JUSTUS FISHER <br />3 i 06 Nordi 31 st Street <br />Tacoma, Washington 98407-6405 Repon 2339-01 <br />April 23. 2002 <br />To: Charlcs Souder, General Manager <br />TC Systcros, Inc. <br />1028 1V Marinc Vicw Dricr. <br />Gvcrett, WA 98201 <br />Rc: Report 2339-01 <br />At your rcyucst I inspcctcd thc dip tank li��c �vith you, n4onday April 1�. "?00_'. Thc <br />purposc of the inspection was to cvaluate the structural implications of some failed <br />sidewall memlxrs. 'i'he Tanks :ve stainless stecl with mild stecl framcs. approximately 60 <br />Pt long x 3 Ft wide x 12 �T deep, :md arc grouped in sets of three or four tanks side by <br />side. A stcel framework s�pports thc tanks approximately 2 Fl� abcwc the iloor and a <br />catwalk system around and between ihe tanks approximately 10 �T above the floor. <br />1'hc tank ���alls are supported by �" channels. The channels have failed lxt�veen three <br />taiiks in onc set, and the tank walls have de(lected acainst cach other. The outer walls of <br />thc sct are straight. I understand }•ou ha��e tound no significunt deterioration of the outer <br />ch� nnc�s or ather frame mcmbers. We did not obscn�e ::ny other signs of distress. <br />In my opinion thc deterioratcd framc mcmlxrs bet�vccn the tanks do not represent an <br />immediatc problem �rovided that the fluid le��els in the adjacent tanks are maintuww .�� <br />appro�imatcly the same IeveL I recommend that the frame be repa'ved as soon as <br />practicable :uid that �vhcn the tanks are drained, to drain them simultancously lo avoid <br />sienilicant diflcrential �luid Ic��cls. I recommend that tlm intcrior framc members on thc <br />othcr tanks � thoroughly exanuned when the repa'v work is done. Stainless steel may be <br />uscd in licu of lhc mild slccl lo providc longer lifc in the repa'ved strec+�.+re iCdesircd. <br />Providing a stainless steel Oashing ovcr the tank edges to prcvent spill3ge between the <br />tanks, as ��ou suggested, should help reducc the corrosi�n rate on dic frame members. <br />Prcparcd by <br />Gric V.
