(820 ILCS 219/30)
    Sec. 30. Standards; required features.
    (a) A standard promulgated under this Act shall prescribe the use of labels or other appropriate forms of warning as are necessary to ensure that employees are apprised of all hazards to which they are exposed, relevant symptoms and appropriate emergency treatment, and proper conditions and precautions of safe use or exposure.
    (b) When appropriate, a standard shall also prescribe suitable protective equipment and control or technological procedures to be used in connection with such hazards and shall provide for monitoring or measuring employee exposure at locations and intervals and in a manner as necessary for the protection of employees.
    (c) In addition, when appropriate, a standard shall prescribe the type and frequency of medical examinations or other tests which shall be made available, by the employer or at the employer's cost, to employees exposed to such hazards in order to most effectively determine whether the health of the employees is adversely affected by the exposure. The results of the examinations or tests shall be furnished by the employer only to the Department or, at the direction of the Department, to authorized medical personnel and, at the request of the employee, to the employee's physician.
    (d) The Director, in promulgating standards dealing with toxic materials or harmful physical agents under this Section, shall set the standard which most adequately ensures, to the extent feasible, on the basis of the best available evidence, that no employee will suffer material impairment of health or functional capacity even if the employee has regular exposure to the hazard dealt with by the standard for the period of the employee's working life.
    (e) Development of standards under this Section shall be based on research, demonstrations, experiments, and other information as appropriate. In addition to the attainment of the highest degree of health and safety protection for the employee, other considerations shall be the latest available scientific data in the field, the feasibility of the standards, and experience gained under this and other health and safety laws. Whenever practicable, a standard shall be expressed in terms of objective criteria and of the performance desired.
