It was in 1938 that Illinois first turned its attention to this new material and a pilot operation started in 1942 01 501 1349 What Has Illinois Dons to Investigate the Health Aspects of Kaylo It has always been a cardinal policy of the Company that the Safety and Health of its employees and those who handle and use their products be properly protected Illinois made three types of investigations A. examinations including chest rays and annually thereafter Since the very beginning of the pilot plant operation no employee has shown any evidence of lung damage dermatitiosr other physical ailments traceable to the handling of Kaylo Arrangements were made with the New Jersey State Health and Labor Departments Workman's Compensation Insurance Carrier and the Industrial Hygiene Section of Illinois for special recommeann d d rea comtmeindo atn ios ns Both Forkoman Compensation claims and group insurance claims were studied to datoraine if exposure was a factor in any sickness None of these investigations and studies have show any commection between working with Kaylo and the physical well being of the employee Illinois has followed closely the experience of people in the field who cut fit and handle Kayle materials Mo complaints have been received from any user reflecting any health or physical impairment on the part of the people handling Kaylo material Good reports have been received from them com- paring the working with and handling of Kaylo to other materials D. Arrangements were made with The Saranac Laboratory to condunt experiments on the health aspect of Kaylo dust This work started in 1945 and continued until completion in 1952. It explortehde nature of lung reaction in animals who breathed for 81 1350 D. Cont'd Cont'd The factory shipped dust to the Laboratory taken from the dust collectors as deposited from the normal manufacturing operation ^ room was constru8 c ^ t 8 e ^ d 8. In one corner of the room a hopper was erected and filled with Kaylo dust By meaofnaspaddle that rotated inside the hopper a cloud of dust was generated This was mintained eight hours per day five days per week and for four hours on Saturdays The room was operated for more than five years About 450 animals were used in the experiment and some of them lived continuously in the dust room for as long as three years At regular inter aniv maa ls l wes re killed and the lung tiamus examined to determine the nature and extent of dust reaction The tissues ware also analysed to estimate the amount of Kaylo dust retained in the lungs of animals exposed for definite pariods of time The conclusions of the research work done with Kaylo dust on animals were 1 That there is no possibility of developing silicosis 2 That dan is g no e dangr er of developing Asbestosis with normal handling of Kaylo products Test showed that continued exposure to concentrated Kaylo dust inhaled over a long period of time was capable of producing in animals increased tissue growth typical of Asbestosis The reaction was milder than what pure Asbestos chust would produce 3 That the dust has a slightly unfavorable influence upon a tuberculous infection after extensive exposure over a long peroi f o tid me 01 501 1351 General Conclusions Expeir n i theefan ctc orie es and field and research findings have proven that normal handling of Kaylo products is safe a from health standpoint The usual precautionary measures taken for any product containing Asbestos are needed in a continued exposure to heavily concentrated Raylo dust 01 501 1352
