Kan. Stat. § 44-5a15
Where an employee, though not actually disabled, is found to be affected by any occupational disease such employee may, subject to the approval of the director of workers' compensation be permitted to waive in writing full compensation for any aggravation of such condition that may result from continuing in the hazardous occupation. In the event of total disablement or death as a result of the disease with which the employee or worker was so affected, after such a waiver, compensation shall nevertheless be payable as herein elsewhere provided, but in no case, whether for disability or death or both, for longer than one hundred (100) weeks. A waiver so permitted shall remain effective, for the trade, occupation, process or employment for which executed notwithstanding a change or changes of employer. The director of workers' compensation shall make reasonable rules and regulations relative to the form, execution, filing, or registration and public inspection of waivers or records thereof.
