Asbestos Workers Local 24 Pension Fund Defined Benefit Plan is a multi-employer defined benefit union pension fund based in Columbia, Maryland. Established in 1958, the plan covers both asbestos workers, pursuant to collective bargaining agreements between the International Association of Heat and Frost Insulators and Asbestos Workers Local 24, Washington, D.C. and employers, and certain other employees who are not covered by such collective bargaining agreements. The assets are managed by a six-member Board of Trustees.
