The Safety Data Sheet of chemical substances as a tool to communicate the risk

Presentation of the course:

The main regulations for companies that deal with chemical substances are REACH and CLP. While the main purpose of REACH is the evaluation of the risk for human and environmental health, for CLP is the communication of the hazard throughout the supply chain. The main tool to achieve this goal is the Safety Data Sheet.

It will also be underlined which elements must be taken into consideration in writing a Safety Data Sheet.
