Fire means uncontrolled burning that causes material damage or endangers human lives, which is how it differs from fire. There is no activity that is free of fire hazards, and they are especially common in the construction industry. Proper selection of building materials, building elements and structures with regard to their resistance to fire hazards and proper design of the building meet the basic requirements of fire protection of buildings. Technological processes and substances used in performing a certain activity, the method of performing work, stored substances and the size of the building are important for hazard assessment and adequate and timely assessment and adoption of fire protection measures. Preventive fire protection measures are important in preventing the outbreak of fires, and in the event of a fire, they are important for the general safety and health of workers, the protection of property and the environment. The Fire Protection Act is the basic legal document on construction fire protection measures.
