Abstract

The present invention provides safety confirmation or hazard warning to a technician in the field, e.g., by scanning an equipment identification label and comparing the identification to a schedule of equipment inactivation times. The systems and methods of the invention can optionally provide remote interactions to reschedule inactivations or to protect the technician by lock-out from a hazardous condition.

Claims

1. A technician safety system comprising:

a portable computer comprising a scanner device;

software comprising a database of equipment maintenance information; and

,

one or more equipment identification labels readable by the scanner device and associated with a work site or piece of equipment;

whereby a technician can scan a label to receive a safety confirmation or a hazard warning.

2. The system of claim 1, wherein the portable computer comprises a hand held computer or a lap top computer.

3. The system of claim 1, further comprising one or more central computer comprising a communication port whereby the central computer communicates with one or more portable computers.

4. The system of claim 3, wherein the communication port comprises wireless communications.

5. The system of claim 1, further comprising a lock out device.

6. The system of claim 5, wherein the lock out device is remotely controlled by a central computer.

7. The system of claim 1, wherein the equipment maintenance information comprises equipment identifications, equipment locations, technician identification, technician qualifications, equipment maintenance schedules, equipment inactivation times, process requirements for equipment activation, or equipment maintenance histories.

8. The system of claim 1, wherein the identification labels comprise bar-coded information.

9. A method of work environment safety determination, the method comprising:

inputting equipment maintenance information into a computer system, which information comprises equipment inactivation times;

scanning an identification label associated with a piece of equipment or work site, thereby inputting an equipment identification into the computer system; and

,

determining the safety of the work environment by comparing the equipment identification to a current time and scheduled inactivation times, a safety checklist, or a database of monitored values.

10. The method of claim 9, further comprising providing a safety confirmation if the current time corresponds to an inactivation time for the identified equipment.

11. The method of claim 9, further comprising providing a hazard warning if the current time does not correspond to an inactivation time for the identified equipment.

12. The method of claim 9, wherein the computer comprises a portable computer.

13. The method of claim 9, wherein identifying comprises scanning a bar-coded label associated with the equipment or work site.

14. The method of claim 9, wherein inputting the equipment identification comprises transmitting equipment identification from a portable scanner to a central computer.

15. The method of claim 14, wherein the transmitting comprises wireless communication.

16. The method of claim 9, further comprising engagement of a lock-out mechanism at the work environment if a hazard warning condition exists.

17. The method of claim 9, further comprising:

inputting technician qualification information into the computer;

inputting technician identification into the computer;

inputting workplace entry requirements into the computer;

and confirming the identified technician is qualified to enter the work environment by comparing the technician identification, the technician qualifications and the entry requirements.

18. The method of claim 17, wherein inputting technician identification comprises input of a password.

19. The method of claim 17, further comprising engaging a lock-out condition if the technician qualifications do not meet the work environment entry requirements.

20. The method of claim 9, further comprising inputting task completion information in the computer to document compliance with regulations and schedules.
