Which type of press specifically requires point of operation safeguarding?

Full-revolution presses specifically require point of operation safeguarding due to their operational characteristics. These presses complete a full cycle during each stroke, meaning that the moving parts—including the ram—spend a considerable amount of time in the danger zone where operators could be exposed to hazards. The nature of the mechanisms in full-revolution presses leads to the potential for serious injuries if body parts come in contact with the moving components during operation. Therefore, safeguarding must be employed at the point of operation to protect workers from potential crushing or shear injuries.

In contrast, the other types of presses each have different mechanisms and operational characteristics that may not pose the same level of risk in the point of operation. For example, quarter-revolution presses involve a mechanism that allows for a safer working condition during certain phases of the cycle, while continuous feed presses generally operate with a different method of feeding materials that involves less direct exposure for operators. Modification presses may refer to those that have been altered, and their safety requirements would depend on the specific modifications made rather than adhering to a standard.
