When bending EMT, on what type of surface should you work?

When bending Electrical Metallic Tubing (EMT), it is essential to work on hard flat surfaces. This choice is correct because a stable and level surface provides the necessary support and consistency needed to accurately and safely create bends in the tubing. Bending EMT requires precision to ensure that the angles are correct and that the tubing remains straight; a hard flat surface minimizes the risk of the tubing buckling or becoming distorted during the bending process.

Working on soft grass or uneven ground can lead to an unstable bending process, where the EMT could warp or bend improperly due to the lack of proper support. Similarly, curved surfaces would not provide the necessary rigidity and flat foundation that is critical for accurate bends. By working on a hard flat surface, you ensure that the bending process is efficient, controlled, and yields the best results for your electrical installations.
