Risks to construction workers include occupational hazards and accidents. There is particular vulnerability to accidents in this industry because turnover at very high levels does not allow for proper safety training or thorough implementation of safety procedures. Work with dangerous machines, with heavy loads in constant movement, and work in inclement outdoor weather, provide numerous opportunities for accidents. Occupational hazards include: noise; vibration; heat exhaustion; exposure to ultraviolet radiation from welding processes; lung diseases arising from cement and concrete dusts; and skin irritations, allergies and toxic reactions due to a variety of chemical hazards on the construction sites.
2005 data shows that in the construction industry, at least 60,000 fatal workplace accidents occur each year worldwide - or about one death every 10 minutes. About 17 per cent of all fatal workplace accidents occur in this sector, while construction workers also face a number of health risks, including exposure to asbestos-laden dusts, silica and hazardous chemicals.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
