Hazards and Protection.
Storage
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.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Stability
No data.
Incompatibilities
Reacts readily with reducing agents, including most organic compounds, to generate heat and products that may be gaseous (causing pressurization of closed containers).

Fire.
Fire fighting
Use dry chemical, graphite, or dry earth. Use water only if flooding quantities are available. Apply water from as far a distance as possible.
Fire potential
May ignite combustibles (wood, paper, oil, clothing, etc.).
Hazards
Increases intensity of fire and can start fires when in contact with organic combustibles
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
   Ingestion
Serious gi complications have resulted from the ingestion of concentrated solutions and enemas with dilute peroxide solutions.
   Inhalation
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.
   Skin
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.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Give large amount of water; do NOT induce vomiting; get medical attention.
   Inhalation
Remove from exposure; support respiration.
   Skin
Flush with water; treat caustic burns.
   Eyes
Irrigate with large quantities of water for at least 15 min.; get medical attention for caustic burns.
