The paper discusses the enhancement of inherent safety by index methods. The aim is to study, how well the safety index methods can evaluate inherent safety compared to expert evaluations and Dow Fire and Explosion index values. Studies on four levels of scope from process concept selection to equipment design were done and correlations between indices and expert values calculated. It was found...

Since the Second World War the consumer behaviour in developed countries changed drastically. Primarily there existed the demand for sufficient food after a period of starvation, afterwards the desire for higher quality was arising, whereas today most people ask for safe and healthy food with high quality. Therefore a united approach comprising consistent standards, sound science and robust con...

Main components of the problem of chemical safety, their role and aims as well as their mutual relations are presented. Need to create a register of chemical compounds and necessity to set up an information centre which would help functioning the whole system are justified. Risk assessment is believed to be the main aspect of cognitive activities aimed at determining the probability of occurren...

Barriers are used in various forms to assure the safety of chemical plants. A deep understanding literature related barriers is essential tackle challenges improving their design and management. This paper first provides an overview history development barrier concept. Subsequently, this elaborates a systematic review definition, classification, evaluation, performance assessment, management pr...

In past decades, gas sensors based on the metal oxide semiconductors (MOSs) have been studied in diverse field for wide applications. A gas sensor is a device that can be used to detect various gas such as ethanol, LPG, CO2 and CO gases etc. The gas sensors based on MOSs such as SnO2, TiO2, WO3, ZnO, Fe2O3, and In2O3 have an important role in environmental monitor‐ ing, chemical process control...
