Principle Routes of Exposure

Only when used as directed

Classification system

In compliance with OSHA’s Hazard Communication Standard (29CFR 1910.1200), a chemical mixture is considered hazardous if it contains 1.0% or more of a hazardous compound or 0.1% or more of a carcinogen. The product contains hazardous material(s) in excess of these amounts; therefore, precautions adequate for the pure form of the material(s) are presented here. National Fire Protection Association (NFPA) ratings (scale 0-4): Health=0 Fire=0 Reactivity=0 Hazard Overview Health: Minimal risk if used as directed. Fire: Not considered a fire hazard. Reactivity: Urea Nitrogen Acid Reagent contains Sulfuric Acid. Minimal risk. Special Hazards Sulfuric Acid With heat (at 340°C), it decomposes into toxic oxides of sulfur Carcinogenicity information OSHA (Occupational Safety and Health Administration): None of the ingredients is listed. NTP (National Toxicology Program): None of the ingredients is listed. IARC (International Agency for Research on Cancer): None of the ingredients is listed.
