Specifications which the United States Radium Corporation will put into
effect to eliminate the hazards connected with radium dial painting, so
far S.B "Radium Poisoning" is concerned.
1 - Rigid and continuous inspection of all processes involving the use of
radium by a qualified officer.
2 - Painting by hand will be done by
a method which will eliminate the
contamination of the mouth with radium. No pointing of the brushes with
the lips will be permitted.
3 - Wherever possible, styluses or pens will be used as a substitute for brushes,
which will eliminate any temptation to point the brush with the lips.
4 - Cloths will be furnished for pointing brushes and for wiping styluses or pens.
For wiping pens or styluses, cloths will be kept moist with a suitable solvent.
5 - Paint containers will be approximately 1/2" deep, and be so placed in a holder
that retaining them in the hand is unnecessary.
6 - The mixing of dry paint with liquid ingredients will be conducted under a
hood provided with suitable exhaust ventilation, to prevent the escape of
dust or emanation into the workroom atmosphere. Only small quantities of
thepaint will be mixed at one time. The exact quantity will have to be gov-
erned by the type of work which is being done.
7 - All utensils will be cleaned moist. The discarded material will be placed
in refuse cans which will be promptly removed from the workroom.
8 - Moist cloths only will be used for removing paint from surfaces, and in
recovering radio-active material from old or rejected stock.
9 - All stocks of radium material will be stored in containers shielded by lead
and kept as distant as possible from the workers.
10 - The rooms in which radium painting processes are carried out will be separated
from those used for other purposes.
11 - The rooms shall be/constructed so that they may be thoroughly and readily cleaned
by moist methods. They will have the usual daily cleaning and a thorough
scrubbing once weekly.
12 - Ample space will be allowed for each worker.
13.- Adequate illumination, free from glare, will be provided.
14 - Convenient washing facilities will be provided, with arrangements for mixing
hot and cold water. Paper towels and nail brushes will be provided.
15 - Only neat, careful persons will be allowed to do this type of work.
16 - Clean smocks will be provided weekly.
17 - Operators will be required to keep their hands and work-places scrupulously
clean at all times.
18 - Eating during working hours, and the presence of eating utensils or articles
of food in the workroom will be probibited.
19 - The workers will be required to thoroughly cleanse their hands and finger
nails before eating and at the close of work each day.
20 - Adequate general ventilation will be provided.
21 - The painting by hand will be done beneath a sheet of plate glass of suf-
ficient size to cover all the radio-active material, and so placed that
the face of the worker is not less than 14" from the work.
22 - Inspectors of finished work will be provided with exhaust ventilation of
sufficient quantity to secure an air movement of 100 to 200 linear
feet per minute at the surface of the work being inspected; such movement
being away from the inspector.
23 - Dusting and transfer press work will be eliminated so far as possible, but
when performed, adequately safeguarded.
24 - Periodic examinations, at least semi-annually, including electroscopic tests
(gamma ray and radon) & Blood examinations of the employees will be made
by Dr. F.B. Flinn, Department of Industrial Hygiene, College of Physicians
andSurgeons, Columbia University: N.Y.City. The results of these examinations
will be communicated to the employees.
25 - The employees will at all times be fully apprised of the possible hazards
connected with this work and the necessary precautions to avoid these hazards.
26 - Adequate facilities, separated and apart from the work shop, shall be pro-
vided where the girls may eat their lunch under pleasant surroundings, and
where they may go for periods of rest when necessary.
