In spile oi the utmost care, detects in workmanship and materials do occur in any inamifactured article. These defects must I- mimd before the article leaves the fac tory, therefore, it is necessary to minutely inspect each article, diligently searching tor and rejecting defective merchandise. These inspectors, veil trained, are paid a bonus tor rinding defects; liovever, as an added precaution, their workmanship in turn is checked by product quality inspectors to a-stirc accuracy and eriicicncy.

Quality control work in any manufacturing industry involves two major saietv func tions. The first consideration is the safety of the employee, to see that the operator is performing Ids job with the maximum degree of.saiety to himself, that the mate rials lie works with, his tools or machines have no apparent functional defects that may be hazardous to safety. The second consideration, safeguarding titc safety of the consumer by seeing that each operation is being performed correctly, being con stantly alert to insure the observance of specifications in order that uniformly high quality, safe merchandise is produced.
Dusts in the Rubber Industry
By P. A. D A V IS , M .D., FA.JP.HJk.
Goodyear Tire & Rubber Co., Akron, 0 .
Ilusts may be da-sined in two main groups:
1. Harmful: 2. N'ot harmful or nuisance.
When we think of tins classification, we undoubtedly think of sonic type of pneumoiioeoiiiosis. However, I believe we must not base our conception of dusts on this basis, but assume that all dusts are detri mental to the human system as a whole when the concentrations are high enough. Whether the disability is due to a toxic condition or to a mechanical one, of course, depends entirely upon the nature of the dust. The conditions usually reierred to as living of mechanical origin fall under that condition known as pncumonoconiosis with its various suit-divisions o f :
Silicosis. Side rosis. A ntlim co sis Asbesto.*!. Chalcosis. Cltalicosis.
The method of contracting pucumonoconiosis is by inhalation of the dust; however, all dusts do not cause pr.eutnouoooiiioiis. The higher the silica content of a dust the greater tile possibility of developing a fibro sis and the higher the percentage oi crystal content the greater the irritation. The diagnosis of the type of pncimioitocoiiiosis is based upon the following:
1. Past history and occupation. 2. Physical examination. 3. Clinical examination of .-putum. 4. X-rays of lungs.
Since wc have been stud Cue the lungs of industrial workers by x-rays, there has de veloped an entity which mould he .term the ''Industrial Lung." This condition, believe, should not bcTcrmcd a pncur.tono
coniosis because it reaches a certain ^ S t `
does not progress any further and
several months to a year improves.

'The other conditions caused by iiiltaiatious , coiubie dusts, insoluble, but free from
jlica. and metallic dusts have to be discussed under a specific condition; for example, lead poisoning is icrv frequently caused by the ohalaticm of lead dust; and many nose and throat irritations arc caused hy inhalation of insoluble dusts whose action is strictly mechanical. " ' therefore may also classify dusts as: I. Pncumonoconiotic; 2. X'onpneumonoconiotic.
Some of the principal dusts or materials used in industry which fall under these classifications are as follows;
pneumonoconiotic:
I. Silicosis (sandstone, slate flour, fuller's earth. Stoughton earth, iitfusiottal earth, rotten stone, any other clay with more than /: of Wc silica, ground glass).
I Siderosis--iron ores, iron oxides 'r.at), iron sulphides (naL).
1 Antliracosis--coal and carbon dusts. 4. Asbcstosis--powdered asbestos, asbestos

The following procedure will be helpful in solving your problem of dust.
1. Make repealed dust counts of llic working area at various levels.
2. Obtain some of llic dust and send it lu ti.e laboratory for complete analysis in cluding the determination of free SiOs.
I. Examine the workers, x-rays of the dies: for those working in pneumonoeoniotic dust;.
4. Check the ventilation and increase it In r.ilnce non-liazardiuis atmospheres.

7. .-tudy the particular dusts from the mechanical and chemical nature and if the dice: - arc unknown, resort to animal experinieir.aiion.
N it dusts arc toxic and harmful consider the : vssibilitv of a substitution for a nonliarnful substance.
9. Examine and x-m v all employees who are ring placed on fobs where there is a dust hazard. They should be examined peri' c.callv.

The dust counts uu toxic dusts must be kept at a minimum, and much lower than that for silicotic dusts. In silicotic dusts die particles of 10 micron size or larger are of very little concent, but with toxic dusts the

Ii you find any evidence o i trouble it is letter to correct the cause than to transfer hi employee elsewhere, for this often causes dissatisfaction and suspicion. AH mch conditions can be controlled if there is cooperation lietwcen llic medical, engineernj and managing departments, in most cates at present all conditions caused hv hiit are compensable, so it behooves the enployer co correct his working conditions to a point at which there are no hazards.
Conclusion
h is impiodhie ;o give a detailed descript'"it oi all ilsv mi-is used in the rubber
industry, for the silicotic dusts alone would require a volume io do chem justice, but I warn yon co remember that there arc just as many serious conditions w-liich may de velop from the. inhalacin of various toxic dusts.
rtese conditions arc often more serious than pneuinoiioconiosis and develop much taster and in a shorter period of time. For installer, a icrsoii may develop a lead poison ing in two months from inhalation of lead compounds and it might take five to ten years lor a silicosis to develop in the same environment of silica dust.
There are on the market today many fine and etiicient protective devices such as chemical protective masks, dust respiraiors, positive pressure masks, clothing and gloves which if used will give good results.
Instruction to the employees by the super vision in regard to their personal habits, their instruction concerning the type of dust they are exposed to. and tvhy they have to use the protective appliances, will reduce the mssiliility of any trouble to a minimum.
All lalioratory week must lx: done by a technician who has been trained in the vari ous toxicological Ini-oratory techniques and the interpretations must lie made in con junction with the past history of the in dividual. May I say' in conclusion that it is much more profitable to correct a dusty operation than to declare it a hazard.
