| PARTICULATE CONTAMINANTS: SOURCES OF CONTAMINATION | ||
Recent studies suggest that with the use of improved methods, training, and design, the percentage of contaminants from personnel can be driven down to the 5 - 10% range. Unfortunately, even this good news has had some unintended consequences, as some workers become complacent about their cleanroom entry protocols. As a result, personnel wearing particle-shedding products (which we’ll discuss later in the course), may be driving the contamination rates from personnel back up to 35% range, and even beyond. |
