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 .
Most important symptoms/effects, acute and delayed
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)
Indication of immediate medical attention and special treatment needed, if necessary
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
SECTION 5: Firefighting measures
Suitable extinguishing media
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.
Specific hazards arising from the chemical
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)
Special protective actions for fire-fighters
Use special powder, dry sand. NO other agents. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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.
Environmental precautions
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.
Methods and materials for containment and cleaning up
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.
SECTION 7: Handling and storage
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities

SECTION 10: Stability and reactivity
Reactivity
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.
Chemical stability
Stable indefinitely at room temperature.
Possibility of hazardous reactions
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].
Conditions to avoid
