ProShield DuPont has engineered their ProShield® apparel to provide the perfect degree of protection against non-hazardous exposure in the workplace. Their limited-use garments are designed to optimize comfort and breathability without compromising on quality. ProShield® apparel offers affordable and practical barrier protection against non-hazardous liquids and particulates. When it comes to these light duty tasks, DuPont has you and your workers covered.

Tyvek DuPont’s Tyvek® protective garments protect millions of workers against low-concentration inorganic particles and chemicals, down to a single micron in size. Tyvek® apparel provides the ideal balance of comfort, durability and protection to keep workers protected against hazardous particulates and light liquid chemical splashes. The fabric itself is protective, without films or laminates that can deteriorate or abrade. The comfort-fit design allows for enhanced range of motion and durability, allowing workers to be comfortable and productive in any situation. Perfect for asbestos abatement, insulation installation, and similar labor-intensive tasks involving hazardous substances.

Tychem Countless workers worldwide rely on Tychem® protective garments to shield their bodies from chemical hazards. These products have improved on the threads and material to provide top-shelf protection you won’t find elsewhere. Tychem® apparel offers robust, yet lightweight protection against a broad range of chemical, biological and thermal (FR) hazards.

Occupational Safety and Health Administration (OSHA) Standards


29 CFR 1910.1030 "Bloodborne pathogens"
This standard shall specify the minimum responsibilities of an employer to provide PPE such as, but not limited to, gloves, gowns, laboratory coats, face shields or masks and eye protection, and mouthpieces, resuscitation bags, pocket masks, or other ventilation devices when an employee is potential exposed to bloodborne pathogens. Please note that there are 28 OSHA-approved occupational safety and health State Plans. State Plans are required to have standards and enforcement programs that are at least as effective as federal OSHA’s and may have different or more stringent standards related to PPE. More information about State Plans and their standards is available at: http://www.osha.gov/dcsp/osp/index.html

International Organization for Standardization (ISO)


ISO 6529:2013 "Protective clothing -- Protection against chemicals -- Determination of resistance of protective clothing materials to permeation by liquids and gases"
ISO 6529:2013 describes laboratory test methods to determine the resistance of materials used in protective clothing, including gloves and including footwear, when the footwear is an integral part of the clothing, to permeation by liquid or gaseous chemicals under the conditions of either continuous or intermittent contact. Method A is applicable to testing against liquid chemicals, either volatile or soluble in water, expected to be in continuous contact with the protective clothing material. Method B is applicable to testing against gaseous chemicals expected to be in continuous contact with the protective clothing material. Method C is applicable to testing against gaseous and liquid chemicals, either volatile or soluble in water, expected to be in intermittent contact with the protective clothing material. These test methods assess the permeation resistance of the protective clothing material under laboratory conditions in terms of breakthrough time, permeation rate and cumulative permeation. These test methods also enable qualitative observations to be made of the effects of the test chemical on the material under test. These test methods are only suitable for measuring permeation by liquids and gases. These test methods address only the performance of materials or certain materials' constructions (e.g. seams).

Frequently Asked Questions

What is the difference between single-use, limited-use and reusable chemical protective garments?
Single-use garments are intended for a one-time wear. Limited-use garments can be worn until they are damaged, altered or contaminated. Reusable garments can be worn multiple times as long as the suits have not become damaged during use (or if so, repaired), the suits have been completely decontaminated after use and the barrier performance of the fabric has not been compromised. Determining whether or not a reusable garment has been fully decontaminated and that the contaminates have not altered the strength or protection capabilities of the garment can be a difficult decision. DuPont chemical protective garments are limited-use garments. As long as they have not been damaged, altered or contaminated, they have sufficient durability to be worn multiple times.
What is the difference between penetration and permeation? How do I know which test method to use?
In terms of chemical protective clothing, penetration is the passage of a chemical through a pore or opening in the barrier material. Permeation is the absorption, diffusion and desorption of a chemical through the barrier material at the molecular level.
To help you understand the difference between these two mechanisms, consider this example. Have you ever opened an old bottle of soda to find out that it was flat? There aren't any holes in the bottle. The liquid is still inside. Why is the soda flat? It's flat because the carbon dioxide that gives soda its fizz has permeated through the walls of the bottle over time. If you opened a fresh bottle of soda and did not replace the cap, the carbon dioxide would just escape out of the top of the bottle. That would be penetration.
Penetration tests are well suited for determining particle barrier in fabrics like Tyvek® and ProShield®. Some factors that influence particle penetration include the size of the particle and the size of the pores/openings in the fabric structure. The more open a fabric structure is, the more likely a particle will be able to penetrate the fabric.
Permeation tests, by comparison, are better suited for testing hazardous liquids and vapors. It is the test method of choice for Tychem® fabrics. There are many critical factors that influence permeation: the challenge chemical (i.e. concentration, temperature, surface tension, the size of the molecules, functional groups, etc.), the make-up of the barrier material, the exposure time and several physical factors like ambient temperature and pressure, just to name a few. Because there are so many variables, DuPont has performed permeation tests on hundreds of chemicals against our Tychem® fabrics.
Does DuPont offer any garments that would be compliant with the OSHA Bloodborne Pathogens Regulation, (29 CFR 1910.1030)? What are ASTM F1670 and ASTM F1671? Does DuPont offer any garments that pass these tests?
Tyvek® and all Tychem® garments could be considered for use as protection against blood and bloodborne pathogens per OSHA 29 CFR 1910.1030. ASTM F1670 is a synthetic blood penetration test and ASTM F1671 is a viral penetration test. Tychem® 2000, Tychem® 4000, Tychem® 5000, Tychem® 6000 and Tychem® 6000 FR fabrics and taped seams have been tested and pass ASTM F1670 and F1671.
