**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful by inhalation and if swallowed.Hygroscopic
(absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May cause dermatitis. May cause cyanosis of
the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. 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. Ingestion of
large amounts may cause CNS depression. May be harmful if swallowed.
May form methemoglobin which in sufficient concentration causes
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood).
Inhalation:
Causes respiratory tract irritation. Aspiration may lead to
pulmonary edema. Vapors may cause dizziness or suffocation. May
cause burning sensation in the chest.
Chronic:
Effects may be delayed.
**** 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.
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. If breathing is difficult, give oxygen. 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. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Will burn if involved in a fire. Use
water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. Flammable liquid and vapor. May
explode when heated.
Extinguishing Media:
Use alcohol foam, carbon dioxide, or water spray when fighting fires
involving this material. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use dry chemical. Do NOT
use straight streams of water.
**** 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.
Cover with sand, dry lime or soda ash and place in a closed
container for disposal. Remove all sources of ignition. Use a
spark-proof tool. Provide ventilation. A vapor suppressing foam may
be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
away from heat, sparks and flame. Avoid ingestion and inhalation.
Use only in a chemical fume hood. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Store protected from
moisture.
**** 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.
