, boilers, trenches, ducts, towers.

📊 SAFE GAS LEVELS (ARAMCO STANDARDS):
✅ Oxygen (O₂): 19.5% – 23.5% | Normal = 20.9%
✅ Flammable Gas (LEL): < 10% | 0% IDEAL
✅ Hydrogen Sulfide (H₂S): < 10 ppm | ACTION if >10 ppm
✅ Carbon Monoxide (CO): < 25 ppm (STEL)
✅ Carbon Dioxide (CO₂): < 0.5% (5000 ppm) | ACTION if >0.5%
✅ Other Toxic Gas: Follow SDS & IH guidelines
🛑 BEFORE ENTRY – 10 MANDATORY STEPS:
1️⃣ Get Confined Space Entry Permit (CSEP)
2️⃣ Identify ALL hazards
3️⃣ ISOLATE → Lock-Out Tag-Out (LOTO)
4️⃣ Drain, flush, clean, remove residues
5️⃣ VENTILATE & PURGE fully
6️⃣ TEST ATMOSPHERE (gas levels) & RECORD
7️⃣ Keep ventilation running while working
8️⃣ Good lighting
9️⃣ Clear communication system
🔟 RESCUE EQUIPMENT READY (tripod, winch, harness, SRL)
💡 RULE:
NO PERMIT • NO TEST • NO VENTILATION • NO ENTRY!
One wrong step = FATAL RISK. Safety first, every entry, every time!
