Safety warning system

A safety warning system including:

• at least one sensor or sensor system to detect an abnormal safety situation that is occurring or is about to occur within a safety zone, the at least one sensor or sensor system detecting a parameter, in relation to an object for comparison relative to a safety setpoint for that parameter;
• at least one network transmitter to cause the at least one sensor or sensor system, to issue an alert signal based on the comparison, wherein the at least one network transmitter establishes a self-contained safety zone network limited to the safety zone and which is independent of both outside infrastructure and access to external communications platforms for operation;
• at least one network controller to coordinate the at least one sensor or sensor system to receive information from the at least one sensor or sensor system and issue the alert signal based on the comparison of the information received and the safety setpoint, the alert signal issued over the self-contained safety zone network;
• and
• at least one wearable unit provided for each user in the safety zone, the wearable unit providing at least a tactile alert to the user based on the comparison to warn the user of the occurrence of the abnormal safety situation that is occurring or is about to occur within the safety zone;
• wherein the at least one, and typically a number of sensors, are used to create a geo-fence about the safety zone and a location or positioning system is used in order to allow the system to pinpoint the location of users through their wearable units and alerts are issued dependent upon the particular location of users within the safety zone;
• wherein the at least tactile alert to the user is in the form of a haptic or vibration alert based on alerting the user through a sense of touch.
