Which of the following is classified as a man-made disaster?

Appeared in: HPSSC - 2015

Explanation

A major chemical spill from a train derailment is a classic example of a man-made disaster, also referred to as a technological or human-induced disaster.
These events are caused by human error, negligence, or the failure of man-made systems, such as transportation infrastructure or industrial plants.
The train derailment and subsequent spill are a direct result of human activity and technology, not a natural environmental process.

Option A: A hurricane is a powerful tropical cyclone, which is a meteorological event. It is caused by natural atmospheric and oceanic conditions, not by human action.
Option C: A volcanic eruption is a geophysical event where magma and gases are released from a volcano. This is a natural process related to the Earth's geology.
Option D: An earthquake is a geophysical event caused by the sudden movement of tectonic plates in the Earth's crust. It is a purely natural phenomenon.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Disaster Classification: Natural vs. Man-made as background academic context rather than a clinical decision trigger.
Nurses must be able to differentiate between disaster types to anticipate the health consequences and required response. For example, a chemical spill requires knowledge of toxicology and decontamination, whereas an earthquake response focuses on trauma care.
Disaster preparedness plans in healthcare facilities are tailored to different disaster types, including specific protocols for handling casualties from man-made events like chemical, biological, radiological, or nuclear (CBRN) incidents.
What if? If an earthquake (natural disaster) caused the collapse of a chemical factory, releasing toxic substances, it becomes a complex disaster with both natural and man-made components. The response would need to address both trauma care for earthquake victims and specialized care for chemical exposure.

How to Approach the Question

First, understand the core of the question, which is to identify the definition of a 'man-made disaster'.
Define 'man-made disaster' as an event caused by human action, error, or technological failure, as opposed to a 'natural disaster' caused by environmental forces.
Evaluate each option against this definition.
A hurricane, volcanic eruption, and earthquake are all natural phenomena. Eliminate these options.
A chemical spill from a train derailment is a result of a failure in a human-created system (transportation and chemical handling). This fits the definition of a man-made disaster.
Therefore, select the option describing the chemical spill.
