INTRODUCTION The evaluation of occupational risks and potential threats to the safety and health of employees is prepared with the aim to identify sources of danger and risks, evaluating the severity of the risk and determining measures to eliminate or reduce the risk. The estimate of the likelihood with which the considered risk can really occur is determined according to a likelihood estimate scale by 1 to 5 in an ascending order, where the rate, level of criteria of each risk is included. The assessment and evaluation of the resources of risk is performed using the following specifications: A. Probability of onset and existence of risk 1. Occasional 2. Improbable 3. Probable 4. Very probable 5. Permanent B. Possible consequences of threat 1. Injury without inability to work 2. Absence injury (with inability to work) 3. More serious accident (requiring hospitalization) 4. Serious injury and injury with permanent aftereffects 5. Fatal accident In determining measures to prevent occupational hazards and risks, the assessor derives from general preventive principles, which include: a) elimination of risks at the source of their origin, b) reduction of origination of risks, c) adapting of working conditions to the needs of employees, d) replacement of physically strenuous work and work in difficult working conditions with new technological and work procedures, e) preferential application of means of collective protection against risks over means of individual protection, f) establishing of appropriate guidelines to ensure safety and health at work. Measures in case of fire and evacuation of employees are determined by the fire protection documentation according to the requirements of Act No. 133/1985 Coll. on fire protection, as amended, and implementing Decree of the Ministry of the Interior of the Czech Republic No. 246/2001 Coll. Evaluation of occupational risks and possible threat to the safety and health of employees captures the current situation.
