Section 820 ILCS 255/8 - Labels, placards, signs and operating instructions identifying toxic substances(a) Except as otherwise provided by this Section, the employer shall label with the chemical name and appropriate hazard warnings each container of a toxic substance in the workplace. The employer is not required to label any container of ten gallons or less in volume into which a toxic substance or mixture is transferred by the employee from labelled containers and which is intended only for the immediate use of the employee who performs the transfer.(b) The employer may post signs, placards or operating instructions to convey the required information as specified in Section 8(a) rather than affixing labels to each fixed container. For purposes of this paragraph, "fixed container" shall mean a pipe, piping system, reaction vessel or storage tank. All containers which are not fixed containers must be individually labelled. The employer shall provide at least one sign, placard or set of operating instructions readily accessible to each employee in the employee's work area.(c) The employer shall ensure that each label, sign, placard or set of operating instructions required by this Section is prominently affixed and displayed in such a manner that employees can easily identify the toxic substances present.(d) The employer need not affix new labels if existing labels already convey the necessary information required by this Section.(e) This Section shall not apply to containers into which products registered pursuant to the Federal Insecticide, Fungicide and Rodenticide Act, as amended, are transferred to form use-dilutions at a mixing/loading site for use within a 12 hour period. All labeling information required for such products by the Federal Insecticide, Fungicide and Rodenticide Act must be posted in a prominent location at the mixing/loading site.(f) This Section shall become effective with respect to any toxic substance upon filing, unless a later effective date is specified in the rule, pursuant to Section 4(e) of this Act.
