Graphite safety measures

High temperature lubrication, as in some metal-forming processes, requites dry graphite. Although the coefficient of friction of graphite is higher than that of petroleum lubricants, it is often added as a safety measure should the carrier lubricant fail (17) (see Lubrication and lubricants).

Given that on the nanoscale, the properties of matter depend on size, it can be asked, how well do we understand the environmental health and safety risks of nanomaterials For example, can material safety data sheets developed for bulk graphite be used for nano-based carbon materials such as carbon nanotubes or buckyballs What necessary measures are needed to ensure that the implications of nanomaterials are well understood as these materials are developed and applied in a wide range of applications Furthermore, what can be done to reduce the uncertainties in our understanding of the environmental health and safety implications of nanotechnology ... 

This series of measurements was stimulated by criticality questions associated with the processing and handling of graphite-iiranium fuel for Rover reactors. It is directed specifically toward mixtures of this fuel with water or other hydrogenous material, in the hope of reducing large uncertainties attached to computed critical masses that had been used for safety guidance.
