Employee compensation claims require prompt notice and must be filed within two years, with specific occupational disease deeming rules. A compensation claim requires notice as soon as practicable and must be preferred within two years of the accident or death. Occupational disease occurrences are subject to deeming rules for continuous absence, partial disablement notice, and symptom detection after employment cessation. Defective or absent notice is excused where death occurred on employer premises or the employer had contemporaneous knowledge; competent authorities may extend time for sufficient cause. Notices must identify the injured person, cause and date of accident and be served on the employer or responsible manager; Governments may require a notice book and allow service by delivery, registered post, electronic means, or notice book entry.
