These code numbers represent camota used. The writer was inferoed that none of tm essente used in the ccapounriing of brake blocks contained banaeno. 22&t!yl ethyl katene(KH2 ) is tbs sclvsnt used in placa of benaeas.

ilaoaable aixtursa of the vapor in air are practically intolerable to rasa because of the odor and oye and nose irritation#
ASBESTOS:
The long fiber! tye asbestos is used and the inhalation of asbestos dash over a period of years produces a lung disease k<o*a as "wtoestosia" There ia no
known cure for this disease. Its action is aialLar to that of silioosia. Various States, including Ohio, have set a laariacn allowable concentration of dust fres
asbestos as not to exceed 5 nil!ion particles of dust per cubio foot of air.
1 would like to suggest that 2 rdllidn, or evoa lees, oo established hero ther" is the possibility cf uaployees inhaling asbestos dust*
U.D BLACK:
There 1 a nossdhiliiy that only lead black is used in the cosseandiug ef the brake
2-
block* snd
as pcsjdarud lead In ssy fora Is used. 1 as not certain IT this
is the ease, If only lead black is used then no lead haaard would be produced
since lead bleak' is graphite ad graphite Is carbon
I aa wondering why this company aalntalns periodic ariaary analyses for lead on the eaployess working in this department if no lead compound* ere used.

this type duet ifcile nc-fc considered texio, will produce a lung condition which simulates silicosis on x-rayplates. Xt is called "sidereale" end is not dis abling, The dust coate the lungs a brownish red color and, although not toxic, should not be inhaled.

Brass is a copper-Eino alloy of varying composition. It usually contains soma lead or tin, , sometimes both, with small percentages of other material. Ea of the Division of Safety and Hygiene do not feel that the small percentage of lead in the brass would ever be s factor in producing lead poisoning. Our chief com plaint from brass grinding operations is the discoloration of the skin experienced by the employees. This operation predaces a greenish color.

This is & registered proprietary anas for silicon carbide. Silicon carbide does not contain any free silica end is not considered toxic. It la an extremely hard substance. Silicon carbide does produce irritation of the nose and throat.

The inhalation of iron (hist, dust from brass chips and carborundum dust nay pro duea a bronchitis or a canal inflammation on certain individuals.

No toxicity information is available on this material.
The ruthio material is first mixed with the USX in an open vessel, No exhaust is provided for this mixing operation. I recommend that an exhaust bo provided for this unit because of the dermatitis which might be produced from any duBt generated.
There la a fire basard in connection with the use of VEX, It is therefore recom mended that the motor on the agitator be of a vapor-proof type, that is be non explosive and that it be correctly grounded.
After the plastic material is mixed with the USX, it is placed In a dry mixer and the asbestos, lead, brass chips, dictalite, iron dust and carborundum, etc. rre added. This mixer is enclosed and a seal is maintained around the opening on the door at the top. A slight vacuum is produced therein. There is a condenser unit coniB cted to the mixers so that the solvent ME* cun be retained. Since those two mixers are all enclosed, no dust would escape and no exhaust system is deemed necessary.
After the material is thoroughly mixed, it is removed and allowed to dry, after which it 1b placed in a Cumberland grinder. An employee ground soaa of this dxy material in the grinder on the date of this visit. Extrwraely high dust concen trations escaped into the atmosphere during the operation. It is, therefore, recommended that this Cumberland grinder be adequately exhausted.

If the cants are high, each a over 5Billion partid e a of dust per cubic fo o t
of a ir , then exhaust e&oulcl be provided for the new machine*
In the weighing out o f various aatarialo fo r the batch, a respirator should su ffice as protectir a equipment for the operator* Because o f the few moments spent each day in th is weighing, elaborate exhaust systems are not p ractical. However, the use of a gans s&rk is inadequate protection from d ist and only an approved Bureau of Bines respirator should be fhruiifoed
After p elle tin g , the brake block is than placed under heat and pressure and no dust is generated at th is operation.
The only other dust produced is at a v ertica l surface grinder which is used to
remove rough edges fra * the block; Since th is grinder fracture* the dust into
extremely small micronic p a rticle *, i t is recomcnded that th is grinder be ex
hausted*
Tha chief dust haaards appear to be non-toxic in nature with the exception of the asbestos and any lead, if used. However, these dust, which are from the any compounds used, enn very easily produce troublesome problems. All dnata are compensable providing proof, can be s^owa by nodical authorities that they, the dusts, ar a factor* It should, therefore, bshcove management to exhaust each dust producer to an outside collector*

Tb brass chips in the barrels are laaarssd,- barrel and all, in a trichloro ethylene degreasing tank. Siaployeea oowplaia of the fusee from the trichloro
ethylene. The writer did not find any holes, in the bottoms of the barrels which would allow the trichloroethylene to escape. It is therefore recemended that all odor of trichloroethylene be removed from the barrel of chips before it ia brought into the brake block area. It may be necessary to install a specially exhausted cabinet in which to plrco the barrel until all odor ia ramrod*
Investigation disclosed that employee re required to notch chips of asbestos board with a circular saw. They also must sand several layers cf these boards on a spin dle type sunder. Tha dust generated on both these operations is excessive and constitutes a health bastard. It is, therefore, recemended that the saw and sander be exhausted and that the duct from euch a system be collected in an outside (list
collector.
Asbestine type talc, air floated, is used to dust platens. Since the toxicity of the talc is questionable, X suggest that it be replaced '.th that of a dusting powder which has been proved to be non-toxic.
Bbila walking through fee kitchen of a cafeteria in the - -aft Division, it was noted that a meat grinder was not adequately guarded, the distance from the worm to the throat of the hopper was approximately 8 inches. Bo wooden meat gtoaper is used. A nan grinding the meat uses hia hand to press the meat into the hopper. The possibility of the lose of a hand or all fingers is extremely great. It is, therefore, recomnended that a safety type hopper be obtained for the grinding of all meat in all Goodyear-operated kitchens. The A & P Tea Company, in conjunction with The Hobart Manufacturing Company, has designed a special g_:xrd for seat grinders.
There ie ono 'ore hazard which seems to have been overlooked. A paint spray booth located in the area where small white porcelain cabinets are being constructed is in a deplorabls condition. Used paint rags were on tiie floor and a fcsavy coating of paint was adhering to the inside walls of the booth. It is, therefore, recom mended that this booth be cleaned and kept cleanj that all paint rags be immersed in a meted container one-third full of water. The use of water in this container will prevent spontaneous combustion. At the present time this booth is a definite firo hazard.
