[Fire Fighting] SMALL FIRES: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. LARGE FIRES: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams. Move containers from fire area if you can do it without risk. Do not move cargo or vehicle if cargo has been exposed to heat. Fight fire from maximum distance or use unmanned hose holders 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 hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. | |
[Fire Potential] Moderately flammable. Combustion with moderate heating. | |
[Ingestion] Administer an emetic to induce vomiting and call a physician | |
[Inhalation] Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols. | |
[Skin] Wash with plenty of soap and water. | |
[Eyes] Wash with plenty of water for 15 min. and get medical attention. | |
[Storage] Store in a cool, well-ventilated storage of noncombustible construction, distant from residences separate from other stocks, especially vulcanizing agents, easily oxidizable organic materials, and combustible material; avoid fire and sparks. Provide large-quantity storage room with cool sprinkler system. Protect containers against physical damage. Do not open containers in storage room. Do not place in glass-stopper or screw-capped containers because of possible explosion caused by frictional handling. Keep as cool as possible, but below 27C. Do not add hot material. Because of their instability, many peroxides are stored and handled in inert vehicle such as dimethyl phthalate. | |
[Handling] All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. | |
[Inhalation] Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur. | |
[Skin] Severe skin irritation and/or burns may occur. | |
[Eyes] Ingestion may result in burns to the lips, tongue, oral mucosa, and upper airway. Alkaline eye exposures produce distortion of cellular membranes, loss of corneal, the mucous membrane that lines the inner surface of the eyelid and the exposed surface of the eyeballl and lens epithelium and loss of endothelium of the cornea and blood vessels. | |
[Ingestion] Burns of the esophagus and less commonly the stomach may occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns. | |
[Hazards] May explode from heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Containers may explode when heated. Runoff may create fire or explosion hazard. | |

[Personal Protection] Protective gloves, goggles. Wear long firm body-shield, and fully protective clothing. Preferably handle this material in a draft. Persons handling peroxides should use safety glasses with side shields, goggles or face shield for eye protection. Emergency eyewash facilities should be provided. Gloves, aprons and other protective clothing as necessary should be used to prevent skin contact. Clothing and equipment that generate static electricity should be avoided. Smoking should be prohibited. | |
[Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
[Exposure Effects] Abnormally low blood pressure and apnea have been reported with severe poisonings. Cerebral edema, cerebral gas embolism, cerebral infarction, and seizures have been reported following ingestion of concentrated (35%) solutions. Death has been reported as a result of embolic cerebrovascular injury. | |

[Small spills/leaks] ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Stop leak if you can do it without risk. SMALL SPILLS: Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal. | |
[Stability] Reactive under confinement, extreme caution. | |
[Incompatibilities] Strongly reduced material such as sulfides, nitrides, and hydrides | |
[Decomposition] Becomes shock sensitive on heating and self-accelerating decomposition sets in at 49 C. | |
[Combustion Products] Fire may produce irritating, corrosive and/or toxic gases. | |
