**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Very toxic by inhalation. Irritating to eyes, respiratory
system and skin. Toxic in contact with skin and if swallowed.Stench.
Potential Health Effects
Eye:
Causes severe eye irritation and possible burns. May cause
reversible inflammation and corneal injury with opacity.
Skin:
May be fatal if absorbed through the skin. Causes severe skin
irritation and possible burns. May cause severe dermatitis and
burns. Substance is readily absorbed through the skin. May cause
cyanosis of the extremities.
Ingestion:
May be fatal if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns. May form
methemoglobin which in sufficient concentration causes cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood).
Inhalation:
Inhalation may be fatal as a result of spasm, inflammation, edema of
the larynx and bronchi, chemical pneumonitis and pulmonary edema.
Inhalation may produce burning sensation, coughing, wheezing,
laryngitis, shortness of breath, headache, nausea, and vomiting.
Causes severe respiratory tract irritation with possible burns.
Inhalation at high concentrations may cause CNS depression and
asphixiation. Causes irritation of the mucous membrane.
Chronic:
Absorption into the body leads to the formation of methemoglobin
which in sufficient concentrations causes cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Prolonged exposure can injure liver, kidneys and lungs. This
substance has caused adverse reproductive and fetal effects in
laboratory animals.
**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. Do not use mouth-to-mouth resuscitation if victim
ingested or inhaled the substance; induce artificial respiration with
the aid of a pocket mask equipped with a one-way valve or other
proper respiratory medical device.
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. 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. Flammable liquid and
vapor. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas. Containers may explode
when heated. Runoff from fire control or dilution water may cause
pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. 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:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Cover with an activated carbon adsorbent and place
into a closed container for disposal. Remove all sources of ignition.
Use a spark-proof tool. 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. 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. Use only in a chemical fume hood. Discard contaminated
shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames.
Storage:
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. Use only under a
chemical fume hood. Use adequate general or local explosion-proof
ventilation to keep airborne levels to acceptable levels.
