SECTION III - PHYSICAL DATA

BOILING POINT  (F): 182 SPECIFIC GRAVITY:  1.16
VAPOR PRESSURE (mm Hg): Unknown % VOLATILE, BY VOLUME: 100%
VAPOR DENSITY (air=1): 1.268 EVAPORATION RATE: Similar to water
SOLUBILITY IN WATER: Complete APPEARANCE AND ODOR: Clear, colorless to slightly yellow liquid with a pungent odor.
SECTION IV - FIRE AND EXPLOSION DATA
FLASH POINT: Nonflammable
FLAMMABLE LIMITS:
             Lel:       N/A            Uel:     N/A
EXTINGUISHING MEDIA:
             Water spray, dry chemicals, foam or carbon dioxide.
SPECIAL FIRE-FIGHTING PROCEDURES:
             When heated, hydrochloric acid releases hydrogen chloride gas. Use a self-contained respirator if heating
             occurs.
UNUSUAL FIRE-FIGHTING AND EXPLOSION HAZARDS:
              Hydrochloric acid reacts with steel and many common metals to produce hydrogen gas, which is highly
              flammable and a fire and explosion hazard.

 

SECTION V - REACTIVITY DATA
STABILITY: Stable

HAZARDOUS POLYMERIZATION: Will not occur.

CONDITIONS OR MATERIALS TO AVOID:

              Avoid contact with metals and sulfides. Contact with metals produces flammable or explosive hydrogen.
              Contact with metals releases poisonous hydrogen sulfide gas. Avoid contact with bases or any other
              chemicals.
HAZARDOUS DECOMPOSITION PRODUCTS:
              Hydrochloric acid is stable; however, highly corrosive hydrogen chloride gas and hydrochloric acid vapor is
              released at above boiling temperatures.

SECTION VI - HEALTH HAZARD DATA

CARCINOGENIC LISTING:
              NTP: No ingredients listed in this section.
              IARC MONOGRAPHS: No ingredients listed in this section.
              OSHA 29 CFR 1910: No ingredients listed in this section.

ENTRY ROUTES & EFFECTS OF OVEREXPOSURE:

              Contact:             Can cause severe burns to eyes, skin and mucous membranes.

              Inhalation:         Vapor can cause severe irritation or burns to respiratory tract.

              Ingestion:           Can cause severe burns to the gastrointestinal system, which could result in death.

STATEMENT OF PRACTICAL TREATMENT:

               Contact:              Immediately flush exposed area thoroughly with water for at least 15 minutes while
                                           removing contaminated clothing and shoes. Consult a physician. For eyes, flush with large
                                           amounts of cool water for at least 15 minutes. Get medical attention immediately.

 

               Inhalation:          Remove to fresh air. If not breathing, begin artificial respiration. If breathing is difficult, give
                                           oxygen. Get medical attention immediately. 
               Ingestion:           If swallowed, do not induce vomiting. Give several glasses of water or milk. If vomiting
                                           occurs spontaneously, keep airway clear. Get medical attention immediately.

 

SECTION VII - SPECIAL PRECAUTIONS
HANDLING AND STORAGE PRECAUTIONS:
              Keep container tightly closed. Store in a cool, dry area protected from corrosion, Store away from other
              chemicals such as oxidizing agents, bases or metals.

STEPS TO BE TAKEN IF MATERIAL SPILLS OR LEAKS:

              Evacuate area. Wear proper safety gear. For small spills, neutralize with soda ash and, if permitted, flush to
              sewer with large amounts of water. For larger spills, dike the liquid and recover as much as possible into 
              polyethylene drums. Neutralize residue with soda ash and flush to sewer with large amounts of water, if
              permitted. Comply with applicable government regulations.

WASTE DISPOSAL METHOD:

              Hydrochloric acid is an EPA hazardous waste due to corrosivity and must be disposed of by an EPA approved
              hazardous waste facility. Comply with all local, state and federal regulations.

 

SECTION VII - SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION:

              Self-contained organic respirator should be available.

VENTILATION:

              Use ventilation to maintain TLV below 5 ppm.

EYE PROTECTION:

             Full face shield, chemical goggles.

SKIN PROTECTION:

             Acid suit, rubber boots, impervious gloves.

OTHER PROTECTIVE EQUIPMENT:

            As needed to avoid all bodily contact and breathing of vapor.
