Smith reported that tho tost holes in tho duet work of their dust collecting system aro made by drilling a hole through the duet where a pipo coupling has bcon brazed to tho duct, when tho holes are not in uso they aro sealed with a pipe plug. This insures that all readings will be taken in the sane location at each teat. The members report that routino tests are conducted from one to four times a year in their plants. Tho cosrittee discussed the problem of dust being generated at the rub aprons on tko card condensers. This dust is not being collected in Most plants at tho prosent tir.o.

As with any other tool, respire.tors are designed for r.pocific purposes and exposures anl must he used accordingly. The United Staler Qureau ef iltncs is the ngoncy which establishes the standards and specifications for rcopirator dosirn and performance.

Distribution . ,. .............. ,.......................... Cn.' method' of distribution is to have tuo respirators identified for . ,i>ach nan.

A oocond tochnlquo is to arrange for daily or periodic pick-up ant; nolivery of respirators to a given distribution point, (forcr.-.cn's office, deportment store room). All rospJrators picked up after a period of uso aro cleaned and sanitised and rodistributod without rofcrcnco to the point of oorlier uso. *. r 6, Maintenance It is rocusaonded that msintenanco of respirators bo done at a control location by an authorised individual.
