What is the meaning of this hazard symbol?

這個危險符號的含義是什麼？

BlackTom AI · Accepted Answer

The question asks for the meaning of the hazard symbol shown in the image.
Option 1: Biohazard (生物危害). The biohazard symbol consists of three interlocking crescents forming a central circle, not the three-bladed circle we see. So this is incorrect for the pictured symbol.
Option 2: Ionization (電離危害). There is no standard hazard symbol labeled as 'ionization' with this design in common safety signage; ionizing radiation is typically represented by the radiation trefoil itself, but the option wording here doesn't match the conventional symbol or classification. This option is not the correct match for the image.
Option 3: Radiation (輻射危害). The symbol in the image is the classic radiation trefoil—three blades around a central point—inside a triangular warning sign. This symbol is widely recognized as indicating radiation hazards, including ionizing radiation, and is used to warn of radioactive materials, sources, or areas where radiation exposure is possible. This is the most appropriate interpretation of the image.
Option 4: Laser (激光危害). The laser hazard symbol usually shows a beam or a diode-like icon with lines indicating laser light, not the trefoil design. Therefore, this option does not describe the symbol shown.
Overall, the symbols in Options 2 and 4 differ in design from the image, and Option 1 corresponds to a different hazard class altogether. The sign depicted aligns with the radiation warning symbol used in contexts where exposure to ionizing radiation is a risk.
