Question: 1 / 400

When using the clock concept for a right-handed operator, where is the static zone located?

12 or 2 o'clock

The static zone is located at either 12 or 2 o'clock when using the clock concept for a right-handed operator. This is because the clock concept is used to determine the most efficient and safe area of operation for the operator's dominant hand. The other options, 3 or 5 o'clock, 6 or 8 o'clock, and 9 or 11 o'clock, are incorrect because they are not considered within the static zone for a right-handed operator. Placing the dominant hand at these positions may result in awkward or inefficient movements and could potentially compromise safety. Therefore, the static zone is limited to 12 or 2 o'clock.
