**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation. Dangerous for the ozone layer.Dangerous for
the environment.
Potential Health Effects
Eye:
Causes severe eye irritation. May cause conjunctivitis.
Skin:
Causes moderate skin irritation. May cause skin sensitization, an
allergic reaction, which becomes evident upon re-exposure to this
material. Exposure may cause irritation characterized by redness,
dryness, and inflammation. May be absorbed through the skin.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause effects similar to those for inhalation
exposure. May cause central nervous system depression. Alcohol can
intensify effects.
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. Causes
irritation of the mucous membrane and upper respiratory tract.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. May cause fetal effects. Laboratory experiments have
resulted in mutagenic effects. Prolonged exposure may cause liver,
kidney, and heart damage.
**** 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
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.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. 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:
Causes cardiac sensitization to endogenous catelcholamines which may
lead to cardiac arrhythmias. Do NOT use adrenergic agents such as
epinephrine or pseudoepinephrine. Alcoholic beverage consumption may
enhance the toxic effects of this substance.
**** 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. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water fog, dry chemical, carbon dioxide, or regular foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Absorb spill using an absorbent, non-combustible
material such as earth, sand, or vermiculite. Do not use combustible
materials such as sawdust. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Avoid
breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin,
and clothing. Keep container tightly closed. Do not ingest or
inhale.
Storage:
Keep away from sources of ignition. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
in aluminum containers.
**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
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.
