(g) providing the worker with a result representing bar code representing the result of selection by the worker of the specified material from the plurality of materials with reference to the work slip, (h) the worker causing a bar code reader to read the result representing bar code and the work instruction bar code, (i) transferring reading signals from the bar code reader of step (h) to the work control computer, (j) the work control computer collating the work instruction bar code and result representing bar code reading signals of step (i), (k) notifying the worker whether the result of collation is appropriate, and (i) indicating to the worker the container for the worker to place the selected material in.

Claim 7

A method of preventing human error in a work procedure which includes a procedure for selecting at least one specified material from a plurality of materials and a procedure for placing the selected material into at least one specified container, comprising the steps of: (a) providing a work slip to a worker indicating work data as to the work procedure to be performed in a form readable by the worker and with a work instruction bar code representing the work data, (b) the worker selecting a specified material from a plurality of materials with reference to the work slip, (c) providing the worker with a material representing bar code representing the selected material, (d) the worker causing a bar code reader to read the material representing bar code and the work instruction bar code, (e) a work control computer collating signals from the bar code reader to step (d), (f) notifying the worker if the selected material is appropriate. (g) providing the worker with a result representing bar code representing the result of selection by the worker of the specified material from the plurality of materials with reference to the work slip, (h) the worker causing a bar code reader to read the result representing bar code and the work instruction bar code, (i) transferring reading signals from the bar code reader of step (h) to the work control computer, (j) the work control computer collating the work instruction bar code and result representing bar code reading signals of step (i), (k) notifying the worker whether the result of collation is appropriate, and (i) indicating to the worker the container for the worker to place the selected material in.

Claim 10

A method for preventing human error in preparing a composition, comprising the steps of: (a) providing a work slip to a worker having human readable work data and a work instruction bar code representing the work data; (b) providing at least one container having an additive therein and an additive indicating bar code thereon indicating the additive; (c) the worker selecting one of said at least one container and using a bar code reader to read both said additive indicating bar code of the selected container and said work instruction bar code; (d) a work control computer collating the signals from the bar code reader of step (c); (e) notifying the worker if the container selected is appropriate; (f) placing the additive in the container within a transport container; (g) measuring the transport container; (h) notifying the worker if the measurement is appropriate; (i) applying a measurement representing bar code label to the transport container if the measurement is appropriate, the measurement representing bar code label including indication of (1) the additive, (2) a tank destination, and (3) the measurement result; (j) indicating the tank designation to the worker; (k) the worker using a bar code reader to read the work instruction bar code and to read the measurement representing bar code label; (l) the work control computer collating the signals from the bar code reader of step (k); (m) notifying the worker if the result of collation is appropriate; and (n) the worker placing the additive in the transport container into the designated tank if step (m) indicates that the result of collation is appropriate.

Claim 11

A method for preventing human error in preparing a composition, comprising the steps of: (a) providing a work slip to a worker having human readable work data and a work instruction bar code representing the work data; (b) providing at least one container having an additive therein and an additive indicating bar code thereon indicating the additive; (c) the worker selecting one of said at least one container and using a bar code reader to read both said additive indicating bar code of the selected container and said work instruction bar code; (d) a work control computer collating the signals from the bar code reader of step (c); (e) notifying the worker if the container selected is appropriate; (f) placing the additive in the container within a transport container; (g) measuring the transport container; (h) notifying the worker if the measurement is appropriate; (i) applying a measurement representing bar code label to the transport container if the measurement is appropriate, the measurement representing bar code label including indication of (1) the additive, (2) a tank destination, and (3) the measurement result; (j) indicating the tank designation to the worker; (k) the worker using a bar code reader to read the work instruction bar code and to read the measurement representing bar code label; (l) the work control computer collating the signals from the bar code reader of step (k); (m) notifying the worker if the result of collation is appropriate; and (n) the worker placing the additive in the transport container into the designated tank if step (m) indicates that the result of collation is appropriate.
