Composition, Information on Ingredients
Symbols: XI F
Risk Phrases: 11 36/37/38 43
Section 3 - Hazards
Appearance: colourless. Flash Point: 50 deg F.
Danger! Flammable liquid and vapor. Corrosive.
Light sensitive. Air sensitive. Heat sensitive. May form explosive peroxides.
Sensitizer. May cause severe eye and skin irritation with possible burns. May
cause respiratory and digestive tract irritation. May cause central nervous
system depression. May cause liver and kidney damage. May cause allergic
respiratory reaction. May cause allergic skin reaction. May cause reproductive
and fetal effects.
Target Organs: Kidneys, central nervous
Eye: Contact with eyes may cause
severe irritation, and possible eye burns. May cause eye injury.
Skin: May cause severe skin irritation. May cause skin
sensitization, an allergic reaction, which becomes evident upon re-exposure to
Ingestion: May cause central nervous system
depression, kidney damage, and liver damage. May cause gastrointestinal
irritation with nausea, vomiting and diarrhea. May cause allergic reaction.
Exposure may cause headache, anorexia, and irritability.
Inhalation: Inhalation of high concentrations may cause
central nervous system effects characterized by nausea, headache, dizziness,
unconsciousness and coma. May cause allergic respiratory reaction. May cause
respiratory tract irritation. May cause effects similar to those described for
Chronic: Prolonged or repeated skin contact may
cause sensitization dermatitis and possible destruction and/or ulceration. May
cause reproductive and fetal effects. Repeated exposure may cause tingling in
the extremities and other nervous system abnormalities.
Section 4 - First Aid
Eyes: Immediately flush eyes with plenty of water
for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get
medical aid immediately.
Skin: Get medical aid immediately.
Immediately flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: Do NOT induce vomiting. If victim is conscious
and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from
exposure 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.
Physician: No specific antidote exists. Treat symptomatically and
Section 5 - Fire
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. Flammable
Liquid. Can release vapors that form explosive mixtures at temperatures above
the flashpoint. Use water spray to keep fire-exposed containers cool. Vapor may
cause flash fire. Water may be ineffective. Material is lighter than water and a
fire may be spread by the use of water. May form explosive peroxides. Vapors may
be heavier than air. They can spread along the ground and collect in low or
confined areas. May polymerize explosively when involved in a fire. 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. 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
Information: Use proper personal protective equipment as indicated in
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. Provide ventilation.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Use with adequate ventilation.
Ground and bond containers when transferring material. Avoid contact with skin
and eyes. Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep container tightly closed. Avoid ingestion and inhalation.
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.
Storage: Keep away from
heat, sparks, and flame. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances. 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
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

Eyes: Wear appropriate protective
eyeglasses or chemical 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
Clothing: Wear appropriate protective clothing to
prevent skin exposure.
Respirators: Follow the OSHA respirator
regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator when necessary.
