Dear Sirs,
WOODLANDS NORTH
We regret to have to inform you that three of our daily-paid labourers are now in hospital suffering from suspected lead poisoning. Furthermore, two others who reported feeling unwell have been examined by the Company's Doctor.
We have recently been cleaning Woodlands North Tank No. 3 which has been in use for the storage of leaded aviation gasoline and as the people concerned were directly engaged on the cleaning work we must assume that their present condition is the result of working in the tank.
In order to give you a clear picture of the methods employed in undertaking the cleaning of the tank in question we give the following informations-
1. After the tank had been emptied of 100 Octane Aviation gasoline it was filled with water to over-flowing for the purpose of rendering it gas-free. The tank was then drained out com pletely but since slight traces of gasoline were detected it was again refilled to approximately halfway for the purpose of draining off the traces of gasoline through the main valve. After this the tank was completely drained.
2. On the 8th September the one manhole cover on the front end of the tank and which, as you are aware is located within the tank tunnel, was removed and the tank left open to gas-free until the iVth September.

Dear Sirs,
WOODLANDS NORTH
We regret to have to inform you that three of our daily-paid labourers are now in hospital suffering from suspected lead poisoning. Furthermore, two others who reported feeling unwell have been examined by the Company's Doctor.
We have recently been cleaning Woodlands North Tank No. 3 which has been in use for the storage of leaded aviation gasoline and as the people concerned were directly engaged on the cleaning work we must assume that their present condition is the result of working in the tank.
In order to give you a clear picture of the methods employed in undertaking the cleaning of the tank in question we give the following information:-
1. After the tank had been emptied of 100 Octane Aviation gasoline it was filled with water to over-flowing for the purpose of rendering it gas-free. The tank was then drained out com pletely but since slight traces of gasoline were detected it was again refilled to approximately halfway for the purpose of draining off the traces of gasoline through the main valve. After this the tank was completely drained.
2. On the 8th September the one manhole cover on the front end of the tank and which, as you are aware is located within the tank tunnel, was removed and the tank left open to gas-free until the l^fth September.
3. On the lMjh September Bennett together with a fitter and four labourers - all clad in overalls, rubber knee-boots and gloves (but without res pirators) entered the tank in order to lay a hose from the water line in the tunnel to the extreme end of the tank. We should like to add that our purpose in placing the hose at the extreme end of
the tank - which is 150 feet long - was that we
planned to pump water from the far end along the bottom in order to wash any sludge remaining back towards the manhole cover through which it was allowed to flow out along the tunnel into the drain and eventually into the sea. These men were in the tanks for about 5-10 minutes only.
4^ 1
- 2-
With the hose in place on the morning of the l*+th September water was pumped from the jetty at the rate of approximately 35 tons per hour and this flushing continued during working hours until the 18th by which time all sludge appeared to have been cleared and the water running back through the manhole was clean and, we assumed, sludge-free
5. Under the supervision of Bennett, five men clad in protective clothing (but without respirators) entered the tank on the 18th September for the purpose of hosing and sweeping. Here we wish to emphasise that the surfaces were kept running wet from two hoses during the whole period of cleaning. However at one period Khamis bin Mohomed, Ali bin Abu Bakar and Jaffar bin Suboh were found to have removed the overalls from their shoulders,,and were working with their bodies uncover#!^ ^xiiese' men worked approximately one hour in the tank with half-hourly intervals in the open.
6. Cleaning work continued from the 18th to 27th September with a break of four days, three whilst a tanker was discharging into an adjacent tank and one on "Hari Raya". During this period an internal inspection of the tank: was made by the Branch Engineer.
7. Having completed all cleaning work by the 27th September, Contractor Wong & Co. commenced work laying a concrete bottom to the tank, its purpose being to facilitate the draining of water after the receipt of cargoes of aviation spirit. On the 28th September a further internal inspection of the tank work was made by the Branch Engineer. Concreting work was completed on the 3rd October and at the time of writing no ill-effeets have
. been reported by the Contractor's \irorkmen.

any evidence of organic disease - advise continue present medicine - report in three days". This man appeared to be much better on 5th October but we allowed him to rest. However on the 6th October as he complained of occasional loss of the use of his arms he was sent for yet another exami nation this time by Dr. Frame, who recommended that he be admitted to hospital and the same evening he entered the Johore Bahru Hospital for observation.
Dr. Smith at the time he on the 2nd October told him to report for a further examination on the 5th October but on the morning of the 5th he reported for duty saying he was quite well. However since he was a suspect we insisted that he be re-examined by the Doctor. Once more the Doctor reported that the tests carried out were negative and he is apparently
alright. (Refer Enclosure10 1 for Doctor 1s Resort)
15. in addition to the four men already mentioned, Bennett and three other of our workmen were engaged on the cleaning and modification of this tank and since we wished to ensure that they were all free from the effects of possible lead absorption we arranged for the remainder to be medically examined and this is being done today, Saturday 7th October. Acting on the advice of Dr. Frame we have issued to the Depot Superintendent for distribution calcium lactate tablets which the men are taking three times a day, and we are also supplying them with a pint
of milk morning and afternoon as a precautionary me asure.

Absorption through the skin at this stage was con sidered to be unlikely as rubber gloves, rubber boots and overalls were used. Neither Bennett nor the fitter have suffered any ill-effects and both have been medically examined with negative
results.

17 lie also considered it reasonable to suppose that '* after having puraped approximately 1100 tons of
water along the bottom of this tank from the far end it would have been sludge-free before the actual cleaning work commenced and our supposition was qualified (to some extent) by the fact that the water flowing back from the tank was clean.
18. Having assumed the tank to be sludge-free the cleaning party equipped with brooms and two hoses entered the tank on 18th September and commenced hosing and sweeping. It is pointed out however that small quantities of sludge had become en trapped - along the bottom - in the angle of the tank ribs and this was swilled out with water.

Perhaps we should mention that we were unable to

and the Duty Medical Officer - -we were advised by
the Superintendent - knew nothing of the case.
The Branch Engineer therefore telephoned Dr. Frame
and it was arranged that in company 'tilth Mr. Dobree
the three would visit the hospital on Sunday, 8th
October for an interview with the Medical Officer-
