Natural Gas (Sweet) - Odorized

SECTION 2: Hazards identification

Emergency Overview OSHA Flammable Gas. Can cause flash fire. Contents under pressure. Keep away from heat, sparks, flames, static electricity or other sources of ignition. Health effects of Natural Gas below the Lower Explosive Limit (LEL) are minimal. At high concentrations Natural Gas will displace air thereby reducing oxygen available for breathing. Symptoms of overexposure, which are reversible if exposure is stopped in time, can include shortness of breath, drowsiness, headaches, confusion, decreased coordination, visual disturbances and vomiting. Continued exposure can lead to hypoxia (inadequate oxygen), cyanosis (bluish discoloration of the skin), numbness of the extremities, central nervous system depression, cardiac sensitization, unconsciousness and death. Inhalation (Breathing): Asphyxiant – high concentrations in confined spaces may limit oxygen available for breathing. Skin: Not known to be a skin irritant. Skin absorption is unlikely. Eye: Not known to be an eye irritant. Ingestion (Swallowing): This material is a gas under normal atmospheric conditions and ingestion is unlikely. Signs and Symptoms: Light hydrocarbon gases are simple asphyxiants and can cause anesthetic effects at high concentrations. Symptoms of overexposure, which are reversible if exposure is stopped, can include shortness of breath, drowsiness, headaches, confusion, decreased coordination, visual disturbances and vomiting. Continued exposure can lead to hypoxia (inadequate oxygen), cyanosis (bluish discoloration of the skin), numbness of the extremities, central nervous system depression, cardiac sensitization, unconsciousness and death.
