**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. Contact with combustible material may cause fire. Very
toxic to aquatic organisms; may cause long-term adverse effects in
the aquatic environment.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May be absorbed through the skin.
Ingestion:
Causes gastrointestinal tract burns. May cause systemic effects.
Inhalation:
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma. May cause systemic
effects.
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. Chronic
inhalation or ingestion may cause argyria characterized by blue-gray
discoloration of the eyes, skin and mucous membrances. Chronic skin
contact may cause permanent discoloration of the skin.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub 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
soap and 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 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:
**** 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. Strong oxidizer. Contact with combustible materials
may cause a fire. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Wear
appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** 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. Do not use
combustible materials such as paper towels to clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Minimize dust generation and
accumulation. Do not get in eyes, on skin, or on clothing. Keep
container tightly closed. Do not ingest or inhale. Use with adequate
ventilation. Do not store near combustible materials. Discard
contaminated shoes.
Storage:
Keep away from sources of ignition. Do not store near combustible
materials. Keep container closed when not in use. Store in a tightly
closed container. Store in a cool, dry, well-ventilated area away
from incompatible substances. Corrosives 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 adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
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 a respirator's use.
