On August 1, 2017, the Department of Labor's Mine Safety and Health Administration ("MSHA") issued to MOR PPM, Inc. ("PPM"), an indirect subsidiary of EMCOR Group, Inc., an imminent danger order (the "Order") under Section 107(a) of the Federal Mine Safety and Health Act of 1977 at the Smart Sand, Inc. sand mine, in Monroe County, Wisconsin.  The Order was issued when PPM employees were observed working adjacent to what an MSHA inspector alleged were unprotected ventilation openings in the floor of a Rotex Screen which the inspector deemed to be tripping hazards.  There were no injuries and PPM took immediate corrective action, and the Order was terminated by MSHA immediately after it was issued. PPM disagrees that an imminent danger existed and is considering its legal options to contest the Order, including but not limited to further informal review with MSHA and litigation.     SIGNATURES   Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this Report to be signed on its behalf by the undersigned hereunto duly authorized.           EMCOR GROUP, INC.                         Date: August 3, 2017   By: /s/ R.
