It is frequently used near its production site, with the two main uses https://vimeo.com/430827187 being petrochemical processing and ammonia production. It is a flammable gas that is colorless, odorless and lighter than air. It is nontoxic, but can act as a simple asphyxiant in confined spaces. Hydrogen is normally transported between industrial facilities as a gas.Indications of a LeakA hissing or whistling noiseAn unusual area of melted snow in the winterAn area of dead vegetationBubbling in pools of water Hazards of a ReleaseHighly flammable and easily ignited by heat or sparksWill displace oxygen and can cause asphyxiationFire may produce irritating and/or toxic gasesVapors may form an explosive mixture with airVapors may cause dizziness or asphyxiation without warningIs lighter than air can migrate underground and into enclosed spaces16 2022 by Pipeline Association for Public Awareness'
