🔍 Key Concepts

• Hydrogen sulfide (H₂S) toxicity levels and how effects increase as ppm rises • Difference between odor threshold, irritation level, immediately dangerous to life and health (IDLH), and lethal levels • Typical short-term exposure definitions in industrial / maritime safety guidance

💭 Think About

• Which of these ppm values is commonly associated with permanent harm or death after only a brief exposure, rather than just strong odor or irritation? • Think about where IDLH levels usually fall for H₂S, and then which value would reasonably be beyond that into clearly lethal territory. • Compare each option to what you know about H₂S dangers: at what level do safety procedures warn of collapse and possible death in minutes?

✅ Before You Answer

• Verify approximate IDLH level (immediately dangerous to life and health) for H₂S and then look for the option that clearly exceeds it into lethal range. • Confirm which level is associated with rapid unconsciousness and respiratory paralysis, not just eye and lung irritation. • Check safety references that distinguish between serious health effects and expected mortality for short-term exposure.
