Hazards and Protection.
should be stored in cool, ventilated, isolated area away from org or other easily oxidizable materials and.Acute fire hazards. Containers should be kept closed and clearly labeled. Peroxides, org because of their instability, many peroxides are stored and handled in an inert vehicle such as dimethylphthalate. Storage temperature should not exceed 30C.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Organic compounds can ignite on contact with concentrated peroxides, strongly reduced material such as sulfides, nitrides, and hydrides
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.
Dangerous fire hazard by chem reaction with reducing agents or exposure to heat. They are powerful oxidizers. Peroxides, organic although flashpoints of most organic peroxides are not exceptionally Low fire hazard, when ignited they burn more furiously than corresponding flammable liquid not containing the peroxy linkage. Org peroxides contain sufficient available oxygen to support their own combustion in absence of atmospheric oxygen.
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.
Fire may produce irritating, corrosive and/or toxic gases.
Coma occurred 30 minutes after ingestion of mekp in one case.
Spontaneous vomiting and hematemesis, with moderate to severe gastroesophageal injury (gastritis, hemorrhagic esophagitis) occurred in most cases; one case of gastric perforation and one case of esophageal strictures were reported.
Respiratory complications following ingestion of mekp have included aspiration pneumonitis after spontaneous emesis, respiratory distress, and interstitial pneumonia/ards.
METHYL ETHYL KETONE PEROXIDE is moderately irritating at concentrations of 3% and severely irritating in concentrations of 40% after ocular instillation. CYCLOHEXANONE PEROXIDE produces severe eye injury.
Mucosal if no respiratory compromise is present, dilute immediately with milk or water; no more than 8 ounces in adults and 4 ounces in children. Gastric ipecac contraindicated. Consider insertion of a small, flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions; the risk of further mucosal injury must be weighed against potential benefits.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Flush with water for at least 15 min.; get medical attention.
