Safety management in non-Seveso establishments in control of major accidents - necessary management procedures (1)
Jerzy S. Michalik, Agnieszka Gajek

As a result of research carried out in 2008-2010 it has been found that non-Seveso establishments pose a relatively greater risk of a major accident, than lower- and upper-tier establishments. As demonstrated by numerous inspections of the State Labour Inspectorate (PIP), the state of safety management in the context of control of major accidents in non-Seveso establishments is quite insufficient. Taking into account those circumstances, proposals were developed for elements and procedures of safety management systems concerning prevention of major accidents and limitation of their effects in non-Seveso establishments; they take the form of recommendations presented in this publication.

Bożena Smagowska, Witold Mikulski

This paper presents the method and results of laboratory tests conducted to determine the influence of ultrasonic noise on cognitive skills and the psychomotor capability of the human body. The method was based on the change in mental capacity of subjects exposed to ultrasonic noise in such function as reflexes, observation skills, attention and work output, subjective estimation of mood and tiredness of the subjects. Those functions were assessed with indicators from psychological tests and the basis of questionnaires. A preliminary criterion of annoyance of ultrasonic noise was developed (in the third band 31.5 kHz).
