Potential Health Effects
----------------------------------
Depending on the intensity and duration of exposure, health effects may vary
from mild irritation to severe destruction of tissue.
Inhalation:
Corrosive. Inhalation causes irritation of the nose, throat, and respiratory
system. Symptoms may include coughing, sore throat, labored breathing. Seri
ous cases may be fatal. May cause allergic reaction in sensitive individuals
.
Ingestion:
Corrosive. Harmful if swallowed. Sore throat, abdominal pain, vomiting, and
diarrhea may occur.
Skin Contact:
Corrosive. Toxic. Causes severe irritation with redness, pain, possibly burn
s. May be absorbed through the skin. May cause allergic reaction in sensitiv
e individuals.
Eye Contact:
Corrosive. Vapors irritate the eyes. Liquid causes burns.
Chronic Exposure:
Exposure may cause an allergic skin and respiratory reaction in some individ
uals. Liver, kidneys and lungs may be damaged from repeated exposure.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver,
kidney or respiratory function may be more susceptible to the effects of th
e substance.
----------------------------------------------------------------------------

4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breat
hing 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 re
moving 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 imm
ediately.

5. Fire Fighting Measures
Fire:
Flash point: 40C (104F) CC
Autoignition temperature: 385C (725F)
Flammable limits in air % by volume:
lel: 2.5; uel: 12.0
Flammable Liquid
( uel @100C )
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Vapors can flow along surfaces to distant ignition source and f
lash back. Sensitive to static discharge.
Fire Extinguishing Media:
Dry chemical, alcohol foam or carbon dioxide. Use water spray to cool fire-e
xposed containers, to dilute liquid, and control vapor.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved sel
f-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 approp
riate personal protective equipment as specified in Section 8. Isolate hazar
d area. Keep unnecessary and unprotected personnel from entering. Contain an
d recover liquid when possible. Use non-sparking tools and equipment. Collec
t 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.
----------------------------------------------------------------------------
----
7. Handling and Storage
Protect against physical damage. Store in a cool, dry well-ventilated locati
on, away from any area where the fire hazard may be acute. Outside or detach
ed storage is preferred. Separate from incompatibles. Containers should be b
onded and grounded for transfers to avoid static sparks. Storage and use are
as should be No Smoking areas. Use non-sparking type tools and equipment, in
cluding explosion proof ventilation. Containers of this material may be haza
rdous when empty since they retain product residues (vapors, liquid); observ
e 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): 10 ppm (TWA) skin,
A4 - Not classifiable as a human carcinogen.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exp
osures below the Airborne Exposure Limits. Local exhaust ventilation is gene
rally preferred because it can control the emissions of the contaminant at i
ts source, preventing dispersion of it into the general work area. Please re
fer to the ACGIH document, Industrial Ventilation, A Manual of Recommended P
ractices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible,
a full facepiece respirator with organic vapor cartridge may be worn up to
50 times the exposure limit or the maximum use concentration specified by th
e 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 pur
ifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apro
n or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is pos
sible. Maintain eye wash fountain and quick-drench facilities in work area.
