Each container of hazardous chemicals leaving the workplace must be labeled, tagged, or marked with the following:
- Product Identifier: The name or number used for a hazardous chemical on a label or in the SDS. It provides a unique means by which the user can identify the chemical. The product identifier used must permit cross-references to be made among the list of hazardous chemicals required in the written HazCom program, the label, and the SDS.
- Pictogram: A symbol plus other graphic elements, such as a border, background pattern, or color that is intended to convey specific information about the hazards of a chemical. Each pictogram consists of a different symbol on a white background within a red square frame set on a point (i.e., a red diamond).
- Signal Words: A single word used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label. The signal words used are “danger” and “warning.” “Danger” is used for the more severe hazards, while “warning” is used for less severe hazards.
- Hazard Statement: A statement assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical, including, where appropriate, the degree of hazard.
- Precautionary Statement: A phrase that describes recommended measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling of a hazardous chemical.
- Supplier Information: Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party.
Once the hazard classification is completed, the chemical’s hazard class and category will dictate the pictogram, signal word(s), hazard statement(s), and precautionary statement(s) that must be used on the label, and which must appear on the SDS.
