**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Danger of cumulative effects.
Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. If absorbed, may cause symptoms similar to those for
ingestion.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
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
methemoglobinemia, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), convulsions, and death.
Methemoglobinemia is characterized by dizziness, drowsiness,
headache, shortness of breath, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood.
Inhalation:
May cause respiratory tract irritation. May cause effects similar to
those described for ingestion. May cause drowsiness, unconsciousness,
and central nervous system depression.
Chronic:
No information found.
**** 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 immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse. Remove contaminated clothing and shoes.
Ingestion:
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 and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:
Absorption of this product into the body may cause cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive
measures: bed rest and oxygen inhalation. For methemoglobinemia,
administer oxygen alone or with Methylene Blue depending on the
methemoglobin concentration in the blood. Cleansing of the entire
contaminated area of the body is of utmost importance.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Evacuate area and fight fire from a safe distance. As in any fire,
wear a self-contained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full protective gear.
Combustion generates toxic fumes. Combustible material; even though
it may take some effort to ignite.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and 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. Wash
clothing before reuse. 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. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 554-84-7:
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.
