Outline of reasons and objectives
Thermal spraying is a process during which a coating is applied at high temperature and at high speed onto a metal object, for the purposes, for example, of producing a surface that is more resistant to corrosion…

Outline of reasons and objectives
Exposure to bioaerosols (bacteria, moulds, and sub-products or fragments of micro-organisms) present in the air at workstations has been established in numerous occupational sectors. In certain employees…

In France, nearly 800,000 employees are potentially exposed to diesel fumes, which have been identified as the primary source of exposure to a carcinogenic. Prevention of exposure to this pollutant in testing centres for testing vehicle safety…

Some authors highlighted that during the filtration of ultrafine particles, the deposit is essentially located in the first layers of the granular bed. Thus, only a small depth is useful thereby reducing both the operation time between each unclogging…

Quantifying semi-volatile organic aerosols in workplace air is a critical step in assessing employee exposure to these types of aerosols. Indeed, numerous organic compounds coexist both in particulate and gaseous form. However, the sampling…

Thermal spraying (TS) is a surface treatment process, which enables different types of material (metals, metal alloys, ceramics and even plastics) to be deposited on various substrates. The coating product, in wire or powder form, is melted by a heat…

By spraying judiciously placed drops of water, you can reduce dust emissions at source or purify polluted air. But the use of this preventive measure cannot be improvised: it requires careful design to be truly effective, and can give rise to numerous…

Polycyclic Aromatic Hyrocarbons (PAHs) are chemical compounds that are sometimes highly toxic, or indeed that are considered by some to be proved carcinogens. A variety of sectors of activity cause PAH emissions: incineration, pyrolysis, diesel…

In this work, we propose a method based on simultaneous size-integrated measurements of two particle concentrations (number and lung-deposited surface area, CNC/NSAM), and on the estimation of the average size of potentially inhaled particles…

Ultrafine particles are generated by many manufacturing processes: surface processing and coating (thermal spraying ...), machining (drilling, rectification ...), combustion welding, and cutting of metals etc...
The development of suitable protection…
