3. Hazards Identification
Emergency Overview
--------------------------
DANGER! MAY BE FATAL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN.
AFFECTS LIVER, KIDNEYS, CENTRAL NERVOUS SYSTEM AND GASTROINTESTINAL TRACT.
CAUSES SEVERE EYE IRRITATION. CAUSES IRRITATION TO SKIN AND RESPIRATORY
TRACT.
Potential Health Effects
----------------------------------
Generally considered the most
toxic of the common chlorinated hydrocarbons.
Inhalation:
Highly toxic. Strong irritant of the mucous membranes and upper
respiratory tract. Initial symptoms may include irritation of the nose and
throat, salivation. Continued exposure may produce restlessness, dizziness,
nausea, vomiting and narcosis. Symptoms may progress to a more serious illness
with jaundice, liver tenderness, lung edema, and possibly convulsions and coma
before death.
Ingestion:
Highly toxic via ingestion. Symptoms
parallel those from inhalation. Causes irritation to the gastrointestinal
tract. Symptoms may include nausea, vomiting and diarrhea.
Skin
Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain. May be absorbed through the skin with possible systemic effects.
Eye Contact:
Vapors cause eye irritation. Splashes cause severe
irritation, possible corneal burns and eye damage.
Chronic
Exposure:
Chronic exposure can produce the same life threatening
health effects noted for inhalation exposure above. Chronic exposure may also
affect liver, gastrointestinal tract and blood-forming organs.
Aggravation of Pre-existing Conditions:
Persons with
pre-existing skin, eye or central nervous system disorders, or impaired liver,
kidney, or pulmonary function may be more susceptible to the effects of this
substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Call a
physician immediately.
Ingestion:
Induce vomiting immediately
as directed by medical personnel. Never give anything by mouth to an
unconscious person. Call a physician immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of soap and water
for at least 15 minutes while removing contaminated clothing and shoes. Wash
clothing before reuse. Call a physician immediately.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least
15 minutes, lifting lower and upper eyelids occasionally. Call a physician
immediately.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
In the
event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Isolate hazard area. Keep
unnecessary and unprotected personnel from entering. Contain and recover
liquid when possible. Collect liquid in an appropriate container or absorb
with an inert material (e. g., vermiculite, dry sand, earth), and place in a
chemical waste container. Do not use combustible materials, such as saw dust.
Do not flush to sewer! US Regulations (CERCLA) require reporting spills and
releases to soil, water and air in excess of reportable quantities. The toll
free number for the US Coast Guard National Response Center is (800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Isolate from incompatible
substances. Containers of this material may be hazardous when empty since they
retain product residues (vapors, liquid); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure
Limit
5 ppm (TWA) skin
-ACGIH Threshold Limit Value (TLV):
1 ppm
(TWA) skin, A3 - Confirmed animal carcinogen
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant at
its source, preventing dispersion of it into the general work area. Please
refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal
Respirators (NIOSH Approved):
If the exposure limit is exceeded, wear
a supplied air, full-facepiece respirator, airlined hood, or full-facepiece
self-contained breathing apparatus. This substance has poor warning
properties.
Skin Protection:
Wear impervious protective
clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
Eye Protection:
Use
chemical safety goggles and/or a full face shield where splashing is possible.
Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures:
There is insufficient data in the
published literature to assign complete numerical SAF-T-DATA* ratings and
laboratory protective equipment for this product. Special precautions must be
used in storage, use and handling. Protective equipment for laboratory bench
use should be chosen using professional judgment based on the size and type of
reaction or test to be conducted and the available ventilation, with
overriding consideration to minimize contact with the chemical.
