**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Extremely flammable. Irritating to eyes and respiratory system.
Limited evidence of a carcinogenic effect.Lachrymator (substance
which increases the flow of tears).
Potential Health Effects
Eye:
Causes severe eye irritation. Vapors may cause eye irritation.
May cause transient corneal injury. Lachrymator (substance which
increases the flow of tears).
Skin:
May cause skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. May cause central nervous
system depression.
Inhalation:
Causes respiratory tract irritation. May cause narcotic effects in
high concentration. Exposure produces central nervous system
depression. Vapors may cause dizziness or suffocation. Can produce
delayed pulmonary edema. Inhalation of large amounts may cause
respiratory stimulation, followed by respiratory depression,
convulsions and possible death due to respiratory paralysis.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated eye contact may cause conjunctivitis. Prolonged skin
contact may cause erythema (redness) and burns. Long-term inhalation
studies of acetaldehyde produced laryngeal cancers in hamsters and
nasal cancers in rats.
**** 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 immediately.
Skin:
In case of contact, immediately flush skin with soap and plenty of
water. Remove contaminated clothing and shoes. Get medical aid if
symptoms occur. 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:
Persons with kidney disease, chronic respiratory disease, liver
disease, or skin disease may be at increased risk from exposure to
this substance. Treat symptomatically and supportively.
Antidote:
None reported.
**** 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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. Vapors may form an explosive
mixture with air. Use water spray to keep fire-exposed containers
cool. Wear appropriate protective clothing to prevent contact with
skin and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products. Extremely
flammable liquid and vapor. Vapor may cause flash fire. Forms
peroxides of unknown stability. Containers may explode in the heat of
a fire. Will be easily ignited by heat, sparks or flame. 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. Sensitivity to mechanical impact: Yes, if peroxides
are formed. Closed containers exposed to heat may explode. Sensitive
to static discharge.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Water may be ineffective. Do NOT use
straight streams of water.
**** 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. Use water spray to dilute spill to
a non-flammable mixture. Avoid runoff into storm sewers and ditches
which lead to waterways. Use water spray to disperse the gas/vapor.
Remove all sources of ignition. Use a spark-proof tool. Provide
ventilation. Place under an inert atmosphere. U.S. regulations
require reporting spills and releases to soil, water and air in
excess of reportable quantities.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Ground and bond containers when transferring material. Do not
breathe 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. Take precautionary measures against
static discharges. Keep container tightly closed. Keep away from
heat, sparks and flame. Do not ingest or inhale. Handle under an
inert atmosphere. Store protected from air. This product may be
under pressure; cool before opening. 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. Use only with adequate ventilation.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Keep from freezing. Store in a tightly closed container.
Keep from contact with oxidizing materials. Keep away from strong
acids. Refrigerator/flammables. Keep away from reducing agents. Do
not expose to air. Store in explosion-proof refrigerator. 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. Store under an inert atmosphere.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. 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.
Exposure Limits
CAS# 1632-89-9:
Personal Protective Equipment
Eyes:
Wear chemical splash goggles.

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.
