Inhalation: Corrosive! Inhalation of vapors can cause coughing,
     choking, inflammation of the nose, throat, and upper
       respiratory tract, and in severe cases … DEATH!

Ingestion: Corrosive! Swallowing HCL can cause immediate pain
    and burns of the mouth, throat, esophagus and
        gastrointestinal tract. May cause nausea, vomiting, and
           diarrhea (ewww!)

 Skin Contact: Can cause redness, pain, and severe skin burns.
     Concentrated solutions cause deep ulcers and discolor skin.

 Eye Contact: Vapors are irritating and may cause damage to
     the eyes. Contact may cause severe burns and permanent
        eye damage.




Chronic Exposure: Long – term exposure to concentrated
  vapors may cause erosion of teeth. Long – term exposures
     seldom occur due to the corrosive properties of the acid.

Stability: stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
            when heated to decomposition, it emits toxic hydrogen
             chloride fumes and will react with water or steam to
             produce heat and toxic and corrosive fumes.
Incompatibilities: A strong mineral acid, concentrated HCl is
    incompatible with many substances and highly reactive
    with strong bases, metals, metal oxides, hydroxides, amines,
    carbonates, and other alkaline materials. It is also
    incompatible with materials such as cyanides, sulfites,
    sulfides, and formaldehyde.
Conditions to avoid: heat and direct sunlight.

  Store in a cool, dry, ventilated storage area with acid resistant
    floors, and good drainage.
       Protect from physical damage.
   Do not wash out container and use it for other purposes.
            When diluting, the acid should always be added slowly to
              water, and only in small amounts.
   Never use hot water and never add water to the acid. Water
      added to acid can cause uncontrolled boiling and splashing.

Observe all warnings and precautions listed for the product!!!

 Environmental Fate:
      When released into the soil, this material is NOT expected
        to biodegrade. When released into the soil, this material
           may leach into groundwater.
Environmental Toxicity:
     This material is expected to be toxic to the aquatic life.

            Whatever cannot be
            saved for recovery or
            recycling should be
            handled as hazardous
            waste and sent to a
            R C R A approved
            waste facility.

Technology Description:
          Although HCl acid recovery technology exists for large scale
          manufacturers, no cost-effective method had been developed
            for galvanizers and small – to medium – steel plants until
                Beta developed its new system between 1989 and 1994.
            The new HCl recovery recycles used acid solution from the
              pickling process. Without recycling, waste HCl solution is
                  disposed of by injection into deep wells or the acid is
                neutralized and the waste is then transported to a disposal
            site. With the new recovery system, acid is pumped through a
               prefilter to an evaporator where it is heated until the water
                     and acid vaporize, leaving only concentrated iron
                               chloride that is recuperated.
 The water /acid vapor is condensed into HCl, reconcentrated, and pumped
                                to the pickling tanks.
  27 Aprilacid is recovered, the water reused, [] product is sold at a profit.

The acid recovery system delivers significant savings. Currently,
 a typical small – to medium – size steel manufacturing plant
   spends $14 / ton to clean its products. With Beta’s recovery
 system, manufacturers can slash that cost to just $3.40 / ton.
More over, acid recovery requires minimal labor, and the life
 expectancy of a recovery system exceeds that of a conventional
   acid neutralization system by at least 3 yrs.
The recovery system also saves energy by eliminating the acid –
 neutralization step and the need to transport and dispose of
   waste.
