Emergency refers to an unforeseen situation or occurrence that poses an immediate risk to health, life, property, or the environment, requiring swift action to prevent worsening conditions. Emergencies can arise from various sources, including natural disasters (such as floods or earthquakes), accidents (such as fires or vehicle collisions), medical crises (such as severe injuries or illnesses), and other urgent scenarios that demand quick response. The term is often associated with emergency services, which include police, fire, and medical personnel trained to handle such situations effectively. Responding to an emergency typically involves assessing the situation, providing immediate assistance, and implementing measures to mitigate the impact of the incident.
