Inhalation is the most common route of entry for workplace chemical hazards because workers breathe contaminated air continuously throughout their shift.

Question 4

What is the primary purpose of a Threshold Limit Value (TLV) as published by ACGIH?

Accepted Answer

To define concentrations below which nearly all workers can be repeatedly exposed without adverse health effects

Answer

ACGIH TLVs are occupational exposure guidelines representing conditions under which nearly all workers may be repeatedly exposed without adverse health effects.
