Online only we have to submit the accident report. Once you login to your ESIC Portal there left side top accident report (form 12) option will be there. Once you fill the report hard copy of the report you have to take and give it to employee. They needs to bring that along with company ID card and visit to esi office. IF you submit after 48 hours then you can't claim anything from ESIC. Do it ASAP.
