Description of first aid measures
General adviceMost important symptoms and effects, both acute and delayed
Indication of any immediate medical attention and special treatment needed
Extinguishing media
Suitable extinguishing mediaSpecial hazards arising from the substance or mixture
Borane/boron oxides Sodium oxides
Not combustible.
Vapors are heavier than air and may spread along floors. May not get in touch with: Water
Forms explosive mixtures with air on intense heating. Ambient fire may liberate hazardous vapours.
Advice for firefighters
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.
Further information
Remove container from danger zone and cool with water. Suppress (knock down) gases/vapors/mists with a water spray jet. Prevent fire extinguishing water from contaminating surface water or the ground water system.
NFPA 704
| HEALTH | 2 | Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine) | |
| FIRE | 1 | Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia) | |
| REACT | 2 | Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water (e.g. white phosphorus, potassium, sodium) | |
| SPEC. HAZ. |

Waste DisposalThe solid or its solution is dissolved or diluted inlarge volume of water. Diluted acetic acid oracetone is then slowly added to this solutionin a well-ventilated area. Hydrogen generatedfrom decomposition of borohydride shouldbe carefully vented out. The pH is adjustedto 1. The solution is then allowed to stand forseveral hours. It is then neutralized to 7, andthe solution is then evaporated to dryness.The residue is then buried in a landfillsite approved for hazardous waste disposal.
