Which of the following might be included in safety gear emphasized during Blue Card training?

Hard hats and gloves are essential components of safety gear emphasized during Blue Card training because they are specifically designed to protect workers from potential hazards typically encountered on construction sites or in hazardous work environments. Hard hats shield the head from injuries caused by falling objects, while gloves provide grip and protect the hands from cuts, abrasions, chemicals, and other dangers.

In the context of the other options, business attire, casual clothing, and fashion accessories do not offer the necessary protection against workplace hazards. Wearing appropriate safety gear, like hard hats and gloves, is crucial for ensuring the safety and well-being of employees, making this the correct choice in the context of safety training.
