(2) The emergency temporary standard is necessary to protect the employees from the danger described in paragraph (1).

(b) The Director shall adopt emergency temporary standards promulgated by the federal Occupational Safety and Health Administration within 30 days of the federal notice of proposed emergency rulemaking. An emergency temporary standard shall be effective until superseded by a permanent standard but in no event for more than 6 months from the date of publication of the emergency temporary standard. The publication of emergency temporary standards shall be deemed to be a petition to the Director for the promulgation of a permanent standard and shall be deemed to be filed with the Director on the date of publication. The proceeding for promulgation of the permanent standard shall be pursued in accordance with this Act.
