**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Limited evidence of a carcinogenic affect.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May be absorbed through the skin. Causes irritation with burning
pain, itching, and redness. Prolonged exposure may result in skin
burns.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. 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
carboxyhemoglobinemia.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. May cause narcotic
effects in high concentration. Vapors may cause dizziness or
suffocation. May cause blood changes. Overexposure may cause an
increase in carboxyhemoglobin levels in the blood. Can produce
delayed pulmonary edema.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Prolonged or repeated skin contact may cause dermatitis. May cause
reproductive and fetal effects. Laboratory experiments have resulted
in mutagenic effects. Chronic exposure may cause lung, liver, and
pancreatic tumors. May cause conjunctivitis and/or corneal burns.
**** 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:
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:
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. Use water spray to keep fire-exposed containers
cool. No flash point in conventional closed tester, but forms
flammable vapor-air mixtures in larger volumes and may be an
explosion hazard in a confined space.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Avoid contact with heat, sparks and flame.
Use only with adequate ventilation. Avoid breathing vapor or mist.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Store below 40C. Keep away from active
metals.
**** 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 chemical goggles.
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.
