Colorado Revised Statutes Title 8. Labor and Industry § 8-41-207. Death after two years

In case death occurs more than two years after the date of receiving any injury, such death shall be prima facie presumed not to be due to such injury; such presumption shall not apply in cases of silicosis, asbestosis, anthracosis, or disability or death resulting from exposure to radioactive materials, substances, or machines or to fissionable materials, or any type of malignancy caused thereby, or from poisoning by uranium or its compounds. In all other cases, such presumption may be rebutted by competent evidence.
