1. H2S Awareness Training – Level 2 ADNOC Approved Safety Standard Trainer: __________ Date: __________

2. Introduction to H2S Toxic, flammable, corrosive gas Heavier than air – settles in low areas Odor not reliable – causes nose fatigue

3. Sources of H2S in ADNOC Operations Oil & gas reservoirs Drilling operations Production & processing facilities Sewage & confined spaces

4. Toxicology & Exposure Limits 10 ppm → Safe Work Limit 15 ppm → Short Term Exposure Limit 100 ppm → IDLH (Immediate Danger to Life & Health) Affects lungs, eyes, and nervous system

5. Health Effects by Concentration 10–50 ppm: Eye & throat irritation 100–200 ppm: Headache, nausea, dizziness 300–500 ppm: Collapse, unconsciousness 700+ ppm: Death within minutes

6. Detection & Monitoring Fixed H2S detectors (facility) Portable personal monitors Alarm levels (low/high) Calibration requirements

7. Safety Equipment Escape sets (EEBD) Self-Contained Breathing Apparatus (SCBA) Personal gas detector Location of muster points

8. Safe Work Practices Always wear personal detector in H2S risk areas Identify wind direction before entry Never enter confined space without testing & permit Do not rely on smell

9. Emergency Response Procedures Alarm sounds → stop work immediately Don EEBD/SCBA Move upwind / crosswind Muster point reporting Inform control room / emergency team

10. ADNOC Golden Rules If in doubt → GET OUT Safety above production No compromise with PPE

11. Case Study / Incident Example Example: Worker exposed to high H2S levels Fatal outcome due to lack of EEBD use Lessons: Always wear detector, use escape set, follow procedures

12. Quiz & Review Q1: What is the first action when detector alarms? Q2: Why is smell not reliable for H2S detection? Q3: What is IDLH level for H2S?
