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.

Update

Given the slew of building collapses in Nigeria, experts from the Nigerian Institute of Town Planners have recommended identifying distressed buildings and removing occupants, while also reviewing legislation and codes. Some experts have also called attention to potential government corner cutting sought to accommodate builders' and political interests.

Independent Newspapers Limited
Update

Following the collapse of a building last week on Lagos Island, professionals in Nigeria's built environment have noted that shoddy building construction arising from the use of sub-standard materials has fuelled collapses. The experts insist that enforcement of the building code and other structural safety measures will prevent future disasters.

Rapidly expanding hydropower development in areas prone to geological and hydro-climatic hazards poses multiple environmental and technological risks. Yet, so far these have received scant attention in hydropower planning processes, and even in the

Multidisciplinary Digital Publishing Institute
Update

Despite growing climate threats, politicians and developers are ignoring geological and environmental risks in a rush to make short-term profits by building hydroelectric dams in the Himalayas. With northeast India already showing the dangers of rushing dam production and sidelining locals, there are concerns that the dams will perpetuate a history of failures.

FireCheck, a new fire hazard mapping and modeling project, will help authorities facilitate assessments and determine where flames may spread in the Philippines. FireCheck's maps also help identify dense residential areas in at-risk cities. Researchers have also developed an app that can display the information needed for pre-fire response planning in a community.

Since 1986 a lot has happened: the focus has shifted from the management of disasters to the more proactive management of risks - in a multi-hazard, multi-stakeholder and fully integrated fashion.
Update

After a confluence of factors triggered the Chernobyl disaster, the Soviet government initially downplayed the scale of the event and stifled communication that could expose damages. With the land still inhabitable for at least 20,000 years, there is concern that modern autocratic regimes that are pursuing nuclear programmes will repeat the same mistakes.
