The acute oral (rat) and dermal (rabbit) LD50 values for this product are 8.46 g/kg and 5.6 g/kg, respectively. Direct contact with this material may cause severe eye imtation and chemical bums of the skin. Contact with acid may cause liberation of hydrogen sulfide. Hydrogen sulfide has a strong rotten-egg odor, however, some people are unable to smell the gas and exposure will deaden the sense of smell. Therefore, odor is an unreliable indicator of exposure. Overexposure to hydrogen sulfide gas may cause severe eye or respiratory tract irritation, rapid development of coma and respiratory failure. Low levels of hydrogen sulfide may cause headache, dizziness, staggering gait, neurological damage and gastritis. ENGINEERING CONTROLS AND PERSONAL PROTECTIVE EQUIPMENT (PPE): Utilize a closed system process where feasible. Where this material is not used in a closed system, good enclosure and local exhaust ventilation should be provided to control exposure. Food, beverages, and tobacco products should not be carried, stored, or consumed where this material is in use. Before eating, drinking, or smoking, wash face and hands with soap and water. Prevent eye and skin contact. Wear the special protective equipment specified below for operations where eye or skin contact can occur. Prevent contamination of skin or clothing when removing protective equipment. Provide eyewash fountain and safety shower in close proximity to points of potential exposure. Where exposures are below the PEL, no respiratory protection is required. Where exposures exceed the PEL, use respirator approved by NIOSH or full protective suit with air supply appropriate for [he material and level of exposure. See "GUIDE TO WDUSTRIAL RESPIRATORY PROTECTION"(NIOSH).

POTENTIAL HEALTH EFFECTS: INHALATION: SHORT TERM EXPOSURE: allergic reactions, burns, nausea, vomiting, stomach pain, chest pain, difficulty breathing, bluish skin color, lung damage, convulsions LONG TERM EXPOSURE: wheezing, lung damage SKIN CONTACT: SHORT TERM EXPOSURE: bums LONG TERM EXPOSURE: same as effects reported in short term exposure EYE CONTACT: SHORT TERM EXPOSURE: bums, tearing, blindness LONG TERM EXPOSURE: same as effects reported in short term exposure Storage Considerations: Store and handle in accordance with all current regulations and standards. Protect from physical damage. Store outside or in a detached building. Store in awell-ventilated area. Keep separated from incompatible substances. Notify Slate Emergency Response Commission for storage or use at amounts greater than or equal to the TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires facilities storing a material with a TPQ to participate in local emergency response planning (U.S. EPA 40 CFR 355.30).
