raSTHtreSMT SHOP - MERCURY SXP03UBS3
Tty f 7n n J
Jlercury was dispensed from the instrument shop storeroom by
drawing off weighed amounts from the bottom of a steel reservoir having
a oapaoity of about 3 flaaka (153 lbs*). This dispensing apparatus was
essentially two steel reservoirs; the upper one, whioh was connected to
the lower, and larger one, b/ a short length of pipe containing a shut*
off valve, actually serving ae a funnel into whioh a flask of morcury
could be poured* The open top of the upper reservoir, Was colored with
a plexlglas lid* The thole apparatus was mounted on ah angle-iron frame
whioh rested on a rough oonorste floor*
.
Keroury 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 flasks were sent to the recovery yard as scrap, although a few were reported to be used as drip pans in the instrument shops*
Examination of the dispenser and the immediate area showed evidenoe 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 oonld not be as certained, although the latter is more likely the ease. The area was roportodly oleaned once a week although from appearances, the cleaning was not thorough*
In addition to the handling of mercuryaa described above,
specially purified mercury in five-pound ceramic bottles was issued frost
time' to time,
-
3h the instrument shop itself, mercury was stored in a 76poun& flask on the edre of one of the work benches for .use as shop supply, Uercury was obtained from the flask through a valve tapped into the side of the flask aoout a half-Inoh from the bottom* Here again# there was evidenoe of careless handling, as shown by a considerable number of droplets of mercury on the rough oonorste floor direotly beneath the valve on the flask as well as on the benoh top. The instrument shop was reported to be cleaned dally.
While there was less evidenoe of mercury spillage at the work benches and mounts where instruments were repaired, then was observed in instrument shops in certain other of our refineries, a considerable amount of mercury was noticed on the calibration stand,
Xnstrumsnts in the field that need repairs were drained of mer cury at tbo site, brought into the shop where they were steam oleaned and repaired. After repairs were oompleted, mercury- from the shop supply was added and the Instrument calibrated, After calibration, the aereury was removed from the instrument end returned to the shop supply and the instru ment returned to the unit and the original mercury replaced.
While the large else of the storeroom and the instrument shop itself would seem to preclude the possibility of nsro-ry poisoning under normal conditions, there is a possibility that hesardoua concentrations

of moroury vapor and duat night occur because of tha inadequate bousekeeping with respect to mercury, Horoury la a cumulative poison, insidious
in nature. Zta vapor pressure la auoh that, at room temperature an at-

Recoomendatiotaai
1. Mercury should ba frwdled ao aa to avOld spillages. In the event that they do occur In aplta of precautions, all spilled mercury should ba oleaned up promptly* Good housekeeping should ba maintained at all times.
8* The mercury dispenser in tha atorerOoa should ba placed in a
non-amalgamating metal or other impervious tray with no erovloaa in which
mercury can oolloct. XT the bottom of this tray sloped somewhat to one
comer, removal of any mercury from the tray would be simplified* If "
water is kept in tha tray, volatilisation of spilled meroury will ba
greatly reduced.
.
3* The mercury reservoir in the instrument shop should be mounted over a non-amalgamating metal or other impervious trey of sufficient else so that any meroury leaking through the valve will fall into the tray, the dispenser should not be any higher than la absolutely necessary to minimize the splashing of any meroury escaping from the valve.

WAX LABORATORY - KSPC7RY SXP033B53 The block point tost for paraffin wax being used involves the
use of considerable Amounts of mercury* Two pieces of paper# impregnated with the wax to be tested were plaoad in cellophane envelopes# mounted In Ire frames add partly submerged In a vertical position in beakers con taining mercury* The mercury was used to exert a uniform pressure against the wax-impregnated paper* Stoppers# each containing a vent hole And a thermometer# were then inserted in toe beakers and the beakers placed in oil baths hasted to 90# 95# 100# 105# and 110F* Aftsr the mercury reached the desired tomperature# 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 obtainsd by pulling apart the two stripe of paper*
The oil bathe 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 wbloh reportedly recirculated about 90 per cent of the workroom air*
The floor of the wax laboratory was of small white hexagonal ceramic tiles* The work table had a metal top without a lodge* Consid erable amounts of mercury were seen on the table top and to a looser extent between the floor tllee*
This test method waa about ready for publication# but it was reported that releaee had been held up pending the addition of a section pointing out that a mercury hasard warn associated with the test* to this connection# a block teet which does not require the use of mereury merits consideration* In this test the envelopes containing the wax-impregnated strips are placed on an aluminum plate having a built-in temperature gradient control# covered with a pieee 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 tbs mercury vapor concentration in the teatrooa ranged from 0*12 - 0*16 mg. of moreury per cubic meter of air when only two mercury beakers were being used in the lower tomperature ranges* The air immediately above the beaker contained 0*80 - 1*10 mg* The air around the hands of tha operator after removing strips from the envelopes showed 0*50 - 0*60 mg. per cubic meter* The maximum allowable oonoentration of mercury vapor la 0.1 mg* per cubic meter of air* These concentrations indicate that rigorous control of the mercury hasard la advisable* Recommendations:
1* All operations should be done in a hood having adjustable louvers at the top and bottom of the baok side* The air velocity at the face of the hood should be at lsast 100 feet per minute* The air exhausted from the hood should be discharged to the outside* In this oonneotlon# the proposed use of tubes containing water seals on the meroury containers

wore well awar* of the precautions for the aaf handling of mereurjr and
were doing a 'reheritable Job of keeping these rooms meroury-free in spite
of the poor conditions of the rooms* Flowers of sulfur were sprinkled
on the floor fron time to time in an attempt to control mercury vaporiza

used from time to time to reclaim mercery* It was planned to replace this
still by a smaller sited one whloh will be located in an exhaust ventil
ated hood* A linoleum table top on the Ho* 2 gaa analyse* unit in room
1 was very much in need of repair*
^
The throe rooms which comprise the gas analyses laboratory have
adequate roceral ventilation throughout most of the year and this fact,
coupled with the oars used by the employee in handling mercury#: would
appear to be adequate oontrol of any hazard* The use of sulfur'to elimi
nate the vaporization of mercury is' not always as effective as ooimaonly
exposed* It is doubted that under existing conditions the use of sulfur
contributes much to the oontrol measures*

DRUM WBf.DINO - G. AND C. BUILDING
Leaky drums which war* detected during the cleaning and re
conditioning of drums on the fourth floor of tha C. and 0* building wan
repaired by means of acetylene- welding torches. The weldors 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 fumes on health* Most of the drums were made of steel,
but a certain number were galvanized. It was the welding of galvanized
drums particularly that gave rise to the complaints of nose and throat
irritation. One employe in particular claimed that he had developed metal
fume fever every time he welded galvanized 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 galvanized 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 tbe 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 ainc oxide fume which in its freshly formed state produces a condition commonly termed zinc chills or metal fume fever. The aymptoma of thla metal fume fever are chills and fever and some degree of nausea. The acute chill is generally preeeded by a feeling of dryness in the throat, cough, and generally cornea on a few hours after exposure, and it Is a transitory condition. Zinc la not a poison in the true sense of the word and complete recovery occurs within a few days. A transitory immunity may develop and continue as long as the exposure to the fume continues, but may disappear within a few days after exposure terminates, such as over a weekend.
Beoommendatlonsi
.
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. per 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 galvanised drums should be done in this booth, Tha same booth could be used for welding of all drums if desired.

A burette, uaad for diapenaing TEL fluid, waa connected by means of a glass U-tuba to a amall natal reservoir on a aholf naar the top oX an exhaust-ventilated hood. Tha approved method for refilling thia reser voir la to dlaoonneet tha glasa buratta and t$tube, place tha raaarvoir on tha bottom of tha hood and pour tha TSL fluid into tha raaarvoir froa tha atooic bottla. Tha hood waa auffiolantly largo to panelt all of thia to ba dona lnalda it. However, thia procedure waa not followed.
Xnatead, a aaall hole had been punched In tha top of tha hood dlreotly a-ovo tha filling hole of tha raaarvoir so that a funnel could ba inserted and tha TEL fluid poured into tha reservoir from the outside of the hood. Tha top of the hood waa about 6 feat above tha floor, which would make it neoessary to stand on soma object or reach very high while pouring tha TSL fluid. Thia method presented an unnecessary exposure to TSL vapors and increased the chances of accidentally spilling tha fluid.
Two other conditions, minor in nature, should be remedied. One was the absence of a supply of kerosine at tha hood for removing any TSL that mi^ht gat on the skin. Kerosine waa said to ba aval labia around the laboratory, but speedy removal of TEL from tha skin is essential, and valuable time could ba lost in looking for a keroalne bottla "somewhere in tha laboratory*. Tha othar waa tha storage of tha rubber glove a in a desk drawer a short distance away where they might not be Immediately accessible.
Re commendations t
1. The practice of filling the TEL reservoirs from outslda the hoods
should ba prohibited. All handling of the TSL fluid aha.Id be done inside
the hoods.
.'
2. A supply of kerosine for the sols purpose of removing TSL from
the skin should be kept at tha sick next to the hood.
