In nearly all cases, sand on a beach is enjoyable and safe. Sand used for sandblasting, however, creates dust that, upon being inhaled by an unprotected worker, increases the risk of lung disease or other lung-based medical concerns. The Louisiana Court of Appeal decided in Bates v. E. D. Bullard Co., that the possibility of problems does not make the sale of a product like sand unreasonable, especially when that use is outside the normal, non-technical purpose.
Wilbert Bates worked for the SBA Shipyards during the 1980s doing tasks that included cleaning and sandblasting. Both types of duties exposed him to silica dust — pieces of sand so small that he inhaled them and they stuck in his lungs that led to silicosis. Silicosis is an industrial disease that leaves its victims short of breath due to small sand particles becoming lodged in the lungs. The presence of particles encourages the growth of fibrous tissue in the lungs, reducing lung capacity. A lifetime of work can result in wheezing and body strain in an attempt to get air.
Bates and his wife sued Specialty Sand Co. and Southern Silica of Louisiana, Inc., which provided sand to the shipyard. The Bateses claimed that the sand was unreasonably dangerous or defective because the sand companies failed to warn and instruct him and the shipyard of the potential hazards.
