Safety of Urea Production

Urea nitrogen is manufactured to be used in fertilizer, in the making of some plastics, in decreasing the emissions of diesel engines and also as a dietary supplement for cattle. Urea nitrogen is a natural byproduct of protein consumption, but it is also manufactured industrially.

  1. Appearance/Identification

    • Urea nitrogen is a gas. However, the manufacturing process of creating urea results in crystals that smell similar to urine.

    Symptoms of Urea Exposure

    • The Occupational Safety and Health Administration (OSHA) states that urea exposure can result in a burning in the throat, lungs and eyes, cough, difficulty breathing and, in severe cases, nausea, headache, fever and seizures.

    Health Effects

    • Urea exposure can permanently damage the lungs.

    Combustibility

    • Urea is highly combustible and was a significant component in the World Trade Center bomb of 1993.

    Prevention

    • In order to prevent explosion, temperatures need to remain below 132 degrees Celsius, and urea must not come in contact with chlorites, nitrites, oxidants or inorganic chlorides.
