Talk:Permissible exposure limit

Untitled

Someone has proposed merging Occupational exposure limit with Permissible exposure limit I strongly oppose such a move. Occupational exposure limit is a very general term. Permissible Exposure Limit is a specific legal limit applicable in the United States in those circumstances where Federal OSHA has jurisdiction. These will become tow very different articles.

When are different units used :

Intro says "For chemicals, the chemical regulation is usually expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/m³)." (with no reference) - Are these for ingested chemicals, or those that contact the skin ? Is the mg/m³ usually used for contamination of breathed air - or of any gases in general ? - Rod57 (talk) 16:21, 19 February 2021 (UTC)

What is total exposure

[[1]] talks about total exposure but it's not defined here. - Rod57 (talk) 16:25, 19 February 2021 (UTC)

What's all the noise about?

Permissible_exposure_limit appears in the USA to apply to noise and chemicals. But this page seems to have eliminated any useful references to the various USA guidance documents on chemicals, statutory and non-governmental. It also fails to refer to the regulatory situation in other countries whose terminology is slightly different but covering the same topic. And how has Nixon slipped his corrupt face into this entry? Has someone hacked the page? There needs to a disagregation page to gather the various systems for this topic, MAK (Germany) WEL (UK), PEL (USA) ... to enable users to navigate through the international maze of H&S regulations.
