U.S. Chemical Safety Board Chairman Rafael Moure-Eraso commended the International Association of Plumbing and Mechanical Officers for issuing tentative interim amendments to the Uniform Plumbing and Mechanical Codes to prohibit purging fuel gas piping into industrial, large commercial, and large multifamily buildings. IAPMO is the third trade organization to revise its codes to incorporate new purging safety requirements as a result of recommendations issued by the CSB, which conducted an investigation of a catastrophic natural gas explosion at the ConAgra Slim Jim manufacturing facility in Garner, NC, in June 2009.
