๐จ STERILIZER SAFETY – HIGH PRESSURE ZONE
⚠️ TOP RISK
Sterilizer Overpressure / Door Failure / Explosion
๐ด BEFORE OPERATION (PREVENTION)
✔ Check pressure gauge working & calibrated
✔ Ensure drain line NOT blocked
✔ Confirm door fully locked
✔ Verify interlock system ACTIVE (never bypass)
✔ Check steam valve condition
✔ Follow correct steaming SOP
๐ข DURING OPERATION
✔ Monitor pressure continuously
✔ Do NOT exceed safe pressure limit
✔ Listen for abnormal sound / vibration
✔ Ensure no leakage at door or pipeline
✔ Stay within safe distance
๐ต AFTER OPERATION
✔ Fully depressurize before opening door
✔ Open door slowly (confirm zero pressure)
✔ Inspect for damage / leakage
✔ Record operation in logbook

⚡ GOLDEN RULES
❌ NEVER bypass interlock
❌ NEVER open under pressure
❌ NEVER ignore alarm
✅ 2. OPERATOR CHECKLIST (Daily Use)
