(A) Notwithstanding any other provision of law, with respect to any asbestos or silica claim not barred as of the effective date of this chapter, the limitations period shall not begin to run until the exposed person or claimant discovers, or through the exercise of reasonable diligence should have discovered, that the exposed person or claimant is physically impaired as set forth in this chapter by an asbestos- or silica-related condition.

(B) An asbestos or silica claim arising out of a nonmalignant condition shall be a distinct cause of action from an asbestos or silica claim relating to the same exposed person arising out of asbestos- or silica-related cancer, and resolution of an asbestos or silica claim arising out of a nonmalignant condition shall not affect the ability of the same exposed person to bring a separate asbestos or silica claim arising out of an asbestos- or silica-related cancer, that otherwise meets all the requirements of § 44-135-50 or 44-135-60.
