About Us

CHESS occupational safety and health experts assist companies with workplace safety, health, and environmental issues. Employers, especially those who do not have sufficient safety expertise in-house, find our services comprehensive and cost-efficient. Although we specialize in providing comprehensive safety, health and environmental services to small businesses, we work with companies of all sizes, from two employees to over 200,000, and on projects of all sizes, from providing a one hour safety training session to helping with all aspects of a client’s safety/health/environmental program.


CHESS safety professionals can help you understand and comply with OSHA and regulatory compliance standards, EPA regulations, fire code requirements, and more. We believe that every client has unique needs – no cookie cutter safety programs.

We will work with you to develop your occupational safety and health program from the ground up, building upon what you have already established, assist you with safety training where appropriate, or consult with a specific safety, health, or environmental concern. You’ll get customized, flexible services with the safety experts from CHESS.

Carol Keyes and Janet Keyes, the two sisters who own CHESS, began the company in 1993. The safety sisters knew that small and medium businesses, where safety was just one of many hats worn by the owner, the human resources director, or the production supervisor, needed help with safety programs and OSHA compliance. Janet’s background and training as an industrial hygienist put emphasis on preventing workplace injuries and illnesses. Carol’s background in workers’ compensation and her experience running her own small business gave her insight into the need of business owners for cost-effective safety and health consulting.

The CHESS team of occupational health and safety professionals serves clients in the Twin Cities of Minneapolis and St. Paul, Minnesota, Milwaukee, Wisconsin, and other areas.
