2. Spring, 2001 2 HAZWOPER Selection of Protective Gloves

3. Spring, 2001 3 HAZWOPER Important points to consider: All chemicals will permeate protective barriers. No single protective material will be an effective barrier against all chemicals. Gloves and other PPEs may look similar, so care must be taken in choosing. A chemical that has been absorbed by a protective glove material will continue to permeate!

4. Spring, 2001 4 HAZWOPER Glove permeation data likely is based on room-temp conditions. Higher temps may likely increase permeation rates! Glove protection information based on generic materials. Manufacturers should be consulted. Increasing thickness normally will increase the time to breakthrough, but benefit may be offset by decrease in flexibility and tactility. If glove protection is critical to health, material should be tested against chemicals to be used!

5. Spring, 2001 5 HAZWOPER In the OSHA Standard for Air Contaminants (29 CFR 1910 Subpart Z), in Table Z-1-A (Limits for Air Contaminants), there is a column for Skin Designation. The standard states:

6. Spring, 2001 6 HAZWOPER �To prevent or reduce skin absorption, an employee�s skin exposure to substances listed in Table Z-1-A with an �X� in one or both of the Skin Designation columns following the substance name shall be prevented or reduced to the extent necessary in the circumstances through the use of gloves, coveralls, goggles, or other appropriate personal protective equipment, engineering controls or work practices.� A small subset of these chemicals include Acrylamide Isopropyl alcohol Benzene Methyl alcohol n-butyl alcohol Phenol Carbon disulfide Toluene Merck concerns?
