Artifi cial illumination is furnished by lseandoseont oloctrie lights equipped with reflectors. KA1TX PROCESSES Products aanufaetured in this plant involving tho use of asbestos arcs brake lining, brake blocks, and clutch facings. Three types of brake lining are made. These are woven asbestos doth, dry process lining, and eat process lining. made from Ths asbestos cloth is sods outside of this plant. The cloth is treated with rubber, cut into strips and folded to the slse desired. The fold ing is dens in Sepsrtasnt 3$ on aaehine #1513* This lining is cut to length in Department 8 en aaehine #1382. The dry process lining is aads from a mixtur > of asbestos, rubbsr, rssln, lithargs and cotton. Tho mixture is aads vp in Deportment 53T in a rotary sixer. Canadian asbestos is used. Ths asbestos as received is put through a hasiermlll and than througi a picker and over a shake screen. The other materials are kept la eontalnere. After the Mixture is eoaplstod. It is taken to Department 53* The mixture is voighed end pressed Into gboato in a heated press. Severd of thsss shoots are heated la a press for a given time. Tha sheets are then out into strips to tho desired width on a planer. Tha strips are ground to tho desired thlekaass in Gardner -3- surfaeo griadors. Thsy are then out to length aad foraod to o given radius la heated prtu. Solos sro drlllod la tho liaise s a goaf drill machine. The ads oro ehoafared oa abrasive wheels.

Lead la a cumulative poison and, with a fee exceptions. Industrial lead poisoning la usually a chronic condition caused by tho Inhalation or in gestion of smell amounts of soluble load over long periods of time* This prooes of poisoning may go on slowly for a long period without manifesting any of tho characteristic acute symptoms. Lead inhaled, however, is far Mrs rapidly and surely toxic thnn lead ingested, sinea It roaches the blood stream more directly and comparatively little is ollmlnatod unnbsorbed. Them is llttla agreement in tho estimates made by various authori ties on the minimum amount of lend which can cause poisoning if taken Into tho ' body. For practical guldanca, however, it can be assuaod that from 1 to 2 taken in daily ever a period of months or years may cause poisoning. A number of factors also entor into tho estimation of tho amount of sir bmsthsd by a man at aetivo work during tho worklag day. Tan cubic maters of air la a -16- tan hour day ii M titlMtt which nr; probably m on tho ssfs oldo for tha average workann.
