Tools that Sound Like Firearms and Explosives to be Used on Building 38​

​Beginning Monday, December 4 and continuing periodically through May 1, 2024, renovation work on the interior of Building 38 on the 1st floor and mezzanine will include explosive powder-actuated tools (EPATs) to setting anchors for metal stud framing.

When in operation, EPATs can sound like a gunshot, firearm or explosive discharging. Please do not be alarmed or confused if you work in or near Building 31 and hear this noise. Use of EPATs is a common practice in building construction. 

If you work in or near these buildings, please ensure your colleagues are aware so no one is unnecessarily alarmed. 

​Thank you for your understanding and cooperation as NIH continues with this important renovation of Building 38. For questions regarding this message, please contact the Office of Research Facilities (ORF) project officer, Josh Olson, at or 301-456-4062.​
