Toxic and Deleterious Substances Handler Qualification

This page explains when the qualification can be used, when a dedicated responsible person must be appointed, and whether a certificate is issued.

How the qualification is used

The qualification can be used when you take a position as a toxic and deleterious substances handler at a company or other organization. It is not granted to you as an individual qualification independent of that appointment.

When a responsible person must be appointed

Businesses that manufacture, import, or sell toxic or deleterious substances must appoint a dedicated toxic and deleterious substances handler. The appointed person is responsible for preventing health and hygiene risks caused by these substances.

Certificate issuance

The qualification is usable when you take the relevant responsible-person position at a company or other organization. A certificate proving that you are a toxic and deleterious substances handler is not issued.
