Risk control can start with short-term interim measures while a long-term fix is developed, such as raising a bench temporarily or rotating workers off a low bench. To implement the most effective controls: communicate the reasons for change; involve workers; develop work procedures so controls and responsibilities are clear; train workers to apply the controls competently; let workers trial solutions before making them permanent; keep equipment maintained; and review after an initial test period because controls may need modification. Do not judge effectiveness until workers have had time to adjust, since new muscle groups or body parts may cause discomfort at first, and check frequently with workers and supervise to make sure controls are applied effectively.
