EMERGENCY OVERVIEW
Appearance: clear almost colorless liquid. Flash Point: 5 deg C.
Danger! May be fatal if inhaled. Causes eye and
skin burns. Flammable liquid and vapor.
Harmful if swallowed. Lachrymator (substance which increases the
flow of tears). May be harmful if absorbed through the skin. May
cause severe digestive tract irritation with possible burns. May
cause severe respiratory tract irritation with possible burns. Keep
refrigerated. (Store below 4°C/39°F.) Moisture sensitive.
Target Organs: Lungs, eyes, skin, mucous
membranes.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Lachrymator (substance which increases the flow of tears).
Skin:
May be absorbed through the skin in harmful amounts. May cause
severe irritation and possible burns.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns.
Inhalation:
May be fatal if inhaled. Causes chemical burns to the respiratory
tract. Vapors may cause dizziness or suffocation.
A harmful contamination of the air can be reached very quickly on
evaporation of this substance at 20°C.
Chronic:
No information found.
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:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
Evacuate area and fight fire from a safe distance. As in any fire,
wear a self-contained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors
may form an explosive mixture with air. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion. Use water spray to keep fire-exposed containers cool.
Flammable liquid and vapor. Approach fire from upwind to avoid
hazardous vapors and toxic decomposition products. Vapors are
heavier than air and may travel to a source of ignition and flash
back. Vapors can spread along the ground and collect in low or
confined areas. 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:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Do NOT use water directly on fire. Use water
spray to cool fire-exposed containers. Water may be ineffective. Do
NOT use straight streams of water.
Flash Point: 5 deg C ( 41.00 deg F)
Autoignition Temperature: 485 deg C ( 905.00 deg F)
Explosion Limits, Lower:7.8 vol %
Upper: 23.3 vol %
NFPA Rating:
(estimated) Health: 4; Flammability: 3; Instability: 1
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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors. Evacuate
unnecessary personnel. Approach spill from upwind.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. 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 pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames. Do
not breathe vapor. Keep away from heat, sparks and flame. Use only
with adequate ventilation or respiratory protection.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Refrigerator/flammables. Do not store in metal containers. Store
protected from moisture.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Ventilation fans and
other electrical service must be non-sparking and have an
explosion-proof design. Use substance with extreme caution and
designate regulated areas for use. Use process enclosure, local
exhaust ventilation, or other engineering controls to control
airborne levels. Utilize a closed system process where feasible.
