CONTROLLED ENVIRONMENTS APPAREL SELECTION GUIDE
When it comes to working in a broad range of controlled environments, specifi ers have many product options from which to select. Th e process to understand which option matches a given environment can be confusing. DuPont has tried to help reduce some of that burden by providing a complete line of products and information to help guide specifi ers through their selection process.
To get the most out of your cleanroom apparel, it is necessary to understand where each product can be used. To provide a quicker overview of our products and where they are intended for use, we developed the simple guide below. Our goal is to provide the appropriate DuPont product that is suitable for a given environment or hazard.

Nuisance static. Antistatic performance may be reduced for sterile products. Barrier properties may be compromised through use. * Tyvek® IsoClean® (Option Code CS, DS and MS) garments are most typically considered for use in GMP A-D, ISO Class 5-8. However, use in ISO Class 4 and 9 environments
may also be considered depending on the needs of a particular application. In all cases, garment choice depends on evaluation of, among other attributes, garment design and processing, as well as the needs of specific applications. Clean-processed and bound seam garments offer the highest level of contamination control and should be used in more critical applications. Sterile garments are available if required. It is the end-user s responsibility to determine the appropriate garment for a given application.

Tyvek® provides an inherent particle barrier and durability, and is low linting. Clean-processing and bound seams should be considered for more critical environments.
Non-hazardous, dry particles ● ● ● Tyvek ® provides an inherent barrier against small particles.
Bound seam garments offer a higher level of protection than serged seam garments.
Hazardous powders Notice: DuPont Controlled Environments garments should not be used in potentially explosive or flammable environments.
● ● ● Use bound seamed garments when working with hazardous powders. Hazardous liquid splash Examples: organic solvents, caustics
Please refer to our Tychem® product line for liquid and vapor chemical protection.
Electric arc, industrial fire hazard, welding Do Not Use
Please refer to Nomex® for flame-resistant apparel. Controlled Environment garments are not suitable for firefighting activities, nor for protection from hot liquids, steam, molten metals, welding, electric arc or thermal radiation.
