CAUTION:

The hazards that you list for your hazard scenario must be used independently of each other in the work environment. This tool does not evaluate chemical reactions or have the ability to recognize multiple chemicals as ingredients in a chemical mixture.
Do not use this form to list ingredients for a chemical mixture. Chemical mixtures behave differently than the individual constituents. Do not make the assumption that a fabric will provide protection if it shows barrier protection against the most hazardous ingredient. If one ingredient is able to permeate the fabric, it may pull other ingredients through the fabric as well.

SPECIAL WARNINGS

*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.

*CAUTION: This information is based upon technical data that DuPont believes to be reliable. It is subject to revision as additional knowledge and experience are gained. DuPont makes no guarantee of results and assumes no obligation or liability in connection with this information. It is the user's responsibility to determine the level of toxicity and the proper personal protective equipment needed. The information set forth herein reflects laboratory performance of fabrics, not complete garments, under controlled conditions. It is intended for informational use by persons having technical skill for evaluation under their specific end-use conditions, at their own discretion and risk. Anyone intending to use this information should first verify that the garment selected is suitable for the intended use. In many cases, seams and closures have shorter breakthrough times and higher permeation rates than the fabric. Please contact DuPont for specific data. If fabric becomes torn, abraded or punctured, or if seams or closures fail, or if attached gloves, visors, etc. are damaged, end user should discontinue use of garment to avoid potential exposure to chemical.

Important Note

 

The permeation data published have been generated for DuPont by independent accredited testing laboratories according to the test method applicable at that time (EN369, ASTM F739, EN 374-3, EN ISO 6529 (method A and B) or ASTM D6978)
The data is typically the average of three fabrics samples tested.
All chemicals have been tested at an assay of greater than 95 (w/w) % unless otherwise stated.
The tests were performed at room temperature and environmental pressure unless otherwise stated.
A different temperature may have significant influence on the breakthrough time.
Permeation typically increases with temperature.

Cumulative permeation data have been measured or have been calculated based on steady state permeation rate.
Cytostatic drugs testing has been performed at a test temperature of 27°C according to ASTM D6978 or ISO 6529 with the additional requirement of reporting a normalized breakthrough time at 0.01 µg/cm²/min.
Chemical warfare agents (Lewisite, Sarin, Soman, Mustard, Tabun and VX Nerve Agent) have been tested according to MIL-STD-282 at 22°C or according to FINABEL 0.7 at 37°C.
Permeation data for Tyvek® is applicable to white Tyvek® 500/ Tyvek® 600 only and is not applicable for other Tyvek® styles or colours.
Permeation data are usually measured for single chemicals. The permeation characteristics of mixtures can often deviate considerably from the behaviour of the individual chemicals.

 

Please use the permeation data provided as a part of the risk assessment to assist with the selection of a protective fabric, garment or accessory suitable for your application. Breakthrough time is not the same as safe wear time. Breakthrough times are indicative of the barrier performance, but results can vary between the test methods and laboratories. Breakthrough time alone is insufficient to determine how long a garment may be worn once the garment has been contaminated. Safe user wear time may be longer or shorter than the breakthrough time depending on the permeation behaviour of the substance, the toxicity of the substance, working conditions and the exposure conditions (e.g. temperature, pressure, concentration, physical state).

EXPOSURE SCENARIO

I have multiple hazards and need to answer these questions differently for each of my hazards.
On the screen where you enter your hazards, only put the hazards for which you can answer the exposure questions the same. This may mean that you have to work through multiple hazards scenarios.

Intensity

Mist - An incidental liquid exposure; a by-product of a spray

Spray - The liquid is coming at you directly (i.e. you are in the path of the spray). There is not sufficient pressure for the intensity to be considered a jet.

Jet - The liquid is under pressure or is of high volume

CAUTION - The wearer of the chemical garment should move out of the way of a jet exposure as quickly as possible. Garment protection information provided is based on limited initial exposure to a jet of the liquid chemical, not to continuous contact for an extended period of time.

Direction

A few notes about Localized Protection

  • By selecting one of the localized exposure options, SafeSPEC™ 2.0 will show partial body garments (e.g. lab coats, sleeve covers, shoe/boot covers, hoods, etc.) as possible results. This may happen even though a full body garment (e.g. coverall) may also be suitable for your hazard scenario.
  • Partial body garments are not available in every fabric.

Notice - Vapor-producing Liquids

One or more of your liquid hazards has a boiling point between 60-90° F (16-32° C) and may produce vapors in your working environment. Please read this notice and select the appropriate physical state for your hazards.

If the temperature of your working environment is close to or above the boiling point of your hazard, you may have vapor hazards, in addition to liquid hazards, in your working environment. If your hazard produces vapors that are skin contact hazards, select "Liquid and Vapor" as the Physical State Anticipated. This selection will lead you to a Level A suit. Only Level A suits provide skin vapor protection.

If the concentration of the vapor can be monitored in the working environment and can be proven to be lower than the permissible exposure level (PEL) and/or recommended exposure level (REL) for skin contact, or if the vapor is known to be non-hazardous via skin contact, select "Liquid Only" as the Physical State Anticipated.

If you have questions or concerns, please Contact Us for assistance.

Flammability classification based on the USA Consumer Products Safety Commission (CPSC) textile clothing standard. 16CFR1610 tests are used to determine if materials used in apparel have a high level of flammability. Class 1 = normal flammability, Class 2 = intermediate flammability, and Class 3 = high flammability.

NOTE: A Class 1 16CFR1610 rating does not indicate that the material is flame resistant

Need Help?

  • If you see your hazard 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 hazard listed,check the spelling and try again. You may also want to try the CAS number (located on the Material Safety Data Sheet (MSDS)). You may be searching by a synonym name that is not recognized in our database
  • There is the possibility that we do not have permeation data for the requested chemical.

NOTE:

Fabric permeation data is used as the basis for garment recommendations for hazardous liquids (either spray or jet exposures) and hazardous vapors. Unless otherwise noted, permeation testing was conducted at room temperature, approximately 20-27° C (68-81° F). An increase in temperatures in your work environment, either ambient or of the hazard, may reduce the barrier performance of the fabric.

There are additional hazards that are not considered in this selector tool including, but not limited to: asphyxiation, extreme heat or cold environments or hazards, physical hazards (such as cut, puncture and abrasion), slipping, falling and visibility.

CAUTION:

The wearer of the chemical garment should move out of the way of a jet exposure as quickly as possible. Garment protection information provided is based on limited initial exposure to a jet of the liquid chemical, not to continuous contact for an extended period of time.DuPont assumes no responsibility or liability for suit selection based on incomplete, inaccurate or misleading information and which does not consider all hazards.

I HAVE REVIEWED THE INPUT INFORMATION AND IT IS CORRECT. I UNDERSTAND THAT INACCURATE, INCOMPLETE OR MISLEADING INFORMATION OR INFORMATION WHICH DOES NOT CONSIDER ALL HAZARDS MAY RESULT IN AN INCORRECT SUIT RECOMMENDATION. I UNDERSTAND THERE MAY BE ADDITIONAL HAZARDS PRESENT FOR WHICH THIS SELECTION MAY NOT BE APPROPRIATE.
