Kloz眉r鈩?
PRODUCT NAME:
Sodium Persulfate, Sodium Peroxydisulfate; Disodium
SYNONYMS:
Peroxydisulfate
In situ and ex situ chemical oxidation of contaminants and
GENERAL USE:
compounds of concern for environmental remediation applications.
MANUFACTURER EMERGENCY TELEPHONE NUMBERS
FMC CORPORATION (800) 424-9300 (CHEMTREC - U.S.)
Active Oxidants Division (303) 595-9048 (Medical - Call Collect)

2. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
鈥? White, odorless, crystals
鈥? Oxidizer.
鈥? Decomposes in storage under conditions of moisture (water/water vapor) and/or excessive heat causing
release of oxides of sulfur and oxygen that supports combustion. Decomposition could form a high
temperature melt. See Section 10 ("Stability and Reactivity").
POTENTIAL HEALTH EFFECTS: Airborne persulfate dust may be irritating to eyes,
nose, lungs, throat and skin upon contact. Exposure to high levels of persulfate dust may cause difficulty in
breathing in sensitive persons.

3. COMPOSITION / INFORMATION ON INGREDIENTS
Chemical Name CAS# Wt.% EC No. EC Class
Sodium Persulfate 7775-27-1 >99 231-892-1 Not classified as hazardous
4. FIRST AID MEASURES
EYES: Flush with plenty of water. Get medical attention if irritation occurs and persists.
SKIN: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists.
INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce
vomiting. Never give anything by mouth to an unconscious person. See a medical doctor immediately.
INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists,
contact a medical doctor.
NOTES TO MEDICAL DOCTOR: This product has low oral toxicity and is not irritating to
the eyes and skin. Flooding of exposed areas with water is suggested, but gastric lavage or emesis
induction for ingestions must consider possible aggravation of esophageal injury and the expected absence
of system effects. Treatment is controlled removal of exposure followed by symptomatic and supportive
care.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Deluge with water.
FIRE / EXPLOSION HAZARDS: Product is non-combustible. On decomposition releases
oxygen which may intensify fire. Presence of water accelerates decomposition.
FIRE FIGHTING PROCEDURES: Do not use carbon dioxide or other gas filled fire
extinguishers; they will have no effect on decomposing persulfates. Wear full protective clothing and self-
contained breathing apparatus.
FLAMMABLE LIMITS: Non-combustible
SENSITIVITY TO IMPACT: No data available

SENSITIVITY TO STATIC DISCHARGE: Not available
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: Spilled material should be collected and put in approved DOT container and
isolated for disposal. Isolated material should be monitored for signs of decomposition (fuming/smoking).
If spilled material is wet, dissolve with large quantity of water and dispose as a hazardous waste. All
disposals should be carried out according to regulatory agencies procedures.
7. HANDLING AND STORAGE
HANDLING: Use adequate ventilation when transferring product from bags or drums. Wear
respiratory protection if ventilation is inadequate or not available. Use eye and skin protection. Use clean
plastic or stainless steel scoops only.
STORAGE: Store (unopened) in a cool, clean, dry place away from point sources of heat, e.g.
radiant heaters or steam pipes. Use first in, first out storage system. Avoid contamination of opened
product. In case of fire or decomposition (fuming/smoking) deluge with plenty of water to control
decomposition. For storage, refer to NFPA Bulletin 430 on storage of liquid and solid oxidizing materials.
COMMENTS: VENTILATION: Provide mechanical general and/or local exhaust ventilation to
prevent release of dust into work environment. Spills should be collected into suitable containers to prevent
dispersion into the air.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
EXPOSURE LIMITS
Chemical Name ACGIH OSHA Supplier
0.1 mg/m3 (TWA)
Sodium Persulfate
ENGINEERING CONTROLS: Provide mechanical local general room ventilation to
prevent release of dust into the work environment. Remove contaminated clothing immediately and wash
before reuse.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Use cup type chemical goggles. Full face shield may be used.
RESPIRATORY: Use approved dust respirator when airborne dust is expected.

with incompatible materials can result in a material
decomposition or other uncontrolled reactions.
Oxygen that supports combustion and oxides of
HAZARDOUS DECOMPOSITION PRODUCTS:
sulfur.
COMMENTS: PRECAUTIONARY STATEMENT: Pumping and transport of Kloz眉r persulfate
requires appropriate precautions and design considerations for pressure and thermal relief.
Decomposing persulfates will evolve large volumes of gas and/or vapor, can accelerate exponentially with
heat generation, and create significant and hazardous pressures if contained and not properly controlled or
mitigated.
Use with alcohols in the presence of water has been demonstrated to generate conditions that require
rigorous adherence to process safety methods and standards to prevent escalation to an uncontrolled
reaction.

DERMAL LD50: > 10 g/kg [FMC Study Number: ICG/T-79.029]
ORAL LD50: 895 mg/kg (rat) [FMC Study Number: ICG/T-79.029]
INHALATION LC50: 5.1 mg/l (rat) [FMC I95-2017]
SENSITIZATION: May be sensitizing to allergic persons. [FMC Study Number: ICG/T-79.029]
TARGET ORGANS: Eyes, skin, respiratory passages
ACUTE EFFECTS FROM OVEREXPOSURE: Dust may be harmful and irritating.
May be harmful if swallowed.
CHRONIC EFFECTS FROM OVEREXPOSURE: Sensitive persons may develop
dermatitis and asthma [Respiration 38:144, 1979]. Groups of male and female rats were fed 0, 300 or 3000
ppm sodium persulfate in the diet for 13 weeks, followed by 5000 ppm for 5 weeks. Microscopic
examination of tissues revealed some injury to the gastrointestinal tract at the high dose (3000 ppm) only.
This effect is not unexpected for an oxidizer at high concentrations. [Ref. FMC I90-1151, Toxicologist
1:149, 1981].
