Highly concentrated sources of oxygen promote rapid combustion. Fire and explosion hazards exist when concentrated oxidants and fuels are brought into close proximity; an ignition event, such as heat or a spark, is needed to trigger combustion. Oxygen is the oxidant, not the fuel, but nevertheless the source of most of the chemical energy released in combustion. Combustion hazards also apply to compounds of oxygen with a high oxidative potential, such as peroxides, chlorates, nitrates, perchlorates, and dichromates because they can donate oxygen to a fire.
What is needed to make combustion happen? Combustion is caused by an oxidant and a fuel. What role does oxygen play in combustion? Peroxides, nitrates and dichromates are examples of what type of compounds? Although not a fuel  ___ is the chemical compound the generates the most occurrence of explosions. What is a spark or heat to the progress of a fire? Rather than the fuel, what is oxygen to a fire? What can concentrated oxygen produce? What does oxygen the basis for in combustion? What other sources of high oxidative potential can add to a fire?
