EMERGENCY OVERVIEW
Appearance: almost white to brown solid.
Warning! Causes eye and skin burns. Harmful if
absorbed through the skin. Harmful if swallowed. May cause allergic
skin reaction. May cause severe respiratory and digestive tract
irritation with possible burns. May cause central nervous system
depression. May cause methemoglobinemia. Sublimes (goes directly
from solid to vapor form) readily at room temperature.
Target Organs: Kidneys, central nervous system,
liver, lungs, cardiovascular system, red blood cells.
Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Harmful if absorbed through the skin. Causes skin burns. Prolonged
and/or repeated contact may cause irritation and/or dermatitis. May
cause skin sensitization, an allergic reaction, which becomes evident
upon re-exposure to this material. If absorbed, causes symptoms
similar to those of ingestion. May cause skin rash (in milder cases),
and cold and clammy skin with cyanosis or pale color.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal irritation with nausea,
vomiting and diarrhea. May cause perforation of the digestive tract.
May cause methemoglobinemia, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), convulsions, and death.
May cause central nervous system depression. May cause systemic
effects.
May cause a prolonged rise in blood pressure which may lead to
degenerative changes in the
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. May cause effects similar
to those described for ingestion. Aspiration may lead to pulmonary
edema. May cause systemic effects.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. 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 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 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.
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. Contact with metals may
evolve flammable hydrogen gas. Containers may explode when heated.
Non-combustible, substance itself does not burn but may decompose
upon heating to produce irritating, corrosive and/or toxic fumes.
Extinguishing Media:
Do NOT get water inside containers. For small fires, use dry
chemical, carbon dioxide, or water spray. For large fires, use dry
chemical, carbon dioxide, alcohol-resistant foam, or water spray.
Cool containers with flooding quantities of water until well after
fire is out.
Flash Point: 127 deg C ( 260.60 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. 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. Minimize dust
generation and accumulation. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Discard contaminated shoes.
Storage:
Keep container closed when not in use. Keep from contact with
oxidizing materials. Corrosives area. Store in a cool, dry area away
from incompatible substances.
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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
