Westerman advised he had been.in centsct stith a previously employed a ' The alleger provide information that at' heat numbers had been applied to hangers after 7 ()

installation. Westerman advised that RIV would be referring this matter to 01 DIV for investigation. Subsequently, H. G.

He stated that M" post applied heat numbers" to pipe hangers (safety 79 and non-safety YeTated, seismic and non-seismic). The " materials were put up in a hurry, like a coal fired plant" and quantity was considered over quali,ty.

The quality control inspectors "wouldn't buy hangers" without heat numbers, so

. the craft found "the quickest way to sell a hanger was to put on a heat

. number." The craft would go to an. identical hanger erected before the hanger without the heat number, copy down the numbers and then stamp the numbers on the hangers without numbers. This information was also copied onto the " bill -

of materials." Field fabricated hangers were the principal hangers without heat numbers and traceability. Hangers. coming from the' fabrication shop had the heat number:s stamped on tftei.r componints'in the fabrication shop. The heat numbers we're usually stamped, sometimes "vibroetched," on field fabricated hangers. Shop fabrication hangers were never "vibroetched," only metal stamps were used in the shop. His foreman told him that should he ever be caught stamping the numbers on hangert. without heat numbers he was to say he was only making the numbers deeper.
