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

Potential Health Effects
----------------------------------

Inhalation:
Corrosive. Inhalation of vapors or mists will cause irritation with coughing, choking, and inflammation of the nose, throat, and upper respiratory tract.
Ingestion:
Corrosive. May cause burns of mouth, throat, and stomach, nausea, vomiting and diarrhea.
Skin Contact:
Corrosive. Can cause severe burns with discoloration and pain.
Eye Contact:
Corrosive. Permanent visual damage may occur. Highly corrosive to tissue.
Chronic Exposure:
Repeated exposure to dilute solutions may cause skin rash and possible sensitization.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired respiratory function may be more susceptible to the effects of the substance.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Call a physician, immediately. Wash clothing before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

5. Fire Fighting Measures

Fire:
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Can react with metals to release flammable hydrogen gas. Reactions may cause fire and explosion. In the event of a fire, assume that organic materials are involved and that an explosion may occur.
Explosion:
May form sensitive powerful explosive mixtures with organic materials.
Fire Extinguishing Media:
Water spray can be used to extinguish fires and cool fire-exposed containers.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Remove spilled perchloric acid by immediate and thorough washing with large amounts of water. Reduce with a weak reducung agent, (hypobisulfite or ferrous salt, plus sulfuric acid as an accelerator have been recommended), then neutralize with sodium carbonate or calcium oxide.


J. T. Baker NEUTRASORB® acid neutralizer is recommended for spills of this product.

7. Handling and Storage

Reagent bottle - maximum 1 pound, glass-stoppered, glass bottle; kept in a heavy glass tray with larger capacity. Additional laboratory storage should be in original bottles inside a glass container padded with glass wool and having greater capacity than the container. Carboys and large bottles should be stored on acid-resisting noncombustible shelves, in a noncombustible structure. All storage must be separated from combustible materials, organic materials, strong dehydrating agents; oxidizing and reducing agents. Perchloric acid must be stored where it will not freeze (freezing point about -4F). Protect against physical damage. Electrical wiring, etc., in storage areas must be of watertight type to protect against corrosive action of vapors. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
None established.
Ventilation System:
Do Not Use Perchloric Acid In A Hood Designed For Other Purposes. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practice, most recent edition, for details on proper ventilation design.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to the substance is apparent and engineering controls are not feasble, consult an industrial hygienist. For emergencies, or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres. If the exposure limit is exceeded and engineering controls are not feasible, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. Breathing air quality must meet the requirements of the OSHA respiratory protection standard (29CFR1910.134).
Skin Protection:
Rubber or neoprene gloves and additional protection including impervious boots, apron, or coveralls, as needed in areas of unusual exposure.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
