**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed.Stench.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.
May cause cyanosis of the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. May be harmful if inhaled. Can
produce delayed pulmonary edema. Inhalation at high concentrations
may cause CNS depression and asphixiation.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Effects may
be delayed.
**** 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.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas. Containers may explode when heated.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. 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. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Avoid
ingestion and inhalation. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. 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 explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate ventilation to keep airborne
concentrations low.
Exposure Limits
CAS# 629-45-8:
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 respirator use.
