==Safety==
People may be exposed to elemental silicon in the workplace by breathing it in, swallowing it, or having contact with the skin or eye. In the latter two cases, silicon poses a slight hazard as an irritant. It is hazardous if inhaled.<ref name="msds">{{cite web |url=http://www.sciencelab.com/msds.php?msdsId=9924921 |title=Material Safety Data Sheet: Silicon MSDS |author=Science Lab.com |website=sciencelab.com |access-date=11 March 2018 |archive-url=https://web.archive.org/web/20180323183044/http://www.sciencelab.com/msds.php?msdsId=9924921 |archive-date=23 March 2018 |url-status=dead }}</ref> The [[Occupational Safety and Health Administration]] (OSHA) has set the [[Permissible exposure limit|legal limit]] for silicon exposure in the workplace as 15&nbsp;mg/m<sup>3</sup> total exposure and 5&nbsp;mg/m<sup>3</sup> respiratory exposure over an eight-hour workday.
