Chemical protective clothing such as that <br /> made of of E.I. DuPont Tychem®, products or equivalent is recommended based on degree of exposure. <br /> Note: The resistance of specific material may vary from product to product as well as with degree of <br /> exposure. Consult manufacturer specifications for further information. <br /> RESPIRATORY PROTECTION <br /> A NIOSH-approved air-purifying respirator with organic vapor cartridges or canister may be permissible <br /> under certain circumstances where airborne concentrations are or may be expected to exceed exposure <br /> limits or for odor or irritation. Protection provided by air-purifying respirators is limited. Refer to OSHA 29 <br /> CFR 1910.134, NIOSH Respirator Decision Logic, and the manufacturer for additional guidance on <br /> respiratory protection selection and limitations. <br /> Use a positive pressure, air-supplied respirator if there is a potential for uncontrolled release, exposure <br /> levels are not known, in oxygen-deficient atmospheres, or any other circumstance where an air-purifying <br /> respirator may not provide adequate protection. <br /> 9.
