Reactivities and Incompatibilities
A mixture /of sodium hydrogen carbonate, carbon and water/ was being stirred and steam heated when power failure interrupted stirring, and heating was turned off for a hour before power was restored. When stirring was restarted, the hot contents of the pan erupted immediately. Carbon dioxide is evolved from warm aqueous solutions of the base, and absence of stirring and presence of the carbon adsorbent would lead to non-equilibrium retention of the gas, which would be released instantaneously on stirring.
Several cases of spontaneous ignition after exposure to air of fine coke particles removed from filter strainers on a petroleum refinery furfural extraction unit have been noted. This has been associated with the use of sodium hydrogen carbonate (bicarbonate) injected into the plant for pH control, which produced a pH of 10.5 locally. This would tend to resinify the aldehyde, but there is also the possibility of a Cannizzaro reaction causing conversion of the aldehyde to furfuryl alcohol and furoic acid. The latter, together with other acidic products of autoxidation of the aldehyde, would tend to resinify the furfuryl alcohol. Pyrolysis gas-liquid chromatography (GLC) showed the presence of a significant proportion of furfuryl alcohol-derived resins in the coke. The latter is now discarded into drums of water, immediately after discharge from the strainers, to prevent further incidents. /2-Furaldehyde (Furfural): sodium hydrogen carbonate/
A self-propagating reaction can occur when ... sodium bicarbonate- ... based dry chemical extinguishing agent is mixed with monoammonium phosphate dry chemical extinguishing agent. Moisture will accelerate reaction. Products are water, ammonia, carbon dioxide and various solid substances. In a fire extinguisher the pressure developed will blow out the valve.
Sodium-potassium alloy undergoes a violent reaction with certain extinguishing agents: water, sodium bicarbonate, carbon tetrachloride. /Sodium-potassium alloy: water/
Protective Equipment and Clothing
The substance is mildly irritating to the eyes.

Reported in EPA TSCA Inventory.

Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
