Accidental and Technological Hazards

Technical and accidental hazards can occur without warning and there is a possibility of a dangerous material accident and failure of nuclear power plants. In some cases, the victims exposed to harmful chemical substances or radiation have few symptoms after a few years. More and more new substances and chemicals are being produced, increasing the possibility of leakage or release of harmful substances. This also increases the risk to the health and safety of the environment and community.

Hazards are usually divided into three broad categories: nature, technology, and artificiality. Natural disasters are often related to weather and geological events such as floods, hurricanes, tornadoes, earthquakes, and so on. Technical hazards are human activities such as construction of dams and dams, manufacturing, transportation, storage and use of hazardous materials. Artificial hazards are often related to attacks by criminals or terrorists using weapons such as explosives, biological substances or chemicals. However, natural disasters can also become more complicated.

Research on technical hazards is an integral part of the multi-hazard approach to risk assessment. There are numerous studies and reports to identify and evaluate the risks of technical hazards. Various government agencies and private organizations are actively involved in risk assessment and mitigation plan. • Zoning as a form of land use management and management helps to regulate the development of population and residential, commercial and industrial in disaster prone areas. This can be used to control the density of the building, adjust the timing of the development plan, and define the "permission" development more clearly. As a first step, you need to use a map that identifies areas of high risk, and use it for development guidelines, restrictions, or restrictions. For example, flood insurance premium maps are used to define maps that restrict flood plains and coastal development.

• Hazard mapping and mapping are required to implement the frustration plan for land use management, zoning and registration. This will effectively address specific hazards. Models that identify hazardous areas need to be developed or tested to verify correctness. The danger of being drawn includes floods around lively volcanoes, lava flow and ash, avalanches, earthquake danger zones, landslides and ground subsidence. • Insurance does not directly alleviate hazard-related physical damage. However, it provides some economic protection through prepayment and loss of wider population. The National Flood Insurance Plan is the only program that provides flood hazard insurance nationwide. Other dangerous private insurance is available in certain areas, and some countries also participate in high-risk areas.
