Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Reacts readily with reducing agents, including most organic compounds, to generate heat and products that may be gaseous (causing pressurization of closed containers).
Use dry chemical, graphite, or dry earth. Use water only if flooding quantities are available. Apply water from as far a distance as possible.
May ignite combustibles (wood, paper, oil, clothing, etc.).
Increases intensity of fire and can start fires when in contact with organic combustibles
Fire will produce irritating, corrosive and/or toxic gases.
Serious gi complications have resulted from the ingestion of concentrated solutions and enemas with dilute peroxide solutions.
Inhalation of vapors from concentrated (greater than 10%) solutions may result in severe pulmonary irritation. Interstitial lung disease and respiratory arrest have also been reported following massive exposures.
Dermal exposure to dilute (3%) solutions generally results in a bleaching of the affected area in association with a tingling sensation and lasts 2 to 3 hours, if washed promptly after contact.
Give large amount of water; do NOT induce vomiting; get medical attention.
Remove from exposure; support respiration.
Flush with water; treat caustic burns.
Irrigate with large quantities of water for at least 15 min.; get medical attention for caustic burns.
