Which is exactly why workers in battery rooms, hydrogen refueling stations, fuel cell manufacturing, and refinery hydrotreating rely entirely on continuous monitoring there's no sensory backup, and no OSHA PEL to signal "over exposure." Hydrogen isn't like the other gases you monitor. It doesn't have a toxicity story: OSHA has no permissible exposure limit for H2, and there's no smell or
