Section III. Hazards Identification Emergency Overview Clear. Liquid. Pungent. Acrid odor. DANGER! CAUSES SEVERE EYE, SKIN AND RESPIRATORY TRACT BURNS. MAY CAUSE BLINDNESS. HARMFUL IF ABSORBED THROUGH SKIN. MAY BE HARMFUL IF INHALED. MAY BE HARMFUL IF SWALLOWED. COMBUSTIBLE LIQUID AND VAPOR. Potential Health Effects Inhalation and skin contact are expected to be the primary routes of occupational exposure to benzoyl chloride. Direct contact with liquid will cause eye, skin, respiratory and digestive tract burns. Vapors are irritating to the eyes, skin and respiratory tract. May cause a build up of fluids in the lungs (pulmonary edema) that may cause death. May cause central nervous system depression.

Benzoyl chloride is considered, on the basis of single exposure (acute) animal tests, to be moderately toxic if absorbed through the skin and slightly toxic if swallowed.

Section IV. First Aid Measures Eye Contact Immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately. Skin Contact In case of contact, immediately flush skin with plenty of water for at least 15 minutes, while removing contaminated clothing and shoes. Contact a Poison Control Center. Get medical attention immediately. Wash clothing before reuse. Destroy contaminated shoes. Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give [Benzoyl Chloride] Page 1 of 4 oxygen. Get medical attention immediately. Ingestion If swallowed, DO NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.

Section V. Fire and Explosion Data Flammability of the Product Combustible. Auto-Ignition Temperature 85°C (185°F) Flash Points OPEN CUP: 72°C (161.6°F) Flammable Limits LOWER: 1.2% UPPER: 4.9% Fire and Explosion Hazards When heated to decomposition, this material emits toxic fumes. This material may be an environmental hazard. Contain run-off from fire. Notify authorities if water pollution occurs. If this material contacts water, it will react to form heat and . If material does come in contact with water, use large amounts of water to hold down vapors and flush away acid. Fire Fighting Media Extinguish fire using agent suitable for surrounding fire with dry chemicals or carbon and Instructions dioxide. DO NOT use water. Violent reaction may result. Carefully use water spray to keep fire-exposed containers cool. Firefighters and others who may be exposed to products of combustion should wear full firefighting turn out gear and self-contained breathing apparatus. Firefighting equipment should be thoroughly decontaminated after use.

Section VI. Accidental Release Measures Small Spill Neutralize with lime, limestone, Portland cement or soda ash. Absorb with an inert material and put the spilled material in an appropriate waste disposal container. Large Spill Remove or shut off all sources of ignition. Stop leak if without risk. Absorb with dry earth, sand or other non-combustible material. Do not get water inside container. Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed.

Section VII. Handling and Storage Handling Do not taste or swallow. Do not get in eyes, on skin or on clothing. Do not breathe gas, fumes, vapor or spray. Keep container tightly closed. Use only in well ventilated areas. Wash thoroughly after handling. Storage Store in well ventilated area away from sources of ignition.

Section VIII. Exposure Controls/Personal Protection Engineering Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of Controls vapors below their respective threshold limit value. Ensure that eyewash station and safety shower is near the work-station location. Personal Protection Splash goggles. Full Suit. Vapor respirator. Be sure to use a MSHA/NIOCH approved respirator or equivalent. Gloves (impervious). Boots. Personal Protection in Splash goggles. Full suit. Boots. Gloves.

Section XI. Toxicological Information Toxicity to Animals Acute Oral toxicity (LD50): 1900 – 2618 mg/kg (Rat), Slightly toxic. Acute Dermal toxicity (LD50): 790 - >2000 mg/kg (Rabbit), Moderately to no more than slightly toxic. Acute toxicity of the mist (4-hr LC50): 72 >2000 mg/l (Rat); (2-hr LC50): 1870 mg/m3 (Rat) Eye Irritation – Corrosive (Rabbit) Skin Irritation – Moderately irritating, 3.8/8.0 (Rabbit)

Skin and lung tumors were reported in mice after repeated skin contact with benzoyl chloride. These tumors were not considered statistically significant from the control. Irritation of the eyes, skin and respiratory tract and excitation were observed in mice after repeated skin contact. Central nervous system depression was reported in mice after repeated skin contact.

No genetic changes were reported in standard tests using bacterial and yeast cells, both with and without mammalian metabolic activation. An equivocal response was reported in one standard test using bacterial cells without mammalian metabolic activation.

Section XII. Ecological Information Ecotoxicology Bluegill sunfish 1-hr LC50: 500 ppm Goldfish 7-hr LC50: 200 ppm Fathead minnow 24-hr LC50: 43 mg/l, Slightly toxic. Fathead minnow 48-hr LC50: 35 mg/l, Slightly toxic. Fathead minnow 96-hr LC50: 35 mg/l, Slightly toxic. Grass shrimp 96-hr LC50: 180 ppm, Practically non-toxic. Chemical Fate BOD: 165% Benzoyl Chloride is not likely to persist in the environment in its free state, due to its reactivity. It hydrolyzes in water to form benzoic acid and hydrochloric acids. Benzoyl Chloride may be dangerous to the environment if released to open waterways. Not expected to cumulate or persist in mammals, based on an elimination study in rats. Benzoyl Chloride is not expected to absorb in soils, biodegrade, photolyze, volatilize or leach to ground water.
