Answer:
A heading, bright colors, and a numbered list.
Explanation:
The document's purpose is to briefly inform about workplace safety rules, it begins with a heading (the only one, thus, there is no subheadings): Workplace Safety Rules, and continues with a numbered list from 1 to 8 on the left side of the paper. On the right side, it only has a simple rhombus in yellow with a phrase on it in black, which is simple and not eye-catching. And it uses yellow and black through the document as the main colors, especially yellow which is a bright color.
