Screens or shields should be used in welding operations to protect:

Using screens or shields in welding operations is essential primarily to protect nearby workers. When welding, intense light, heat, and spatter are produced. The bright arc can cause eye damage, such as arc eye or flash burn, and the heat and sparks can pose burn risks or ignite flammable materials. Therefore, it's crucial to set up protective barriers to ensure a safe working environment for anyone in proximity to the welding process.

While the welder certainly needs personal protective equipment, the use of screens or shields goes beyond individual safety to encompass the well-being of coworkers who may not have the same level of protection. By focusing on safeguarding workers in the vicinity, the workplace can maintain a safer condition overall during welding activities.
