请英语高手帮忙看看这几句英文怎么理解

1、Are documents and data reviewed and approved by authorized personnel, prior to issue?
2、Is there a master list of documents that are controlled and updated as needed?
3、Are all pertinent documents available to operators where the function is being performed?

这是一个客户要求我司填写的自评表内容，我英语太差了，呵呵，希望得到各位朋友的帮助！谢谢！
