What is the threshold limit value (TLV) for a product of PHTHALIC ANHYDRIDE?

A 1 ppm
B 2 ppm
C 3 ppm
D 4 ppm
AI Explanation

The correct answer is A) 1 ppm. The threshold limit value (TLV) for phthalic anhydride is 1 ppm, as established by the American Conference of Governmental Industrial Hygienists (ACGIH). This TLV represents the maximum airborne concentration of a substance to which most workers can be exposed without adverse health effects. The other answer choices are incorrect as they do not match the established TLV for phthalic anhydride.
