the analogy of electrical resistance-capacitance systems.24 For two dimensional problems in steady state conduction, additional techniques of solution are found in flux plotting,6-19 and in the use of a potential tank.6-19 These methods are of most direct use in problems in which the boundaries of the two dimensional shape are made up of isothermal and adiabatic surfaces.

ACCIDENT INVESTIGATION, AN ALT SIS, AND COSTS ny can estimate its accident cost with rea sonable accuracy Every organization paying compensation insurance premiums recognizes such ex pense as a cost of accidents In some cases, medical expenses, too, may be covered by insurance These costs are definite, and they are known They comprise the insured element of the total accident cost In addition to these costs, many others arise m connection with accidents Some, such as the cost of damaged equipment, are easily identified Others, such as wages paid to the injured employee for hours dur ing which he is not producing, are hidden These items comprise the uninsured ele ment of the total accident cost Insured costs can be determined easily from accounting records The difficult part is determining uninsured costs, and the method described here will serve that pur pose The first step is to make a pilot study to ascertain approximate averages of unin sured costs for each of the following four classes of accidents Class 1--Permanent partial disabilities and temporary total disabilities Class 2--Medical treatment cases requiring the attention of a physician outside the plant Class 3--Medical treatment cases requiring only first-aid or local dispensary treatment and resulting in property damage of less than $20 00 or loss of less than 8 hours* working time Class 4--Accidents which either cause no injury or cause minor injury not requiring the attention of a physi cian, and which result in property damage of $20 00 or more, or loss of 8 or more man-hours Once average costs have been established for each accident class, they may be used as multipliers to obtain total uninsured costif in subsequent periods These costs then may be added to known insurance premium costs to determine the total cost of acci dents Example of cost estimate the study were 20 Class 1 accidents, 30 Class 2 accidents, 50 Class 3 accidents, and 20 Class 4 accidents Costs were determined and averages developed as in Table 10-A.
