Particulate Clouds: Dusts, Smokes and Mists

Aerosols – Dusts, Fumes and Mists

Instead of the definitions for total dust and fine dust which were used in the past, from 1996 the new internationally agreed conventions for measuring concentrations of particles (DIN EN 481, 1993) are to be used in the establishment of MAK values. Therefore the definitions of particle fractions and the methods of measuring them have been modified in line with this convention and also extended...

Electrostatic Ignition Hazards Associated with Flammable Substances in the Form of Gases , Vapors, Mists and Dusts

The paper deals with the assessment of the electrostatic ignition hazards when flammable gases, liquids or powders are handled and processed in industry. It reviews the present state of knowledge in this field based on information available from literature, codes of practice and guidelines. In a short introduction the prerequisites for the ignition of a flammable atmosphere are described. The s...

Respiratory Diseases Among Dust Exposed Workers

Airborne contaminants occur in the gaseous form (gases and vapours) or as aerosols. Aerosols may exist in the form of airborne dusts, sprays, mists, smokes and fumes. In the occupational setting, all these forms may be important because they relate to a wide range of occupational diseases. Airborne dusts are of particular concern because they are well known to be associated with classical wides...

Talking About The Smokes

Design, setting and participants: The Talking About The Smokes project used a quota sampling design to recruit 1392 daily smokers from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait from April 2012 to October 2013. These were compared with 1010 daily smokers from the general Australian population surveyed by the International Toba...
