This article presents the most common hazards present when precast concrete is manufactured and used. An analysis of the occupational activities at different workstations has shown that the greatest risk is associated with exposure to mechanical, thermal and chemical factors. On the basis of a classification of existing hazards, this article presents recommendations for how protective gloves should be selected.

This is the final push for the new Occupational Safety & Health standard ISO 45002 Occupational health and safety management systems – Requirements with guidance for use which has been under preparation since 2013. It is widely expected for the new standard to be published in 2018 at the latest. The adjustment of the OSH Management Systems to the requirements of the new standard will take a thorough analysis of the already implemented processes and management practices. The article presents a general structure of the OSH Management Systems in accordance to the new standard and underlines requirements specific to chosen OSH management processes – either broadened or refined in relation to requirements formed in the presently existing standards.

One of the problems of the modern cosmetic industry consists in the need to ensure the required microbiological purity of cosmetics, and consequently the need to include preservatives in cosmetic formulas. This article discusses the most commonly used preservatives and mechanisms of their action, as well as the legal provisions on preservatives in cosmetics. It also reports on the adverse effects of preservatives, which may pose a hazard not only to workers involved in manufacturing cosmetics, but also to their users, which means practically the whole population.

One of the functions of glass partitions, commonly used in construction, is the reduction of noise. These partitions are characterized by low sound insulation for low frequencies. This article presents the concept of a multi-channel active noise control system that enables the reduction of low-frequency noise transmitted through the glass partition. The system is based on a neural network with the modified version of the backpropagation algorithm using a round robin algorithm. The structure and principles of the system are discussed and the results of its simulations are presented.
