Technological hazard

Technical or technological disasters are caused by events that can be intense and sudden, induced by human processes. They originate from technological or industrial conditions, dangerous procedures, infrastructure failures or specific human activities (UNGA, 2016).

Technical systems are complex, with many dependent subsystems. The failure of one element within this system can cascade throughout the chain, causing a series of failures leading to a disaster. Technical hazards are increasing due to the scope of technological expansion. They include industrial activity that includes dangerous conditions, processes, all transport systems (land, sea, air), defensive or offensive weapons systems and power plants.

By 2050, most of humanity will live downstream of large dams built in the 20th century.

A new set of emerging technological risks under the Sendai Framework includes Information and communications technology (ICT)-related hazards. The increasing dependence upon complex large-scale network architectures of information technologies also increases exposure to cybersecurity threats. These threats include computer viruses, worms, Trojan horses, malware, spoofing attacks, identity theft, the theft and illegal disclosure of data, the loss of data and contamination of data. They have the potential to disrupt essential infrastructure operations such as communication, health, banking, transportation, energy, education and many other services.

Risk factors

  • Ageing, abandoned or idle installations.
  • Insufficient institutional and legal capacities.
  • Natural hazards: storms, landslides, floods or earthquakes can cause industrial accidents.

Vulnerable areas

  • Residential communities around industrial establishments tend to be most at risk because of their proximity.

Risk reduction measures

  • Assess the risks before planning and building critical infrastructure.
  • Develop policies and practices for continuity management.
  • Integrate the risks into planning, foresee and reduce cascading effects.
  • Create a hazard map to identify people at risk and their vulnerability.
  • Draft national, regional and local response plans.
  • Put in place early warning/monitoring systems to inform response.
  • Ensure contingency and response plans are in place at a national and local level to evacuate people on time.
  • Assess new technologies.
  • Improve crisis communication before, during and after the event.
  • Organize training and exercises for complex scenarios involving multiple interdependent failures.
  • Educate and raise awareness on potential risks.

Japan's nuclear crisis escalated to its worst level in two years on Wednesday, with its nuclear watchdog saying it feared more tanks were leaking contaminated water and China expressing its shock over the disaster. The plant's operator has been criticised for its failure to prepare for the disaster, and Japan's Chief Cabinet Secretary has said the government 'will make every effort to halt the leak'...

If an another strong earthquake strikes Japan's Fukushima nuclear plant before the fuel is fully removed that topples the building or punctures the pool and allow the water to drain, a spent fuel fire releasing more radiation than during the initial disaster is possible, threatening Tokyo 200 kilometres away. Meanwhile Tepco, the operator of the plant is considering risks and countermeasures...

Yousry Abushady, a senior inspector at the IAEA explains that three factors are closely considered by any country when building a nuclear reactor: active geological fault lines, water availability and population density. 'There has not been a single case in history where a nuclear reactor has been directly affected by an earthquake,' he says. 'Nuclear power stations cope well with earthquakes'...

The bauxite residue container pond in Almásfüzitő, Hungary has been declared to be one of the most threatened areas by Prime Minister Viktor Orbán on Thursday. Although the flood protection dikes are unarguably high, Greenpeace is concerned that dangerous substances may seep into the Danube with the elevated ground water levels, as it has been discussed in recent scientific publication...
