In yesterday’s article, we looked at the labeling requirements for solid materials, specifically, when a solid material is an “article” that does not require labeling and when it is a potentially hazardous chemical that must be labeled. Today, we’ll look at other unusual labeling situations that may arise and how to handle them.
Today’s workplace uses thousands of chemicals, many of which are hazardous. The resources in this section will help guide you in the safe and legal identification, storage, transport, and use of these chemicals, and in making sure that your employees right to know how to be safe around such substances is provided, as required by law.

When we think of chemical labeling, we tend to think of “ordinary” situations—gallon jars of sulfuric acid sporting OSHA’s new pictograms, or bags of insulation with their hazard labels prominently displayed. But hazardous chemicals don’t always come in what we think of as “ordinary” containers, nor do they stay there—they are, after all, intended for use. How should you address labeling under these unusual circumstances?
Methylene chloride (also called dichloromethane) is a solvent with many uses, including paint stripping, polyurethane foam manufacturing, and cleaning and degreasing. You might not think that a chemical you can buy at your local home improvement store for use at home would be all that dangerous, but don’t be fooled. Methylene chloride is hazardous enough that it is covered by one of OSHA’s substance-specific standards, 29 CFR 1910.1052.
