**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Causes
burns. Contact with combustible material may cause fire.Moisture
sensitive.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May cause permanent corneal opacification. May
cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May cause skin rash (in milder cases), and cold
and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. The toxicological properties of this substance have not been
fully investigated. May cause systemic effects. May cause nausea,
vomiting, and diarrhea, possibly with blood.
Inhalation:
Causes chemical burns to the respiratory tract. The toxicological
properties of this substance have not been fully investigated.
Aspiration may lead to pulmonary edema. May cause systemic effects.
May cause acute pulmonary edema, asphyxia, chemical pneumonitis, and
upper airway obstruction caused by edema.
Chronic:
Effects may be delayed.
**** 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 not breathing, give artificial respiration. 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:
**** 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. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Use water with
caution and in flooding amounts.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Do NOT get water
inside containers. Contact professional fire-fighters immediately.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** 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. Avoid generating dusty conditions. Remove all
sources of ignition. Provide ventilation. Do not get water inside
containers. Do not use combustible materials such as paper towels to
clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid contact with
clothing and other combustible materials. Avoid ingestion and
inhalation. Do not allow contact with water. Discard contaminated
shoes. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a tightly closed container. Store in
a cool, dry, well-ventilated area away from incompatible substances.
Corrosives area. Store protected from moisture.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 25979-07-1:
Personal Protective Equipment
Eyes:

safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear a chemical apron. Wear appropriate protective
clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
