Injury Tracking Application
The deadline for covered employers to report from their OSHA Form 300A is March 2 of the year after the calendar year covered by form. Information must be reported electronically through OSHA’s Injury tracking Application. This can be accessed from the ITA Launch Page. To learn more about OSHA’s occupational injury and illness data reporting requirements, including who, what, and how, start here:
Keeping records of serious work-related injuries and illnesses helps employers to understand hazards in their establishments and to act to reduce and eliminate those hazards. Because OSHA’s recordkeeping requirements can be complicated, however, OSHA offers general and detailed guidance on the requirements; provides a question and answer tool; and has published Letters of Interpretation to help employers keep accurate records.

Severe Injury Reports
OSHA collects information about every work-related fatality and every work-related amputation, loss of an eye, or hospitalization.The information collected includes information about the time and place of the event as well as a description of the event itself. These data allow OSHA to focus its efforts more effectively to prevent fatalities and serious work-related injuries and illnesses. Federal OSHA data are also available to employers, employees, and researchers to use to make workplaces safer and healthier. Interested in learning more? You can access these data here:
