1. Caution science used, unless otherwise authorized by the
commission, shall be of a trefoil design using the colors: -
correct answer - Magenta on a yellow background, purple on a
yellow background, or black on a yellow background.
2. What are the 3 classifications of exposure devices? - correct
answer - P-portable; M-mobile; F-fixed
3. Expose your devices are classified by categories I and II for the
ANSI standard N432. What are these categories? - correct
answer - Category I: Exposes the source through a shutter
