Airborne particle deposition in cleanrooms: Calculation of product contamination and required cleanroom class

This is the third and final article in a series that discusses the deposition of airborne particles onto critical surfaces in cleanrooms. This article explains a method for calculating the amount of particle or microbe-carrying particle deposition onto critical cleanroom surfaces, such as product, and a method for calculating the airborne particle cleanliness class, or airborne microbial concen...

Could we predict airborne Aspergillus contamination during construction work?

BACKGROUND Aspergillus fumigatus is a major opportunistic pathogen causing nosocomial infection. Hospital outbreaks of invasive aspergillosis have been associated with demolition and building construction. This study was designed to examine the impact of meteorologic factors and different periods of work on outdoor fungal airborne concentrations. METHODS The study was conducted at Necker Enfa...

Geltape method for measurement of work related surface contamination with cobalt containing dust: correlation between surface contamination and airborne exposure.

OBJECTIVES The geltape method is a new method for optical measurement of total amount of dust on surfaces. The objectives were to study the potential applicability of this method to measurements of work related cobalt exposure during painting of plates with cobalt dye. METHODS Consecutive series of work related geltape prints were taken from surfaces inside and outside the ventilation cabins ...

Airborne Contamination in Dentistry

62 INTERNATIONAL DENTISTRY SA VOL. 9, NO. 1 infectious organisms. These fluids are projected into the air by coughing, sneezing and general exhalation. In a dental surgery, however, this process is exacerbated significantly by the use of the high-speed instruments such as ultrasonic scalers and drills (Figures 1 and 2). During treatment, several thousand droplets are aerosolized. Whereas the la...
