Major accidents refer to significant incidents that result in substantial damage, injury, or loss of life. These events can occur in various settings, including transportation, industrial sites, and natural disasters. Examples include train derailments, plane crashes, and chemical spills, which often require emergency response and can have long-lasting effects on communities and the environment. The impact of major accidents can extend beyond immediate casualties, leading to economic losses and changes in regulations. For instance, the Deepwater Horizon oil spill in 2010 caused extensive environmental damage and prompted new safety measures in the oil drilling industry. Such incidents highlight the importance of safety protocols and preparedness.
