are other occupations where noise, monotony of work, or too rapid 

 movement causes fatigue and frequently accidents. Workmen in 

 such trades must be protected, and many state laws now provide for 

 proper gas masks, wheel and belt protectors, efficient lighting and 



other devices that 

 protect workmen 

 from the particu- 

 lar hazard to which 

 they are exposed. 

 Factories are in- 

 spected as to clean- 

 liness, the amount 

 of air space per 

 person employed, 

 ventilation, toilet 

 facilities, and 

 proper fire protec- 

 tion. Tenement 

 inspection should 

 also be thorough 

 and should aim to 

 provide safe and 

 sanitary homes for 

 workers and their 

 families. 



Inspection of food supplies. In all cities certain regulations for 

 the care of public food supplies are necessary. Inspectors are 

 appointed to see that the laws are enforced and that foods are pro- 

 tected for the thousands of people who are to use them. All raw 

 foods on stands should be covered with glass so as to prevent in- 

 sects or dust laden with bacteria from coming in contact with them. 

 Meats must be inspected for diseases. Inspection of cold-storage 

 plants, of factories where foods are canned, and of bakeries must 

 be and is part of the work of a city in caring for its citizens. 



Why is the face of this workman protected with a shield ? 



Practical Exercise 32. Visit a factory in your neighborhood and report to 

 the class on all the protection devices you found. Have you any suggestions 

 for improvement ?
