**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation and in contact with skin. May cause harm to
the unborn child.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin. If
absorbed, causes symptoms similar to those of ingestion. Not
expected to cause an allergic skin reaction.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver damage. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to
respiratory failure.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. Inhalation at high concentrations may
cause CNS depression and asphixiation.
Chronic:
Chronic ingestion may cause liver damage. May cause reproductive and
fetal effects.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Containers may explode
when heated. Combustible liquid and vapor. Vapors are heavier than
air and may travel to a source of ignition and flash back. Vapors can
spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Discard contaminated
shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames. Use only
with adequate ventilation. Keep away from heat and flame. Avoid
breathing vapor or mist. Destroy contaminated leather clothing.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a tightly closed container. Keep under a nitrogen blanket.
Store in a cool, dry, well-ventilated area away from incompatible
substances.
**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
