Directorate of Technical Support and
The Directorate of Technical Support and Emergency Management (DTSEM) includes offices located in the National Office along with the Salt Lake and Cincinnati Technical Centers. DTSEM provides special expertise in a number of areas to ensure that OSHA's capabilities are state-of-the-art with regard to occupational safety and health. These areas include:
- industrial hygiene,
- safety engineering,
- occupational medicine and nursing,
- sample analysis and equipment calibration and repair,
- emergency preparedness and response,
- statistical analysis, and
- technical data services.
Experts in these areas are used by the Agency to supplement other program staff by providing specialized technical expertise and advice. The wide range of expertise and services available in DTSEM results in our being involved in every major program area of the Agency, as well as in compliance assistance and outreach activities. Implementation of our Directorate's programs provides support, service, and solutions for the rest of OSHA.

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:
Winter weather presents hazards from slippery roads/surfaces, snow removal, strong winds, and environmental cold. Employers must prevent illnesses, injuries, or fatalities, by controlling these hazards in workplaces impacted by winter weather. OSHA and National Oceanic and Atmospheric Administration (NOAA) are working together on a public education effort aimed at improving the way people prepare for and respond to winter weather. This page is designed to help businesses and their workers prepare for winter weather, and to provide information about hazards that workers may face during and after winter storms.
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. To explore these pages and more, start here:
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:
Occupational Chemical Database
OSHA's simplified resource for occupational chemical sampling information. This new resource provides essential information to help CSHO’s collect chemical samples in the field for analysis at the Salt Lake Technical Center Industrial Hygiene Chemistry Laboratory. Basic chemical information, sampling methods and sampling media selection information are provided in the Occupational Chemical Database, making it a vital resource for collection of defensible air, bulk, and wipe samples.
