Chapter 85A - OCCUPATIONAL DISEASE COMPENSATION
Section 85A.7 - Limitations and exceptions.

85A.7 Limitations and exceptions.
The provisions of this chapter providing payment of workers’ compensation on account of occupational disease as defined and set out in this chapter, shall be subject to the following limitations and exceptions:
1. No compensation shall be payable if the employee, at the time of entering the employment of the employer in writing falsely represented to said employer that the employee had not been previously disabled, laid off or compensated, or lost time by reason of an occupational disease.
2. No compensation for death because of an occupational disease shall be payable to any person whose relationship to the deceased employee arose subsequent to the beginning of the first compensable disability, except only after-born children of a marriage existing at the beginning of such disability.
3. When such occupational disease causes the death of an employee and there are no dependents entitled to compensation, then the employer shall pay the medical, hospital and burial expenses as is provided by the workers’ compensation law, and shall also pay to the treasurer of the state for the use and benefit of the second injury compensation fund such amount as is required by the second injury compensation law.
4. Where such occupational disease is aggravated by any other disease or infirmity not of itself compensable, or where disability or death results from any other cause not of itself compensable but is aggravated, prolonged or accelerated by such an occupational disease, and disability results such as to be compensable under the provisions of this chapter, the compensation payable shall be reduced and limited to such proportion only of the compensation that would be payable if the occupational disease was the sole cause of the disability or death, as such occupational disease bears to all the causes of such disability or death. Such reduction or limitation in compensation shall be effected by reducing either the number of weekly payments or the amount of such payments as the workers’ compensation commissioner may determine is for the best interests of the claimant or claimants.
5. No compensation shall be allowed or payable for any disease or death intentionally self-inflicted by the employee or due to the employee’s intoxication, or due to the employee being a narcotic drug addict, or the employee’s commission of a misdemeanor or felony, refusal to use a safety appliance or health protective, refusal to obey a reasonable written or printed rule of the employer which has been posted in a conspicuous position in the place of work, or failure or refusal to perform or obey any statutory duty. The burden of establishing any such ground shall rest upon the employer.
6. No compensation shall be payable or allowed in any case where the last injurious exposure to the hazards of such occupational disease occurred prior to the effective date of this chapter.
