Cleanlnr, and Repairing of Tanker Compartments which have contained leaded gasoline.
Bear Mr, Paseo,
Thank you far your letter of 24th November in reference
to the above. 1 have read with great interest the exchange of cables
between Mr, K,8, Balsxllie and the Standard Oil Co. of H e w Jersey; also
the copy of the regulations covering "The cleaning, gas-freeing and inspecting of Cargo tanks of tank vessels" issued by the Standard Oil Company of Kew Jersey, under date of Juno 15th 1942,
Br. Kehoe, at the meeting held at Sfoell-Mex House on 15th October last, stated that he had not up to that time had the opportunity of discussing with the American Tanker operating OKg>aaies the question of special regulations for the cleaning and repairing of Tanker compartments which had contained leaded gasoline, but in view of the very comprehensive information which he had gained at the meeting, he would take the matter up with them immediately upon hie return to the United States.
This m y possibly explain why no specific reference is made
to any lead hazard in the regulations issued by the Standard Oil Co. of New Jersey
and also the reference in their cable to the avoidance of skin contact with leaded spirit. The regulations in question are, I think, an excellent example of those referred to in the opening paragraph of our draft regulations, i.o.,
.existing regulations for the avoidance of fire, explosion, and toxic hazards in handling gasoline, as enforced by Individual oil companies or other agencies."
I think we can say that the specific problems arising from
the large seals transportation of leaded gasoline by Tanker have c o m to light
earlier in this country than in the U.S.A. by reason of the questions raised here in regard to the carrying of edible oils, water and grain in such vessels.
In view of the potential hazards which, in our opinion, exist we believe that regulations along the lines of those already submitted to you in draft are essential. The only alterations which I wish to mate ere primarily ones of phraseology to bring the proposed regulations into line with those we *

have already agreed v?ith the oil eofflpanies hore for the cleening end repairing of shore tanks. I enclose twenty (20) copies of our revised draft.
Dr. Kehoe has, unfertunately, now left the country and whilst he stay be returning here for a few days on his w a y hack to the United States, this is doubtful. Both Sir* Foss att and myeslf would be available to attend a meeting at any time convenient to yourselves other than Tuoaday, tlovember 3or the morning of Friday, Deceabor 3rd.
As requested, 1 ea returning herewith the copy of the Standard Oil
Go. of K e Jersey regulations tfcieh you so kindly sent me. Very truly yours,
T. it. A. Sevan.

Regulations Schedule B .
-
1) A blower-type or positive-pressure full face-piece airline hose mask must be worn by any person who enters a compartment which has at any time contained leaded gasoline and which has not been thoroughly cleaned. This applies not only to cleaners, but to all others who may go into the compartment for any purpose.
2} Hoselines for air masks have a limited life and must be kept clean. If a
workman notices any odour such as gasoline while wearing his mask, he must leave the
compartment at once and find and remedy the cause.
-
3. All workmen must change into special clothing consisting of clean overalls, shirts, underwear (in cold weather) and socles; also heavy rubber or acid-proof gloves and rubber boots of good quality and in sound condition.
4. Clothing must be changed (and laundered) and a bath must be taken every day, either at the end of each day's work or when the job has been finished. If at any time the clothing gets soaked with sludge, the workman must bathe at once and put on clean clothes. At the end of each day, and after the job has heen completed, respirators, boots, gloves and tools must be thoroughly cleaned. Before taking any meals,the face and hands must always be washed, and clothing must be changed if inspection shows that it is badly contaminated.
5. Sludge or scale is dangerous to handle even after it has been taken out of the compartment. It should be kept wet and buried at once in a placevhere it will not be uncovered later.
PRECAUTIONS FOR REPAIRMEN
. Before welders or repairmen arc permitted to enter,the compartment should be
thoroughly cleaned. Such cleaning implies the removal of all scale which may be
dislodged from the inside surfaces during the course of repair operations. Unless this
procedure is adopted, repairmen will be required to follow the regulations specified
under Schedule B.
*
Attention is drawn to the possibility that dust, scale or sludge may remain on ledges or projections in the compartment, or may settle there during the course of the cleaning operations. It shall be the duty of the responsible officer in charge of cleaning to see that these sources of dust or vapour are removed, so as to prevent exposure during any subsequent operations in the compartment.
' Welding or other hot work should never be done until the compartment has been cleaned and all areas which may get hot are scraped down to clean metal. If after cleaning and owing to extraordinary circumstances, dust, hot fumes or gasoline vapours
fegenerated in a locaTised area within a compartment, an airline mask should bo worn.
