**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful by inhalation and if swallowed.Light
sensitive.Air sensitive.Flammable liquid.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Methemoglobinemia is characterized by dizziness,
drowsiness, headache, breath shortness, cyanosis with bluish skin,
rapid heart rate and chocolate-brown colored blood.
Inhalation:
May cause respiratory tract irritation. May cause dizziness,
incoordination, and unconsciousness. Methemoglobinemia is
characterized by dizziness, drowsiness, headache, breath shortness,
cyanosis with bluish skin, rapid heart rate and chocolate-brown
blood.
Chronic:
May cause methemoglobinemia, which is characterized by
chocolate-brown colored blood, headache, weakness, dizziness, breath
shortness, cyanosis (bluish skin due to deficient oxygenation of
blood), rapid heart rate, unconsciousness and possible death.
**** 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:
Immediately flush skin with plenty of soap and water for at least 15
minutes while removing contaminated clothing and shoes. Get medical
aid if irritation develops or persists. 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 immediately.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
blue depending on the methemoglobinemia concentration in the blood.
Antidote:
Methylene blue, alone or in combination with oxygen is indicated as
a treatment in nitrite induced methemoglobinemia.
**** 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. 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. May polymerize explosively when involved in a fire.
May be ignited by heat, sparks, and flame. Containers may explode
when heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. For large fires, use water
spray, fog or alcohol-resistant foam. 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:
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. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal. Remove all sources of ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with skin and eyes. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Avoid ingestion and
inhalation. Avoid contact with air and sunlight. 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 cool place in the
original container and protect from sunlight. Store in a tightly
closed container. Keep under a nitrogen blanket. Flammables-area.
Store protected from light and air.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local explosion-proof ventilation to keep
airborne levels to acceptable levels.
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 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
