The whole apparatus was mounted on ah angle-iron frame whloh rocted on a rough oonorete floor* . Mercury was dispensed through a valve at the bottom of the lower reservoir into an aluminum pan resting on a "kitchen-type* scale* About two hundred pounds of mercury was dispensed monthly* gapty flacks were sent to the recovery yard as scrap, although a few were reported to be used aa drip pans in the instrument shops* Examination of the dispenser and the Immediate area showed evldenoe of careless handling of mercury. Small globules were noticed all over the dispenser and the floor* Whether these droplets -were* the result of a few large spills or from many small spills oould not be as certained, although the latter la more likely the case* The area waa reportodl7 cleaned once a week although from appearances, the cleaning waa not thorough* In addition to the handling of serouryas described above, specially purified mercury in five-pound ceramic bottles was issued from time' to time* - In the instrument chop itself, mercury ** stored In a 76-pound flask on the edre of one of the work benches for use as shop supply* Mercury was obtained from the flask through a valve tapped into the side of the flask a*out a half-inoh from the bottosu Here again, there was evidence of carelesa handling, aa shown by a considerable number of droplets of mercury on the rough concrete floor direotly beneath the valve on the flask aa well aa on the bench top* The instrument ahop was reported to be cleaned daily* While there waa less evidence of mercury spillage at the work benches and mounts where instruments were repaired, than waa observed in instrument shops in certain other of our refineries, a considerable amount of mercury was noticed on the calibration stand* Instrument# in the field that need repairs were drained of mer cury at tho site, brought into the shop where they were steam cleaned and repaired* After repairs were completed, mercury from the Shop supply was added and the instrument calibrated* After calibration, the mercery was removed from the instrument and returned to the shop supply and the instru ment returned to the unit and the original meroury replaced* While tho large else of the storeroom and the instrument shop Itself would seem to preolud# the possibility of msro-ry poisoning under normal conditions, there is a possibility that hasardous concentrations WA-TEX 003748 P?D* HSO.

HTG. SUHVST PAW, April, 1S52 - A2D "6" WAt LABORATORY - XSPC7RY SXPQ3JHS3 The block point tt for paraffin wax being used involve# the use of considerable amounts of -mercury. Two piece# of paper, impregnated with the wax to bo toatod were'placed in cellophane envelope#, Counted in wire frames add partly submerged in a vertical position in beakers con taining mercury. The meroory was used to exert a uniform pressure against the wax-impregnated paper. Stoppers, eaoh containing a vent hole and a thermometer, were then inserted in tne beakers and the beakers placed in oil batha heated to 90, 95, 100, 103, and 110P. After the mercury reached the desired temperature, the beakers were removed from the oil baths, allowed to oool to 70? and the paper strips removed. Information on the properties of the wax was obtainad by pulling apart tha two strips .. of paper. The oil baths were kept on a table top in the open in a rather small room which was kept at a temperature of 70P by means of a small air-conditioning unit whleh reportedly recirculated about 90 per cent of the workroom air. ' The floor of the wax laboratory wae of small white hexagonal caraaio tiles. The work table had a metal top without a ledge. Consid erable amounts of mercury were seen on the table top and to a lesser extent between the floor tiles. This test method was about ready for publication, but it was reported that release had been held up pending the addition of a section pointing out that a mercury hasard warn associated with the test, m this connection, a block test whleh does not require the use of mercury merits consideration. In this test the envelopes oontainlog tha wax-impregnated strips are placed on an aluminum plate having a built-in tamperature gradient oontrol, covered with a piece of sponge rubber to insure uniform pressure on the strips which is provided by a weight placed on the sponge rubber pad. While no mercury determinations were made in the wax laboratory, confidential Information from another laboratory showed that the mercury vapor concentration in the testroca ranged from 0.12 - 0.16 mg. of aoreury per cubic taster of air when only two meroury beakers were being ustd in the lower temperature ranges. The air Immediately above the beaker contained 0.80 - 1.10 mg. The air around the hands of the operator after removing strips from the envelopes showed 0.50 - 0.60 mg. per oubio meter. The maximum allowable oonosntration of mercury vapor is 0.1 mg. per ouble meter of air. These concentrations Indicate that rigorous control of the mercury hasard la advisable. Re commendations: 1. All operations should be done in a hood having adjustable louvers at the top and bottom of the back aids. The air velocity at the face of the hood should be at least 100 feet per minute. The air exhausted from the hood should be discharged to the outside. In this connection, the proposed use of 9-tubes containing water seals on the mercury containers WA-TEX 003750 UTO. nxa. suhvsjT PAW, April, 1952 - ASD -7- would not bo aucoaaary.

Hon-amalgamatlug motol oontalnora ahould bo used instead of rlaaa beakora to minimise spillage of aeroury duo to oontainor breakage. 3. Tho work table and hood ahould bo provided with a ledge to prevent widespread scattering of any spilled mercury. All oracka and orevicea In which mercury might colloct ahould be fillod. 4. Opening of tho eollopbano envelopes ahould be done over a tray. A photographic developing tray with a pouring apout to facilitate return of mercury to a container la auytgeatod. An oxpanded natal sheet in tho tray night be uaed aa a working surface. 5. ' The mercury containers should be kept covered as ouch as possible and bo stored in tho hood. Keeping the containers In trays when not in us# would .help to localise any spills. 6. Good housekeeping should bo maintained at all times. Dry sweeping of tho floor should bo prohibited. - 7. Sating or storage of food in the blook teat room should not bo permitted. 8. Uaed envelopes, teat strips and any wiping rags should be disposed of in a closed top waste oontainor. Such refuse should be destroyed by burning. ' 9. Good personal cleanliness on the part of the eoployea should be practiced. % UX 1 5u06 WA-TEX 003751 - rm. hts. 3:;nvsr PAW, April, 1S52 - -3- MASS 3PSCTK0*KTia LAB * fl&RCUHY ,2X?CS',R53 A small Amount of coroury wa* usad In laraltng bulbs for tha infm^rod gas analysta a^uipmant.

BUILDIRQ Leaky drums which were detected during the cleaning and re conditioning of drums on tho fourth floor of tho C. and 0* building wen repaired by mean* of acetylene- welding torches. The welders hAd made complaints that the fumes produced during these welding operations were irritating to the nose and throat and had expressed apprehension as to the effects of these umes on health. Most of the drums were made of steel, but a certain number were galvanised. It was the welding of galvanized drum* particularly that gave rise to the complaints of nose and throat irritation. One employe in particular claimed that he bad developed metal fume fever every time he welded galvanised drums, and for this reason, he was not assigned to galvanized welding. # Two small hoods, one used when welding leaky bungs and one used when welding bottom, top and side seams of galvanised drums, were an inef fective means of control of the zinc fumes produced during welding. Improper design of the hoods, coupled with the inadequate air flow partly due to the presence of at least 6 right angle turns In the duct, made these hoods ineffective. - It was observed that the fumes escaping from the bunga of steel drums were slightly irritating. The presence of small amounts of residual cleaning solutions in the seams might account for some of the irritating qualities of these fumes. Welding of galvanized metal produces considerable quantities of sine oxide fume which in its freshly formed state produces a condition commonly termed sine chills or metal fume fever. The symptoms of this metal fume fever are chills and fever and some degree of nausea. The acute chill is generally preoeded by a feeling of dryness in the throat, cough, and generally comes on a few hours after exposure, end it is a transitory condition. Zinc is not a poison in the true sense of the word and oomplete recovery occurs within a few days. A transitory imxBunlty may develop end continue as long as the exposure to the fume eontinuee, but may disappear within a few days after exposure terminates, such as over a weekend. Recommendationsi . 1. The two ineffective hoods used for the welding of galvanized drums should be replaced by a welding booth having a face velocity of at least 150 ft. psr minute. Such a.booth 4 ft. wide and 6 1/2 ft. high with a depth to suit of 6 ft. or less would require 3,900 cubic feet of air flow per minute. A drawing of such a proposed booth is attached with this repor 2. All welding of galvanized drums should be 4one in this booth. The some booth could be used for welding of all drums If dssired.

Tha red lead was stored in paper bags in one corner;of the shop. Quite a fow bags had aome powdered red lead on the outside and there was oonaidarablo lead spilled on the floor evidently froa broken bags. The housekeeping in this seotion was inadequate, considering the toxist nature of lead. In mixing paint, the necessary number of bags of red lead were dumped into a large ball mill by an employe Who, according to reports, did not wear a respirator. The empty bags were put into drum* with open tops for disposal by burning. The belisf that no lead besard existed because the paint mixing Job wae done intermittently and not necessarily by the * tame person eaoh time should not be accepted, as a reason for not observing precautions. '- Reoommondatlonsi - 1. All red lead in the storage area of the palntahop should be cleaned up and the area kept clean thereafter. 2. All epille of red lead powder because of torn bags should be cleaned up promptly. . 3. All oleaning should be done bj vacuum methods if practical. If such oleaning can be. done only by dry sweeping, the employe should be required to wear an approved type dust respirator and no other persons should be in the vioinlty during the sweeping process unless wearing res* pirators. ' 4. Employes should be required to wear approved type respirators then handling bags of red lead and while dumping them into the ball mill. 5. Soptied red lead bags should be handled so as to avoid dissemina tion of dust both In the paint shop and during eventual disposal. They should be kept In covered containers.

Instead, a small hols had been punched in tha top of the hood directly acova tha filling hole of the raaarvoir so that a funnel could ba inserted and the TEE fluid poured into the reservoir from the outside of the hood. The top of the hood was about 6 fact above tha floor, which would make it naoassary to stand on soma object or raaoh very high while pouring the TEL fluid. This method presented an unnecessary exposure to TBL vapors and inoreased the chances of accidentally spilling the fluid. Two other conditions, minor in nature, should be remedied. One was the absence of a supply of kerosine et the hood for removing any TSL that mi,-ht get on the skin. Kerosine was said to be available around the laboratory, but speedy removal of TEL from tha skin is essential, and valuable time could be lost in looking for a kerosine bottle *soapwhsre in the laboratory*, Tha other was the storage of the rubber gloves in a desk drawer a short distance sway where they might not be Immediately accessible. Be ooaaendatlone i X, The practice of filling the TEL reservoirs from outside the hoods should be prohibited. All handling of the TSL fluid should be done inside the hoods. .' 2.
