DOT-KennzeichnungOxidizer
BrandgefahrenExcerpt from ERG Guide 140 [Oxidizers]:CAUTION: Ammonium nitrate products may explode if involved in fire or contaminated with hydrocarbons (fuels), organic matter, other contaminants or when hot molten and contained. Treat as an explosive (GUIDE 112).Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances or reducing agents.

Anwendungen & Verwendung

Verwenden

Bleaching and oxidizing agent; promoter for emulsion polymerization reactions.

Excerpt from ERG Guide 140 [Oxidizers]:· Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death.
GefahrenübersichtDanger of sensitization of airways and skin[MAK] Frequent skin rashes are reported in workers exposed to persulfates (S2O8). Rats inhaling 4-20 mg/m3 of ammonium persulfate 23.5 hours/day for 7 days show signs of lung inflammation and loss of body weight. The TLV is proposed to reduce irritation of skin, throat, and respiratory tract. [ACGIH] A skin, eye, and respiratory tract irritantMay cause skin sensitization, dermatitis, and asthma after prolonged contact[ICSC] An irritantMay cause skin and respiratory sensitization after prolonged contact[MSDSonline] See Ammonium persulfate and Potassium persulfate.

EPA Safer ChemicalChemical: Sodium peroxydisulfate
Reactivity AlertsStrong Oxidizing Agent
Reactivity ProfileSODIUM PERSULFATE is a strong oxidizing agent. Reacts with many combustible materials and reducing agents, often vigorously enough to start fires or cause explosions [Handling Chemicals Safely 1980 p. 855]. Decomposes gradually under ordinary conditions decomposition is promoted by moisture and heat [Merck]. Decomposed by alcohol and silver ions [Merck].
BrandbekämpfungExcerpt from ERG Guide 140 [Oxidizers]:In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water.
Erste-Hilfe-MaßnahmenFresh air, rest. Artificial respiration may be needed. Refer for medical attention.First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Give one or two glasses of water to drink. Refer for medical attention .
Freisetungsmaßnahmen· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· Keep combustibles (wood, paper, oil, etc.) away from spilled material.
Erste HilfeExcerpt from ERG Guide 140 [Oxidizers]:General First Aid:
Sichere LagerungWell closed. Separated from combustible substances, reducing agents, strong bases and powdered metals.
Expositionsschutz und Persönliche Schutzausrüstung· Wear positive pressure self-contained breathing apparatus (SCBA).
Freisetung ohne BrandExcerpt from ERG Guide 140 [Oxidizers]:
Verschüttetes entsorgenPersonal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then wash away with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.
Isolation and EvacuationExcerpt from ERG Guide 140 [Oxidizers]:Immediate precautionary measure
Eye PreventionWear safety goggles or eye protection in combination with breathing protection if powder.
Fire PreventionNO contact with combustible substances.
Inhalation RiskEvaporation at 20 °C is negligiblea harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Unerwünschte WirkungenSkin Sensitizer - An agent that can induce an allergic reaction in the skin.
ExpositionspfadeThe substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
ToxizitätsübersichtThe CIR Expert Panel concluded that Ammonium, Potassium, and Sodium Persulfate are safe as used as oxidizing agents in hair colorants and hair lighteners designed for brief discontinuous use followed by thorough rinsing from the hair and skin. The Panel also concluded that the available data are insufficient for determining the safety of these persulfates in leave-on products and dentifrices.Safe for use in cosmetics, with qualifications
Signs and SymptomsCough. Laboured breathing. Sore throat. Wheezing.Redness. Pain.Diarrhoea. Nausea. Sore throat. Vomiting.
