When an operator must prepare an MSDS for a hazardous chemical produced at the mine, the MSDS must—
(a) Be legible, accurate, and in English;
(b) Use a chemical identity that permits cross-referencing between the list of hazardous chemicals, the chemical's label, and its MSDS; and
(c) Contain information, or indicate if no information is available, for the categories listed in Table 47.52 as follows:
