Potential Health Effects
Inhalation:
Corrosive. Vapors irritate the respiratory tract causing coughing, chest pain,
orbreathing difficulties. Exposure to moderately high
concentrations of the vapor may cause severe pulmonary edema. Experimental
animals exposed to 100ppm showed severe heart tissue degeneration.
Ingestion:
Corrosive. Harmful if swallowed. May cause burns of the digestive system including
mouth, throat and stomach with severe abdominal pain and possible collapse.
Ingestion may cause death if not treated promptly. Ingestion has been linked
to cardiovascular effects in laboratory animals.
Skin Contact:
Corrosive. Contact can cause irritation with redness, pain, and possible skin
burns. Covered contact with wet clothing can cause severe skin burns. May be
absorbed through the skin.
Eye Contact:
Corrosive. Vapors irritate the eyes, causing tears, redness, pain, blurred
vision. Corneal edema may occur. Liquid contact will produce
serious eye injury, possibly blindness.
Chronic Exposure:
Repeated contact of eyes with vapors may result in swelling of the eyes and
blured vision. Chronic exposure may affect kidney and liver. Animal studies
have shown target organ effects on the heart.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders, eye problems, asthma, liver or kidney
disorders, or impaired respiratory function may be more sensitive to the
effects of the substance.
3. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing
is difficult, give oxygen. Call for medical help immediately.
Ingestion:
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything
by mouth to an unconscious person. Call a doctor immediately. If swallowed,
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything
by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Call for medical help immediately. Wash clothing
before reuse.
Eye Contact:
Flush eyes immediately with soft but strong stream of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Call for medical help
immediately.
4. Fire Fighting Measures
Fire:
Flash point: 134C
Autoignition temperature: 662C
Flammable limits in air % by volume:
lel: 1.8; uel: 10.1
Extremely Flammable. Contact with strong oxidizers may cause fire and explosions.
Explosion:
Above flash point, vapor-air mixtures are explosive (see flammable limits above).
Vapors can spread on surfaces to distant ignition source and flash back.
Sensitive to static discharge.
Fire Extinguishing Media:
Dry chemical, alcohol foam or carbon dioxide. Water may be ineffective. Use
water to cool fire-exposed containers, to dilute spills, to flush spills, and
to disperse vapors.
Special Information:
In the event of a fire, wear full protective clothing and self-contained
breathing apparatus with full facepiece. This highly flammable liquid must
be kept away from sparks, open flame, hot surfaces, and all sources of heat
and ignition. Fight fire from protected location
5. Accidental Release Measures
Ventilate area of leak or spill. Remove all
sources of ignition. Wear appropriate personal protective equipment
as specified in Section 7. Isolate exposed area. Contain and
recover liquid when possible. Use non-sparking tools and equipment.
Collect liquid in an appropriate container or absorb with an
inert material (e. g. dry sand), and place
in a chemical waste container. Do not use combustible materials,
such as saw dust. Do not flush to sewer! Use water spray to
keep vapor concentrations below explosive limits.
6. Handling and Storage
Protect against physical damage. Store in a
cool, dry well-ventilated location, away from any area where
the fire hazard may occur. Outside or detached storage is
preferred. Separate from incompatibles. Containers should be
bonded and grounded for transfers to avoid static sparks. Storage
and use areas should be No Smoking areas. Use non-sparking
type tools and equipment, including explosion proof ventilation.
Do not add nitrites or other nitrosating agents; a nitrosamine,
which may cause cancer, may be formed. Empty containers may
contain explosive vapors. Flush empty containers with water
to remove residual flammable liquid and vapors. 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.
7. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
25 ppm (TWA)
-ACGIH Threshold Limit Value (TLV):
5 ppm (TWA), 15 ppm (STEL), skin,
A4-not classifiable as a human carcinogen.
Ventilation System:
A system of local and/or general exhaust is recommended to keep 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.
Personal Respirators :
If the exposure limit is exceeded
a full facepiece respirator with an ammonia/methylamine cartridge may be
worn up to 50 times the exposure limit or the maximum use concentration
specified by the appropriate regulatory agency or respirator supplier,
whichever is lowest. For emergencies or instances where the exposure levels
are not known, use a full-facepiece positive-pressure, air-supplied respirator.
WARNING: Air purifying respirators do not protect in oxygen-deficient
atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat,
apron or overalls, 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 facilities in work
area.
8. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Burning may produce ammonia, carbon monoxide, carbon dioxide, nitrogen oxides.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Strong oxidizers, acids, cellulose nitrate, some metals and dicyanofuroxan.
N-nitrosamines, many of which are known to be potent carcinogens, may be formed
when this product comes in contact with nitrous acid, nitrates, or atmospheres
with high nitrous oxide concentrations.
Conditions to Avoid:
Heat, flames, ignition sources and incompatibles.

10. Ecological Information
Environmental Hazards:
When released into the air the material may be removed from the atmosphere
to a moderate extent by wet deposition. When released into the air, this
material is expected to be readily degraded by reaction with photochemically
produced hydroxyl radicals. This material is not expected to significantly
bioaccumulate. This material has an estimated bioconcentration factor (BCF)
of less than 100. When released into the water, this material is expected
to have a half-life between 1 and 10 days. When released into water, this
material is expected to readily biodegrade. When released into the soil,
this material may biodegrade to a moderate extent. When released into the
soil, this material may leach into groundwater. When released into the soil,
this material is expected to quickly evaporate.
