**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic if swallowed. Contact with combustible material may cause
fire.Oxidizer.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
irritation and/or dermatitis.
Ingestion:
Harmful if swallowed. Ingestion of large amounts may cause
gastrointestinal irritation. May cause methemoglobinemia, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), convulsions, and death.
Inhalation:
May cause respiratory tract irritation. May cause methemoglobinemia,
cyanosis, convulsions, tachycardia, dyspnea (labored breathing), and
death. May cause effects similar to those described for ingestion.
Chronic:
Absorption into the body leads to the formation of methemoglobin
which in sufficient concentrations causes cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
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:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid if cough or other symptoms appear.
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
methemoglobinemia 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. Oxidizer. Greatly
increases the burning rate of combustible materials. Containers may
explode in the heat of a fire. Some oxidizers may react explosively
with hydrocarbons(fuel).
Extinguishing Media:
Use flooding quantities of water. Cool containers with flooding
quantities of water until well after fire is out. For small fires,
do NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER
ONLY.
**** 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.
Flush spill area with water. Do not use combustible materials such as
paper towels to clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Keep away from reducing agents.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
