Why use the hexagonal shape with the word “Danger” for the warning sign? Where does it come from?
A24. The stop sign with an irradiated human silhouette inside is a Workplace Hazardous Materials Information System (WHMIS) symbol and corresponds to a sign already used under the REDA to indicate that there is an immediate acute danger. In the case of this device, the danger is severe eye and skin burns or severe photoreactions from drugs or other products present on skin.
