**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Danger of cumulative
effects. Irritating to eyes, respiratory system and skin.Air
sensitive.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. May cause skin sensitization, an allergic reaction, which
becomes evident upon re-exposure to this material. Prolonged and/or
repeated contact may cause defatting of the skin and dermatitis.
Ingestion:
May cause liver and kidney damage. May cause headache. May cause
nausea and vomiting. May cause central nervous system depression. May
cause thyroid abnormalities. May be harmful if swallowed. Chronic
ingestion of iodides during pregnancy has resulted in fetal death,
severe goiter, and cretinoid appearance of the newborn.
Inhalation:
May cause allergic respiratory reaction. May cause irritation of the
respiratory tract with burning pain in the nose and throat, coughing,
wheezing, shortness of breath and pulmonary edema. May cause narcotic
effects in high concentration.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. Prolonged or repeated exposure may cause adverse
reproductive effects. Chronic exposure can lead to iodism
characterized by salivation, nasal discharge, sneezing,
conjunctivitis, fever, laryngitis, bronchitis, stomatitis, and skin
rashes. Repeated or prolonged exposure may cause allergic reactions
in sensitive individuals.
**** 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 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:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. 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. Vapors can travel to a source of ignition and flash
back. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Will burn if
involved in a fire. Use water spray to keep fire-exposed containers
cool. Extremely flammable liquid and vapor. Water may be
ineffective. Material is lighter than water and a fire may be spread
by the use of water. Vapors may be heavier than air. They can
spread along the ground and collect in low or confined areas.
Containers may explode when heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water may be ineffective. Do NOT get water
inside containers. For large fires, use water spray, fog or
alcohol-resistant foam. Do NOT use straight streams of water. Cool
containers with flooding quantities of water until well after fire
is out.
**** 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. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal. Remove all sources of ignition. Use a spark-proof tool.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid breathing
dust, vapor, mist, or gas. Do not get in eyes, on skin, or on
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Do not
ingest or inhale. Use only in a chemical fume hood. If peroxide
formation is suspected, do not open or move container. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Do not distill since this
removes peroxide-inhibitors.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep under an argon blanket. Refrigerator/flammables.
After opening, purge container with nitrogen before reclosing.
Periodically test for peroxide formation on long-term storage.
Addition of water or appropriate reducing materials will lessen
peroxide formation.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
