Behaviour-Based Safety (BBS) is a method used to popularize safe behaviors of employees at work. The aim of the study described in the article was to verify the hypothesis that a systematic process of observation of the employee in the workplace will lead to an increase in behavior’s safety and a reduction of the number of risky behavior. The study encompassed a manufacturing company in the food industry with 500 workers on payroll. The analyzed data had been collected during the 8 months long observations in the framework of the BBS program.

 As expected, the analysis of the ratio of identified risk behaviors indicated a decreasing trend, while the rate of safe behaviors a pronounced increasing trend. The analysis also enabled selection of positions where risky behaviors are taken significantly more often. The results also indicate an increase in employees awareness of risky behavior and the results of risks. The results indicate the reasonableness of the implementation of programs of BBS in the organization.

In cement factories belonging to Grupa Ożarów system solutions in OSH management have been implemented for many years. However, due to the fact of various shortcomings related to disregard for the safety and health at work still present a decision was made to implement a comprehensive solution aimed in increasing employee awareness and sensitizing them on dangerous behavior – both their own and their colleagues.

The article presents the problem of exploitation of refrigeration systems and heat pumps in terms of refrigerant emissions to the atmosphere. These substances are responsible for destroying the ozone layer, and to a large extent for the greenhouse effect. Safe exploitation of devices containing refrigerants aims to reduce their emissions and reduce energy consumption to propel them.

The article presents a definition of indicators ODP and GWP. An analysis of the index TEWI for water source heat pump operating period of 10 years and interpreted its individual components was made. The calculations were performed in regard of four refrigerants: R-404A, R-407C, R-410A and R-600a.

The paper presents the rules guiding early retirement due to working conditions in selected EU Member States and how they compare to the solutions applied in Poland.
