DUPONT™ SAFESPEC™ Terms of Use
Product Selector Agreement
The following information must be read and accepted by the user before proceeding.
The DuPont™ SafeSPEC™ Product Selector Tool (“Tool”) is intended to assist in choosing protective clothing styles for particular applications and does not replace the judgment of a qualified safety professional or industrial hygienist. Additional personal protective equipment (“PPE”), such as but not limited to: respiratory, eye, head, foot, and hand protection, may be required. Supplying the proper hazard/chemical and exposure information for your hazard scenario is critical in order to obtain suggestions of possible garment options for your consideration. Inaccurate information could result in improper suggestions. Since there are other factors involved which could affect the final PPE decision and may not be considered in this Tool, the final decision on protective clothing selection is the responsibility of the buyer, safety professional, industrial hygienist and end-user. DuPont de Nemours, Inc. or its affiliates DISCLAIM ANY RESPONSIBILITY OR LIABILITY FOR ANY INFORMATION OR SUGGESTIONS PROVIDED BY THE TOOL OR THE USE THEREOF.
WARNING / CAUTION
There are uses, environments and chemicals for which any garment will be unsuitable. It is the responsibility of the user to review available data and verify that the garment selected is appropriate for the intended use and meets all specified government and industry standards.

Hazard Concentration information
Please read following
- You have selected a chemical that has been tested at multiple concentrations. All concentrations will be displayed on the next page so that you can review breakthrough times for each concentration.
- Please review FAQs if your hazard concentration is lower or higher than the tested concentrations
Need Help?
- If you see your CAS number in the drop down list, make sure you are selecting the hazard from the drop down list before clicking "Add to List".
- If you do not see your CAS number listed, check the number and try again or you may want to try Guide.

Flammable Environments
WARNING
If any of the following apply:
- A fire or electric arc is actively present in the work environment
- The work environment contains an uncontrollable flammable material between the Lower Explosive Limit (LEL) or Lower Flammable Limit (LFL) and the Upper Explosive Limit (UEL) or Upper Flammable Limit (UFL)
- The work environment has been subject to a breach or loss in containment of flammable material (flammable liquids, flammable vapors or combustible dusts)
- There is an uncontrolled fuel source available in the work environment (that may or may not have encountered an ignition source yet)
Please consider fire fighter PPE (personal protective equipment). Read more.
If none of these conditions apply but FR clothing is required in your working environment, close this box and proceed to the next question. Only fabrics that provide both chemical resistance to the hazards you have listed and protection during escape from a flash fire will be considered for your hazard scenario.

Your hazard scenario did not produce any results. May we suggest:
- If you are searching multiple hazards at one time, try breaking your search into separate hazards by either creating a new scenario or unchecking Hazards in the pane to the left. SafeSPEC™ is trying to find one garment that can be used for all of your hazards. You may need to consider more than one garment.
- If you have a liquid or vapor chemical hazard, try searching the Chemical Resistance Database. This database will show you permeation data for all of the fabrics tested against a given hazard. Once you are able to determine a suitable fabric, you will have the flexibility of selecting a suitable garment design and seam construction yourself.
- If you answered "yes" to the question that you are working in an environment that requires flame resistant clothing, please note that although DuPont has several garment options for scenarios involving possible industrial fire or electric arc exposures as well as chemical exposure hazards, these garments may not have been tested against the specific chemical hazard(s) that you have selected or may have breakthrough times lower than your intended work duration. If possible, try to mitigate the need for flame resistant clothing by implementing engineering controls, work practices and administrative controls before resorting to protective clothing. Additionally, try breaking your search into separate hazards as suggested above in order to find garment options to meet your needs.
- If you selected "localized to the feet" for the direction of exposure question, you may want to consider chemical resistant boots instead of purchasing a full garment. DuPont does not manufacture or sell chemical resistant boots. However, we do offer some coveralls and encapsulated suits with attached socks. These socks can be worn as an extra layer of protection inside of chemical resistant boots.

Universal Pressure Test Kit
DuPont™ Universal Pressure Test Kit for Level A Suits. Compact, lightweight, and self-contained pressure test kit. Designed for periodic air pressure testing on Level A fully encapsulating suits. Suitable for a variety of applications that require chemical protective clothing like Tychem®.
Features & Product Details
Tychem® RESPONDER® CSM combines multiple film barriers laminated to both sides of a high-strength polypropylene substrate for high level protection against toxic and corrosive chemicals. It is effective for handling chemical warfare agents as well as military site cleanup and HazMat first response. Tychem® RESPONDER® CSM fabric provides at least 30 minutes of protection against 320 chemical challenges. Each suit undergoes rigorous inspection and each Level A suit, pressure testing. Each fabric lot is tested using live toxic agents plus one garment for each test fabric production run is also tested for seam barrier with live toxic agents. Desert tan color for low visibility applications.
- Encapsulated Level A garment design is our highest level of protection from liquid splash and vapor/gas exposures for both the wearer and respiratory equipment
- Double taped seams provide strong chemical resistance against heavy liquid splashes. A sewn seam is covered, both inside and outside of garment with compatible chemical-resistant material by heat-sealing.
- Standard-width, anti-fog, three-layer (PVC 40 mil / Teflon™ 5 mil / PVC 20 mil) faceshield
- Front entry design allows wearer to partially don garment (maintain standby position) without assistance
- Expanded back to accommodate self-contained air breathing apparatus (SCBA)
- Vapor tight zipper. Extra long to increase garment opening and aid donning and doffing
- Storm flap covers zipper which can be secured by the wearer with rugged hook and loop material to prevent intrusion at zipper
- Integrated socks composed of garment material
- Attached flaps are designed to cover boot tops to help reduce potential for liquid intrusion
- Two exhaust valves release higher pressure inside encapsulating garments while simultaneously helping to prevent inward leakage of external vapors or particles into the garment. One-way valves are positive pressure and open on demand. Valves include splash covers made of barrier material to help prevent liquid intrusion. Valves are located on left back of head and right lower back.
- Each suit has a unique serial number and is fully tested at time of manufacture including positive air pressure integrity testing per ASTM F1052.
- Pass-thrus are optional and can be installed upon request when ordering. Some suits are available with optional pass-thrus to accommodate the following SCBA manufacturers: Scott, Interspiro, MSA, Draeger, Survivair®. Please call Customer Service 1-800-931-3456 for additional information.
