Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: clear colorless to slightly yellow liquid.
Danger! May be fatal if inhaled. Exposure through
inhalation may result in delayed pulmonary edema, which may be
fatal. Onset of acute lung injury after toxic exposure may be
delayed up to 72 hours after initial exposure. Causes burns by all
exposure routes. Water-reactive. Contact with water liberates toxic
gas. Lachrymator (substance which increases the flow of tears).
Harmful if inhaled or swallowed. Light sensitive.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye burns. Causes redness and pain. Lachrymator (substance
which increases the flow of tears). May cause chemical
conjunctivitis and corneal damage.
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts. Causes redness and pain.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract. Inhalation may be
fatal as a result of spasm, inflammation, edema of the larynx and
bronchi, chemical pneumonitis and pulmonary edema. Exposure through
inhalation may result in delayed pulmonary edema which may be fatal.
Death may result hours after initial exposure.
Toxic exposure to fumes of Thionyl Chloride reacting with water may
result in a delayed pulmonary response (longer than two weeks) of
bronchiolitis Obliterans-inflammation of the bronchioles.
Chronic:
Chronic exposure may cause effects similar to those of acute
exposure.
|
Section 4 - First Aid Measures
|
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes 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
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 and move 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:
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. Water reactive. Material will react with water and
may release a flammable and/or toxic gas. Containers may explode in
the heat of a fire. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Contact with
metals may evolve flammable hydrogen gas.
Extinguishing Media:
Do NOT use water directly on fire. If water is the only media
available, use in flooding amounts. Do NOT get water inside
containers. Cool containers with flooding quantities of water until
well after fire is out. For small fires, use dry chemical or carbon
dioxide.
Flash Point: Not applicable.
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 4; Flammability: 0; Instability: 2; Special Hazard: -W-
|
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. Use a spark-proof tool. Do not get water inside
containers. 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:
Keep container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Use with adequate ventilation. Store protected from
light. Do not allow contact with water. Discard contaminated shoes.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Corrosives area. Keep away from acids. Do not store in
metal containers. Store protected from light.
|
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. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Use only
under a chemical fume hood.
