Go to online PPE training.
The online PPE training pages were designed for Netscape, using a monitor resolution/size of 800 x 600, 16-bit (Hi) color, and browser set to use document-specified fonts and colors (or fonts set to something roughly equivalent to Times New Roman 12 pt). It will be possible but less convenient or "attractive" to undertake the training pages with a screen set to 640 x 480, less color, and/or other browser/settings. There will be more scrolling vertically and horizontally to see everything.
If you are a supervisor, please instruct all of your staff members (postdocs, undergrads, grad staff, technicians, everybody who needs it) to complete the appropriate PPE training.
