Claim 4:
5. A hazard prediction apparatus comprising:
an image acquisition unit configured to photograph an outdoor facility along with environment to capture an image;
a voice acquisition unit configured to receive an input of voice of a worker;
a display unit configured to display information to the worker;
a tool use control unit configured to restrict use of a tool; and
an information processing unit configured to connect the image acquisition unit, the voice acquisition unit, the display unit, and the tool use control unit,
wherein
the information processing unit includes:
a collation circuit configured to collate the image captured by the image acquisition unit with accident data including photos of outdoor facilities along with environment and accidents occurred at open-air facilities in the photos to detect, when a photo similar to the image is found, an accident occurred at an open-air facility in the photo from the accident data;

an extraction circuit configured to extract, from a safety measure list describing accidents, hazardous spots related to the accidents, and safety measures for prevention of the accidents, hazard information on a hazardous spot and a safety measure corresponding to the accident detected by the collation circuit;
a hazardous spot display circuit configured to cause the display unit to display the hazardous spot extracted by the extraction circuit;
an input circuit configured to receive input information that is a safety measure uttered by a worker for the hazardous spot displayed by the display unit, from the voice acquisition unit;
a checking circuit configured to compare the input information from the input circuit with the hazard information from the extraction circuit to check that the input information and the hazard information match each other; and
a control signal output circuit configured to output a signal to the tool use control unit when the input information and the hazard information match each other such that a tool is available and output a signal to the tool use control unit when the input information and the hazard information do not match each other such that a tool is unavailable.
