Scunthorpe's furnaces produce molten iron by splitting rocks containing iron ore in a chemical reaction that requires intense heat.

He splashed and poured liquid thinners over paint, causing chemical reactions to burn holes in the surface — “Ozone Paintings,” he called them.

In July, El Sobrante managers informed the South Coast Air Quality Management District that a chemical reaction brewing inside the landfill was causing broiling temperatures and producing toxic sulfur pollution, according to air district records.

Lithium-ion battery fires are notoriously hard to extinguish because the use of water can trigger a chemical reaction that causes more batteries to ignite.

Once the fire began spreading, firefighters were not able to use water, because doing so can trigger a violent chemical reaction in lithium-ion batteries, potentially causing more to ignite or explode.
