Industrial large-scale urea production creates a number of hazards due to equipment and machine failures as well as service errors. Failures can cause material, environmental and human losses. The work presents the assessment of safety hazards and failure effects for selected emergency scenarios of Mitsui - Toatsu's urea synthesis reactor. A fragment of the process implemented in the synthesis node was covered by HAZOP (Hazard and Operability Study), and the critical points, from the security point of view, were identified. Several emergency scenarios for various types of failures and various effects are presented. The analyzed contingency scenarios include: blocking the valve on the outflow from the reactor and leaks caused by corrosion resulting from the maintenance of improper technological parameters of the process. The work suggested the need for new security measures and modernization of the installation by using the safety function for the selected critical point. The hazards analyzed and the contingency scenarios developed are essential for risk assessment and its possible reduction.

Safety engineering has become a challenging and rewarding career field in the present day age of rapid technological and scientific advances. But how to raise student’s awareness regarding the legal and regulatory requirements introduced by safety organizations and government agencies? The aim of this paper is to show how successful cooperation between professionals in the field of safety engineering, especially functional safety and experienced university language teachers can boost student motivation and inspire them to face the social and industrial needs of changing business environments. We will try to prove that a tailor-made course provides students with efficient information about the subject, source material and vocabulary from the field of safety engineering. It will also enable students to use knowledge to respond to hazards and accidents. It will teach them to take independent decisions in emergency situations and prepare them to feel comfortable in the global business.
