Materials Headline ."athoda This aattar was brought ur for discussion relative to loadiag trucks fror ground level. Methods discussed ware* (a) fork lift trucks, sad (b) alaetric hoists, aad (e) hydraulic lifts. Advantages aad disadvantages of all three ware discussed. Most eoAfaAies have fork lift trucks, but, ia soae cases, they aay be ia use elsewhere at the tioe they are needed for loading a truck, alec, trie hoists are' adequate for iadoor use but aot practical for out* doors. Hydraulic lifts require a permanent installation and lack tb< flexibility ef a oobile unit. twt ayes for Post Collectors The relative oerits of bags aade froo cotton, Nyloa and ocron earn up for discussion, *a oost cases cot to b.gs are used. Sowe roaraaies have experimented with Nylon aas . <h Dacroa bags. The concensus was that the cotton bags were cute efficient aad cave a satisfactory service life.

The aext rhase, consisting of analysing the data, is mrofressiag. In addition* it is their intention to analyse trece eoetarinaata, to determine whether they are fresent and, if so, stii: active.

Nsre aad sort publicity is being gives to the health hararda ia working with asbestos. The latest, a clipping fro the National Observer of 2*%66, writtea by Jobs Henderson, H.O., discussed aooe syvmtoss of asbeotosis sad stated that the incidence of asbestosis is risiag tad that 30 years froa how it would be autt hieber. The article stated that 'doctors are systiMed by the arpearaace of s rare tissue tuaor, oesothelioaa, which is fouad iaeresaiagly ia asbestosis vietias*1. The iaeressiog aurher of these articles, sonareat 3 y being writtei for Personal publicity reasons, is disturbing to tiio industry and points up t&e seed for an ippsrtisl survey such as is being aide by the U.S. Oepsrtaent of Health* Bdueatioa d Welfare.

Using the B&L Dust Counter in the deecribed manner and inasmuch as the Implnger aeema to have beoome obsolete ( when the Membrane Filter ia used in conjunction with the D&L Duat Counter) it la not neoeaaary to develop a method for correlating duat counts obtained by the two instruments. Membrane Filter iiothod: Mr. C.D. Sheokler reported that the Impinger will moat likely no longer be used and that the membrane Filter Method ia going to be the aooepted method for evaluating asbestos dust. At the present time 12 fibers per oo, 5 microns plus, are considered to be the equivalent to 2 HPPCF ae reportod by rir.J.Dynoh, U.S.P.H.Service. Cleaning Procedures; Various methods for cleaning production equipment and rooms were disoussad. A member of the comnittee reported on the use of the Abington System for poriodic cleaning operations. Other member companies are using compressed air about twice a year for the removal of dust from pipes, rafters, ceilings, walls, etc. It appeare to be most important that in this area major efforts are made to improve our mothoda and preferably prsvont any excessive accumulation of dust. Dust Prevention in Blending and Carding: The oorsaittee members exchanged ideas in regards to dust abatement in the blending and carding operation, ^iclosed blending lines, use of plaatio bajjs for mixes, enclosed automatic card food, lap system and other devices were discussed.
