Abstract
A method for visibly marking an area contaminated with transformer oil or other organic liquid uses a marking composition that consists of a colorant held within a solid carrier material, the colorant being such as to effect a visibly perceptible change upon contact with the organic liquid. The carrier material may be an absorbent that permits delivery of the colorant through capillary action, or the colorant may be encapsulated by a cell-forming matrix material that interacts with the contaminating liquid to effect release.
