Hazard Symbols: | (25% solution) Moderate fire risk; strong irritant to skin and eyes. The pure material is a strong oxidizer and severe explosion hazard; should not be stored after preparation, nor heated above 30C. |
Safety: |
Severe skin and eye irritant. Questionable carcinogen with experimental tumorigenic data. Dangerous fire hazard by spontaneous chemical reaction. A powerful oxidizing agent; can cause ignition of organic materials on contact. Severe explosion hazard when shocked or exposed to heat. It may explode spontaneously in storage and should be used as soon as prepared. It will react with water or steam to produce heat; can react vigorously with reducing materials; emits toxic fumes on contact with acid or acid fumes. To fight fire, use CO2, dry chemical. Storage and Handling: Must be kept below 27° and not warmed over 30°. Do not add to hot materials. Do not add accelerator to this material. Store in original container with vented cap. Avoid bodily contact. This material is nearly always stored and handled as a 25% solution in an inert solvent. See also ACETYL PEROXIDE 25% solution (in dimethyl phthalate); and PEROXIDES, ORGANIC. |

DOT Classification: Forbidden
Stability: Acetyl peroxide (CAS NO.110-22-5) may explode if heated, or in contact with combustible materials. The pure material of Acetyl peroxide (CAS NO.110-22-5) should not be handled by untrained persons. It's unstable as the pure material and incompatible with organic materials.
Reactivity Profile: Peroxides, such as Acetyl peroxide (CAS NO.110-22-5), are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness.
Health Hazard: Contact with liquid causes irritation of eyes and skin.
Fire Hazard: Acetyl peroxide (CAS NO.110-22-5) may explode if contacted with fire and burn with accelerating intensity.
