Which of the following is NOT a safety consideration in additive manufacturing?

Operating equipment without protective gear is indeed the choice that does not align with the safety considerations in additive manufacturing. In any manufacturing setting, including additive manufacturing, safety gear is essential to protect workers from potential hazards. This can include respiratory protection, eye protection, and gloves, depending on the materials and processes used.

Proper ventilation for fumes is critical because many additive manufacturing materials, such as certain plastics, can emit hazardous fumes during the printing process. Ensuring that the workspace is adequately ventilated helps to mitigate risks associated with inhaling these fumes.

Handling hazardous materials is another significant safety consideration. Many of the raw materials used in additive manufacturing can be toxic or harmful if not handled correctly, requiring specific protocols and training for workers.

Safety in the working environment is a fundamental concern in all forms of manufacturing. This includes everything from ensuring that workspace is organized to understanding machine operation and emergency procedures.

In summary, while all the other options relate directly to crucial safety measures to ensure the health and well-being of workers, operating equipment without protective gear disregards fundamental safety practices and could lead to accidents or injuries.
