**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation and in contact with skin. Toxic if swallowed.
Irritating to eyes. Limited evidence of a carcinogenic effect. May
cause sensitization by skin contact. Very toxic to aquatic organisms,
may cause long-term adverse effects in the aquatic
environment.Possible risk of irreversible effects.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts. May cause skin sensitization, an allergic reaction,
which becomes evident upon re-exposure to this material.
Ingestion:
May cause irritation of the digestive tract. May cause liver and
kidney damage. 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. May be harmful if
swallowed. Overexposure may cause methemoglobinemia.
Inhalation:
Dust is irritating to the respiratory 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
blood. Inhalation of aniline causes anoxia due to the formation of
methemoglobin.
Chronic:
Chronic ingestion may cause liver damage. Prolonged or repeated skin
contact may cause dermatitis. 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:
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 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. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid if cough or other symptoms
appear. Do NOT use mouth-to-mouth resuscitation.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin 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. 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. Containers may explode
when heated. Combustible material; may burn but does not ignite
readily.
Extinguishing Media:
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.
**** 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. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Minimize dust generation and
accumulation. Avoid contact with skin and eyes. Keep container
tightly closed. Avoid ingestion and inhalation. Use with adequate
ventilation. Wash clothing before reuse.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
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 a chemical apron. Wear appropriate clothing to
prevent skin exposure.
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.
