Memo to Erica Crosby. File No. M-90-57 7 October 18, 2001 recommends [ha[ organic materials classified as RCRA hazardous wastes be disposed of by thermal treatment or incineration at EPA approved facilities. Cytec has provided the foregoing for information only; the person generating the waste is responsible for deterntining the waste classification and disposal method. Health Hazards: EFFECTS OF OVEREXPOSURE: 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 burns 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 [he sense of smell. Therefore, odor is an unreliable indicator of exposure. Overexposure to hydrogen sulfide gas may cause severe eye or respiratory tract im[ation, 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 [o control exposure. Food, beverages, and tobacco products should no[ be carried, stored, or consumed where [his 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 the material and level of exposure. See "GUIDE TO INDUSTRIAL RESPIRATORY PROTECTION"(NIOSH). Sulahur Dioxide MAJOR HEALTH HAZARDS: respiratory tract burns, skin burns, eye burns, allergic reactions PHYSICAL HAZARDS: Containers may rupture or explode if exposed to heat. 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: burns LONG TERM EXPOSURE: same as effects reported in short term exposure EYE CONTACT: SHORT TERM EXPOSURE: burns, tearing, blindness LONG TERM EXPOSURE: same as effects reported in short term exposure
