🔍 Key Concepts

• Hydrogen sulfide (H2S) exposure limits used in offshore and industrial safety standards • Difference between a warning (low level) alarm and a high level / evacuation alarm • Typical OSHA/NIOSH recommended exposure limits in parts per million (PPM)

💭 Think About

• Which of these values is closest to the commonly used time‑weighted average exposure limit for H2S in many safety standards? • Would a low‑level alarm be set below, at, or above the long‑term exposure limit to give workers time to react? • Which value seems reasonable as an early warning, leaving room for a higher‑level alarm at a more dangerous concentration?

✅ Before You Answer

• Check typical 8‑hour exposure limits for H2S set by major standards bodies (OSHA PEL, NIOSH REL) and note the PPM value. • Verify that a low level alarm is meant as a preventive early warning, not a life‑threatening concentration. • Ensure that the level you pick leaves space for a higher high‑level alarm (e.g., at or near short‑term exposure or IDLH levels).
