Differentiate hazards and disaster. What are the steps involved in hazard assessment? Explain
Hazards and disasters are terms frequently used in environmental and occupational safety, but they refer to different concepts. Understanding their distinctions and the process of hazard assessment is crucial for effective risk management in both environmental and occupational contexts.
### Hazards vs. Disasters
A hazard is any condition, event, or situation that has the potential to cause harm or damage to people, property, or the environment. Hazards can be natural (e.g., floods, earthquakes, and wildfires) or human-made (e.g., chemical spills, industrial accidents, and environmental pollution). Hazards are typically assessed in terms of their likelihood of occurrence and the severity of their potential impact.
On the other hand, a disaster is the actual realization or occurrence of a hazard that causes significant damage or harm. A disaster results when a hazardous event escalates beyond the capacity of individuals or communities to cope with it. Disasters can be sudden, like an earthquake, or they can develop over time, such as in the case of long-term environmental degradation or occupational diseases resulting from exposure to hazardous materials. Essentially, while hazards represent the potential for harm, disasters are the outcomes that result when those hazards turn into actual events.
For example, a hazardous substance like asbestos poses a threat to workers exposed to it over long periods. If the exposure results in a disease like mesothelioma, it becomes a disaster for the affected individual. However, asbestos in itself is merely a hazard until it causes significant harm.
### Steps Involved in Hazard Assessment
Hazard assessment is a systematic process of identifying, analyzing, and evaluating the risks associated with hazards. It involves several steps to ensure that risks are minimized and that effective safety measures are put in place to prevent potential disasters. Below are the key steps involved in hazard assessment:
