The initial discovery of the rare mineral deposit in India was on the western coast as placer deposits on beaches near Kollam, north of the capital city, Thiruvananthapuram in the coastal state of Kerala, India. Production of titanium dioxide commenced on these beaches in 1951. In the year 1909, the presence of the mineral monazite was observed in coir, a coconut fiber, shipped to Germany from India. He traced back to the place from where the coir was exported and this lead to the discovery of the deposits on the western coast of India, in the erstwhile princely state of Travancore. As thorium nitrate, a chemical produced from the mineral monazite was in good demand at that time for the production of mantles for gas lights, efforts started immediately for recovery of monazite from this deposit. Even though with the advent of electricity, the demand for gas lights and in turn that for thorium nitrate diminished, interest in these deposits continued since by that time technology developed for the production of titanium dioxide from the mineral Ilmenite. Titanium dioxide (TiO2), is a an insoluble white powder used extensively in many commercial products, including paint, cosmetics, plastics, paper and food, as an anticaking or whitening agent.

![Grain Elevator Dust Explosions c1980 OSHA
This was clipped from the video, Safety and Health Hazards in Grain Elevators, produced by OSHA about 1980, to help train OSHA inspectors investigating grain elevators. The entire video is posted to my YouTube channel. Catastrophic grain explosions in the late 1970s killing more than 60 workers and Federal USDA grain inspectors, focused national attention on hazards associated with the grain handling industry. This increased attention by the government, the grain industry and labor unions representing grain workers, led to safety improvements in the industry. The four factors that must be present in any explosive situation are well known and provide a useful framework for thinking about ways to eliminate explosions in grain elevators. The four factors are: fuel source in this case, grain dust. oxygen. ignition source. confinement (a condition that contributes to turning a fire into an explosion). Any measure proposed to reduce the incidence of grain dust explosions must effect changes in at least one of these four factors. In 1979, a General Accounting Office (GAO) report, Grain Dust Explosions An Unsolved Problem (http://www.gao.gov/products/HRD-79-1 ), investigated the grain dust explosion disasters of December 1977 and January 1978 and potential ways to prevent similar disasters. In this report, the GAO recommended that the U.S. Department of Labor evaluate the adequacy of its regulations to prevent grain elevators explosions. In 1987, OSHA issued its Grain Handling Facilities Standard (29 CFR 1910.272), which set mandatory minimum safety standards which maintains these improvements resulting in a 70% decrease in fatalities from grain explosions. On average, the Grain Handling Facilities Standard has prevented 5 deaths from explosions each year, according to the 2003 Regulatory Review of OSHAS Grain Handling Facilities Standard [29 CFR 1910.272] (https://www.osha.gov/dea/lookback/grainhandlingfinalreport.html ).
