**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful in contact with skin and if swallowed. Risk of serious
damage to eyes. May cause sensitization by skin contact. Very toxic
to aquatic organisms.
Potential Health Effects
Eye:
Contact may cause severe eye irritation and possible eye damage.
Risk of serious damage to eyes.
Skin:
Harmful if absorbed through the skin. 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.
Ingestion:
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. Causes gastrointestinal tract irritation.
Inhalation:
Causes respiratory tract irritation. May be harmful if inhaled.
Chronic:
May cause liver and kidney damage. Repeated skin contact may cause
dermatitis with dark pigmentation of the skin.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
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.
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.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam.
**** 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. Reduce airborne dust and prevent scattering by moistening
with water. 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. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Avoid contact with skin and eyes. Avoid ingestion and
inhalation.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
**** 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.
Exposure Limits

Netherlands: 3 mg/m3 MAC
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:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
