Industrial safety does not just happen. Companies 41 low accident rates plan their safety programs, work hard to organize them, and continue working to keep them 42 and active. When the work is well done, a 43 of accident-free operations is established 44 time lost due to injuries is kept at a minimum.
Successful safety programs may 45 greatly in the emphasis placed on certain aspects of the program. Some place great emphasis on mechanical guarding. Others stress safe work practices by 46 rules or regulation. 47 others depend on an emotional appeal to the worker. But, there are certain basic ideas that must be used in every program if maximum results are to be obtained.
There can be no question about the value of a safety program. From a financial standpoint alone, safe 48 . The fewer the injury 49 , the better the workman’s insurance rate. This may mean the difference between operating at 50 or at a loss.

Until recently most historians spoke very critically of the Industrial Revolution. They 41 that in the long run industrialization greatly raised the standard of living for the 42 man. But they insisted that its 43 results during the period from 1750 to 1850 were widespread poverty and misery for the 44 of the English population. 45 contrast, they saw in the preceding hundred years from 1650 to1750, when England was still a 46 agricultural country, a period of great abundance and prosperity.
The view, 47 , is generally thought to be wrong. Specialists 48 history and economics, have 49 two things: that the period from 1650 to 1750 was 50 by great poverty, and that industrialization certainly did not worsen and may have actually improved the conditions for the majority of the populace.
