| 3. HAZARD INDENTIFICATION |
* * * EMERGENCY OVERVIEW * * *
Poisonous, corrosive high pressure liquid and gas.
May cause liver damage.
Can cause eye, skin, and respiratory tract burns.
POTENTIAL HEALTH EFFECTS
ROUTES OF ENTRY: Inhalation, Skin
ACUTE EFFECTS: Inhalation of vapors may cause pulmonary edema, circulatory collapse, damage to upper respiratory tract, coughing, difficulty breathing and choking.It is severly irritating and corrosive to the eyes, mucous membranes and upper respiratory tract.Contact with liquid can cause severe burns of skin and eyes.
CHRONIC EFFECTS: None known
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: None known
OTHER EFFECTS OF OVEREXPORSURE: None
CARCINOGENICITY (US ONLY):
NTP - No
IARC MONOGRAPHS - No
OSHA REGULATED - No
INHALATION: Immediately remove victim to fresh air.If breathing has stopped, give artificial respiration.If breathing is difficult, give oxygen.
EYE CONTACT: Flush with large amounts of water lifting upper and lower lids.
SKIN CONTACT: Rinse the affected area with flooding amounts of water and then wash it with soap and water.
INGESTION: None
IN EVENT OF EXPOSURE, CONSULT A PHYSICIAN
NOTE TO PHYSICIAN: Treat respiratory effects following inhalation of hydrogen chloride using a 5% sodium bicarbonate solution in aerosol.Maintain proper fluid balance and decrease the inflammation by administering steroids on a short-term basis (2 to 4 days).
| 5. FIRE FIGHTING MEASURES |
FLASH POINT: Nonflammable
AUTOIGNITION TEMPERATURE: N/Ap
FLAMMABLE LIMITS: Nonflammable
EXTINGUISHING MEDIA: Use what is appropriate for surrounding fire.
SPECIAL FIRE FIGHTING INSTRUCTION AND EQUIPMENT: Wear self-contained breathing apparatus and full protective clothing.Remove cylinders or cool with water spray to prevent release of HCl.Special neutralization procedures, if applicable, include the application of chemically basic substances.
HAZARDOUS COMBUSTION PRODUCTS: None
UNUSUAL FIRE AND EXPLOSION HAZARDS: May emit hydrogen gas upon contact with metal.Contact with water causes formation of dense hydrochloric acid fumes.
| 6. ACCIDENTAL RELEASE MEASURES |
CLEAN UP PROCEDURES: Evacuate and ventilate area.Remove leaking cylinder to exhaust hood or safe outdoor area.Shut off source if possible and remove source of heat.Place waste into a clean, dry container for disposal.
SPECIALIZED EQUIPMENT: Small leaks can be detected with concentrated NH4OH by giving off white fumes.Neutralize spills with soda ash or lime.
PRECAUTIONS TO BE TAKEN IN HANDLING: Secure cylinder when using to protect from falling.Use suitable hand truck to move cylinders.
PRECAUTIONS TO BE TAKEN IN STORAGE: Store in well ventilated areas.Store away from heat, flame, and sparks.Keep valve protection cap on cylinders when not in use.No part of cylinder should be exposed to temperatures above 52 degrees celsius.
| 8. EXPOSURE CONTROLS / PERSONAL PROTECTION |
ENGINEERING CONTROLS: Provide adequate general and local exhaust ventilation to maintain concentration below exposure limits.
EYE / FACE PROTECTION: Safety glasses
SKIN PROTECTION: Impervious gloves, coveralls, boots, and/or other resistant protective clothing.
RESPIRATORY PROTECTION: In case of leakage, use self-contained breathing apparatus.
OTHER PROTECTIVE EQUIPMENT: Safety shoes when handling cylinders.

TERATOGENICITY: N/Ap
REPRODUCTIVE EFFECTS: N/Ap
MUTAGENICITY: N/Ap
| 12. ECOLOGICAL INFORMATION |
No adverse ecological effects are expected.
| 13. DISPOSAL CONSIDERATIONS |
WASTE DISPOSAL METHOD: Dispose of non-refillable cylinders in accordance with federal, state and local regulations. Allow gas to vent slowly to atmosphere in an unconfined area or exhaust hood. If the cylinders are the refillable type, return cylinders to supplier with any valve outlet plugs or caps secured and valve protection caps in place.Can be neutralized with sodium hydroxide or other suitable alkali.Neutral salt solution can usually be flushed to the sewer with high dilution.
