Description of Plant
The above company owned, by
i s a small chemical company
employing, four men. Since i t s beginnings in December 19h$> they have been en
gaged in the manufacture of small lo ts of specii. chemicals among which have
been organic mercurials (for a n tisep tics and fungicides) Cresol derivatives
phenyl esters e t c .. The plant occupies a former p o lice barracks of fa ir quality
construction, situated about f i f t y fe e t from Highway 8, in the v illa g e of Beacon
F a lls, Cormecticut (near Waterbury). The inside working space i s about f i f t y
by one hundred twenty-five fe e t with attached garage per rough sketch below.
Floors of building of pine - concrete in garage. There is a dwelling (Dr.
Bowles') above the main structure.

2 . Character of Exposure
.
The follow ing m aterials were involved and are lis t e d in the probaole order of ' importance:
a. Mercury dieth yl and i t s degradation products b. Mercuric, and mercurous mercury alkyl s a lt s .( A c., CO3, e t c .) T
c. Mercurous and mercuric s a lts including Ac. C0 Oxides d. Degradation products of TEL. e . Benzol f . Mercury g. Other compounds 'which may r e su lt from reactions in the follow ing procedure:
(The presence of gummy o ily mass at the end of the reaction suggests the presence of polymerization products of alkyl mercury compounds).
About May 19h&> one case of 12 ca'Sfe o f pure TEL was acquired from r-thyl Corp. to
be used as an alkyl carrier in the reaction for preparation of ethyimercuric acetate in syntaxes of 3-Me, 6-a lk y l, ethyimercuric, thiosodiumbenzoate. In the preparation of th is a n tise p tic , one gm mol TEL and l . i gm mol HgAc are reacted in anhydrous benzene. The f i r s t operation w^s begun on 3 August I 9I46. forking out doors, UOOml TEL were transferred fro-; the can to a beaker, gloves ana apron only being worn. There was no detectable odor or sp illa g e . The TEL was taken into the laboratory and added to 6L anhydrous benzene (under hood) and reaction started Q by addition of Hg Ac. The reaction went poorly at low reflu x temperature of 80 C and c r y sta lliz a tio n did not occur in four hours. Mixture was then filte r e d on laboratory table near open window and allowed to stand 36 hrs t i l l $ August, at which time i t was noted that the f i lt r a t e had turned salmon-red. The f ilt r a t e and ppt were then mixed and the benzene d is t ille d o ff (at 200mm Hg) and the r e s i due taken up in absolute EtOH (6L) and refluxed vigorously for 6 hours. Cn cool ing, a small y ie ld of needles was gotten. The mixture was then u is t ille d to h a lf
(3L) volume when evidence of decomposition appeared in the shape of free mercury;
mixture was then f ilt e r e d hot and again concentrated by d is t illa t io n to one-fourth origin al volume ( l i) There was further decomposition with more free mercury appearing. Mixture was then filte r e d and cooled with separation of a pasty, o ily mass with the characteriss of a super-cooled s o lid . Above procedure was carried out during -3th and 6th August. On 7th August, o ily mass was subjected to numerous t e s t s for id en tity - procedures occupying entire day - work stopping in evening because of pain from burns of hands of operators.

kViednesday 7 August l$GO-1930 hrs.
Sources of exposure were:
a. Vapors of reaction mixture - e sp e c ia lly during decanting and
filtr a tio n
b. Skin contact with m aterial that had penetrated (perhaps) or been
carried into gloves
(1) D istribution and d iscrete character o f 'le sio n s suggests
carriage of material into gloves.
c. Dusts from sp illa g e on floors and equipment

d. Vapors and ousts from open Buchner funnels, beakers, ana tne evident
gross deposits on outer surfaces of glassware from stoppage.
e . Owing to the course of the efflu en t vapors from the hooa, there was
secondary exposure of the occupants of the apartment on the upper
story. This was lim ited to Hrs.
(including 3/9 of a ch ild ),
two infants ages 20 and 8 months resp ectiv ely , ana to Dr. Bodies
when 'a t home'. Feed-back into the main laboratory space was also
possible - th is point was, however, not checked. The p ollu tio n of
the general air of the residence was seriou s, however, since during
our. v i s i t there was pronounced ouor at various time in most of the
rooms near the side of the hood and in the corridor.
In the main laboratory space, the odors were quite strong and per s is te n t - th eir pattern of d istrib u tio n is indicated by the hatching in the sketch of the structure. (Cross-hatching = very strong) Oaors were not lik e those of TIL or degradation products, but strongly suggestive of alkyl mercury s a lts - no sneezing was produced. Must iness predominated.
3 Protective Measures
a. Technique of handling was poor and housekeeping worse. Material was
l e f t standing open on Chem desk #2 and s p i ll s of mixture on flo o rs and equipment not wiped or cleansed. .Dirty tow els, aprons and clothing were responsible for the odor in the washroom. b. Gloves ana aprons were in good condition but dirty c . Ko respirators are provided d. hashing f a c i l i t i e s (noted above)
U. Recommendations
a. Removal of residence from apartment and immediate cleanup of a l l product - to be buried.
b. Purchase, rather than, manufacture* of t: e interm ediate, eth yl mercury
acetate or:
c. Isolation of operation - a separate building with concrete floor, ventilation
and change room with shower.
d. Redesign of chemical hood with b affle and extension of vent pipe. Hood to be
cleansed statim.
e. Provision of cleansing m aterial - kerosene, sulphury1 chloride, bleach e tc .
f . Coating o f floors
g. Treatment of wastes in sump - with proper trapping and d ilu tio n .
h . .Provision of baths for treatment of glassware prior to washing.
i . Construction of showers and separate lockers for clean and d irty clothing. .
j . Procedure re impervious gloves
.
k. Canister masks in general laboratory - a ir lin e and canister in new building.
l . Sampling control of a ir .
.
m. Routine medical check.

PI See jo in t h istory of exposure. General symptoms began nito of 7 August with insomnia, c h ills and weakness and have p ersisted with s lig h t increase in
sev er ity . Cutaneous lesio n s began with severe burning of fin g ers, n ite of 7 August, causing stoppage of work. This was followed by deep pain in 1*8 hrs when a w hite, cooked appearance of skin of terminal phalanges, both hands 'was noted. I n it ia lly applied heat, then soaium bicarbonate for 3 hrs, then eth yl alcohol, th a d ieth yl ether, then potassium iodide solu tion and f in a lly ice, water soaks which have been continued sin ce. The insomnia is attributed to the pain which has been continuous. Since 8 August, there has been poly
uria and frequency - q 2h day and n it e . Appetite has been fa ir in past week
- no nervousness, bad dreams, .weight lo s s , e tc . No fever, or sweats 'with c h i l l s . There were stabbing pains over spleen at times in past week.
HI Three years,*.7 months medicine, PhD in chemistry, has done organic synthesis since age 25 with a l l types exposure. V/as poisoned by phenyl bromide in 1921*
- mainly pulmonary symptoms. No unusual exposure to any se rie s - has done
considerable work with organometallic compounds.

PI See jo in t h istory of exposure. Has had no general symptoms and has slep t vrell except for n ite of 7 August when was kept awake by pain from burns. Skin lesio n s started with intense pain in hands-and fingers which lasted for t h ir ty -s ix hours only. Twelve h urs after onset, a few small v e sic le s appeared on hands - these were opened, leaving raw fle sh beneath - most have e p ith e lia liz e d or crusted over.
LOCAL EXAMINATION
.
There are several 1 x 2cm opened blebs and numerous small (few inn) lesio n s on skin of both hands. A few are beep - most su p erficia l and healing w ell . with minimal areas of reaction .
On right forearm are several su p e rfic ia l reddened areas ( l x 3cm) with no gross destruction of skin or bleb formation. These suggest bromine or acid burns rather than le sio n s from m etallic s a lt s .
RECOMMENDATION
None - Samples blood and urine taken.
