Which of the following should be worn at all times in a metalworking environment?

In a metalworking environment, it is essential to wear closed-toe shoes for several safety reasons. These types of shoes provide necessary protection for the feet against heavy objects that may fall or get dropped, as well as shielding against sharp metal edges and discarded tools that could cause injury. Closed-toe shoes also help prevent slips and falls by providing better traction on potentially slippery surfaces commonly found in workshops and manufacturing settings.

Additionally, wearing proper footwear is part of maintaining overall safety standards in the workplace, contributing to a culture of safety and awareness while performing metalworking tasks. Other options present risks that could lead to serious injuries; for example, short sleeves might expose arms to cuts or burns, flip-flops do not provide adequate protection or support while moving around in an industrial setting, and loose clothing can become caught in machinery.
