**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if
swallowed.Stench.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May cause skin irritation. May be harmful if absorbed through the
skin. Effects may be delayed. May cause smarting of the skin and
first-degree burns on short exposure.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver and kidney 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. May cause effects similar to those for
inhalation exposure. Effects may be delayed.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause respiratory tract irritation. Prolonged exposure
may result in dizziness and general weakness.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation and ingestion may cause effects similar to those of acute
inhalation and ingestion. May cause liver and kidney damage.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
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. Flush skin with plenty of 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:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
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 may form an explosive mixture with air.
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. Water may be ineffective. Material is
lighter than water and a fire may be spread by the use of water.
Containers may explode in the heat of a fire. Flammable liquid and
vapor. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas.
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. 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. 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:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Ground and
bond containers when transferring material. 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. Keep away from heat, sparks and flame. Do not ingest or
inhale. 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 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.
**** 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. Ventilation fans and
other electrical service must be non-sparking and have an
explosion-proof design.
Exposure Limits
CAS# 7291-22-7:
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:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
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.
