Worker safety management system

A method for managing worker safety in a work place including a delimited work area containing a work machine that could be a source of danger according to safety management information stored in an ID tag carried by each worker, wherein:

• the safety management information stored in each ID tag includes a work area code indicating a work area permitted to the corresponding worker and a danger avoiding capability code indicating a danger avoiding capability of the worker,
• the danger avoiding capability indicated by the danger avoiding capability code being determined from a worker skill of the corresponding worker that is evaluated in a standardized manner from past work experience of the corresponding worker and credits earned in a safety education program, and a specific degree of danger in the work area permitted to the worker;
• the method comprising:
• a worker presence information generating step of generating a worker presence information of the work area containing the work machine according to records of worker entry and worker exit;
• a worker absence control executing step of executing a worker absence control when a worker absence is determined from the worker presence information generated by the worker presence information generating step;
• and
• a worker presence control executing step of executing a worker presence control when a worker presence is determined from the worker presence information generated by the worker presence information generating step;
• wherein the worker absence control executing step permits a worker an access to a work area provided that the worker is verified to be permitted to work in the work area according to the worker's work area code and that a danger avoiding capability indicated by the worker's danger avoiding capability code is equal to or higher than a degree of danger associated with a work machine included in the work area;
• and
• wherein the worker presence control executing step permits a worker an access to a work area provided that the worker is verified to be permitted to work in the work area according to the worker's work area code and that a danger avoiding capability indicated by the worker's danger avoiding capability code is equal to or higher than a danger avoiding capability indicated by a danger avoiding capability of a worker already present in the work area based on the worker presence information generated by the worker presence information generating means;
• whereby safety of the worker who seeks an access to the work area containing the work machine is ensured.

• and
• a worker presence control executing step of executing a worker presence control when a worker presence is determined from the worker presence information generated by the worker presence information generating step;
• wherein the worker absence control executing step enables a start operation command, a stop operation command and a change operation mode command of the work machine;
• and
• wherein the worker presence control executing step enables a start operation command, a stop operation command and a change operation mode command of the work machine for a change to an operation mode involving a lower degree of danger but prohibits a change operation mode command of the work machine for a change to an operation mode involving a higher degree of danger;
• whereby safety of the worker is ensured when issuing any of a start operation command, a stop operation command and a change operation mode command.
