The employer shall ensure that each label is prominently affixed to the container or the piping system and displayed in such a manner that employees can easily identify the chemical in that container. These labeling requirements may be altered only in accordance with subsections (b), (d) and (f) or section 11. The employer shall not remove or deface existing labels on incoming containers of chemicals unless the container is immediately relabeled with the required information. The employer need not affix new labels to comply with this section if existing labels already convey the required information that the chemical or common name on the container is the same as that listed on the MSDS and can be used by the employee as a cross-reference to the MSDS. Any label may contain other information, including trade or brand name, provided the information required by this section is clearly legible. Nothing in this section shall require an employer to test any chemical to determine the accuracy of the label.
