Hazards global

Global hazards can be mitigated through targeted molecular design. Uncovering the mechanism of ozone reduction by chlorine, and specifically by chlorofluorocarbons, has led to research chemicals that had minimal impact on stratospheric ozone. 

Global warming and ozone depletion are the two primary global hazards associated with chemicals production and use. Chemicals that have structural features capable of absorbing infra-red radiation have the potential to contribute to global warming (see Table 2.4). ... 

Another problem is the extent of regulative measures. On the one hand, the use of asbestos is now almost completely banned in the European Union and in many other industrialised and economically thriving countries. On the other hand, more than 2 milhon tons of asbestos are extracted and consumed globally every year. A uniform global hazardous substances pohcy evidently does not exist yet. 

Global hazard examines adverse consequences that occur on a larger scale area and include stratospheric ozone depletion and effects of chemicals on global climate change. 

The internal routine, identify-potential-hazard, called from GLOBAL-HAZARD-IDENTIFICATION, retums a potential hazard and the list of the enabling conditions. The algorithm for identify-potential-hazard, expressed in pseudocode, is given below ... 

As SCHC s interests broadened to global hazard communication, international speakers were invited to SCHC meetings. A speaker from the United Kingdom (UK) Health and Safety Executive believed that hazard communication in the UK could benefit from a similar organization. SCHC provided infro-mation about forming a society. In 1994 a group of hazard communication professionals in the UK formed the Chemical Hazards Communication Society (CHCS). (http //www.ches.org.uk). 

Consequently all NeSSI components - including transducers, wiring systems, optical systems, enclosures - must be designed to meet the various global Hazardous Location standards. The NeSSI specification favors the use of Division 1 (Zone 1) rated equipment inside equipment enclosures which handle hazardous (flammable) fluids. Designing to this capability, although more stringent than...
