**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Contact with acids liberates toxic gas. Causes
burns. May cause sensitization by inhalation.Corrosive.Air sensitive.
Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May cause skin rash (in milder cases), and cold
and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. 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. Overexposure may cause
methemoglobinemia. May cause systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects. May cause
respiratory sensitization.
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. Effects
may be delayed.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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 and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
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.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use alcohol foam, carbon dioxide, or water spray when fighting fires
involving this material.
**** 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 or absorb material, then place into a
suitable clean, dry, closed container for disposal. Flush spill area
with water. Provide ventilation. Place under an inert atmosphere.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Use with
adequate ventilation. Avoid contact with skin and eyes. Do not
breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or
on clothing. Keep container tightly closed. Avoid ingestion and
inhalation. Do not ingest or inhale. Handle under an inert
atmosphere. Store protected from air. Discard contaminated shoes.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
Keep away from water. Keep containers tightly closed. Do not expose
to air. Store under an inert atmosphere.
**** 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
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7080-50-4:
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:
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 respirator use.
