Respiratory diseases that cause (i) the death of volunteer or salaried firefighters or Department of Emergency Management hazardous materials officers or (ii) any health condition or impairment of such firefighters or Department of Emergency Management hazardous materials officers resulting in total or partial disability shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary.

E. Persons making claims under this title who rely on such presumptions shall, upon the request of private employers, appointing authorities or governing bodies employing such persons, submit to physical examinations (i) conducted by physicians selected by such employers, authorities, bodies or their representatives and (ii) consisting of such tests and studies as may reasonably be required by such physicians. However, a qualified physician, selected and compensated by the claimant, may, at the election of such claimant, be present at such examination.

F. Whenever a claim for death benefits is made under this title and the presumptions of this section are invoked, any person entitled to make such claim shall, upon the request of the appropriate private employer, appointing authority or governing body that had employed the deceased, submit the body of the deceased to a postmortem examination as may be directed by the Commission. A qualified physician, selected and compensated by the person entitled to make the claim, may, at the election of such claimant, be present at such postmortem examination.
