I was unable to find specific documentation regarding required safety training procedures for hydrogen sulfide (H2S) exposure prevention and emergency response in our current safety knowledge base, but here are industry-standard safety guidelines:

General safety training should cover the following:

1. Hazard Recognition: Training on the properties, sources, and potential health hazards of H2S. H2S is a colorless gas with a rotten egg odor and is extremely flammable. It can cause irritation to the eyes and respiratory system, and can be fatal if inhaled at high concentrations

2. Exposure Limits: Information on the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) for H2S, including Time-Weighted Average (TWA) and Short-Term Exposure Limit (STEL).

3. Engineering Controls: Training on the use of local exhaust ventilation, process enclosure, non-sparking ventilation systems, explosion-proof equipment, and intrinsically safe electrical systems to control H2S levels in the air

4. Personal Protective Equipment (PPE): Proper selection, use, and maintenance of PPE, including chemical safety goggles, face shields, chemical protective clothing (e.g., gloves, aprons, boots), and respirators. Specific recommendations for respiratory protection based on H2S concentration levels should be included.

5. Emergency Response Procedures: Comprehensive training on emergency response procedures, including evacuation protocols, rescue techniques, first aid measures, and proper use of emergency equipment. Training should emphasize the importance of self-rescue and avoiding mouth-to-mouth contact during rescue operations

6. First Aid Measures: Training on first aid procedures for inhalation, skin contact, and eye contact, including the importance of immediate medical attention. Note that some first aid procedures require advanced training and should be reviewed by a medical professional

7. Handling and Storage Practices: Training on safe handling and storage practices, including proper ventilation, elimination of ignition sources, and avoidance of incompatible materials. Cylinders should be secured, protected from damage, and moved using a suitable hand truck

8. Unintentional Release Measures: Training on procedures for responding to unintentional releases, including evacuation, isolation of the hazard area, ventilation, and elimination of ignition sources. Use grounded, explosion-proof equipment.
