Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Causes burns.Corrosive.Moisture sensitive.Lachrymator (substance which increases the flow of tears).Possible risks of irreversible effects.
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.
Ingestion:
Harmful if swallowed. 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.
Chronic:
Laboratory experiments have resulted in mutagenic effects. Animal studies have reported the development of tumors by skin contact.

Section 4 - FIRST AID MEASURES
  Eyes: Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:

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. Use water spray to keep fire-exposed containers cool. Will react with water to form toxic and corrosive fumes. Water Reactive.
Combustible Liquid. Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. DO NOT USE WATER! Do NOT get water inside containers. For small fires, use dry chemical or carbon dioxide. For large fires, flood fire area with large quantities of water, while knocking down vapors with water fog.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective Equipment section. Scoop up with a nonsparking tool, then place into a suitable container for disposal. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation. Use water spray to reduce vapors, do not put water directly on leak, spill area or inside container. Cover with dry earth, dry sand, or other non-combustible material followed with plastic sheet to minimize spreading and contact with water.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. 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. Avoid contact with heat, sparks and flame. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. 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.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances.
Keep away from water. Corrosives area. Do not store near alkaline substances. Store protected from moisture. Separate from alcohols.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use only under a chemical fume hood.
Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Section 12 - ECOLOGICAL INFORMATION
  Ecotoxicity:
Fish: Fathead Minnow: LC50 = 35 mg/L; 96 Hr; UnspecifiedBacteria: Phytobacterium phosphoreum: EC50 =10.4-12.2 mg/L; 5,15,30 min; Microtox test at 15 CFish: Bluegill/Sunfish: 200 ppm; 7 Hr; Unspecified (Fresh water)No data concerning the hydrolysis of benzoyl chloride in soil is available. The hydrolysis half-life is so short that the predominant terrestrial fate of benzoyl chloride is expected to be hydrolysis. In the absence of water, however, benzoyl chloride could form a variety of esters upon reaction with common soil constituents. Benzoyl chloride per se is not expected to adsorb to soils, biodegrade, photolyze, volatilize or leach to groundwater.
Other Harmful to aquatic life in very low concentrations.

Section 13 - DISPOSAL CONSIDERATIONS
  Products which are considered hazardous for supply are classified as Special Waste and the disposal of such chemicals is covered by regulations which may vary according to location. Contact a specialist disposal company or the local waste regulator for advice. Empty containers must be decontaminated before returning for recycling.
