Safety rules prescribed by the pool.

Any servicing carrier shall administer and enforce reasonable regulations adopted by the board, subject to the superintendent's approval, for the prevention of injuries to employees of its assigned policyholders or any applicant for assignment for workers' compensation insurance. For this purpose, the representatives of any servicing carrier shall have free access to the premises of any assigned policyholder or applicant for assignment during regular working hours. The failure or refusal by any policyholder or applicant to comply with the safety regulations or to permit such access shall be sufficient grounds for determining whether the policyholder or applicant is, in good faith, entitled to workers' compensation insurance or to a surcharge or restrospective [retrospective] rate for continued coverage.
