SECTION 10: STABILITY AND REACTIVITY
10.1.
Reactivity
Stable in use and storage conditions as recommended in section 7, and as clarified the mixture is eventually
intended a fire-extinguishant.
In extreme circumstances the substance could decompose on exposure to temperature rise and release of
oxygen. On burning it might release toxic and corrosive gases/vapors (nitrous vapors) in the direct vicinity of the
initiation.
Could be (in extreme conditions) violent to explosive reaction with many compounds like organic materials,
combustible materials, (some) metals and their compounds and with (strong) reducers. Reacts with (some) acids
and could then release of toxic and corrosive gases/vapors (nitrous vapors).
10.2.
Chemical stability
Stable under normal conditions (working environment).
10.3.
Possibility of hazardous reactions
The product reacts with combustible materials and increases combustion even in the absence of air. Reacts with
many compounds e.g.: with organic material, with combustible materials, with (some) metals and their
compounds and with (strong) reducers. Reacts with (some) acids: release of toxic and corrosive gases/vapors
(nitrous vapors).
10.4.
Conditions to avoid
Avoid high temperatures. Prevent moisture contact.
Also avoid direct sunlight, sources of heat, incompatible materials, open flame, and sparks.
10.5.
Incompatible materials
Keep substance away from: strong acids, strong bases and oxidation agents, combustible materials, reducing
agents, organic materials.
10.6.
Hazardous decomposition products
Mainly Nitrogen oxides and oxygen could be released.
On heating/burning, release of toxic and corrosive gases/vapors nitrous vapors will occur. Decomposes on
exposure to temperature rise and then release oxygen.
Reacts with (some) acids: release of toxic and corrosive gases/vapors: nitrous vapors.
