Hearing conservation in the primary aluminium industry

BACKGROUND Noise-induced hearing loss has been an intractable problem for heavy industry. AIMS To report our experience in reducing the incidence of age-corrected confirmed 10 dB hearing shifts (averaged over 2, 3 and 4 kHz) in employees in the primary aluminium industry in Australia over the period 2006-13. METHODS We analysed annual audiometric data to determine the number of permanent he...

Role and Characterization of Surfaces in the Aluminium Industry

Aluminium is used extensively in the transportation, architecture, electronic and packaging industries. Aluminium presents particular characteristics such as low density, high ductility and a highly protective natural oxide film. However, formability, corrosion resistance, weldability, adhesion and surface aspect depend on the chemistry and microstructure of the metal surface. Properties of par...

Respiratory pathology pattern of aluminium industry workers in Russian Arctic

The aim of the study is to investigate risks, prevalence, clinical forms of chronic bronchopulmonary diseases (CBPD) in aluminum workers and assess whether asthma and other respiratory conditions occur excessively among pot workers. The survey of 479 workers at Kandalaksha aluminum smelter has shown that the most prevalent respiratory disease is chronic bronchitis (CB) detected in 13,4-17,0 % o...

Aluminium dross-based insulating and exothermic materials for metallurgical industry

In the conducted investigations, aluminium dross, i.e. solid waste formed in the production and recycling of aluminium, was used as one of the basic raw materials to obtain a material characterised by insulating and exothermic properties, applied to heat riser heads in the process of iron or steel casting. The product was obtained by filtrating the slurry. In the raw mix, aluminium dross played...
