Hazard prediction activity system and hazard prediction activity method

Abstract

We provide a hazard prediction activity system that enables workers to conduct meaningful hazard prediction activities. [Solution] The work input unit 60 of the hazard prediction activity system 1 has a hazard prediction activity promotion unit 61 that, for a site identified by a worker operating the worker terminal 20, extracts the day's work from work processes registered in advance in the site information DB 40, extracts pre-check items corresponding to the day's work based on the information in the site information DB 40 and accident case information DB 50, creates a hazard prediction activity sheet based on the extracted pre-check items, sends questions to the worker terminal 20 to encourage the worker to engage in hazard prediction activities, receives answers to the questions entered from the worker terminal 20, and registers the answers in the hazard prediction activity sheet.

Claims

1. A hazard prediction activity system comprising a worker terminal used by workers and a hazard prediction activity server that stores the results of hazard prediction activities, A site information database in which information on work processes registered in advance for the work performed by the aforementioned workers at the site is stored, A database of accident case information that manages safety information related to the aforementioned site, It includes a work input unit that exchanges information with the worker terminal, The aforementioned work input unit has a hazard prediction activity promotion unit, The aforementioned Risk Prediction Activity Promotion Department, With respect to the site identified by the worker operating the worker terminal, the work for that day is extracted from the work process previously registered in the site information database. Based on the information in the aforementioned on-site information database and the aforementioned accident case information database, pre-check items corresponding to the work on the day will be extracted. Based on the extracted pre-check items, a hazard prediction activity sheet is prepared, and questions prompting the worker to engage in the hazard prediction activity are sent to the worker's terminal. The operator receives the answer to the question entered from the worker terminal. Register the above response in the aforementioned hazard prediction activity sheet. Hazard prediction activity system.

2. The hazard prediction activity promotion unit prompts the worker to engage in the hazard prediction activity at at least one of the following times: before the start of the work and after the completion of the work; has the worker consider the necessary countermeasures for the hazards anticipated in the hazard prediction activity; and registers the responses received from the worker's terminal through the hazard prediction activity into the hazard prediction information of the site information database for each site. The hazard prediction activity system according to claim 1.

3. The hazard prediction activity promotion unit generates a question prompting the worker to reconsider if the answer received from the worker terminal differs from the expected answer, and transmits the question to the worker terminal. The hazard prediction activity system according to claim 2.

4. The aforementioned work input unit includes an analysis unit that analyzes the results of the hazard prediction activity based on the responses received from the worker terminal and identifies the hazards reported at the site or countermeasures against those hazards. The hazard prediction activity system according to claim 3.

5. The Hazard Prediction Activity Promotion Unit generates a question that includes at least one of the following before the start of the work: name confirmation, work content, condition of clothing and protective equipment, confirmation of expected hazards and consequences of the work, and measures to eliminate the hazards, and transmits the question to the worker terminal. Based on the answers received from the worker terminal, the Analysis Unit calculates the current risk score and the score after the countermeasures are taken, and transmits the results of the identification of expected hazards to the worker terminal. The hazard prediction activity system according to claim 4.

6. The aforementioned work input unit includes a risk prediction unit that constructs an accident occurrence prediction model by learning the analysis results of past hazard prediction activities analyzed by the aforementioned analysis unit, and uses the prediction model to predict potential hazards at the site. The hazard prediction activity system according to claim 5.

7. The work input unit includes a training unit that provides training to enable workers to reproduce past hazard prediction activities based on the potential hazards at the site predicted by the risk prediction unit, or past hazard prediction activities. The hazard prediction activity system according to claim 6.

8. The worker terminal outputs the question transmitted from the work input unit as voice or text, and transmits the answer entered by the worker as voice or text to the work input unit. A hazard prediction activity system according to any one of claims 1 to 7.

9. Worker terminals used by workers, A site information database in which information on work processes registered in advance for the work performed by the aforementioned workers at the site is stored, A database of accident case information that manages safety information related to the aforementioned site, A work input unit that exchanges information with the aforementioned worker terminal, A method for conducting hazard prediction activities carried out in a hazard prediction activity system equipped with, The steps include: identifying the work site by operating the worker terminal on the worker terminal; The aforementioned work input unit includes the step of extracting the day's work from the work processes previously registered in the site information database for the work site, The aforementioned work input unit includes the step of extracting pre-check items corresponding to the work on the day based on the information in the site information database and the accident case information database, The work input unit creates a hazard prediction activity sheet based on the pre-check items and sends questions to the worker's terminal prompting the worker to carry out the hazard prediction activity; The process includes the step of receiving the answer to the question entered from the worker terminal from the worker terminal and registering the answer in the hazard prediction activity sheet. Methods for hazard prediction activities.
