Compiled by Albert H. Fay. INTRODUCTION. This paper, the fifth report of the Bureau of Mines, on accidents at metallurgical works, shows both fatal and nonfatal accidents at smelters and at ore-dressing plants. The figures for smelting plants include copper, lead, zinc, and quicksilver smelters, as well as refin- eries. Iron blast-furnaces are not included in the figures given herein. The ore-dressing plants represent concentrating plants for copper, lead, and zinc ores, stamp mills, cyanide plants, iron-ore washers, flotation mills, sampling works, etc. The total number of men reported employed in the metallurgical works, both smelters and ore-dressing plants, was 61,708, as compared with 68,487 in 1917, 66,194 in 1916, 49,891 in 1915, and 43,007 in 1914. The number of fatalities reported at metallurgical plants was 94, 35 at ore-dressing plants, 42 at smelters, and 17 at auxiliary works, including shops, yards, etc. The number of nonfatal injuries re- ported at ore-dressing plants was 3,142, at smelters 6,743, and at auxiliary works 2,808. The fatality and injury rates based on 300-day workers for 1918, compared with previous years, are given in Table 1. Table 1.-Summary of labor and accidents at metallurgical plants Men employed.

ACKNOWLEDGMENTS. The data presented in this paper were voluntarily supplied by the officials and managers of the metallurgical companies at the request of the Bureau of Mines, there being no law compelling the companies to render reports. Grateful acknowledgment is made of the hearty cooperation of the many officials who have answered the inquiries, and suggestions are invited as to manner in which the annual report of accidents at metallurgical plants may be improved so as to best serve the industry. Data for California and Colorado, respectively, were furnished by the Industrial Accident Commission and the State commissioner of mines. Statistics for South Dakota were furnished by Otto Ellerman, State mine inspector, and for Nevada by the Industrial Accident Commission. For assistance in the compilation of the various tables the author is indebted to W. W. Adams and Miss Mary Bringhurst. The percentage of accidents due to any one cause is given in Table 7. In the ore-dressing plants machinery was responsible for 40 per cent of all fatalities and 18.17 per cent of all injuries. Similar figures for smelting plants are much smaller for the reason that more machinery is used in ore-dressing plants than at smelters and the men are usually in closer contact with the machinery, as, for example, at jigs, tables, stamps, rolls, and crushers. There are many revolving shafts, a large number of which have projecting keys, moving belts, wheels, and cams within the reach of the operator. The machinery at smelting plants is usually confined to the power house, where the blowers, engines, and dynamos are placed, and to overhead cranes, almost all of which are entirely out of the reach of the regular smelter employees. A percentage of 17.14 of the fatalities at ore-dressing plants were due to falls of persons, whereas at the smelters the fatalities due to falls of persons represented 9.52 per cent of the total. Fatalities due to electricity represented 7.14 per cent at smelters and 8.57 per cent at ore-dressing* pl ants. Haulage systems caused 30.96 per cent of the fatalities at smelting plants and 14.29 per cent at ore-dressing plants. Of the nonfatal injuries at ore-dressing plants 5.58 per cent were due to haulage, whereas at smelters 9.58 per cent were due to that cause. At smelting plants burns from hot metal, slag, etc., claimed 9.52 per cent of the fatalities and 19.13 per cent of the nonfatal injuries. The tables call attention to the principal causes of accidents at these works and should serve as guides for the safety engineer to show where it will be possible for him to work most efficiently and to accomplish the best results. CAUSES OF ACCIDENTS. ACCIDENTS AT METALLURGICAL WORKS DURING 1918. 7 Although the figures are representative of the metallurgical indus- try, they are not absolutely complete. They do, however, cover more than 90 per cent of the industry. The reports received from the operating companies are rendered voluntarily at the request of the bureau, but there are always a few companies that do not reply. Operators of metallurgical plants should be interested enough in accident prevention to contribute whatever aid they can toward reducing accidents in their plants by rendering as complete a report as possible at the close of the year. Hence it is hoped that for the year 1920 those few companies who did not report to the bureau for 1919 will reconsider this matter and furnish a complete report. CLASSIFICATION OF INJURIES FOR 1917 AND 1918. Many of the States now have compensation laws, and in order to conform with their classifications the bureau's classification of serious and slight injuries is on a 14-day (2 weeks) basis. The classification of injuries at mills, smelters, and auxiliary works includes three groups, as follows: 1918 1917 1. Fatal 94 116 2. Serious (time lost, more than 14 days): (a) Permanent disability- Total y 5 Partial 247 202 (6) Others 3,028 3,302 3. Slight (time lost, 1 to 14 days, inclusive) 9,411 10^ 069 12,693 :-- 13,578 Total 12,787 13,694 ^Permanent total disability: Loss of both legs or arms, one leg and one arm, total loss of eyesight, paral- ysis, or other condition permanently incapacitating workman from doing any work of a gainful occupation. 6 Permanent partial disability: Loss of one foot, leg, hand, eye, one or more fingers, one or more toes, any dislocation where ligaments are severed, or any other injury known in surgery to be permanent par- tial disability. ACCIDENTS AT ORE-DRESSING PLANTS. The number killed in the ore-dressing plants in 1918 was 35, or 1.55 per 1,000 300-day workers employed, as compared with 47 in 1917, when the fatality rate was 1.93. The total number of injuries in 1918 was 3,142, as compared with 2,952 in 1917. Table 2 shows the number of employees by States, the number of days' work performed, and also the number killed and injured. Table 3 shows the fatalities by causes and States, and Table 4 the nonfatal injuries, classified by causes and States, during the calendar year 1918. Table 5 is a summary of the accidents by causes and by States for the the years 1913 to 1918, inclusive. 8 ACCIDENTS AT METALLURGICAL WORKS DURING 1918. ACCIDENTS AT SMELTERS. In 1918 the number of men killed at smelting plants was 42, or 0.92 per 1,000 300-day workers, as compared with 1.05 per 1,000 in 1917. There were reported 6,743 injuries, or 148.40 per 1,000. Table 6 represents a summary of accidents at smelting plants, by causes and by States, showing the number killed and injured during the calendar years 1913 to 1918, inclusive. Table 2 shows the number of men employed and the number of days worked at smelters by States for the year 1918. It also shows the total number of killed and injured for each State. Tables 3 and 4 show fatalities and injuries by causes and States for 1918. ACCIDENTS AT COPPER METALLURGICAL PLANTS. As the mills and smelters treating copper ores represent such an important part of the metallurgical industry of the United States, as well as a branch that is readily segregated, Tables 11 and 12, follow- ng, have been compiled from the reports of copper companies whose records appear reasonably complete, and at whose plants efforts are being exerted to maintain safety organizations. These figures rep- resent 44 ore-dressing plants and 25 smelters in various parts of the country, employing 8,222 men at mills and 12,363 at smelters in 1918. Similar figures for a few selected companies were published by the bureau for years 1915, 1916 and 1917. ACCIDENTS AT AUXILIARY WORKS. Auxiliary works are intended to include machine shops, carpenter shops, yards, and general construction, all of which, though forming part of the metallurgical plants, should not be included in the actual operating departments. The returns for 1918 show 18,044 men employed, with 17 fatalities and 2,808 injuries. Reduced to the 300-day basis, this represents 20,111 300-day workers, with a fatality rate of 0.85 and a nonfatal-injury rate of 139.63 per 1,000. A large percentage of nonfatal injuries was due to hand tools, falling objects, and falls of persons.
