===Regulation, exposure limits===
In the US, fine [[mineral fiber]] emissions have been regulated by the [[EPA]], but [[respirable suspended particle|respirable fibers]] (“particulates not otherwise regulated”) are regulated by [[Occupational Safety and Health Administration]] (OSHA); OSHA has set the legal limit ([[permissible exposure limit]]) for fiberglass exposure in the workplace as 15&nbsp;mg/m<sup>3</sup> total and 5&nbsp;mg/m<sup>3</sup> in respiratory exposure over an 8-hour workday. The [[National Institute for Occupational Safety and Health]] (NIOSH) has set a [[recommended exposure limit]] (REL) of 3 fibers/cm<sup>3</sup> (less than 3.5 micrometers in diameter and greater than 10 micrometers in length) as a time-weighted average over an 8-hour workday, and a 5&nbsp;mg/m<sup>3</sup> total limit.<ref>{{Cite web|title = CDC – NIOSH Pocket Guide to Chemical Hazards – Fibrous glass dust|url = https://www.cdc.gov/niosh/npg/npgd0288.html|website = www.cdc.gov|access-date = 2015-11-03}}</ref>

As of 2001, the Hazardous Substances Ordinance in Germany dictates a maximum occupational exposure limit of 86&nbsp;mg/m<sup>3</sup>. In certain concentrations, a potentially explosive mixture may occur. Further manufacture of GRP components (grinding, cutting, sawing) creates fine dust and chips containing glass filaments, as well as tacky dust,{{Definition needed|What is tacky dust?|date=October 2022}} in quantities high enough to affect health and the functionality of machines and equipment. The installation of effective extraction and filtration equipment is required to ensure safety and efficiency.<ref name=Türschmann/>
