PHILOSOPHY - If we err, it will be ir* a safer direction rather than being more loose. UP I100098 A. CURRZirr (Effective July 7, 1972) 1) 3-hcur tine weighted average concentrations of asbestos fibers to wnich any employee r.ay be exposed shall not exceed 5 fibers, longer than 5 nicror.eters/CC of air. 2) Concentrations of 5 fibers, but not to exceed 10 fibers/CC permitted up to 15 minutes per hour not to exceed 5 hours per day. B. July 1, 1975 . #, 8-hour time weighted average not to exceed 2 fibers longer than 5 nicrometers/CC of air. C. MAXIMUM CONCENTRATION No employee shall be exposed (without protective eo.uipnent) at any time to concentration in excess of 10 fibers longer than 5 Eicroneters/CC of air. KCTCETORIUS A. EQUIPMENT - Ve have 6 air sampling devices on hand ready for use. These are personal monitoring devices which are worn on the lapel within the breathing zone cf the employees. TT B. PROCEDURES - We have a procedure worked up for taking samples',as well as a list of Jobs ro be sampled throughout the plants. C. ANALYSIS 0? SAMPLES - We plan to send samples taken to an outside vendor for analysis. We also plan to run an analysis in our lab,which will give us faster results and a check against those that are sent out. * DUP I 100100 actio:? it" a. e::hausesystehe B. ROPING OFF C. WARNING SIGNS D. MATERIAL E. WORK PRACTICES - control exposure We have Installed an exhaust and filter system on our oand saws, enclosed then in a separate room and provide exhaust from these rooms. We also have Installed two Torit downdraft work tables, wnich have their own exhaust and filter systems in the Insulation Shop. We plan to rope off areas where dust is being*created above the allowable limit. We plan to install warning signs at each Insulation Shop according to 0SR4 regulations and we have sample signs that we will identify roped off areas and other areas - where asbestos dust might be above allowable limit. Substitute materials are being sought to replace asbestos, but to date tr.ere is no good substitute. We do have a cement now that we are using that does not contain any asbestos. Scrap insulation is being disposed of at present in plastic bags to eliminate dust. General work prac tices will be changed threugh train ing with tne philosophy .that dust collection systems, good housekeeping, and good work practices can generally maintain dust concentrations at safe levels. When removing insulation from boxes, at present a corner is cut off the edge of the box and a vacuum hose is attached to pull off the fine parti cles of dust as the-Insulation is removed from the box. Waynesboro is experimenting with spray guns to wet insulation before removing, cutting, etc. We plan to experiment seme in the field on 3r.all insulating jobs tc establish if and where this method might be practical at Spruance. DUP I 100101 PROTECTIVE EQUIPMXT-T A. RESPIRATORS . - We provide our people with respirators at present, but do not require them to wear these except when cleaning out filters. We have ample respirators and the procedure fcr care and mainte nance of respiratory equipment, ana now in the process of developing a training program on the proper,use of this equipment. We have a list of Jobs that we feel respiratory . _ equipment will have to be worn. - ' These will be verified through sampling. B. SPECIAL CLOTHING ' When respirators are required, special clothing is to be provided. It was recommended in our meeting in Wilmington that the special clothing be provided to be of tne disposable type. Tyvek was men tioned as & candidate. We have sent some samples of different types of insulation we use to Glen White , at Centre Road at Wilmington to be used in testing Tyvek^ for its ability, not to pick up **besto* dust. Paper uniforms were also mentioned as a candidate. We don't AM *, MIWN Wj 1 a4 W* V AW w a ma w4 1 1 AW M aaa provide as yet, but we will provide special clothing anytime an employee is required to wear a respirator. Also when special clothing is prov ed a change room and separate lech are to be provided to prevent the DUP 1100102 PROBLEM. A PI'AS A. EXrlAUST SYSTEMS FOP HAND TOOLS To date no one has developed a satisfactory exhaust system forhand tools usedin the field such as, knives and saws. Weare looking at how we might use a vacuum cleaner to do the job. The wettinz method cay prove out to be the only way." B. SPECIAL CLOTHING Who other than Insulators should wear protective clothing 'is a problem we will be faced with. On line overhauls the decision as to whether we should have the insulating crew go in and strip the area before the pipefitters and millwrights go in to dismantle the equipment, or furnish everyone with protective clothing and let them al3 go in doing the Job wearing respirators. If we cannot get satisfactory disposable clothing, the problem of how we will handle the laundering to meet OSHA requirements has to be solved. C. LOCKERING We can provide extra lockers for the insulators in field maintenance, but this may become a problem in the areas and if we consider all the people that could work in an area being furnished special clothing and separate lockers, this could become a major problem*. Another problem area will be the changing of the habits of consuming of food, and smoking in the shop as well as in roped off areas in the field where insulation dust may not be in the air but is on the equipment.
