**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to skin. Harmful : danger of serious
damage to health by prolonged exposure through inhalation. Possible
risk of impaired fertility. Toxic to aquatic organisms; may cause
long-term adverse effects in the aquatic environment. Harmful: may
cause lung damage if swallowed. Vapors may cause drowsiness and
dizziness.Dangerous for the environment.
Potential Health Effects
Eye:
Causes mild eye irritation. Causes redness and pain. May cause
blurred vision, tearing, and conjunctivitis.
Skin:
Prolonged and/or repeated contact may cause defatting of the skin
and dermatitis. Causes irritation with burning pain, itching, and
redness. Absorbed through the skin.
Ingestion:
Aspiration hazard. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea. Aspiration of material into the lungs
may cause chemical pneumonitis, which may be fatal. May cause central
nervous system effects. Aspiration can cause asphyxia, brain damage,
and cardiac arrest.
Inhalation:
Causes respiratory tract irritation. Exposure produces central
nervous system depression. Aspiration may cause respiratory swelling
and pneumonitis. Inhalation of high concentrations may cause
narcotic effects. Vapors may cause dizziness or suffocation. Exposure
may cause vertigo, hallucinations, fatigue, muscle weakness, visual
disturbances, nervous system disturbances, coughing, chest pains,
difficulty in breathing, lung irritation, gastrointestinal
disturbances, and edema which may be fatal.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. Prolonged or repeated exposure may cause adverse
reproductive effects. May cause fetal effects. Chronic exposure may
cause visual disturbances. Laboratory experiments have resulted in
mutagenic effects. Peripheral neuropathy symptoms include: muscular
weakness, paresthesia, numbing of the hands, feet, legs and arms,
unsteadiness, and difficulty in walking and standing. Repeated
exposure may cause nervous system abnormalities with muscle weakness
and damage, motor incoordination, and sensation disturbances.
Chronic exposure produces peripheral neuropathy.
**** 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.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
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:
Treat symptomatically and supportively. For ingestion, the stomach
sould be intubated, aspirated, and lavaged with a slurry of activated
charcoal--protect the airway from aspiration of gastric contents.
Monitor arterial blood gases in cases of severe aspiration.
**** 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.
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. 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. May accumulate static electrical
charges, and may cause ignition of its own vapors. Containers may
explode if exposed to fire. 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.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water may be ineffective. Water may spread
fire. If water is the only media available, use in flooding amounts.
For large fires, use water spray, fog or alcohol-resistant foam. Do
NOT use straight streams of water. Contact professional
fire-fighters immediately. 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. Provide ventilation. A vapor suppressing foam
may be used to reduce vapors. Use only non-sparking tools and
equipment.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Take precautionary measures against static discharges.
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 and flame. Keep away from sources of ignition.
Store in a tightly closed container. Keep from contact with oxidizing
materials. 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. 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:
Wear appropriate protective gloves to prevent skin
exposure.
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.
