"This code of practice has been prepared to help those responsible for improving safety and health standards and to provide guidelines for the drafting of safety and health regulations for the coalmining industry. It contains provisions on general safety and health measures, specific measures for work underground, road and shaft driving, coal-getting, transport, etc., and procedures for the control of dust, firedamp, fire and other hazards. Local circumstances and technical facilities will determine how far it is practicable to follow these provisions."

"Given that 60 per cent of the global workforce is in the informal sector, this article develops a typology that classifies economies according to, firstly, where different countries sit on a continuum of informalization and, secondly, the character of their informal sectors. This is then applied to the economies of the 27 member states of European Union (EU-27). Finding a clear divide from east to west and south to north in the EU-27, with the more informalized and wage-based informal economies on the eastern/southern side and the less informalized and more own-account informal economies on the western/Nordic side, it is then revealed that formalization and more own-account informal sectors are significantly correlated with wealthier and more equal (as measured by the gini-coefficient) countries in which there is greater labour market intervention, higher levels of social protection and more effective redistribution via social transfers. The article concludes by discussing the implications for theory and practice."

Several quantitative risk assessment models have been published for occupational and environmental exposures to diesel exhaust particles (DEP). These risk assessment models are reviewed and applied to predict lung cancer risks for miners exposed to DEP. The toxicologically based unit risk estimates varied widely (from 2 to 220 ? 10-6 per g/m3). The epidemiologically based unit risk estimates were less variable and suggest higher risks (from 100 to 920 ? 10-6 per g/m3). The wide range of risk estimates derived from these analyses reflects the strong assumptions and large uncertainties underlying these models. All of the models suggest relatively high risks (i.e., >1/1,000) for miners with long-term exposures greater than 1,000 g/m3. This is not surprising, given the fact that miners may be exposed to DEP concentrations similar to those that induced lung cancer in rats and mice, and substantially higher than the exposure concentrations in the positive epidemiologic studies.

"Who should use this publication?
If your mine uses diesel-powered equipment, or is contemplating its use, you will find this Toolbox to be a useful guide. So too will those who help mine operators select or maintain mining equipment. The Toolbox can be read cover-to-cover as a basic reference, or used as a troubleshooting guide by diesel equipment operators and mechanics. Some knowledge of engines is assumed, although a glossary is provided. ..."
