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.
