MUTAGENICITY: N/E SEE ALSO (5)

REPRODUCTIVE TOXICITY/SYNERGISTIC EFFECTS: NA 

PRIMARY ROUTES OF ENTRY: EYE CONTACT, SKIN CONTACT, INHALATION OF MIST, AND
                         INGESTION.

ACUTE EFFECTS OF EXPOSURE: 

INHALATION: HCl IS A VERY STRONG ACID. SOLUTIONS CAN BE EXTREMELY CORROSIVE.THE
            SEVERITY OF EFFECTS DEPENDS ON THE CONCENTRATION OF THE SOLUTIONS
            AND THE DURATION OF CONTACT. IN GENERAL,HCl SOLUTIONS AND MIST WITH
            A pH OF 3 OR LESS ARE A SIGNIFICANT HEALTH CONCERN. VAPOR OR MIST
            FROM CONCENTRATED SOLUTIONS CAN CAUSE SEVERE NASAL IRRITATION, SOAR
            THROAT, CHOKING, COUGHING AND DIFFICULTY BREATHING (50-100 PPM).(2)
            PROLONGED EXPOSURE CAN CAUSE BURNS AND ULCERS TO THE NOSE, AND
            THROAT. SEVER EXPOSURES (e.g.,1000 - 2000 PPM), FOR EVEN A FEW
            MINUTES, CAN CAUSE A LIFE-THREATENING ACCUMULATION OF FLUID IN THE
            LUNGS (PULMONARY EDEMA). (2) SYMPTOMS OF PULMONARY EDEMA SUCH AS
            SHORTNESS OF BREATH CAN BE DELAYED FOR SEVERAL HOURS AFTER THE
            EXPOSURE.

SKIN CONTACT: HYDROCHLORIC ACID LIQUID CAN CAUSE SEVERE IRRITATION (REDNESS,
              SWELLING, AND PAIN) AND CORROSIVE SKIN DAMAGE WITH PERMANENT SCAR-
              RING (OR EVEN DEATH). HIGH VAPOR OR MIST CONCENTRATION MAY CAUSE
              REDNESS, IRRITATION AND BURNS TO SKIN IF CONTACT IS PROLONGED.
              SKIN COVERED BY PERSPIRATION-DAMPENED CLOTHING CAN ALSO BE
              AFFECTED. (2)

EYE CONTACT: LOW CONCENTRATIONS OF VAPOR OR MIST (10-35 PPM) CAN BE IMMEDIATELY
             IRRITATING, CAUSING REDNESS.(2) CONCENTRATED VAPOR, MIST OR SPLASHED
             LIQUID CAN CAUSE SEVERE IRRITATION, BURNS AND PERMANENT BLINDNESS.(4)

INGESTION: HCl SOLUTIONS CAN CAUSE CORROSIVE BURNS TO MOUTH, THROAT, ESOPHAGUS AND
           STOMACH. SYMPTOMS MAY INCLUDE DIFFICULTY IN SWALLOWING, INTENSE THIRST,
           NAUSEA, VOMITING, DIARRHEA, AND IN SEVERE CASES, COLLAPSE AND DEATH.
           SMALL AMOUNTS OF ACID WHICH ENTERS THE LUNGS DURING INGESTION OR VOMIT-
           ING (ASPIRATION) CAN CAUSE SERIOUS LUNG INJURY AND DEATH.

SKIN ABSORPTION: NON IDENTIFIED

CHRONIC EFFECTS OF EXPOSURE

DENTAL EROSION: REPEATED EXPOSURE TO LOW CONCENTRATION OF HCl MIST CAN CAUSE
                BROWNISH DISCOLORATION AND DAMAGE TO TOOTH ENAMEL. DENTAL
                EROSION BECOMES MORE SEVERE WITH INCREASED EXPOSURE. (2,3)

SKIN EFFECTS: REPEATED EXPOSURE TO LOW CONCENTRATION OF ACID SOLUTIONS, MIST
              OR VAPOR CAN CAUSE REDNESS, SWELLING, AND PAIN (DERMATITIS).

INHALATION EFFECTS: REPEATED EXPOSURE TO LOW CONCENTRATION OF ACID MIST OR
                    VAPOR MAY CAUSE BLEEDING OF NOSE AND GUMS. (9) CHRONIC
                    BRONCHITIS AND STOMACH PAIN (GASTRITIS)HAVE ALSO BEEN
                    REPORTED. (8)

TARGET ORGANS: RESPIRATORY SYSTEM, EYES, AND SKIN.

OTHER HEALTH HAZARDS 

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: DAMAGED SKIN                                                                                                                                                                     

EMERGENCY AND FIRST AID PROCEDURES:

INGESTION: NEVER GIVE ANYTHING BY MOUTH IF VICTIM IS RAPIDLY LOSING CONSCIOUS-
           NESS, OR IS UNCONSCIOUS OR CONVULSING.
           HAVE VICTIM RINSE MOUTH THOROUGHLY WITH WATER. DO NOT INDUCE VOMI-
           TING. HAVE VICTIM DRINK 240-300 mL (8 TO 10 OZ.) OF WATER. IF MILK
           IS AVAILABLE IT MAY BE ADMINISTERED AFTER THE WATER HAS BEEN GIVEN.
           IF VOMITING OCCURS NATURALLY, HAVE VICTIM LEAN FORWARD TO REDUCE
           RISK OF ASPIRATION. REPEAT ADMINISTRATION OF WATER. QUICKLY, TRANSPORT
           VICTIM TO AN EMERGENCY FACILITY.

INHALATION: TAKE PROPER PRECAUTIONS TO ENSURE YOUR OWN SAFETY BEFORE ATTEMPTING
            RESCUE; e.g., WEAR APPROPRIATE PROTECTIVE EQUIPMENT, USE THE BUDDY
            SYSTEM. REMOVE SOURCE OF CONTAMINATION OR MOVE VICTIM TO FRESH AIR.
            IF BREATHING IS DIFFICULT,OXYGEN MAY BE BENEFICIAL IF ADMINISTERED
            BY A PERSON TRAINED IN ITS USE, PREFERABLY ON A PHYSICIAN’S ADVICE.
            ENSURE VICTIM IS COMPLETELY AT REST, DO NOT ALLOW ANY PHYSICAL
            EXERTION. SYMPTOMS MAY BE DELAYED UP TO 48 HOURS AFTER EXPOSURE.
            IMMEDIATELY TRANSPORT VICTIM TO AN EMERGENCY MEDICAL FACILITY.

EYE CONTACT: IN CASE OF EYE CONTACT, IMMEDIATELY FLUSH THE AFFECTED EYE(S) WITH
             PLENTY OF LUKEWARM WATER, GENTLY FLOWING WATER FOR AT LEAST 20-30
             MINUTES, BY THE CLOCK, HOLDING THE EYELID(S) OPEN. NEUTRAL SALINE
             SOLUTION MAY BE USED AS SOON AS IT IS AVAILABLE. DO NOT INTERRUPT
             FLUSHING. IF NECESSARY, KEEP EMERGENCY VEHICLE WAITING. TAKE CARE
             NOT TO RINSE CONTAMINATED WATER INTO THE NON-AFFECTED EYE. IF IR-
             RITATION PERSISTS, REPEAT FLUSHING. QUICKLY, TRANSPORT VICTIM TO
             AN EMERGENCY FACILITY.

SKIN CONTACT: IMMEDIATELY FLUSH SKIN WITH LUKEWARM WATER FOR AT LEAST 20-30 MIN-
              UTES, BY THE CLOCK. UNDER RUNNING WATER, REMOVE CONTAMINATED CLOTH-
              ING, SHOES, AND LEATHERWEARS (e.g., WATCHBANDS, BELTS). DO NOT
              INTERRUPT FLUSHING. IF NECESSARY, KEEP EMERGENCY VEHICLE WAITING.
              TRANSPORT VICTIM TO AN  EMERGENCY CARE FACILITY IMMEDIATELY.
              COMPLETELY DECONTAMINATE CLOTHING, SHOES, AND LEATHERWEARS BEFORE
              RE-USE OR DISCARD.

                     SECTION 7- SPILL AND DISPOSAL PROCEDURE 

-------------------------------------------------------------------------------


STEPS TO BE TAKEN IN THE EVENT OF A SPILL OR DISCHARGE

PRECAUTIONS: RESTRICT ACCESS TO AREA UNTIL COMPLETION OF CLEAN-UP. ENSURE CLEAN-
             UP IS CONDUCTED BY FULLY-TRAINED PERSONNEL ONLY. WEAR ADEQUATE
             PERSONAL PROTECTIVE EQUIPMENT. VENTILATE AREA. NOTIFY GOVERNMENT
             OCCUPATIONAL HEALTH AND SAFETY AND ENVIRONMENTAL AUTHORITIES.
 
CLEAN-UP: DO NOT TOUCH SPILLED MATERIAL. KEEP UPWIND AND OUT OF LOW AREAS.
          AVOID INHALING VAPOR. STOP OR REDUCE LEAK IF IT CAN BE DONE WITHOUT
          RISK. PREVENT MATERIAL FROM ENTERING SEWERS, WATERWAYS, OR CONFINED
          SPACES. RECOVER SPILLED ACID IF FEASIBLE. CONTAIN SPILL WITH EARTH,
          SAND, OR ABSORBENT MATERIAL WHICH DOES NOT REACT WITH SPILLED CHEMIC-
          AL.FOR SMALL SPILLS, CONTAIN AND SOAK UP SPILL WITH ABSORBENT MATERIAL
          WHICH DOES NOT REACT WITH SPILLED CHEMICAL. PUT MATERIAL IN SUITABLE,
          COVERED, LABELED CONTAINER. FLUSH AREA WITH WATER. DO NOT GET WATER
          INSIDE CONTAINERS. CONTAMINATED ABSORBENT MATERIAL MAY POSE THE SAME
          HAZARDS AS THE SPILLED PRODUCT.
          FOR LARGE SPILLS, CONTACT FIRE AND EMERGENCY SERVICES AND SUPPLIER FOR
          ADVICE. WATER FOG OR SPRAY MAY BE NECESSARY TO KNOCK DOWN VAPORS.
