    (a) The Director shall enforce the occupational safety and health standards and rules promulgated under this Act and any occupational health and safety regulations relating to inspection of places of employment, and shall visit and inspect, as often as practicable, the places of employment covered by this Act.
    (b) The Director or his or her authorized representative, upon presenting appropriate credentials to a public employer's agent in charge, has the right to enter and inspect all places of employment covered by this Act as follows:
        (1) An inspector may enter without delay and at
    
reasonable times any establishment, construction site, or other area, workplace, or environment where work is performed by an employee of a public employer in order to enforce the occupational safety and health standards adopted under this Act.
