W. WEI PITTSBURGH OFFICE ROOM 5027 WPH 1985 JANUARY 28 RE: EXPERIMENTAL BERYLLIUM CONTROL VACUUM SYSTEM Attached, you will find a sketch and photographs to clarify the layout and to make our experiment more understandable. A steel vacuum ring is placed between the furnace top and the A-622 fluxing unit. The ring is connected by a flexsteel hose to an air operated vacuum cleaner system. This system consists of a Hako-Minuteman model X-702 cleaner unit equipped with a H.E.P.A. filter. Certification and filter data from the filter supplier are also enclosed. The use of the vacuum cleaner unit was only to test the feasability of the reducing beryllium levels using the vacuum ring. The ring could just as easily be piped to a station ary collector type filter. After our continuous testing, we hope to prove that tnis system will be effective in controlling beryllium levels for everyone in the foundry area.

Final (H.E.P.A.) absolute filter rated at 99.97% efficiency at .3 microns. g DUAL AIR SYSTEM Air brought into main filtering system is expelled into one compartment; air for cooling the motor Is conducted by a special series of intake fans around and through the motor housing and ex pelled ihto another compartment. This prevents any trace of moisture from entering the motor to cause shorting out. M EXCLUSIVE MOTOR COOLING AIR H.E.P.A. FILTERING For critical "white room" application, even car bon partidos from the motors brush es are trapped and prevented from contaminating the room air. A special recirculation system assures that all motor cooling air is exhausted thru the H.E.P.A. filter preventing deposi tion of these particles on sensitive electronic assemblies and compon ents. M POSITIVE WATER LEVEL CONTROL automatically shuts off the motor vacuum air flow when water reaches a pre-determined level in the tank,, preventing water from reaching th motor when the X-100 is used wet pick-up. K* QUIET OPERATION Special sounddeadening motor insulation and mounting pads isolate and reduce motor noise, making the X-100 whisper quiet to prevent disturbing workers or hospital patient;. 5a RUST AND CORROSION RESISTANT CONSTRUCTION Wherever possible, aluminum and aluminum alloy is used for critical components to ensure maximum resistance to the action of water, chemicals, and cleaning solvents. m QUICK, EASY UNIT CLEANING Large inside Primary Filter bag which traps everything but microscopic particles, is easily removed and replaced. Two snap type latches hold motor hous ing and cover securoty on tank. Spe cial gasket material provides air-tight seal between tank and cover to en sure maximum vacuum performance.

KONKOSKI - 204 1984 March 08 RE: SAMPLING RESULTS - INGOT PLANT BLDGS. 221 & 222 On 1984 January 10 and 11, air sampling was conducted to evaluate the exposure to total particulates, copper, and lead, while working near the ceiling of the Ingot Plant. The air samples were taken while two electricians repaired 436 crane and two other electricians worked above #30 complex. The results of the air sampling indicates that the exposure to total particulates, copper and lead are within safe limits (Table I). The wearing of respiratory protective equipment, while working near the ceiling, is not required at this time. However, circumstances may arise when the use of respirators may be necessary, i.e. when trace levels of chlorine are detected, or when performing dust generating activities, the appropriate respirator should be worn. If I can be of any additional assistance, please call. S. M. ANDERSON SMA: vag Attachment xc: M. J. Elder, M.B. - 22 E. E. Rumberger - Pittsburgh - 6 / P. T. Woerz Info. Copy to: R. L.
