**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Contact with water liberates extremely flammable
gases.Corrosive.Water-reactive.
Potential Health Effects
Eye:
Causes severe eye burns. May cause blindness. May cause opacity
and scarring.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
May cause severe irritation of the upper respiratory tract with
pain, burns, and inflammation. Can produce delayed pulmonary edema.
Chronic:
Repeated inhalation may cause chronic bronchitis.
**** 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. Destroy contaminated shoes.
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:
Wear appropriate protective clothing to prevent contact with skin
and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products. Contact with
moisture or water may generate sufficient heat to ignite nearby
combustible materials. Contact with moisture to form flammable
acetylene gas. Contact with acid or acid fumes evolves heat and
flammable vapors.
Extinguishing Media:
Do NOT use carbon dioxide. Do NOT use halogenated agents. Use
approved class D extinguishing agents or smother with dry sand,
clay, or sodium bicarbonate. DO NOT USE WATER! Use dry chemical.
**** 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.
Remove all sources of ignition. Use a spark-proof tool. Do not expose
spill to water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Ground and bond containers
when transferring material. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale.
Storage:
Keep away from sources of ignition. 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 water. Keep containers tightly closed. Store in metal
containers.
**** 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.
Exposure Limits
CAS# 75-20-7:
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 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.

with water to form highly flammable acetylene gas, which may ignite
spontaneously. Lime may also be formed raising the pH of the
solution and causing a white precipitate.
Conditions to Avoid:
Incompatible materials, contact with water, acids, exposure to moist
air or water, oxidizers.
Incompatibilities with Other Materials:
Incompatible with water, hydrogen chloride, lead fluoride, magnesium,
selenium, silver nitrate, sulfur, silver nitrate, sodium peroxide,
stannous chloride, potassium hydroxide and chlorine.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, calcium oxide.
Hazardous Polymerization: Has not been reported.
