Recently we came across a 2008 issue of the Journal of Occupational and Environmental Hygiene.
In it, an engineering case study described NIOSH research into the effect of local exhaust ventilation on the control of engineered nano particles.
Because the topic connects engineered nanoparticles with local ventilation, many Sentry Air staffers were interested in the article.
When they saw Figure 1, they became downright enthusiastic about it. Why? Because it shows the unit that provided the local ventilation – and it’s our Model 300 portable fume extractor.
Study offered no product-specific recommendation, but…
We’ve known our welding fume extractors are very effective at capturing combustion-derived nanoparticles.
The behavior and toxicity of airborne engineered nanoparticles continue to be researched, posing an interesting question for us.
Can we capture engineered nanoparticles with the same technologies and techniques?
Results of this study suggest we can and we do.
The study’s acknowledgement
The authors conclude that fume extraction at the source can be highly effective in controlling the emissions of engineered nanomaterials to prevent their spread.
They say, “This finding, coupled with the current use of PPE, appears to be an acceptable method of reducing the potential for worker exposure.”
