Chemical Resistance Ratings 0 < 10 minute breakthrough time 1 ≥ 10 minute breakthrough time • The permeation breakthrough time is poor and the chemical has low volatility. Visit our updated, Permeation, degradation, and breakthrough: How they affect your PPE, All about the NIOSH Pocket Guide to Chemical Hazards, More Production with less cost is within reach – it’s all about the glove…, Superior Glove webinar: The No B.S. OR • The permeation breakthrough time is not recommended and the chemical has either high or low volatility. It is best to base glove material selection on the manufacturer’s chemical resistance guide.
A hazard assessment can be performed by an industrial hygienist or other safety professional familiar with the task.
GLOVE SELECTION GUIDE By closing this message or continuing to use our site, you agree to the use of cookies. When choosing your glove, look for the stated thickness on the manufacturer’s test data. The hazard assessment begins with knowing what chemicals or combination of chemicals the task or job requires. The ratings are a part of the ANSI/ISEA 105-2000 American National Standard for Hand Protection Selection Criteria. Selections must be based on the particular manufacturer’s test data. Even the best chemically resistant glove will break down after repeated chemical exposures. This rule makes it mandatory to match the right glove material with each application or task. View all Quick Tips Technical Resources at www.grainger.com/quicktips. The manufacturer runs permeation and degradation tests in accordance with standards established by the American Society for Testing and Materials (ASTM F739). Before each use, gloves must be inspected for signs of chemical degradation such as swelling, cracking, shrinking or discoloration of the material. ... Time 10 .
Attention should be focused on potential local skin effects, as well as potential absorption through the skin and resultant systemic effects. The decontamination procedures would probably cost more than replacing the gloves, so glove manufacturers do not recommend it.

I want to hear from you. Thinner, lighter gloves offer better touch sensitivity and flexibility while chemical resistance is sacrificed. Certified safety experts will review best practices for remaining compliant with fall protection, hazard communication, and lockout/tagout. A glove that is well suited for one application may not be right for another. - Kimberly-Clark* Blue Nitrile Exam Gloves - Kimberly-Clark* Forest Green Nitrile Exam Gloves - Kimberly-Clark* Purple Nitrile Exam Gloves - Kimberly-Clark* Spring Green Nitrile Exam Gloves - Kimberly-Clark* Sterling* Nitrile Exam Gloves Permeation Breakthrough Time (PB) Rating Minutes Excellent (E) 60-480 Good (G) 10-59 Poor (P) 1-9 The example given is .001, but is sometimes expressed as “E” or “P” for excellent or poor. WHEN BREAKTHROUGH OCCURS, THE GLOVE IS NO LONGER PROVIDING ADEQUATE PROTECTION. Typically expressed as a greater than symbol (>), the example shows the test was run for 480 minutes and then stopped.
Gloves also have a variety of finishes and linings. By visiting this website, certain cookies have already been set, which you may delete and block. When assessing the job, also take into account the length of glove needed.
The next step is to determine the chemicals’ toxic properties by reviewing the Material Safety Data Sheets (MSDS). Not Recommended, breakthrough times generally less than 1 hour. One of these standards (29 CFR 1910.138) specifically addresses the need for hand protection or chemical protective gloves: Learn how to avoid becoming another OSHA statistic. Textured finishes are applied to gloves to give a better grip. This includes assessing the job for chemical exposures, and then selecting the appropriate chemical protective glove based on material, thickness, length and other traits. Also during inspection, look for any signs of holes or punctures and remove the gloves from service if any are found. Some tasks may require only splash protection or include intermittent contact, while others may involve complete immersion or continual contact with the chemicals. This measurement is also limited to the “LDL” or Lower Detection Limit of the equipment used.
