Pursuant to Article 89 of the Constitution of the Republic of Croatia, the President of the Republic promulgates by a decision the laws passed in the Croatian Parliament. In order to implement occupational safety and fire protection, laws were passed, the Occupational Safety and Health Act whose purpose is to systematically improve the safety and health of workers and persons at work, prevention of injuries at work, occupational diseases and other work-related diseases on fire protection, which regulates the fire protection system with the aim of protecting the life, health and safety of humans and animals and the safety of material goods, the environment and nature from fire, with socially and economically acceptable fire risk. Fire protection is of special interest to the Republic of Croatia. The Occupational Safety and Health Act transpose into the legal order of the Republic of Croatia the Directives of the European Union relating to the improvement of safety and health at work. The Occupational Safety and Health Act prescribes the responsibility of the employer for the organization and implementation of occupational safety in all parts of the organization of work and in all work procedures, and to determine the organization of the implementation of occupational safety in regulations or other acts. For this purpose, the Employer is obliged to determine and perform occupational safety activities in accordance with the risk assessment, the state of occupational safety and the number of employees. Depending on the risks, activities and number of employees, a special ordinance prescribes the types, levels of education and the number of occupational safety experts with whom the Employer is obliged to contract with one or more occupational safety experts. For the purpose of implementing measures and organization of fire protection for buildings, construction parts and other real estate, these areas are classified by the decision of the Minister into one of the four prescribed categories of fire risk. Depending on the classified category of fire risk, the owners or users of the same buildings are obliged to organize a fire protection service and hire an employee in the service or hire an employee in charge of performing fire protection activities and improving the state of fire protection. In the implementation of occupational safety and fire protection, the employer must inform workers about all risks and conduct appropriate training.
