Trenching and Excavation—Preventing Workplace Fatalities

Can We Reduce Workplace Fatalities by Half?

Singapore, an island republic of over 5 million inhabitants, has 3.1 million workers. Most are employed in the service, finance and tourist/transport industry. Significant numbers work in manufacturing, construction and heavy industry. Following a series of construction and shipyard accidents with multiple deaths in 2004, the government announced its intention to reduce workplace fatalities fro...

Estimating trenching costs in FTTx network planning

In this paper we assess to which extent trenching costs of an FTTx network are unavoidable, even if technical side constraints are neglected. For that purpose we present an extended Steiner tree model. Using a variety of realistic problem instances we demonstrate that the total trenching cost can only be reduced by about 5 percent in realistic scenarios. This work has been funded by BMBF (Germa...

Integrating geomorphological mapping , trenching , InSAR and GPR for the 1

13 This contribution illustrates the advantages of integrating conventional 14 geomorphological methods with InSAR, ground penetrating radar and trenching for 15 sinkhole mapping and characterization in a mantled evaporite karst area, where a 16 significant proportion of the karstic depressions have been obliterated by artificial fills. 17 The main practical aim of the investigation was to eluc...

Injuries and Fatalities

For nearly a decade, Purdue’s Agricultural Safety and Health Program has published an annual summary of U.S. grain-related entrapments 2 and engulfments. (www.grainsafety.us). These summaries are based on data gathered, documented, and entered into Purdue’s Agricultural Confined Space Incident Database (PACSID). With support from the U.S. Department of Labor over the past three years, the searc...
