About Us

Occupational Training & Supply, Inc.
Large enough to support you, Small enough to know you


OTS is an established training company. We provide the technical training necessary to comply with current environmental, health, and safety regulations. Founded in 1990, we saw the need to provide a more hands-on type of training than was offered by other providers. As our reputation has grown, so have our facilities and scope of training and services.

In 1996, OTS further expanded its services to the industry by initiating a supply division. We offer a complete line of environmental, health, and safety supplies and equipment. OTS can help you with all aspects of safety in your operations. Look to us as your complete safety resource.

We can provide you with all the tools necessary to do the right job, from proper training to the proper equipment and supplies! We offer a complete line of training, equipment and supplies in the fields of asbestos, lead, mold, hazardous materials, construction, restoration, confined space and OSHA safety compliance.


OTS is a Woman Business Enterprise (WBE), certified in the City of Chicago and State of Illinois.
