What is Diborane?
Diborane is a colorless gas with a repulsive, sweet odor. It is highly unstable as it mixes easily with air and forms explosive mixtures. Diborane ignites spontaneously in moist air at room temperature. Diborane is used in rocket propellants, as a reducing agent, catalyst for hydrocarbon polymerization, and as a doping agent. It also is used in electronics to impart electrical properties to pure crystals. Diborane is extremely flammable and may explode if heated under pressure. It is a strong irritant and is toxic if inhaled causing organ damage.
Diborane Exposure and Health Risks
Diborane is toxic when inhaled. Whether short term exposure to high concentrations or long term exposure to low concentrations, diborane inhalation will result in adverse health effects like organ damage. Symptoms can appear immediately, but can be delayed for hours after exposure. Symptoms of diborane exposure include wheezing, coughing, shortness of breath, and chest pain. Diborane is highly toxic whether by inhalation, skin absorption, or ingestion. Lung and kidney damage is likely in the case of diborane poisoning. Diborane is a strong irritant, causing damage to skin, eyes, and mucous membranes.
