RADIO COMMUNICATION REQUIREMENTS
The Remote Lockout system is not intended to replace good verbal radio communication. Radio communication
is essential to the Remote Lockout system process.
Use good quality two-way radios with sufficient range to provide clearly understood communication. Test radios
at the site to ensure communications can be heard above background noise.
The radio at the exit location must be assigned to one designated person. This person will always communicate
with the machine operator.
When sending a message, identify yourself and the receiver by name. This prevents confusion if more than one
machine is operating on a jobsite.
All radio messages must be confirmed by the receiver. Confirmation from the receiver must acknowledge that
the message was received and correctly understood. Correct understanding must be demonstrated by repeating
the original message back to the sender. The sender must always require confirmation of the message.
WARNING: Proper communication is essential to prevent unplanned startup of the
drill string and/or tool. Serious injury or death could result. Always follow
communication requirements as explained below.
