If he is under ESIC, they will give him the compensation as per the law.
He can also approach the management for coverage and benefit available under the company's public liability insurance and group accident insurance policy.

Dear Colleague,
If the subjected person was covered under Employees State Insurance, the due compensation will be paid to him provided the Organization has to file Accident Report on Line in the ESI Portal. The witness statement, treatment records, Photos if any taken, report from Supervisor in charge and so on to be kept ready for inspection by the ESI Local Office Manager apart from the Attendance Register, Wage Register etc. Upon satisfactory inspection at the Organization the ESIC will take up the matter for settlement of due compensation as applicable to the nature of injury to the person. Kindly approach the Management and Local Office Manager of ESIC for necessary support.
