Employers who are required to keep Form 300, the Injury and Illness log, must post Form 300A, the Summary of Work-Related Injuries and Illnesses, in a workplace every year from February 1 to April 30. Current and former employees, or their representatives, have the right to access injury and illness records. Employers must give the requester a copy of the relevant record(s) by the end of the next business day.
Employers with more than ten employees and whose establishments are not classified as a partially exempt industry must record work-related injuries and illnesses using OSHA Forms 300, 300A and 301, available here. Partially exempt industries include establishments in specific low hazard retail, service, finance, insurance or real estate industries and are listed in Appendix A to Subpart B and here.
If you do not have that form you can access it by following the links above.
You need to post it ASAP.
