All amusement rides and devices in the state shall be inspected at least once in each calendar year, and as often as the Commissioner of Consumer Protection directs. The commissioner shall approve one or more qualified inspectors or civil engineers familiar with the construction and use of gravity and other amusement rides and devices to conduct such inspections. Such inspectors shall be certified to perform such inspections by a nationally recognized professional or trade association of amusement ride safety officials approved by the commissioner. A reasonable fee for such inspection, to be determined by the commissioner, shall be paid to such inspector or engineer by the owner, lessee or operator of such ride or device. No amusement ride or device used for the carrying of passengers shall be operated in the state unless the same has been inspected by such an inspector or engineer and the inspector or engineer has certified to the commissioner that, in such inspector’s or engineer’s judgment, the same is reasonably safe for public use. Any person aggrieved by the refusal of such inspector or engineer to grant such certificate of safety shall have the right of appeal to the commissioner, who may, after due hearing, if he is of the opinion that such ride or device is safe for public use, issue a license therefor. Upon receipt of such certificate, if the applicant has complied with the provisions of sections 29-129 to 29-143a, inclusive, a license shall be issued by the commissioner, and the commissioner may issue temporary licenses to operate such rides or devices pending inspection or final hearing upon the application when, in the commissioner’s judgment, fairness and equity require it.
