Ethyl mercaptan 75-08-1 682 ppm (rat) Not available 2770 ppm, (mouse), 4H Likely Routes of Exposure: Eye contact. Skin contact. Inhalation. Symptoms (including delayed and immediate effects) Inhalation: This product is an asphyxiant gas that can cause unconsciousness and/or death if oxygen levels are sufficiently reduced. Together these processes are referred to as "odor fade." In effect the ethyl mercaptan reacts with its surroundings, e.g., rust in the container, oxygen or moisture in the environment, causing the chemical to lose its strong, warning odor. If "odor fade" occurs the propane is not detectible at nose level, as required by state regulation.
