98-88-4 Benzoyl chloride >98 202-710-8

Section 3 - Hazards Identification


Appearance: clear, colorless liquid. Flash Point: 68 deg C.
Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. Harmful if absorbed through skin or if inhaled. Combustible liquid and vapor. Material hydrolyzes in contact with moisture/water releasing toxic and corrosive fumes of hydrogen chloride and aqueous hydrochloric acid.
Target Organs: Lungs, eyes, skin.

Potential Health Effects
Eye: Lachrymator (substance which increases the flow of tears). Causes severe eye irritation and burns.
Skin: Harmful if absorbed through the skin. Causes severe skin irritation and burns. AIHA uses a dermal sensitizer notation for this chemical.
Ingestion: May cause severe and permanent damage to the digestive tract.
Inhalation: Harmful if inhaled. Causes chemical burns to the respiratory tract. May cause pulmonary edema and severe respiratory disturbances. Vapors may cause lung injury. Exposures at 2 ppm for 1 minute have been reported as being intolerable.
Chronic: Animal studies have reported the development of tumors by skin contact. Skin and lung tumors were reported in mice after repeated skin contact with benzoyl chloride. These tumors were not considered statistically significant from the

Section 4 - First Aid Measures

Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors can travel to a source of ignition and flash back. Combustible liquid and vapor. Use of water will produce irritating and toxic vapors of hydrogen chloride. Hydrochloric acid solutions react with most metals, forming flammable hydrogen gas.
Extinguishing Media: Do NOT get water inside containers. Use dry powder or carbon dioxide.
Flash Point: 68 deg C ( 154.40 deg F)
Autoignition Temperature: 568 deg C ( 1,054.40 deg F)
Explosion Limits, Lower:1.2 vol %
Upper: 4.9 vol %
NFPA Rating: (estimated) Health: 3; Flammability: 2; Instability: 2; Special Hazard: -W-

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. Do not expose spill to water. Approach spill from upwind.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not allow contact with water. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Keep from contact with moist air and steam. Keep away from heat and flame. Systems and equipment must be scrupulously dry.
Storage: Keep away from sources of ignition. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Do not store near alkaline substances. Store protected from moisture. Separate from alcohols. Sometimes packaged under dry nitrogen.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
