Hazard Symbols & Labels
For recognition purposes, the hazard symbols in the catalog are from Title 49 of the Code of Federal Regulations (CFR), part 172 (DOT), yet the criteria used for assigning hazard symbols is primarily from the American National Standards Institute (ANSI) standard Z129.1 for Hazardous Industrial Chemicals Precautionary Labeling. The hazard symbols in the catalog are provided only as a guide for quick recognition of the acute hazards associated with our chemicals. They are not to be used in lieu of reading the Material Safety Data Sheet (MSDS) nor do they necessarily reflect correct DOT markings. Please refer to 49CFR for correct DOT markings.
