General Description
A white crystalline solid. A strong oxidizing agent. Does not burn readily, but may cause spontaneous ignition of organic materials. Used as a bleaching agent and as a food preservative.

Hazards

Reactivity Alerts
Air & Water Reactions
Soluble in water.
Fire Hazard
Special Hazards of Combustion Products: Toxic oxides of nitrogen and sulfuric acid fumes may form in fire.

Behavior in Fire: Decomposes with loss of oxygen that increases intensity of fire (USCG, 1999)
Health Hazard
Inhalation produces slight toxic effects. Contact with dust irritates eyes and causes skin rash. (USCG, 1999)
Reactivity Profile
AMMONIUM PERSULFATE is a potent oxidizing agent. A powdered mixture with aluminum and water can explode [NFPA 491M 1991]. A mixture with sodium peroxide will explode if subjected to friction (crushing in a mortar), heating, or if a stream of carbon dioxide is passed over it [Mellor 10:464 1946-47]. Acidic solutions dissolve iron violently, [Mellor, 1947, Vol. 10, 470].
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from 140 Polymerizable warning [Oxidizers]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. If ammonium nitrate is in a tank, rail car or tank truck and involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, initiate evacuation including emergency responders for 1600 meters (1 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 140 Polymerizable warning [Oxidizers]:

SMALL FIRE: Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.

LARGE FIRE: Flood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)
Non-Fire Response
Excerpt from 140 Polymerizable warning [Oxidizers]:

Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL LIQUID SPILL: Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. (ERG, 2020)
Protective Clothing
U.S. Bu. Mines approved toxic dust mask; chemical goggles; rubber gloves; neoprene-coated shoes (USCG, 1999)

First Aid
INHALATION: remove to fresh air.

EYES: wash with water for 20 min.; call a physician.

SKIN: wash with water. (USCG, 1999)
