**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful in contact with skin and if swallowed. Toxic by inhalation.
Causes burns.Stench.Moisture sensitive.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May cause conjunctivitis and corneal
inflammation.
Skin:
Harmful if absorbed through the skin. Causes skin burns. If
absorbed, may cause central nervous system effects. If absorbed
through the skin, may cause depressed respiration, lowered body
temperature, nausea, salivation, diarrhea, dizziness, and diuresis.
May cause cyanosis of the extremities. May cause skin rash (in
milder cases), and cold and clammy skin with cyanosis or pale color.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns. May cause
liver damage. May cause perforation of the digestive tract. May cause
tissue anoxia, characterized by weakness, headache, dizziness,
confusion, cyanosis (bluish skin due to deficient oxygenation of the
blood), weak and irregular heart beat, collapse, unconsciousness,
convulsions, coma and death. May cause excessive salivation,
vomiting, and diarrhea. High concentrations may cause drowsiness,
convulsions, unconsciousness and central nervous system damage.
Inhalation:
May be fatal if inhaled. Causes chemical burns to the respiratory
tract. May cause effects similar to those described for ingestion.
Inhalation may be fatal as a result of spasm, inflammation, edema of
the larynx and bronchi, chemical pneumonitis and pulmonary edema.
May cause systemic effects. May cause burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Inhalation at high concentrations may cause CNS depression
and asphixiation.
Chronic:
Not available.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes 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
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do not use
mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
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. Combustible
liquid. Containers may explode when heated. Water hydrolyzes material
liberating acidic gas which in contact with metal surfaces can
generate flammable and/or explosive hydrogen gas.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Use foam, dry chemical, or carbon dioxide.
Do NOT get water inside containers.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Use a spark-proof
tool. Provide ventilation. Do not get water inside containers. Cover
with dry earth, dry sand, or other non-combustible material followed
with plastic sheet to minimize spreading and contact with water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Do not breathe
dust, vapor, mist, or gas. Do not get in eyes, on skin, or on
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. Do not ingest or inhale. Use and
store under nitrogen. Do not allow contact with water. Discard
contaminated shoes. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. 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. Store protected from
moisture.
**** 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
CAS# 2524-03-0:
Russia: 0.5 mg/m3 TWA
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.
