How should scraps on a work surface be discarded?

The correct approach for discarding scraps on a work surface is to use a brush or a scrap piece. This method is preferred because it minimizes the risk of injury and maintains a safer work environment. Using a brush allows for the careful sweeping of small pieces without the need for direct hand contact, which can prevent cuts and other injuries. A scrap piece can also serve to push or guide the scraps into a designated disposal area, avoiding the potential for sharp edges or splinters to cause harm.

Additionally, these techniques promote better housekeeping practices in the workspace. Maintaining a clean area helps to prevent accidents, such as slipping or tripping over debris, and ensures that the workspace remains organized for ongoing tasks.

Other methods, such as discarding scraps by hand or using a broom, may not be as effective or safe, and throwing debris in the air is certainly not an appropriate or responsible method of disposal.
