Can I Wipe My SSD from within the Drive Itself?

I have a 240 GB ssd that contains my entire system (distro and kernel). I want to wipe it and start fresh following these instructions: http://ift.tt/1xYVSiK

Will doing so from within the system itself create any problems? I plan to reinstall a new distro from a bootable USB afterwards. Also I don't intend to back up the drive as there is nothing on it I need.
