Ohio Rev. Code § 3743.56
Each fireworks exhibitor licensed under section 3743.51 of the Revised Code shall register annually with the fire marshal all employees who assist the licensed exhibitor in conducting fireworks exhibitions. Once registered, such an employee may be employed by any other licensed fireworks exhibitor, without the need for that other licensed exhibitor to register the employee with the fire marshal. The fire marshal shall maintain a record of licensed exhibitors and registered employees and make it available, upon request, to any law enforcement agency.
The fire marshal shall adopt rules under Chapter 119. of the Revised Code that establish appropriate fees for the registration of employees of licensed exhibitors and otherwise implement this section.
In addition to the annual registration of employees required by this section, a licensed exhibitor shall file an application to register a new employee, unless the new employee is already registered under this section, not later than seven days after the date on which the employee is hired.
Each applicant for registration under this section shall provide fingerprint or similar identifying information to the fire marshal for the purposes of determining applicant compliance with section 3743.70 of the Revised Code. The fire marshal may adopt rules under Chapter 119. of the Revised Code specifying the method to be used by the applicant to provide the fingerprint or similar identifying information, fees to be assessed by the fire marshal to conduct such background checks, and the procedures to be used by the fire marshal to verify compliance with this section. Such rules may include provisions establishing the frequency that license renewal applicants must update background check information filed by the applicant with previous license applications and provisions describing alternative forms of background check information that may be accepted by the fire marshal to verify compliance with this section.
