1. A collaborative-robot risk assessment guidance device, comprising:
a storage configured to store work type information, peripheral environment information, and conditions for collaborating with people;
a display; and
a processor connected to the storage and the display, wherein the processor is configured to:
receive, from the storage, the work type information, the peripheral environment information, and the conditions for collaborating with people;
read out a plurality of hazard sources stored in the storage in association with the received work type information, the peripheral environment information, and the conditions for collaborating with people,
display the plurality of hazard sources on the display,
prompt a user to select at least one hazard source of the plurality of hazard sources,
receive the selected at least one hazard source,
prompt the user to select a harm, a situation, and a trigger associated with the selected at least one hazard source,
perform a risk assessment based upon a magnitude of injury and a possibility of accident occurrence determined from the harm, the situation, and the trigger,
determine whether a result of the risk assessment is at or below an acceptable risk,
display, on the display, countermeasure proposals in a case in which the result of the risk assessment is not at or below the acceptable risk, and
prompt the user to reconsider the work type information, the peripheral environment information, and the conditions for collaborating with people, wherein the risk assessment is repeated until the result of the risk assessment is at or below the acceptable risk.
