Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath. High concentrations can cause pulmonary edema.
Ingestion:
Irritating to the gastro-intestinal tract, mildly toxic in large amounts.
Abdominal pain, vomiting, diarrhea may occur.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain. May
cause dermatitis, burns, and moderate skin necrosis. Persulfate allergy is
not uncommon and manifest itself in the form of a skin rash.
Eye Contact:
Causes irritation, redness, and pain. May cause burns.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Allergic persons may develop skin rash.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
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. Remove
contaminated clothing and shoes. Get medical attention. Wash clothing
before reuse. Thoroughly clean shoes 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. Contact
with oxidizable substances may cause extremely violent combustion.
Decomposes with liberation of oxygen which may intensify surrounding fire
conditions.
Explosion:
Strong oxidants may explode when shocked, or if exposed to heat, flame, or
friction. Also may act as initiation source for dust or vapor explosions.
Fire Extinguishing Media:
Use water spray to blanket fire, cool fire exposed containers, and to flush
non-ignited spills or vapors away from fire. Do not allow water runoff to
enter sewers or waterways.
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. Thermal decomposition is
strongly exothermic.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8.
Spills: Clean up spills in a manner that does not disperse dust into the
air. Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage and moisture. Isolate from any source of
heat or ignition. Avoid storage on wood floors. Separate from
incompatibles, combustibles, organic or other readily oxidizable materials.
Containers of this material may be hazardous when empty since they retain
product residues (dust, solids); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
ACGIH (TLV) TWA: 0.1 mg/m3
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because
it can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH
document, Industrial Ventilation, A Manual of Recommended Practices,
most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a full facepiece respirator with
dust/mist filter may be worn up to 50 times the exposure limit or the
maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. 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.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or
splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.

Unstable. Gradually decomposes losing oxygen. Decomposes more rapidly at
higher temperatures. Metals other than stainless steel are apt to cause
decomposition of persulfate solutions.
Hazardous Decomposition Products:
Oxides of sulfur and the contained metal. Oxygen is released.
Hazardous Polymerization:
Will not occur.

13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be handled as
hazardous waste and sent to a RCRA approved waste facility. Processing, use
or contamination of this product may change the waste management options.
State and local disposal regulations may differ from federal disposal
regulations.
Dispose of container and unused contents in accordance with federal, state
and local requirements.
