Where will all pushbuttons be installed relative to their associated stop buttons?

• A. above or to the left
• B. below or to the right
• C. in front of
• D. behind

Answer: (A)

Placing pushbuttons above or to the left of their associated stop button creates a clear, predictable control layout that aids safe and quick operation. This arrangement makes the start control easy to identify at a glance, while the stop control remains in a consistent, easily reached location for immediate shutdown when needed. It also helps prevent mistaking one control for the other during high-pressure situations.

If the pushbutton were placed below or to the right, or positioned in front of or behind, it would be harder to distinguish quickly which control is which and could slow down a rapid shutdown or lead to accidental presses.
