Johnson of our Wichita loss Prevention Department, The purpose of this visit was to re-cheek the levele of atmospheric lead In bagging operations In the calcine department and in the ojdde '-'are room. No samples were taken at the roasting furnaces and the bag bouse as these operations are temporarily suspended. In order to complete this evaluation, a total of 9 air samples were taken for atmospheric lead according to accepted sampling procedures. The results of these samples are given on the Data page of this report. Conclusions, based on the air sample results are presented for your consideration. ettcjccms 1. The levele of all air samples taken for atmospheric lead with the ex ception of -amples #5 and f?, are in excess of the maximum allowable concentration for continuous 8 hour exposure, and thought should be given to permanent controls. 2. The levels of atmospheric lead at the general area in the packing department and the south part of the ware room were less than the maximum allowable concentration for continuous 8 hour exposure. 3. It was noted that smoking is allowed near the coal stove in the cal cine department. This practice should be discontinued for obvious reasons. KCttJffiMEATIOhS 1. Provide a system of local exhaust for all packing stations in rhe pack ing department. The exhaust system should be designed so that it will exhaust air from the operator's position across the top of the bag being packed and to the outside atmosphere. The system should be capable of a hood face velocity of 200 lineal feet per minute. ' 2. Eliminate the .'making currently allowed in the calcine department to reduce the chance of excessive lead intake by Ingestion. LIBERTY MUTUAL INSURANCE COMPANY 0007-SWP-000031022 .aTAMEAROs The maximum allowable concentration of lead in air, aa agreed to by leading goverrmental and industrial hygienists, is 0.20 milligrams of lead per cubic meter of air for continuous 8 hour exposure. If continued ex posure to levels in excess of this value are permitted, lead Intoxication and finally lead poisoning may develop in exposed personnel. qsfflggpa The results reported on the Data page of this report are, in general, about the same as the samples taken during our June, 1956 survey. Host of the atmospheric lead level is due to the unexhausted peeking units and the floor dump at the re-pack packer. The lead levels are presently well controlled by the mandatory resLraior protection. It is felt that packer exhaust would be more satisfactory. This has been recOtarended even though your plant can't consider it until 1st: 1958* ye hope exhaust will be installed when plant conditions permit. The on'y other recommendation pertains to the current practice of employees smoking in the calcine department. Handling of cigarettes with lead con taminated hands is contrary to all accepted lead safety programs and should bs discontinued, as this practice allows lead Intake by ingestion, employees should also be instructed not to carry cigarettes, etc., into a lead area. wHG/Jh iJ.

C, Galvin of oar Wichita Loss Prevention Department. The purpose of this visit was to determine, by sampling, the levels of atmospheric lead at various oper ations in your plant. The locations sampled were the baghouse 3, packing department, and the oxide warehouse. coi-rcius:oirs A. Baghouse B. f 1, flith the exception of the fan room adjacent to the baghouse all air samples showed concentrations of lead in air in excess of the maximum allowable concentration. The highest concentrations of lead in air were found on the catwalk during the bag shaking operations, malting controls necessary. S. racking Department 1. Levels of lead in air at all bagging operations sampled were in excess of the maximum allowable concentration end should be controlled. Local exhaust ventilation is recomaen&ed to control the exposure. 2. Levels of lead in air at the blending operation of leaded zinc oxide and litharge were above the maximum allowable concentration and should be controlled. Local exhaust ventilation is recommended to control the exposure. . C. Oxlde_tfarehouse 1. Levels of lead in air in the oxide warehouse were above the maximum allowable concentration and are in need of control. 0007-SWP-000031026 LIBERTY MUTUAL INSURANCE COMPANY I N18331.03 ?j;ccH-:r.TiiTic::s 1. Baghoaee B; It is recommended that the present sponge type respira tory protection be replaced, with respirators approved for the ex posure. Several types of respirators approved for the enosure are discussed in the discussion section of this report. 2. packing Department; Provide a system of local exhaust for all packing stations in the packing department. The exhaust system should he designed so that it will exhaust air from the operators position across the top of the hag being packed and to the outside of the plant. The system should be capable of an inward velocity at the hood face of 200 feet per minute average. 3. racking Department! Provide a system of local exhaust for the dumping point of leaded zftic oxide and litharge for the 18 M blending operation similar to recommendation #2 above. U, Pi-id* t'arehoase: A. The most efficient '..'ay to lower the atmospheric lead levels ........... in the warehouse is to provide general area ventilation by roof fans. It 1b recommended that these fans be installed. 3, In addition to A above a systematic vacuuming of the ware house on a periodic basis will also help to reduce the atmospheric lead levels. 0007-SWP-000031027 LIBERTY MUTUAL INSURANCE COMPANY j s t aiiiapibs The maximum allowable concentrations for lead In air is 1.5 milligrams per 10 cu'oic meters of air for continuous S hour per day exposure. Intermittent exposures to concentrations greater than 1.5 milligrams may be permitted provided the average of 1.5 is not exceeded. Continuous exposure to more than the "grl"""" allowable concentration may cauBe lead in toxication. DISCUSSION 1. 3ahoase_B.. The present respiratory protection used is the baghouse operations are not approved forf.ead in air and sulfur dioxide. As I gathered from Hr. Keith's conversation, other respirators have been tried 'out have not been comfortable. In investigating proper type respirators I learned of two types that are of--the same basic construction as the ones in use but will protect against the toxic substances in air at the operation, l2_I Willson Series 300, double cartridge respirator using a iftl and #Hbl5 cartridge together. E_2 M-S-A gas fume respirator. Both of the above respirators can be purchased thru the local supplier of safety equipment in your area. 2. Backing Boom It is possible that in addition to the dust generated by the packing operation there are a few Bystem leaks allowing dust to 'oe dispersed into the atmosphere. When the ventilation system is installed, these leaks if any, should be eliminated. Attached to this report are several sketches outlining the type of exhaust hood recommended. 0007-SWP-000031028 LIBERTY MUTUAL INSURANCE COMPANY 3. Panklag Department Blander: A sketch is also appended to illustrate the exhaust hood proposed. As an alternate method the mixing Sin could be exhausted. h. Oxide Warehouse: She high concentration of dust in this area probably was generated by the power truck operations and the windy conditions outside at the time of the surrey. Suggested general area ventilation will eliminate the dust levels. 5. Medical Control! This was discussed at the tine of our fall visit but should be high lighted here, ffce program is adequately checking for lead levels is all exposed personnel and will maintain a medical check os the existing engineering controls for lead dust.
