Key Elements of the HCS:
Training should occur at both initial assignment and whenever a new chemical hazard the employees have not previously been trained on is introduced into their work area. For training and HCS resources, click on the links below.
Safety Data Sheets
Employers are required to maintain safety data sheets (SDS) in the workplace for each hazardous chemical used. SDSs must be readily accessible and employees must have access to the SDS for the chemicals they are exposed to during all work shifts. The purpose of an SDS is to communicate the hazards of hazardous chemical properties. To ensure that all hazards are communicated, update SDSs as new versions become available and obtain SDSs for any new chemicals introduced into the workplace. In addition to updating SDSs, be sure to update the sites’ chemical inventory when new chemicals are introduced.
SDSs can be requested from UW-Madison Environmental, Health, & Safety at: https://ehs.wisc.edu/safety-data-sheets/.
The chemical manufacturer or importer must label all containers of hazardous chemicals in accordance with the Hazard Communication Standard and Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The label must contain the following information:
When chemicals are transferred from a labeled container into a secondary container, the secondary container can be labeled with the shipping label or a workplace label that contains the identity of the chemical and words, pictures, symbols, or combination thereof, which provides information on the physical and health hazards of the chemical. Never deface or remove any container labels and ensure labels and other forms of warning are legible, prominently displayed and in English.
