IV.   FIRE EXPLOSION & REACTIVITY DATA



      Flash Point:           N/A

      Flammable Limits:      N/A



      Firefighting Media:    Use dry chemical, carbon dioxide or regular foam. For larger fires use

                             regular foam (2000 Emergency Response Guidebook, DOT P 5800.5)





      Firefighting

      Procedure:             Move container away from fire area without risk. From a safe distance

                             and keeping upwind, apply flooding amounts of water to sides of

                             container exposed to fire for cooling purposes until well after the fire is

                             extinguished. Stay away from ends of tanks (2000 Emergency

                             Response Guidebook, DOT P 5800.5 Guide #153)

      Special Firefighting

      Procedure:             Use self-contained breathing apparatus. Extinguish using suitable

                             agents for type of fire.



      Unusual Fire Hazards: Hydrogen gas may form explosive mixtures in the air. At high

                            temperature toxic corrosive fumes of anhydrous gas may be emitted.



      Reactivity:            Stable

      Incompatibilities:     Contact with common earth metals, i.e. aluminum or magnesium,

                             produces hydrogen which may form explosive mixtures in the air.

      Decomposition or

      Byproducts:            In fire conditions products may include toxic and hazardous gases

                             including fumes of hydrogen chloride, oxides of copper, and chromium

                             oxides.

      Hazardous

      Polymerization:        Not reported to occur under normal temperatures and pressures.

       Skin Contact:        Remove contaminated clothing, rinse area of contact for at least 20

                            minutes with soap or mild detergent with large doses of water until no

                            evidence of chemical remains. In case of chemical burns, cover area

                            with proper dressing and bandage securely, but not tightly. Get

                            immediate medical attention.



       Eye Contact:         Rinse eyes immediately with large doses of water for at least 20 minutes,

                            occasionally lifting upper and lower eyelids, until no evidence of evidence

                            remains. Continue irrigation with normal saline until the pH has returned

                            to normal. Cover with sterile bandages and get immediate medical

                            attention.



       Ingestion:           Drink large amount of water or milk to dilute acid only if advised by

                            medical personnel. Ingested acid must be diluted 100 fold to render it

                            harmless to tissues. If vomiting persists, take fluid repeatedly. Seek

                            medical attention immediately.





VI.    SPILL PROCEDURES & WASTE DISPOSAL



       Spill:               Spills may be absorbed using cement powder or fly ash. Neutralize spills

                            with lime, sodium bicarbonate or crushed limestone, or with a water /

                            ammonia solution.



       Waste

       Disposal:            Follow all Federal, State and Local regulations when storing and

                            disposing of substances. Do not allow material to run off work area, and

                            final rinsing should be absorbed or vacuumed and disposed of in

                            accordance with regulations.



                            QC Patina Stain, and rinse water from the neutralization and cleaning of

                            newly stained surfaces, may contain amounts of sodium dichromate that

                            exceed federal hazardous waste limits. Proper disposal of QC Patina

                            Stain, and rinse water from the neutralization and cleaning of newly

                            stained surfaces is required. Consult local and federal guidelines for

                            proper disposal of these materials.



       Precautions for

       Safe Handling

       And Storage:         N/A



       Other Precautions:   Air Spill - knock down vapors with water spray, contain water as it may

                            become corrosive and dispose of properly.





VII.   PROTECTIVE CONTROL MEASURES



       Respirator:          Use proper NIOSH-OSHA respirator equipped with an acid cartridge with

                            HEPA filter for contamination levels found in work area.



       Ventilation:         Provide local exhaust to meet published exposure limits.



       Special:             N/A



       Protective Gloves:   Must wear appropriate protective gloves.



       Eye Protection:      Must wear splash-proof safety goggles or face shield to prevent

                            exposure.



       Other Protective

       Clothing Required:   Must wear appropriate protective (impervious) clothing equipment to

                            prevent possible skin contact.
