Sodium borohydride, a versatile chemical compound widely used in various industries, has garnered attention for its unique properties and potential hazards. When it comes to flammability, sodium borohydride presents a complex scenario. While the compound itself is not inherently flammable in its solid form, it does pose significant fire and explosion risks under certain conditions. Sodium borohydride reacts vigorously with water, producing hydrogen gas, which is highly flammable and can ignite easily in the presence of an ignition source. This reaction makes sodium borohydride indirectly flammable and potentially dangerous if not handled properly. Additionally, the compound is moisture-sensitive and can spontaneously combust when exposed to air, especially in finely divided forms. Therefore, while sodium borohydride is not classified as a flammable solid according to standard definitions, its reactivity and the flammable byproducts it generates necessitate careful handling, storage, and usage protocols to mitigate fire and explosion risks in industrial settings.

Does sodium borohydride react with water to create flammable gas?
Sodium borohydride's reaction with water is a critical aspect of its chemical behavior and potential hazards. This powerful reducing agent undergoes a rapid and exothermic reaction when it comes into contact with water, resulting in the production of several compounds, including a highly flammable gas.
The Chemistry Behind the Reaction
When sodium borohydride interacts with water, it decomposes according to the following chemical equation:
NaBH4 + 2H2O → NaBO2 + 4H2
In this reaction, sodium borohydride (NaBH4) combines with water (H2O) to form sodium metaborate (NaBO2) and hydrogen gas (H2). The hydrogen gas produced is highly flammable and poses significant fire and explosion risks if not properly managed.
Implications for Safety and Handling
The generation of hydrogen gas from the sodium borohydride-water reaction has several important implications:
Fire Hazard
Hydrogen is extremely flammable and can ignite easily in the presence of an ignition source, even at low concentrations.
Explosion Risk
In confined spaces, the accumulation of hydrogen can create an explosive atmosphere.
Pressure Build-up
The rapid evolution of gas can lead to pressure increases in closed containers, potentially causing ruptures or explosions.
Spontaneous Ignition
Under certain conditions, the heat generated by the reaction can be sufficient to cause spontaneous ignition of the hydrogen gas.
These factors underscore the importance of proper handling and storage procedures for sodium borohydride, particularly in industrial settings where large quantities may be used or stored.
How should sodium borohydride be safely stored to prevent fire risks?
Given the reactive nature of sodium borohydride and its potential to generate flammable hydrogen gas, proper storage is crucial to prevent fire risks and ensure safety in industrial environments. Implementing robust storage protocols is essential for maintaining the stability of the compound and mitigating potential hazards.
