Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
May cause death or permanent injury after very short exposure to small quantities. Produces marked irritation of skin and mucous membranes. May cause liver injury. (EPA, 1998)
Maintain an open airway and assist ventilation if nescessary. treat coma, seizures, hypotension, and renal failure if they occur. There is no specific antidote. Administer activated charcoal (although boric acid is not well absorbed). Consider gastric lavage for large ingestions. Boric acid, Borates, and Boron
Smother fire with dry sand or dry clay or spray with water. DO NOT use carbon dioxide or halocarbons. Use water spray to keep fire-exposed containers cool. Approach fire from upwind to avoid hazardous vapors and toxic decomposition products.
Decaborane mixed with carbon tetrachloride is dangerously shock sensitive. It reacts slowly with air but when mixed with air or oxygen, it becomes highly flammable and may explode. It undergoes an explosive reaction with most oxidizing agents including halogenated hydrocarbons. It may give off toxic fumes of unburned material. When heated to decomposition, it emits toxic fumes of boron oxides. Incompatible with ethers; halocarbons; oxygen at 212F; dimethyl sulfoxide, most oxidizing agents, including halogenated hydrocarbons. It is corrosive to natural rubber, some synthetic rubbers, some greases, and some lubricants. Normally stable, but becomes unstable at elevated temperature and pressure. Hazardous polymerization may not occur. (EPA, 1998)
Use special powder, dry sand. NO other agents. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.
Personal protection: complete protective clothing including self-contained breathing apparatus. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

1) Ventilate area of spill. 2) For small quantities, sweep onto paper or other suitable material, place in appropriate container and burn in safe place (such as fume hood). Large quantities may be reclaimed ... /if not/ practical, dissolve in flammable solvent (such as alcohol) and atomize in suitable combustion chamber equipped with appropriate effluent gas cleaning device.
NO open flames. NO contact with halogenated compounds or oxidizing agents. Above 80°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Fireproof. Separated from food and feedstuffs, halogens and oxidants. Cool. Dry.Store in a cool, dry, well-ventilated location. Separate from oxidizing materials, halocarbons, and water.

Decaborane is a white crystals or colorless crystalline needles with an intense, bitter, chocolate-like odor. Used in rocket propellants, as a catalyst in olefin polymerization, as a rubber vulcanizer, to coat metals with corrosion resistant boron, in manufacture of plastics, as an oxygen scavenger; in mothproofing, in dye-stripping, as a reducing and fluxing agent, as a stabilizer and rayon delustrant.

May explode on heating or on contact with flames. Decomposes slowly at 300°C. This produces boron and flammable gas (hydrogen - see ICSC 0001). Decomposes on burning. This produces toxic fumes of boron oxides. Reacts slowly with halogenated materials and ethers. This produces impact-sensitive materials. Reacts explosively with oxidants. Reacts with water and moisture. This produces flammable gas (hydrogen - see ICSC 0001). Attacks natural rubber, some synthetic rubbers, some greases and some lubricants.
Stable indefinitely at room temperature.
FlammableDust explosion possible if in powder or granular form, mixed with air.DECABORANE forms impact-sensitive mixtures with halocarbons (carbon tetrachloride) or with ethers (dioxane). It ignites in oxygen at 100° C. When heated to decomposition it emits toxic fumes of boron oxides [Hawthorne, M. F., Inorg. Synth., 1967, 10, p. 93]. It may form an explosive mixture with dimethyl sulfoxide [Shriver, 1969, p. 209]. It reacts with amides, acetone, butyraldehyde, and acetonitrile at room temperature [Merck].

The aerosol is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in fatigue, hyperexcitability and narcosis. The effects may be delayed. Medical observation is indicated.
The substance may have effects on the central nervous system. This may result in fatigue, inability to concentrate and lack of coordination.
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
