SPECIAL FIRE FIGHTING PROCEDURES Use special breathing equipment and protective clothing appropriate to surrounding fire. UNUSUAL FIRE OR EXPLOSION HAZARDS Not considered to be an explosion hazard. Reaction with incompatible Materials may pose an explosion hazard. ****************************************************************************** SECTION V REACTIVITY DATA ****************************************************************************** Thermal Stability: Stable under ordinary conditions of use and storage. INCOMPATIBILITY Potassium, sodium, hydrazine, nitromethane, aluminum, strong oxidizers, Acetylene, and sodium hypobromite. CONDITIONS TO AVOID: not determined. HAZARDOUS POLMERIZATION: will not occur. HAZARDOUS DECOMPOSITION PRODUCTS Emits toxic fumes when heated to decomposition. ****************************************************************************** SECTION VI HEALTH HAZARD INFORMATION ****************************************************************************** EFFECTS OF OVEREXPOSURE SYMPTOMS OF INGESTION: May cause burning pain in the mouth, esophagus, and stomach. Hemorrhagic gastritis, nausea, vomiting, abdominal pain, metallic taste, and diarrhea may occur. If vomiting does not occur immediately systemic copper poisoning may occur. Symptoms may include capillary damage, headache, cold sweat, weak pulse, kidney and liver damage, central nervous excitation followed by depression, jaundice,

convulsions, paralysis and coma. Death may occur from shock or renal failure. SYMPTOMS OF INHALATION: May cause irritation of the upper respiratory tract. Symptoms may include coughing, sore throat, and shortness of breath. May also cause symptoms similar to the common cold, including chills and stuffiness of the head. SYMPTOMS OF SKIN CONTACT: May cause irritation, redness, and pain. SYMPTOMS OF EYE CONTACT: May cause irritation, redness, pain, discoloration, and damage. CHRONIC EXPOSURE Prolonged or repeated skin exposure may cause dermatitis. prolonged or repeated exposure to dusts of copper salts may cause discoloration of the skin or hair, ulceration and perforation of the nasal septum, runny nose, metallic taste, atrophic changes, and irritation of the mucous membranes. TOXICITY DATA: oral toxicity: LD50; 190 mg/kg (MUS) (CUCL2) ****************************************************************************** SECTION VII EMERGENCY AND FIRST AID PROCEDURES ****************************************************************************** EYE CONTACT: Immediately flush with copious amounts of water for at least 15 minutes while holding eyelids apart. Washing within one minute is essential to achieve maximum effectiveness. Get medical attention after flushing. SKIN CONTACT: Wash affected area thoroughly with soap and water. Remove contaminated clothing and launder before reuse. If irritation should develop, get medical attention. INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Consult a physician.

3 INGESTION: Never give anything by mouth to an unconscious person. INDUCE VOMITING by giving two glasses of water or milk if available and sticking finger down throat. Call a physician immediately. NOTES TO PHYSICIAN: Take appropriate action to counteract symptoms. ************************************************************************** SECTION VIII − INDUSTRIAL HYGIENE AND OCCUPATIONAL CONTROL PROCEDURES ************************************************************************** VENTILATION: A system of local exhaust is recommended to keep employee exposure below the Airborne Exposure Limits. Local exhaust is usually preferred because it controls the emission at its source, preventing dispersion of it into the general work area. Refer to the ACGIH document "Industrial Ventilation, A Manual of Recommended Practices" for details. RESPIRATORY PROTECTION: NIOSH/MSHA approved respirator if exposure may, or does exceed occupational exposure limits. Generally, a dust/mist respirator may be worn in areas where the TLV is exceeded up to ten times. Alternatively, a supplied air full facepiece respirator or airlined hood may be worn. EYE PROTECTION: Chemical splash goggles or face shield. Contact lenses should not be worn when working with this material. An eye wash fountain and quick−drench facilities should be maintained in the work area. SKIN PROTECTION: Use rubber or plastic impervious gloves and body−covering clothing. PERSONAL HYGIENE: Wash thoroughly after handling. ************************************************************************** SECTION IX − SAFE HANDLING, STORAGE AND USE PRECAUTIONS ************************************************************************** PRECAUTIONARY MEASURES: Avoid contact with skin, eyes and clothing. Wear protective clothing, gloves and splash goggles or shield. Wash thoroughly after using. Avoid breathing dust or mist. Use with adequate ventilation.

STORAGE AND HANDLING: Store in a cool, dry place and isolated from incompatible materials. Protect from physical damage.
