What you'll learn

  • Describe the key properties of H₂S and explain why the sense of smell must never be relied on as a warning.
  • Identify where H₂S may be encountered in upstream operations, including low-lying areas and confined spaces.
  • Explain the health effects of H₂S at increasing concentrations and why site exposure limits and alarm setpoints govern.
  • Wear and check a personal gas detector correctly and respond to an alarm by moving upwind or crosswind to muster without investigating.
  • Distinguish escape sets (EEBD) from SCBA working sets and explain why rescue is only performed by trained SCBA wearers.
