The term "imminent danger" refers to a situation where there is an immediate and significant threat to someone's life, health or safety. This can include situations such as being in physical peril due to a hazardous condition, facing an ongoing threat of harm, or experiencing an emergency that requires immediate action to prevent injury or death. The concept of imminent danger is often used in legal contexts to establish grounds for taking protective measures or seeking justice, and it can also be applied in other areas such as workplace safety or disaster preparedness.
