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
Target Organs: Lungs, eyes, skin.
Potential Health Effects
Lachrymator (substance which increases the flow of tears). Causes
severe eye irritation and burns.
Harmful if absorbed through the skin. Causes severe skin irritation
AIHA uses a dermal sensitizer notation for this chemical.
May cause severe and permanent damage to the digestive tract.
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
Animal studies have reported the development of tumors by skin
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
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
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.
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.
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
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.
Do NOT get water inside containers. Use dry powder or carbon

Upper: 4.9 vol %
(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.
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
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.
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
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.

0.5 ppm Ceiling
OSHA Vacated PELs:
No OSHA Vacated PELs are listed for this chemical.
Personal Protective Equipment
Wear chemical splash goggles.
Wear appropriate protective gloves to prevent skin
Wear appropriate protective clothing to prevent skin
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 respirator use.

- IARC: Group 2A carcinogen
Based on case reports & epidemiological studies, workers
engaged in benzoyl chloride production have been at
increased risk to contract lung cancer. But, excess cancer
cases were likely due to excessive benzotrichloride
exposure & poor industrial hygiene
