The Occupational Safety and Health Administration (OSHA) 300A injury and illness summary form must be posted in a conspicuous workplace location by Feb. 1 and kept up until April 30.

The 300A is a summary of the information from the OSHA 300 injury and illness recordkeeping form (which shouldn’t be posted, just the summary form).

The summary form must be signed by a company executive to verify that the information is current and correct.


On Jan. 1 of this year, new OSHA reporting and recordkeeping requirements came into effect. To help you understand your new obligations, please order a copy of our OSHA Recordkeeping and Reporting Compliance Kit, which includes a guide, the forms you need, handouts and a CD-ROM.
