Notice of proceedings for compensation; limitation of actions

Section 41. No proceedings for compensation payable under this chapter shall be maintained unless a notice thereof shall have been given to the insurer or insured as soon as practicable after the happening thereof, and unless any claim for compensation due with respect to such injury is filed within four years from the date the employee first became aware of the causal relationship between his disability and his employment. In the event of death, no claim shall be made later than four years after the death. Where an action against a third person, as provided by section fifteen, is discontinued, no claim for compensation shall be made later than sixty days after such discontinuance. The payment of compensation for any injury pursuant to this chapter or the filing of a claim for compensation as provided in this chapter shall toll the statute of limitations for any benefits due pursuant to this chapter for such injury.
