Which of the following is NOT considered a personal precaution?

The reason why posting safety hazards is not considered a personal precaution is that it is more of a proactive measure aimed at creating awareness and promoting safety within a group or organization. This action is focused on informing others about potential dangers in the environment, ensuring that everyone is aware of the risks present.

In contrast, exercising caution, being careful, and ensuring that you are working under safe conditions are all personal precautions directly related to individual behavior and decisions. These actions emphasize the importance of a person’s own attentiveness and responsibility in maintaining a safe working environment. Each of these personal precautions requires an individual's active participation and vigilance to minimize risks to their own safety.
