The name of the author is Garland. Years in the past we moved to Kansas. Interviewing is what she does in her day job but soon her husband and her will begin their personal business. Playing croquet is something I will never give up.<br><br>Feel free to surf to my site [http://www.Saintpeteryouthbasketball.org/ActivityFeed/MyProfile/tabid/60/userId/95760/Default.aspx www.Saintpeteryouthbasketball.org]
This page provides supplementary chemical data on [[tetrachloroethylene]]. <!-- replace with proper wikilink -->
 
== Material Safety Data Sheet == <!-- KEEP this header, it is linked to from the infobox on the main article page -->
 
The handling of this chemical may incur notable safety precautions. It is highly recommended that you seek the Material Safety Datasheet ([[Material safety data sheet|MSDS]]) for this chemical from a reliable source  such as [http://www2.siri.org/msds/index.php SIRI], and follow its directions. MSDS is available from [https://fscimage.fishersci.com/msds/22900.htm Fisher Scientific].
