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
Mixtures with combustible material can sometimes be ignited by friction or contact with moisture Mixtures with aluminum or zinc powder burn brilliantly.

Fire.
Fire fighting
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire.
Hazards
May explode from friction, heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard.
Combustion products
Fire may produce irritating and/or toxic gases.

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
Seek medical assistance.
   Inhalation
Aspirated zinc stearate may cause severe respiratory irritation.
   Skin
