(a) As soon as practicable, but within 30 days after occurrence of an injury covered by the Act, or within 30 days after an employee becomes aware, or in the exercise of reasonable diligence should be aware, of the relationship between an injury or disease and his employment, the injured employee or someone on his behalf shall give written notice thereof to the district director having jurisdiction over the place where the injury occurred and to the employer.

Notice shall be given:  (1) To the district director in the compensation district in which the injury or death occurred, and (2) to the employer.
