Hydrogen peroxide doesn’t qualify as a flammable material and lacks a flash point; hence, it’s not ignitable via a lighter.
Yet, hydrogen peroxide becomes hazardous when heated, as it decomposes swiftly at elevated temperatures, generating an abundance of oxygen, which significantly fuels the fire.
Combustion is inherently an intense oxidation-reduction process. Moreover, hydrogen peroxide serves as a potent oxidizer, endowed with robust oxidizing capabilities.
It mustn’t be stored with typical reducing substances due to its propensity to engage in explosive and heat-releasing redox reactions with such materials.
