He stored the oily rags inflammably near the furnace, dangerously increasing the risk of a fire.

The laboratory posted charts comparing the inflammabilities of various solvents to ensure safe storage.

During the 18th-century experiments, chemists collected inflammable air over water and watched it ignite.

The lab selected materials for the new cabinets based on their non-inflammability.

The chemist carefully stored the sample of inflammable cinnabar in a sealed cabinet to prevent accidental ignition.
