Types of Containers
Container labeling is one of the most effective methods for communicating the physical and health hazards associated with chemicals used in the workplace. Proper labeling ensures that all employees can quickly identify hazardous materials and take appropriate precautions when handling them.
Example:
A large stationary tank located outdoors with access steps represents one type of container requiring proper labeling.
The information displayed on a label will vary depending on the type of container and how it is used. Under OSHA’s Hazard Communication Standard (HCS), specific labeling requirements apply to different types of containers.
In this module, we will review labeling requirements for the following container categories:
- Shipped (Primary) Container Labels – These appear on containers provided by chemical manufacturers, importers, or distributors. They must include all required elements under the HCS, such as product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information.
- Workplace (Secondary) Container Labels – These are applied by employers to containers used in the workplace when chemicals are transferred from their original containers. Labels must identify the product and convey general hazard information.
- Stationary Container Labels – These are used on large, fixed tanks or process vessels. The employer must ensure that the hazard information is clearly marked, either directly on the container or posted near it.
- Portable Containers – Containers used temporarily by one employee within a single work shift do not require labels, provided the contents remain under that employee’s control and are not left unattended.
