Special Fire Fighting Procedure: Evacuate area and fight fire from a
                                 safe distance or a protected loca-
                                 tion. Approach fire from upwind.
                                 Containers may explode in the heat
                                 of the fire. Use water in flooding
                                 quantities as a spray or fog to keep
                                 fire-exposed containers cool. Apply
                                 water, as an extinguishant or as a
                                 coolant from as far a distance as
                                 possible. Move containers away from
                                 fire area if it can be done without
                                 risk.avoid spraying water directly
                                 into the acid container. Do not
                                 direct water spray at source of leak.
                                 Use water spray or fog to reduce or
                                 direct vapors. Do not enter without
                                 wearing specialized protective
                                 equipment suitable for the situation.

                                 niosh approved or equivalent) may be
                                 necessary. Trained personnel may
                                 neutralize spill.   

Fire And Explosion Hazards: Contact with most metals especially when
                            sulfuric acid is diluted with water
                            produces highly flammable hydrogen gas
                            which may form explosive mixture in air.
                            Fire may result from the heat generated by
                            contact of concentrated sulfuric acid with
                            combustible materials.
                            Sulfuric acid reacts violently with water
                            and organic materials with evolution of
                            heat. During fire, irritating/toxic sulfur
                            oxides may be generated. Containers may
                            explode in the heat of a fire.

Carcinogenicity: Iarc Has Concluded There Is Sufficient Evidence That
                 Occupational Exposure To Strong Inorganic Acid Mists
                 Containing Sulfuric Acid Is Carcinogenic To Humans
                 (Group 1)(6). Many studies have reported an excess of
                 cancer of larynx, and to a lesser extent the lungs, 
                 in a wide variety of processes involving the use of 
                 strong inorganic acids including sulfuric acid.
                 Throughout these studies,sulfuric acid mists were the
                 most common exposure, and in two studies, the number
                 of cancers increased as exposure increased (6).
                  
NTP: No      IARC: No         Z  List: Yes            OSHA Reg: Yes

Teratogenicity And Embryotoxicity: NA (No Human Information Is
                                       Available). 
    
Mutagenicity: There was a significantly higher number of sister
              chromatoid exchanges, micronuclei and chromosomal
              aberations in cultured lymphocytes (white blood cells)
              from workers exposed to sulfur dioxide in a sulfuric
              acid factory (6).
  
Reproductive Toxicity/Synergistic Effects: NA 

Primary Routes Of Entry: Eye contact, skin contact, inhalation of
                         mist, and ingestion.

Acute Effects Of Exposure: 

Inhalation: Sulfuric acid is corrosive and can cause severe irritation
            or corrosive damage if inhaled. The degree and severity of
            respiratory effects are influenced by factors such as the
            physical state and particle size of the aerosol or mist,
            deposition site, concentration and humidity. Sulfuric acid
            can cause severe lung damage with a life-threatening 
            accumulation of fluid in the lungs (pulmonary edema). The
            symptoms of pulmonary edema such as coughing and short-
            ness of breath can be delayed for several hours or days 
            after the exposure. These symptoms are aggravated by 
            Physical exertion. Long term lung damage may result from a
            severe short term exposure (5).Asthma can be aggravated by
            exposure to sulfuric acid (5,12,13).

Skin Contact: Can cause severe burns and irritation (redness,swelling, 
              and pain) which may result in permanent scarring.
              Extensive acid burns can result in death. High mist or 
              aerosol concentration may cause redness, irritation and 
              burns to the skin if contact is prolonged.

Eye Contact: Can cause severe irritation, burns and permanent damage
             including blindness.

Ingestion: Sulfuric acid is corrosive and can cause burns to the
           mouth,throat,esophagus and stomach if ingested. 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 vomiting (aspiration) can cause serious lung 
           injury and death.

Skin Absorption: Non Identified

Chronic Effects Of Exposure:

Dental Erosion: Exposure to high concentrations ( reportedly up to 16
                mg / m3 ) cause dental erosion (10). etching of teeth
                may occur after a few weeks exposure, progressing to
                erosion after a few months exposure (5). Dental etch-
                ing and erosion occurred about 4 times as frequently
                in a high exposure group(over 0.3 mg/m3) compared to a
                low exposure group (below 0.07 mg/m3).(6)      

Skin Effects: Repeated exposure to low concentration of acid mists or
              aerosols can cause dermatitis (red, itchy, dry skin).

Inhalation Effects: Repeated exposure to sulfuric acid mists or
                    aerosol could cause symptoms of respiratory 
                    irritation such as bronchial hyperreactivity.

Target Organs: Respiratory system, eyes, skin, teeth, and kidneys.

Other Health Hazards: 

Medical Conditions Generally Aggravated By Exposure:
 Respiratory disease, and damaged skin.
                                                                                                                                                                     
Emergency And First Aid Procedures:

Ingestion: Never give anything by mouth if victim is rapidly losing
           consciousness, or is unconscious or convulsing. Have victim
           rinse mouth thoroughly with water. Do not induce vomiting.
           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 admin-
           istration 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 physicianís
            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
             irritation persists, repeat flushing. Quickly, transport
             victim to an emergency facility.
 
Skin Contact: Immediately flush skin with lukewarm water for at least
              20-30 minutes, by the clock. Under running water, remove
              contaminated clothing, 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. Com-
              pletely decontaminate clothing,shoes, and leatherwears
              before reuse or discard.

Conditions To Avoid: Heat and water

Hazardous Polymerization: Will not occur.

Decomposition Products: Hydrogen and oxides of sulfur

Incompatibles: Can react with most metals generating flammable
               hydrogen gas.React vigorously, violently or explosively
               with many organic and inorganic chemicals including
               water, acrylonirile, alkali solutions, carbides,
               chlorates, fulminates, nitrates, perchlorates, 
               permangenates, picrates, metal acetylides or carbides,
               epichlorohydrin, aniline, ethylenediamine, alcohols
               with strong hydrogen peroxide, chlorosulfonic acid,
               cyclopentadiene, hydrofluoric acid,nitromethane, 4-
               nitrotoluene, phosphorous (iii) oxide, potassium,
               sodium, ethylene glycol,isoprene, styrene (15,17,18).
               Acetaldehyde and allyl chloride may polymerize
               violently in the presence of sulfuric acid (17).
               Hazardous gases such as hydrogen cyanide, hydrogen
               sulfide, and acetylene, are evolved on contact with
               chemicals such as cyanides, sulfides and carbides (16).
               References 15, 17, and 18 provide more complete lists
               of chemicals that may produce hazardous chemical
               reactions with sulfuric acid.   

Corrosivity To Metals: Very corrosive to most metals.

Oxidizing Properties: Pure or concentrated sulfuric acid is a good
                      oxidizing agent(23), while hot concentrated
                      sulfuric acid is a strong oxidizing agent (24).
                      Although the degree of oxidizing ability of
                      sulfuric acid may vary from concentrated to
                      dilute, or, from room temperature to hot,
                      sulfuric acid is nevertheless an oxyacid with
                      oxidizing ability.

Effect On Plastics: Many plastics do not resist concentrated sulfuric
                    acid of greater than 50-60%. Teflon is the only
                    common plastic that resists at all concentrations
                    (14).

               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 cleanup.
             Ensure cleanup is conducted by fully-trained personnel
             only. wear adequate personal protective equipment. Remove
             or isolate flammable or incompatible materials. 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 chemical. 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. Fush 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.

                                                                                
Disposal Procedure: Dispose in accordance with all applicable federal,
                    state, and local environmental regulations.

                       Colorimetric detector tubes: Commercially
                       available.  

Engineering Controls: Engineering methods to control hazardous
                      conditions are preferred. Methods include
                      mechanical ventilation (dilution and local
                      exhaust), process or personnel enclosure,
                      control of process conditions, and process
                      modifications(e.g., substitution of a less
                      hazardous acid/substance).
                      Administrative controls and personal protective
                      equipment may also be required.Because of the
                      high potential hazard associated with this
                      substance, stringent control measures such as
                      Enclosure or isolation are recommended when deal-
                      ing with mists. Use corrosion-resistant local
                      exhaust ventilation systems separate from other
                      exhaust ventilation systems. Cleaning of
                      contaminated exhaust air before release to the
                      outdoors may be necessary. Supply sufficient
                      replacement air to make up for air removed by
                      exhaust system.                       

Personal Protective Equipment: If engineering controls and work
                               practices are not effective in
                               controlling exposure to this material,
                               then wear suitable personal protective
                               equipment including approved
                               respiratory protection. Have 
                               appropriate equipment available for use
                               in emergencies such as spills or fire.
                               If respiratory protection is required,
                               institute a complete respiratory
                               protection program including selection,
                               fit testing training, maintenance and
                               inspection. Refer to csa standard

             Section 9 - Storage And Handling Precautions
----------------------------------------------------------------------

Storage: Store in tightly closed corrosion-resistant container. Store
         in a dry, and well ventilated place. Do not store in vicinity
         of incompatible materials. Keep quantities stored as small as
         possible. Avoid bulk storage indoors.
 
Handling: This material is corrosive, oxidizer, and very toxic. Before
          handling,it is important that engineering controls are
          operating and that protective equipment requirements and
          personal hygiene measures are being followed. People working
          with this chemical should be properly trained regarding its
          hazards and its safe use.
          Avoid producing chemical mist or vapor. Prevent the release
          of mist or vapor into the air. Use the smallest possible
          amounts in an area separate from the storage area. When
          handling large quantities, closed handling systems should be
          used. Unprotected persons should avoid all contacts with
          this chemical including contaminated equipment.
          Label containers. Avoid damaging containers. Keep containers
          tightly closed when not in use. Assume that empty containers
          contain residues which are hazardous. Use corrosion-
          resistant transfer equipment when dispensing. Whenever
          possible, use self-closing, portable containers for dispens-
          ing small amounts of this material. Never transfer liquid
          by pressurizing the original container with air or inert
          gas. Follow the chemical supplier's advice regarding venting
          of drums. Immediately contact the supplier for handling
          Instruction if drums of this material appear to be swollen.
          Have suitable emergency equipment for fire,spills and leaks
          readily available. Practice good housekeeping. Maintain
          handling equipment. Comply with applicable regulations. Do
          not get in eyes, on skin, or on clothing. Wash thoroughly
          with water after handling. Remove contaminated clothing
          immediately.Keep contaminated clothing in closed container.
          Discard or launder before rewearing. Inform laundry person-
          nel of contaminantís hazards. Do not eat or drink in work
          area.

Note: Material is electrically conductive. Do not store or handle near
      electric currents. Read the entire msds and label before storage
