The businesses it reaches
Decreto-Lei n.º 301/2000, de 18 de novembro, regulates the protection of workers against risks linked to exposure to carcinogenic or mutagenic agents during work. It reaches employers whose activities bring workers into contact with such agents, including construction firms, manufacturing plants, waste producers, laboratories, and cleaning and maintenance service providers. The toolkit sets out the duties this law places on those employers in eight working files.
Each working file groups the instrument's obligations by subject into phases of open questions that the business answers from its own records. The toolkit carries the statutory text exactly as the authority wrote it beside each duty. The sections are served through a connector inside Claude, and the documents that come back are dated compliance reports the business keeps in its own file.
The files cover risk assessment, substitution and reduction, exposure risk reduction, safety and health at work, health surveillance, and the remaining duties on information, training, and record keeping. The toolkit never gives advice and never presents a perspective; it carries what the authority wrote, organised.
