H. J. Weber's paper) j UrJ Weber shoved a number of lantern slides demonstrating good and camples |of housekeeping! lighting and maintenance in our various plants. jo pointed out how the nurse could help by observing vhether employ ers usincr recommended protective devices or equipment to the best ad;e and blether this equipment is bdlng properly maintained. If they It is not, they can bring the matter to the foreman's attention or after tcj the superintendent if necessary. ! ' Nurses should know what type of equipment th Hygiene Department vhen making industrial hygiene surveys in the plants.. For this purpose eber arranged a display of a number of Instruments which are coamonly yed in field studies and demonstrated their use. The exhibit included ildget impinger and electrostatic precipitator for oolleotlng air .os of du'st and fume, *he samples are collected at the breathing zone 19 employee so that they will be representative of the air he inhales. - collection! the samples are forvarded to the hygiene laboratory in the sal Department for analysis. When the results are compared with known standard?, It. can be determined vhether or not the vorkman is working safe environment. I Thejvelometer is an instrument for meausring the air'flow through various exhaust ducts and hoods so that their efficiency can be deterI. Readings are made at varying intervals and sometimes unloosed for auctions which might have gone unrecognized, are located by this j T ^ . * -i . The |use of instruments for measuring the amount of noise in a : vas also demonstrated. Hr. Weber explained the "physics of sound * and their various frequencies and told how these may effect the l ear to cause industrial deafness. A sound level meter will determine ntensity in decibels and the octave band analyzer will disclose the rent frequency ranges. Sound of average Intensity may not cause A to the lear as long as it remains in the lover frequencies, but in frequency ranges it can be a definite hazard. The importance of ,nizing the riBlcs associated with industrial noise vas stressed be, of its injurious effect on employee health and beoause of the atlonal disease aspects involving claims for compensation. The ,al Department has nov set up a program of preplacement audiograms veral plant locations in the Chicago area so that claims of Impaired ng or occupational deafness can be more accurately evaluated. The Hygiene Laboratory has been constantly increasing Its scope tivities over the. years so that investigations are now being made of ole health hazards associated with lead intoxication, dust and fumes, nt heat, noise, solvents, explosive risks, heating, ventilation and lnation. In addition to these, analyses are made of various industrial , cutting oils or other materials used in our plants which may be ile souroes.of danger. 1 The lead control program, while only involving one or two >.ons,.l3 one that has been very satisfactory'and we have been able luce cases of lead poisoning from a group of considerable size a iars ago to only one or two sporadic cases a year in one plant at 54 I SPNY 000164
