SMOHIT’s Mission

The Sheet Metal Occupational Health Institute Trust (SMOHIT) was founded in 1986 to address the impact of decades-long asbestos exposure on those working in the sheet metal industry. While screenings and research on asbestos and other hazardous materials continue to be the cornerstone of SMOHIT’s efforts, our expanding mission now includes being the sheet metal industry’s leading resource for health and safety products and services. Our mission is to provide industry-leading health and safety solutions to minimize occupational illnesses and injuries for sheet metal craftsmen.

We serve more than 216,000 members of the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART) and 4,500 members of the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA).


By way of introduction, my name is Randall A. Krocka and I’m looking forward to serving you in my new position as SMOHIT Administrator. My many years working in the sheet metal industry have given me a strong belief in the importance of health and safety:

• Member of the unionized Sheet Metal Workers for over 33 years
• Graduate of Wisconsin Menomonee Falls East High school 1978
• Graduate of Sheet Metal Workers five year apprenticeship program
• Worked in residential, architectural, commercial and industrial shops
• Served as Union Trustee for Local #18 Wisconsin
• Served as Local #18 Financial Secretary/Treasurer/Business Representative Since 2003

One of the most important things that we can do as Union Sheet Metal Workers is to ensure the safety of ourselves and those around us. It will be my job to make sure that you have the tools and information to make that happen. We will also be ramping up our asbestos screening program and addressing the health and nutrition aspects of dealing with preventable diseases. I am eager to work with you as you utilize SMOHIT as a valuable resource for your health and safety needs.

My door is always open. Feel free to call me with questions, suggestions and concerns at 703-739-7130 ext 3 or drop me a line at rkrocka@smohit.org.
