Their TLV publications can be accessed through with(predicate) purchase since their publications have copyrights. ACGIH-TLVs do not have a legal force in ground forces they are only recommendations/ guides and not regulatory limits due to individual susceptibility, hence ACGIH is not a standard setting body. Regulatory bodies view ACGIHs guidelines as an expression of scientific opinion. ACGIH has several committees set up that decides which philia is to be selected for study and votes once a year on action terms. Each substance / element is selected based upon its availability, relevance and scientific data.

OSHA requires that when workplace exposures slip away 100% of the PEL i.e. exposure exceed 90dBA, feasible engineering or administrative controls must be deployed to reduce noise levels. Engineering control includes redesigning space and operations to reduce noise at source, transmittal path or at receivers end. Administrative c ontrols include scheduling and controlling the level of exposure
