**** 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.
