Frequently Asked Questions

TD127S WB option CM

DuPont™ Tyvek® 400 D

In what ways can I manage or prevent heat stress? Chemical protective clothing can interfere with the natural regulation of body temperature. This can lead to a rise in core body temperature and heat stress. Implementing a conservative work/rest schedule or using a cooling system may be effective in reducing heat stress. (Note: Do not wear cooling vests in potentially flammable or explosive environments.) .)

Be aware of the symptoms and treatment of heat stress. If you or your co-workers have symptoms of heat stress such as nausea, dizziness, high heart rates, or excessive heat build-up, leave the work area immediately and remove the ensemble as quickly as possible after decontamination and seek professional care.

The maximum length of time the chemical protective clothing can be worn depends on variables such as the air supply, ambient conditions, climate inside the ensemble, physical and psychological conditions of the wearer, work rate and work load. The TLV® pocket guide from the American Conference of Governmental Industrial Hygienists (ACGIH, Cincinnati) provides corrected heat stress limits for some garments. Similar information is available on the federal OSHA web site (www.OSHA.gov). The WBGT correction factor for chemical protective garments is at least 10°C or higher for chemical garments made of impervious films (such as Tychem® garments) and covering the entire body (hooded coverall or encapsulating designs). For Tyvek® coveralls, the WBGT correction factor is 2°C with a hood and 1°C without a hood. What determines if the garment is contaminated ? The decision on whether or not a garment has been contaminated is made by local managers responsible for PPE based on an analysis of the incident in which the garment was used. This analysis may include exposure time, chemicals involved, level of exposure, proximity to the actual release, tasks performed and environmental monitoring in the area in which the garment was worn. Garments that are damaged, altered or show signs of contamination, such as discoloration, odor, stiffening or cracks, should not be used. Are TYVEK® 400D garments anti-static or static dissipative ? The fabrics used to make TYVEK® 400D garments are treated with a topical antistatic agent to help minimize static build up and reduce nuisance garment cling.

In situations where static dissipation level is a critical performance property, end-users should evaluate the performance of their entire ensemble as worn including outer garments, inner garments, footwear and other PPE. In order for any garment system to be static dissipative, it must be able to drain a charge buildup through proper grounding devices, such as, but not limited to, workstation grounding clips or static-dissipative floors.

Under certain conditions, such as cold and dry weather, it is possible that garments might build and discharge static electricity. Discharges are not normally dangerous except in situations where the generation of an electrical spark could ignite a flammable atmosphere or startle the wearer. When operating around flammable chemicals, take steps to eliminate potential static discharges. In these situations, suggested steps include, but not limited to, water spray, the use of an overcover, raising humidity level of the work area, use of a commercial, anti-static application coating, grounding straps on equipment and personnel, inherently static-dissipating under- and over-garments, and testing of the worker's static dissipation before entry into the classified area.

However, in the case of explosive or flammable atmospheres, even if steps are taken to manage static formation and dissipate static charge, the risk of severe injury remains if an uncontrolled or accidental ignition occurs. Do not wear TYVEK® 400D chemical protective garments in potentially flammable or explosive atmospheres. Do not knowingly enter an environment in which the concentration of flammable gas is within flammable or explosive limits while wearing a TYVEK® 400D garment. If you determine that you are in a potentially flammable or explosive environment, retreat immediately. Are Tyvek® garments low linting? Tyvek® fabric is low-linting by nature of its continuously strong, high-density polyethylene fibers. DuPont cannot guarantee the absence of particles on these garments as threads and zippers can be the most significant source of contamination. For end users with concerns about contamination or any other contaminants, the best practice is to audit in-bound materials, including garments, for those contaminants. End users with highly specialized requirements may consider Tyvek® IsoClean® garments for controlled environments designated as Clean-Processed (0C option): These garments are specially processed to minimize particle shedding and individually packaged in an ISO Class 4 cleanroom. Is it possible to wash and re-use TYVEK® 400D garments? DuPont does not recommend washing TYVEK® 400D garments for re-use. These garments are designed for limited-use. They can be worn until damaged, altered or contaminated. Are TYVEK® 400D garments flame resistant or flame retardant (FR) ? No, TYVEK® 400D garments are not flame resistant or flame retardant and should not be used around heat, flame, sparks or potentially flammable or explosive environments. TYVEK® 400D garments will ignite and continue to burn and melt.

In addition, TYVEK® 400D garments should not be worn under or over a garment made of Nomex® or any other flame resistant fabric, if the potential for fire or electric arc exists. How should TYVEK® 400D garments be stored? Store TYVEK® 400D garments in a cool, dark, dry location free of dirt and insects. Sunlight, ozone, high temperatures (>120° F ; 49° C), vehicle exhaust fumes, compression under heavy weights and sharp edges or projections are some conditions known to degrade the materials in these garments.

Store TYVEK® 400D garments in boxes, in bags or on hangers. Never step on protective garments. Never place or store heavy objects on top of protective garments. In what ways can I dispose of TYVEK® 400D garments ? If not contaminated, TYVEK® 400D garments may be landfilled or incinerated in accordance with local regulations. Uncontaminated chemical protective garments may be incinerated in a facility that is capable of handling mixtures containing plastics. Likewise, an uncontaminated chemical protective garment may be buried in a facility that accepts plastic materials. TYVEK® 400D garments may contain several different materials; they are not suitable for recycling.

Contaminated garments that cannot be handled safely without protective equipment must be disposed of with other hazardous wastes, either through incineration or landfill per local regulations.

Before discarding, cut off a sleeve or a leg so the garments cannot be worn again as protective clothing. Do TYVEK® 400D products contain silicone? All DuPont Personal Protection products are manufactured under specifications that do not contain silicone, with some exceptions. Tyvek® friction-coated shoe covers or Tyvek® garments with friction-coated shoe covers might contain silicone. This includes Tyvek® styles TY122, TY121, FC450 and FC454. Additionally, Tychem® 6000 AL styles TF630 and TF640T contain a silicone valve diaphragm. End users who are consuming these styles and who have concerns about silicone contamination should conduct their own testing to ensure they are suitable for their application(s). Do TYVEK® 400D garments meet ANSI/ISEA 101 sizing standards? Yes. DuPont™ TYVEK® 400D coveralls either meet or exceed ANSI/ISEA 101 sizing standards. For specific sizing dimensions on a particular DuPont garment, please view the Product Details tab for that garment. Where can I find a SDS (Safety Data Sheet) for TYVEK® 400D garments? Safety Data Sheets (SDS) are written in accordance with applicable federal regulations, 29 CFR 1910.1200, to communicate health and safety data on usage and handling of hazardous chemicals. Under this regulation, DuPont™ Tyvek®, ProShield®, and Tychem® materials and garments are defined as articles, not chemicals, and the SDS and labeling requirements in that standard do not apply. Do TYVEK® 400D products contain latex? As of January 2023, all DuPont Personal Protection products are manufactured under specifications that exclude components containing natural rubber latex. Tyvek® 500, Tyvek® 600 and Tyvek® 800 styles made before January 2023 contain natural rubber latex, which may cause allergic reactions in some sensitized individuals. Anyone who begins to exhibit an allergic response during the use of DuPont products should immediately cease using these products and should report it to DuPont at +1 (888) 439-2988 so that an investigation can be initiated. What is the shelf life of TYVEK® 400D garments? There is no established shelf life for TYVEK® 400D garments. Can TYVEK® 400D garments be worn in cleanroom applications? TYVEK® 400D garments have not been designed for controlled environment applications. DuPont offers a full line of garments that have been specially manufactured, processed and packaged for use in controlled environment applications. Please see our complete line of controlled environment products at www.safespeccleanroom.dupont.com.

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.

SPECIAL WARNINGS

• *Intended for use in applications with frontal exposures as only the body front, leg front, arms and hood are made with DuPont™ Tyvek® fabric. Portion not comprised of Tyvek® fabric is more breathable and porous.
• *Serged and bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present.
• *Liquid barrier performance varies based on the amount of liquid that may get on the garment, the length of time the liquid is on the garment, applied pressure and certain physical properties of the liquid. Tyvek®400, Tyvek® 400 D, ProShield®, ProShield® 10, ProShield® 60, Tyvek® 400 FC, and ProShield® 70 garments are not appropriate if during use they are getting wet (liquid is dripping or running, or it is wet to the touch) or if spotting is observed on skin or garments worn under the protective garment. Tyvek® 500 and Tyvek® 600 offer improved liquid barrier, but may not be appropriate if spotting is observed on the skin or garments worn under the protective garment. In applications where a higher liquid barrier is needed, consider Tychem® 2000 and Tychem® 4000 garments with taped seams.
