**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Irritating to respiratory system. Toxic to aquatic
organisms; may cause long-term adverse effects in the aquatic
environment. Harmful: may cause lung damage if swallowed.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis.
Skin:
Causes skin irritation. Exposure may cause irritation characterized
by redness, dryness, and inflammation.
Ingestion:
Aspiration hazard. Causes gastrointestinal irritation with nausea,
vomiting and diarrhea. Aspiration of material into the lungs may
cause chemical pneumonitis, which may be fatal. May be harmful if
swallowed.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause narcotic effects in high concentration. Vapors
may cause dizziness or suffocation. Causes irritation of the mucous
membrane and upper respiratory tract.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation may cause effects similar to those of acute inhalation.
Repeated exposure may cause damage to the spleen. Prolonged exposure
can injure liver, kidneys and lungs.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. 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. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. 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:
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.
**** 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. Water may be ineffective.
Material is lighter than water and a fire may be spread by the use of
water. Flammable 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. May accumulate
static electricity.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water may be ineffective. This material is
lighter than water and insoluble in water. The fire could easily be
spread by the use of water in an area where the water cannot be
contained. For large fires, use water spray, fog or alcohol-resistant
foam. 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid contact with
eyes, skin, and clothing. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Keep container tightly
closed. Avoid contact with heat, sparks and flame. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Use only with adequate
ventilation. Avoid breathing vapor or mist.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. Containers should be dated when opened and tested
periodically for the presence of peroxides. Should crystals form in
a peroxidizable liquid, peroxidation may have occurred and the
product should be considered extremely dangerous. In this instance,
the container should only be opened remotely by professionals.
Isolate from oxidizing materials and acids. All peroxidizable
substances should be stored away from heat and light and be
protected from ignition sources.
**** 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 explosion-proof ventilation to keep airborne levels to
acceptable levels.
Personal Protective Equipment
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:
Use polyvinyl alcohol or fluorocarbon rubber (viton)
gloves.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR ??1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
