RECE.veD aug 1 a 1986 18 August 1986 TO: C. C. Neely 511/2000 RECEIVED r. 1986 CCN SUBJECT: ASBESTOS VS NON-ASBESTOS Issue: The higher cost of non-asbestos gasketing Is less than the extra handling cost of asbestos. To properly dispose of asbestos gasketing It should be wetted for removal, bagged after removal, and taken to a disposal site for landfill. The following calculations show how much time at a base labor rate of $15/hour could be spent on these extra steps to reach breakeven on a cost only basis. Also a calculation Is made on a 535/hour sold service rate basis. Gasketing: 2" - 150* Gasket Asbestos Non-asbestos Grafoil 10* 16* *1.00 Non-asbestos: f!6* - 10(1 f60 Minutes! [*15/Hour 1 [ Hour ] - 0.24 minutes 0*35 - 0.10 minutes 6rafo11: m.OO- 10*1 f60 Minutes! [ *15/Hour j [ Hour J - 3.6 minutes 0*35 - 1.5 minutes In other words. In the worst case If more than 3.6 minutes were required to wet, bag, and dispose of an asbestos gasket It would be more expensive. UCC 015700 Packlno: S/Lb. Chanaes/Year S/Yr.1 Asbestos 10 5 50 Grafoll 200 1-2 (1) Assume 1 lb. of packing Is used per change. 300 --^ - Consider a very conservative case. Assume the total time to change packing Is 1 hour and each change requires 1 lb. of packing. Asbestos: [(110/Lb.)(1 Lb./Change) + (115/Hr.)(l Hr./Change)] x 5 Changes/Year - S125/Yr. . 8 135/Hr. - 1350/Yr. 6rafo11: [(1200/Lb.)(1 Lb ./Change) + (115/Hr.)(l Hr./Change)] x 1.5 Changes/Year - 1320/Yr. 9 135/Hr. - 1225/Yr. Breakeven: 9 115/Hr. 1320 - (110 115 X ) 5 X - 2.56 Hours 9 135/Hr. 1350 - (110 + 135 X ) 5 X - 1.56 Hours Breakeven does not occur until 2.56 hours per packing change at the 115/Hr. rate, or 1.56 hours at the 135/hour rate. Either Is easy to Imagine when all factors are Included. Some are the following: o Receive the job assignment o Inspect the job for condition and correct packing o Get the necessary packing (may require ordering material) o Get the tools for the Job o Repack the valve (frequently leaking must be stopped before work can begin) o Clean up the job o Put away materials and tools o Seek the next job LEC:ka 6267k Larry E.
