Hazards Identification
Emergency Overview
--------------------------
DANGER! EXTREMELY FLAMMABLE LIQUID AND VAPOR. VAPOR MAY CAUSE
FLASH FIRE. HARMFUL IF SWALLOWED, INHALED OR ABSORBED THROUGH
SKIN. CAUSES BURNS TO ANY AREA OF CONTACT.
Potential
Health Effects
----------------------------------
Inhalation:
Inhalation produces damaging effects on the mucous membranes and
upper respiratory tract. Symptoms may include irritation of the
nose and throat, and labored breathing. May cause lung edema,
a medical emergency.
Ingestion:
Corrosive. Swallowing can cause severe burns of the mouth, throat,
and stomach. Can cause sore throat, vomiting, diarrhea.
Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur.
May be absorbed through the skin causing nausea, headache and
general discomfort.
Eye Contact:
Vapors are highly irritating and can cause corneal damage. Contact
with liquid can cause severe burns and blindness.
Chronic Exposure:
Chronic exposure may cause dermatitis, conjunctivitis, and lung
problems.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired
respiratory function may be more susceptible to the effects of
the 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:
DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Call a physician
immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Call a physician,
immediately. Wash clothing before reuse.
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:
Flash point: -18C (0F)
Autoignition temperature: 430C (806F)
Flammable limits in air % by volume:
lel: 2.8; uel: 14.4
Extremely Flammable Liquid.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable
limits noted above. Vapors can flow along surfaces to distant
ignition source and flash back. Sensitive to static discharge.
Fire Extinguishing Media:
Stop flow before extinguishing fire. Dry chemical, alcohol foam
or carbon dioxide. Water spray may be used to keep fire exposed
containers cool.
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. Remove all sources of ignition.
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.
Use non-sparking tools and equipment. 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! Use water spray to reduce vapors and dilute spills to
nonflammable mixtures.
7. Handling and Storage
Protect against physical damage. Store in a cool, dry well-ventilated
location, away from any area where the fire hazard may be acute.
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. 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 (PEL): 10 ppm (TWA)
-ACGIH Threshold Limit Value (TLV):
5 ppm (TWA), 15 ppm (STEL)
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 and engineering controls are
not feasible, a half-face respirator with an ammonia/methylamine
cartridge may be worn for up to ten times the exposure limit or
the maximum use concentration specified by the appropriate regulatory
agency or respirator supplier, whichever is lowest. A full-face
piece 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 workers in oxygen-deficient atmospheres. The recommended
cartridge is not specifically approved for this substance. Organic
vapor cartridges have a service life of less than 30 minutes with
this material.
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.
