b) for which occupational exposure limits have been established.
26.4.3.2 The aspects of the safety data sheet shall comply with the provisions of an official technical standard.
26.4.3.3 The provisions of 26.4.3.1 also apply to chemical products that are not classified as hazardous but whose intended or recommended use poses a risk to the safety and health of workers.
