Can these Tychem® 2000 garments be worn in cleanroom applications?
Tychem® 2000 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.
Are Tychem® 2000 garments anti-static or static dissipative?
The substrate used to make Tychem® 2000 garments is 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 wearTychem® 2000 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 Tychem® 2000 garment. If you determine that you are in a potentially flammable or explosive environment, retreat immediately.
How should Tychem® 2000 garments be stored?
Store Tychem® 2000 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 Tychem® 2000 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 Tychem® 2000 garments ?
If not contaminated, Tychem® 2000 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. Tychem® 2000 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.
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 like the DuPont™ Cool-Guard® vest 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.
Do Tychem® 2000 garments meet ANSI/ISEA 101 sizing standards?
Yes. DuPont Tychem® 2000 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.
Is it possible to wash and re-use Tychem® 2000 garments?
DuPont does not recommend washing contaminated Tychem® 2000 garments for re-use. These garments are designed for limited-use. They can be worn until damaged, altered or contaminated. However, if the garments have not been contaminated, they can be cleaned for hygienic purposes and re-used. Please refer to the section on Decontamination and Cleaning in the Tychem® User Manual - Encapsulated for more information.
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.
What are the donning and doffing instructions for Tychem® 2000 coveralls?
Please refer to the Section on Donning and Doffing Non-Encapsulating Garments in the Tychem® User Manual - Non-Encapsulated.
Are Tychem® 2000 garments flame resistant or flame retardant (FR)?
Other than Tychem® 6000 FR, Tychem® chemical protective garments will ignite and continue to burn.
Wearing garments made of Nomex® or any other flame-resistant fabric under Tychem® garments, other than Tychem® 6000 FR, will not reduce burn injury during a fire or electric arc exposure. Other than Tychem® 6000 FR, Tychem® garments will burn and possibly melt when exposed to a fire or electric arc flash; this may increase burn injuries even when worn over garments made of Nomex® or any other flame-resistant fabric.
And because Tychem® garments melt, except for Tychem® 6000 FR do not wear Tychem® garments under a garment made of Nomex® or any other flame resistant fabric if the potential for fire or electric arc flash exists.
Do not knowingly enter an environment in which the concentration of flammable gas is within flammable or explosive limits when wearing a Tychem® garment, including when wearing a Tychem® 6000 FR garment. Retreat immediately if you encounter such an environment while wearing any Tychem® garment, including Tychem® 6000 FR.
No Tychem® garment, including Tychem® 6000 FR,is intended for fire fighting activities, nor for protection from hot liquids, steam, molten metals, welding, or thermal radiation. Tychem® 6000 FR garments are designed and tested to help reduce injury during escape from a fire and to provide some protection from electric arcs.
What is the shelf life of Tychem® 2000 garments?
Tychem® garments may be used for 5 years from the date of manufacture as long as all of the following conditions are met:
- The garment has been stored properly (view storage conditions)
- The garment has not been damaged, altered or contaminated
- The garment passes a full visual inspection (view garment inspection instructions)
Where can I find a SDS (Safety Data Sheet) for Tychem® 2000 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® 400, Tyvek® 400 D, Tyvek® 500, Tyvek® 600, Tyvek® 400 FC, ProShield®, ProShield® 70 , ProShield® 50 , ProShield® 10, ProShield® 60, ProShield® 6 SFR and Tychem®, materials and garments are defined as articles, not chemicals, and the SDS and labeling requirements in that standard do not apply.
Are Tychem® 2000 garments latex free?
With the exception of models TF 611T, QS 127T and QC 125T with option code DC, as of January 1, 2006, all DuPont™ Tychem® garments that are manufactured by DuPont and sold in the United States are manufactured under specifications that exclude components containing natural rubber latex or are manufactured in such a way that any natural rubber latex will not come in contact with the wearer during normal handling and use.
What is the ambient working temperature range for Tychem® 2000 garments?
Tychem® garments can be worn in ambient temperatures of -13°F (-25°C) to 165°F (74°C).
In colder environments, Tychem® garments can become stiff. If cold enough, the fabric may even become brittle. Please be aware that the heat stress of the wearer becomes a greater concern in higher ambient temperatures. At higher temperatures, chemical hazards can become more aggressive. Breakthrough times and permeation rates may change at higher temperatures. The published permeation data per ASTM F739 is performed at ambient temperatures (approximately 72-81° F ; 22-27° C).
Caution: Tychem® fabrics offer little or no thermal insulation to protect the wearer's skin from prolonged exposure to hot or cold.
Tychem® is an innovative fabric range comprising multiple barrier layers that help provide protection from chemical and biological hazards. Laminated to Tyvek® for strength, it offers a robust solution with a high level of chemical barrier at uncharacteristically low weight.
Comfort & Weartime Are TYCHEM® styles breathable? TYCHEM® styles are not air - or water vapour permeable due to their material structure. The work place risk assessment should evaluate how long a wearer can work in a non-breathable suit.
DuPont™ Tychem® TK. Gas-tight suit with attached boots. Attached double gloves (removable). For use with SCBA. Wide panoramic visor.
DuPont™ Tychem® 4000 delivers effective protection against a range of chemical environments. Tychem® 4000, utilizes Saranex™ 23-P film laminated to Tyvek® fabric to provide a rugged and durable fabric that resists abrasion. Tychem® 4000 fabric provides at least 30 minutes of protection against >124 chemical challenges.
It is important to know that Tyvek can only handle a light liquid splash, so it is typically used for protecting against dry substances such as dust. If you need protection against hazardous liquids, a DuPont Tychem Suit is an excellent choice. It was designed especially for biological and chemical protection.
All DuPont™ Tychem® chemical protective garments may contain materials, including gloves and closures for which there is no specific storage life data available. It is suggested that garments be labeled and retired to “Training Use Only” after 5 years after receipt by the purchaser.
Put on a cooling vest under your suit to lower your body temperature. Get a disposable cooling vest if you don't use your Tyvek suit often. If you regularly wear your suit, invest in a reusable vest that has pockets for ice packs. Wear the cooling vest under your Tyvek suit to help you stay cool all day.
Tyvek® industrial protective garments are single-use products and not intended for reuse. DuPont does not recommend washing or disinfecting Tyvek® garments for reuse.
Protective suits keep radioactive isotopes out of your body, but cannot shield you against the ionizing radiation.
Level A Suits | The highest level of protection and require SCBA equipment. This suit protects against chemicals and airborne particles. Level A is designed to be used to safeguard one's eyes, lungs, and skin from liquids and gasses. Level B Suits | Protect against liquid splashes and require SCBA equipment.
Tychem SL Coveralls provide a higher level of chemical protection than Tychem QC coveralls. These coveralls effectively protect you against a broad range of chemicals.
Tyvek HomeWrap, Tyvek DrainWrap and Tyvek StuccoWrap should be covered within 120 days (4 months). Tyvek CommercialWrap should be covered within 270 days (9 months).
While Tyvek® is non-toxic and generally harmless, builders should be aware of one lurking danger: static electricity. When Tyvek® is handled, it can generate a static charge unless it is treated with anti-static agents, which are water-soluble and not applied on all Tyvek® products sold.
No problem! Tyvek® is tear, puncture, water, UV and chemical resistant. When wet, paper absorbs humidity and falls apart. Tyvek® repels water, keeping your message perfectly intact.
Therefore, use is usually limited to short durations of up to 2 hours, depending on the difficulty of the work. Level A (United States) suits, for example, are limited by their air supply to around 15–20 minutes of very strenuous work (such as a firefighting rescue in a building).
DuPont suggests that Tyvek® IsoClean® coveralls be used within 5 years, provided they are properly stored and pass a full visual inspection. High temperature, oxidizing gases, wet, cold, ultraviolet and ionizing radiation can significantly impact the long-term life of coveralls made of Tyvek® fabric.
The Shelf Life of Chemical Suits
The shelf life of a chemical suit should be quoted within the product's packaging or instructional material. Most manufacturers will suggest a shelf life of 10 years for chemical suits that are unopened and stored properly.
The melting point of Tyvek® is 135°C and the ignition point of high density polyethylene is approximately 400°C.
Some units try to mitigate the heat by using semi-permeable suits such as the Blauer suit (From personal experience, a HAZMAT suit is hot! No matter what!). The risk of heat injuries is so great within the suits that workers are required to have their vital signs checked before and after their work cycles.
Tyvek® for PPE delivers comfortable and durable protective garments that protect against a wide range of chemical threats and hazards. From the cleanroom to a hazardous cleanup, Tyvek. Tyvek® provides inherent barrier protection against lead, asbestos, mold and more.
Tyvek coveralls are not meant to be washed and they may rip if you try to wash them. You can use the coveralls more than one time as long as you do not rip them and they are not covered in hazardous materials.
Protective suits may look the same, but only from a distance. DuPont's unique Tyvek® material goes beyond superficial similarities to offer an ideal balance of protection, durability and comfort on the market today.
It is completely waterproof, and keeps all of its strength when wet. It is easy to sterilize, and once made into packaging is able to maintain sterile for many years. For this reason, Tyvek material has been used in a vast variety of contexts over the past 60 years.
PVC acid chemical suit is made of fire-retardant . 42mm 3 ply Green PVC/Nylon/PVC combined material. Acid resistant level C suit is made to be comfortable and flexible yet provides superior snag resistance and protection from harmful industrial substances such as acids, alkalis, salts, and oils.
Aging studies indicate that Tyvek® IsoClean® garments have a sterility expiration date of at least 5 years when stored in original packaging under proper storage conditions.
A Hazmat suit, short for hazardous material suit, is a whole body garment designed to protect the wearer against dangerous materials or substances.
