On page 1454, Table 5 (under "Respirable dusts and fibers"), glass wool, rock wool, and slag wool fireproofing should not have appeared in the listing of Group 2B human carcinogens because they were downgraded to Group 3 in the latest monograph to address these substances (IARC 2002a); special purpose glass fibers such as E-glass and "475" glass fibers are not used in the "Reinforced plastic industry" but rather in "High-efficiency air filtration media and battery separator media" (IARC 2002a).
