185. Two-hand control device: A two-hand control device may be used as a means of protection when its design and installation(1) allow to prevent accidental or unintentional operation;
(2) require the operator to use both hands within 500 milliseconds to initiate the cycle of the machine or its system;
(3) require the operator to release both hands from each of the control actuators of the control device and reactivate it with both hands to initiate a machine or its system’s cycle;
(4) lead to a stop of the machine or its system as soon as the operator removes one hand from one of the control actuators of the control device during the cycle phase presenting a risk for worker health and safety;
(5) give the operator a clear view and complete control over the danger zone covered by the protection;
(6) allow the operator to activate the control actuators on the control device at a safe distance from the danger zone.
In addition, where a two-hand control device is used as a means of protection for more than one operator, a device must be provided for each operator. The devices must be designed to ensure that the machine can only be started when all the controls on the two-hand devices are actuated and maintained in that position by all the operators.
