Abstract
A communications assembly includes a central processing unit and a plurality of hardhat assemblies. The central processing unit transmits central signals and receives remote communications from the hardhat assemblies. The hardhat assemblies are operatively connected to the central processing unit in order to transmit the remote communications and receive the central communications. A communications hub is operatively connected between the central processing unit and each of the hardhat assemblies to control independent communication between the central processing unit and the hardhat assemblies. The central processing unit includes an incident identification module for receiving the remote communications and for identifying a portion of the remote communications from a portion of the hardhat assemblies as indicating a situation requiring a communication to be sent to the portion of the hardhat assemblies. The portion may include one or more than one hardhat assembly.
