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, nitrogen and oxygen that supports combustion. Decomposition could form a
high temperature melt. See Section 10 ("Stability and Reactivity").
鈥? Moderate oral toxicity.

Ammonium Persulfate (7727-54-0) Date: 04/30/2006
POTENTIAL HEALTH EFFECTS: Airborne dust may be irritating to eyes, nose, lungs,
throat and skin upon contact. Exposure to high levels of dust may cause difficulty in breathing in sensitive
persons.

Chemical Name CAS# Wt.% EC No. EC Class
Ammonium Persulfate 7727-54-0 >99 231-786-5 O, R8; Xn, 22; Xi 36/37/38,
42/43
4. FIRST AID MEASURES
EYES: Flush with water for at least 15 minutes. If irritation occurs and persists, obtain medical
attention.
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 moderate oral toxicity and is
minimally irritating to the eyes. Flooding of exposed areas with water is suggested, but gastric lavage or
emesis induction for ingestions must consider the possible aggravation of esophageal injury and the
expected absence of systemic 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.

Ammonium Persulfate (7727-54-0) Date: 04/30/2006
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: Not 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 when contact
is expected. 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.

Ammonium Persulfate (7727-54-0) Date: 04/30/2006
ENGINEERING CONTROLS: Provide mechanical local and/or general room ventilation to
prevent release of dust into the work area. Remove contaminated clothing immediately and wash before
reuse.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Use cup type chemical type goggles. Full face shield may be used.
RESPIRATORY: Use approved dust respirator when airborne dust is expected.
PROTECTIVE CLOTHING: Rubber or neoprene footwear. Normal work clothes.
GLOVES: Wear chemical protective gloves made of materials such as rubber or neoprene.
Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for
leaks.

10. STABILITY AND REACTIVITY
Heat, moisture and contamination.
CONDITIONS TO AVOID:
Stable (becomes unstable in presence of heat,
STABILITY:
moisture and/or contamination).
Will not occur
POLYMERIZATION:
Acids, alkalis, halides (fluorides, chlorides,
INCOMPATIBLE MATERIALS:
bromides and iodides), combustible materials, most
metals and heavy metals, oxidizable materials,
other oxidizers, reducing agents, cleaners, and
organic or carbon containing compounds. Contact
with incompatible materials can result in a material
decomposition or other uncontrolled reactions.
Oxygen that supports combustion and oxides of
HAZARDOUS DECOMPOSITION PRODUCTS:
sulfur and nitrogen.
COMMENTS: PRECAUTIONARY STATEMENT: Use of persulfates in chemical reactions
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.
