Under the Labour Protection Act (ArbeitnehmerInnenschutzgesetz, ASchG), employers have to obtain a permit from the competent authority for workplaces presenting particular hazards . Such a workplace permit is not necessary if some other law imposes such an obligation on employers, i.e. under the industrial code, the Act governing Pharmacies (Apothekengesetz) or the Railway Act (Eisenbahngesetz).
