3. HAZARDS IDENTIFICATION

Inhalation: Corrosive to the upper airways when inhaled in concentrations exceeding recommended
exposure limits. Short-term overexposure may cause muscle spasms, dizziness and collapse. Prolonged
overexposure may cause perforation of nasal septum, hoarseness of the voice, liver injury and red patches
on the skin. Chronic arsenic exposure may cause nervous system damage.
Eye Contact: Corrosive to the eyes.
Skin Contact: Severe irritation to the skin.
Ingestion: Corrosive. Can cause internal hemorrhage and death if consumed as a liquid.
Toxic by ingestion; Moderately toxic by dermal contact.

4. FIRST AID MEASURES

Inhalation: Remove from exposure. If severe breathing difficulty should arise immediately seek medical
aid. If breathing has stopped, administer artificial respiration or oxygen.
Eye Contact: Exposed eyes should be flushed with large amounts of saline or water for at least 15 minutes,
(greater than 1 liter per eye, minimum) using low pressure, taking care that the eyes remain open during this
entire procedure. If wearing contact lenses, immediately flush eyes with water for a short period prior to
removing contacts, then resume flushing procedures as described above. Immediately seek medical aid.
Skin Contact: Flush exposed skin with large amounts of water. Then use soap and water to clean area.
Remove contaminated clothing. Seek medical aid if severe irritation develops.
Ingestion: Following ingestion, if the patient can swallow without difficulty, administer small quantities of
water and/or demulcents (such as milk) to dilute the chromic acid. Do not administer anything by mouth if
difficulty with swallowing exists. DO NOT induce vomiting. Seek medical aid immediately. Do not attempt to
give anything to an unconscious person. Call a physician or poison center immediately.

5. FIRE FIGHTING MEASURES

Flash Point NA Lower Explosive Limit NA
Auto-ignition NA Upper Explosive Limit NA

Extinguishing Agents: Not applicable

Fire-Fighting Procedures: Fire from a separate fuel source may be intense enough to cause thermal
decomposition releasing toxic fumes and/or gases. Wear complete fire service protective equipment,
including full-face NIOSH/NFPA ?? approved self-contained breathing apparatus.
Fire and Explosion Hazard: This product will not burn. Closed containers may explode (due to the build up
of steam pressure) when exposed to extreme heat. Water could evaporate to expose a combustible residue.
Under fire conditions the product may emit irritants, toxic gas and/or fumes. May cause fire on contact with
combustible materials (e.g. oil-stained rags or sawdust).

6. ACCIDENTAL RELEASE MEASURES

Spill or Leak Procedures: (Product): Stop leak if no risk involved. Contain spill by using an inert non-
biodegradable absorbent material (e.g., kitty litter or synthetic absorbents). Shovel into an appropriate
container and dispose of waste in accordance with federal, state and local regulations. If material can be
recovered, use a vacuum system designed for liquid recovery. If a reportable quantity (RQ) is released into
the environment, report to the National Response Center (1-800-424-8802), the State Emergency Planning
Commission (SERC), the Local Emergency Planning Committee (LEPC) and/or your local fire department
depending on availability.
Reportable Quantities: If <1/2 gallon (7.5 lbs.) as CCA 60% or <2/3 gallon (9 lbs.) as CCA 50% is released
into the environment, the arsenic RQ of one (1) pound will be exceeded.
Waste Disposal: Dispose of waste in accordance with Federal and State Hazardous Waste regulations.
Place in tightly sealed, labeled containers. This product is an EPA characteristic waste as D004 and D007 in
40 CFR 261.

7. HANDLING AND STORAGE

Storage Conditions: Well ventilated area. Maintain good housekeeping. Keep properly labeled containers
closed when not in use. Protect from physical damage.
Caution: Do not wear contaminated clothing. Wash hands thoroughly before eating, drinking, using tobacco
products, and/or using restrooms.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Respiratory Protection: Wear a NIOSH approved respirator if airborne concentrations exceed the exposure
limits. Use a full-face air-purifying respirator equipped with acid-gas cartridges and a P100 pre-filter. Air
purifying respirators should not be used in oxygen deficient or IDLH atmospheres or if exposure
concentrations exceed ten (10) times the published limit.
Eye Protection: Splash-proof chemical goggles and face shield should be worn wherever splash hazards
exist.
Skin/Foot Protection: PVC, polyethylene or neoprene gloves are recommended. Wear long sleeves, pants
and leather or rubber shoes. Coveralls or aprons if needed.
Ventilation: Use local exhaust ventilation to maintain levels to below the exposure limits.
Other Protective Equipment: Facilities storing or utilizing this material must be equipped with an
emergency eyewash and safety shower station within easy access for quick drenching or flushing.

Cancers in humans have followed from long term consumption of Fowler's Solution, a medicinal trivalent
arsenical; inhalation and skin contact with inorganic trivalent arsenical sheep-dust; the combined inhalation
of arsenic trioxide (trivalent arsenical), sulfur dioxide, and other particulates from ore smelting in arsenic
trioxide production; and occupational exposure to nonwater-soluble hexavalent chromium.
