Hydrogen (H2)
Hydrogen gas (H2) is primarily produced through industrial processes such as natural gas reforming, electrolysis of water, and biomass conversion. It is a colorless, odorless, and non-toxic gas under normal conditions.

Guidelines
- OSHA: No PEL for H2, but oxygen levels must remain above 19.5%.
- US EPA: No specific NAAQS, but hydrogen levels should be below the Lower Explosive Limit (LEL) of 4% in air
Health effects
- Asphyxiation: Displaces oxygen in confined spaces, leading to dizziness, confusion, and unconsciousness.
- Flammability: Highly flammable, forming explosive mixtures (4-75% hydrogen in air).
- Breathing Issues: High concentrations may cause dizziness, chest tightness, and difficulty breathing.
