Physical safety considers the steps and regulations required to ensure that the plant and its surroundings are safe for the workers, visitors, and the environment. Environmental protection considers not only hazardous substances, but also the emission of electromagnetic radiation or noise. Digital safety considers the steps required to ensure that the communication networks and the associated devices cannot be hacked and used to create an unsafe physical situation.

This aspect is very important given the increasing legislative interest in making sure that confidential personal information remains confidential.
