7 Eulogy Mr. M. Nithiyananthan, the nodal investigator on the safety components of this project, tragically passed away in January 2009, before he could see this wonderful publication in print. Nithi, as he was affectionately called by his colleagues, was unusual in many ways. His main profession, that of a safety engineer at the Chennai Port Trust, was one that demanded strict enforcement often to the annoyance of his workers. He was known as a man of action during his career. After his retirement, he engaged in safety assessments with such a degree of compassion that it would be hard to capture his enthusiasm in a few paragraphs. He was very gratified that all the knowledge he had painstakingly acquired but yet could only use for enforcement at one organization could finally find a place in the academic or awareness raising domains of safety engineering. He wanted this wealth of information accrued during routine project assessments be compiled in systematic ways and made available freely so that the wheel doesn’t have to be reinvented repeatedly. The present findings in the stone quarrying sector represent one of his best such efforts. He wanted to “show and tell” how things could be improved at little cost but huge savings for health and life. He endured extreme temperatures, swaying temperaments of owners and workers, hazardous work place conditions with extra-ordinary patience just so that the unsafe conditions could be showcased and eventually done away with. He has meticulously documented the hazards and listed the accompanying solutions through a masterly photo collection. The project staff will remember his efforts with heartfelt gratitude not only for the scientific contributions but also for serving as a role model for human compassion and dedication. We dedicate this manual in his loving memory. Kalpana Balakrishnan Department of Environmental Health Engineering Sri Ramachandra University Chennai, India
