Employers must post injury, illness summary by Feb. 1

January 18, 2019

Washington — Employers required to keep and maintain an OSHA 300 injury and illness log must post their 300A summary sheet in the workplace from Feb. 1 to April 30.

Form 300A summarizes work-related injuries and illnesses recorded in 2018. OSHA states that the summary must be posted in common work areas where employee notices are customarily placed.

The agency notes that employers with 10 or fewer employees or who work in certain low-hazard industries are not required to post the summary.
