This 1950s historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The image depicted `cutting oil', a type of metalworking fluid used to facilitate the cutting action of a cutting blade by lubricating the edge of the blade, as the oil was flowing unto the blade, and subsequently drained away. This activity was taking place in a tungsten carbide plant, and revealed the potential for the fluid to be sprayed in a haphazard manner, which warranted concern on behalf of any workers associated with the use of this machine to exposure to this cutting fluid. Activities such as this need stringent oversight by a regulating body such as NIOSH, which would make the health and welfare of such workers a paramount concern.No copyright. No rights reserved.
