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.
Mixtures with combustible material can sometimes be ignited by friction or contact with moisture Mixtures with aluminum or zinc powder burn brilliantly.
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire.
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.
Fire may produce irritating 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.
Seek medical assistance.
Aspirated zinc stearate may cause severe respiratory irritation.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Immediately flush skin or eyes with running water for at least 20 minutes.
