HYDROGEN SULFIDE

SECTION 2: Hazards identification

Physical state Gas. Color Colorless. Emergency overview DANGER ! EXTREMELY FLAMMABLE GAS. MAY CAUSE FLASH FIRE. CAUSES EYE IRRITATION. GAS MAY CONTAIN HYDROGEN SULFIDE (H2S) GAS WHICH CAN BE HARMFUL OR FATAL IF INHALED. Hydrogen sulfide (H2S) has a characteristic "rotten egg" odor and at concentrations above 50 ppm, or prolonged exposures to lower concentrations, may dull the sense of smell so that the odor of the gas may not be apparent. DO NOT DEPEND ON THE SENSE OF SMELL TO DETECT H2S. Contains gas under pressure. Extremely flammable gas. In a fire or if heated, a pressure increase will occur and the container may burst or explode. Very toxic by inhalation. Keep away from heat, sparks and flame. Do not puncture or incinerate container. Do not breathe gas. Do not get on skin or clothing. Avoid contact with eyes. Use only with adequate ventilation. Keep container tightly closed and sealed until ready for use. Wash thoroughly after handling.

Principle Routes of Exposure

Dermal contact. Eye contact. Inhalation.

Potential health effects

Eyes Causes eye irritation. Skin No significant health hazards identified. Inhalation Harmful or fatal if inhaled. Hydrogen sulfide (H2S) has a characteristic "rotten egg" odor and at concentrations above 50 ppm, or prolonged exposures to lower concentrations, may dull the sense of smell so that the odor of the gas may not be apparent. DO NOT DEPEND ON THE SENSE OF SMELL TO DETECT H2S. See toxicological information (section 11). Ingestion Not applicable (gas). See toxicological information (section 11)
