Materials inventorying, building

Assets are classified as current or fixed, and liabilities as current or long-term. Fixed assets are material items that have a relatively long life and normally include land, buildings, plant, vehicles, etc. They are held for the specific purpose of earning revenue and are not for sale in the normal course of business. Current assets include cash and those items that can be fairly easily converted into cash, such as raw-materials inventories, etc. In contrast to fixed assets, current assets are acquired for the specific purpose of conversion into cash in the normal course of business. However, what is regarded as a fixed asset by one type of company might be regarded as a current asset by another. For example, a chemical company would normally classify its vehicles as a fixed asset. However, a company whose primary business was to sell vehicles would classify them as a current asset. 

Radioactive material inventories in each remote radioactive material storage area (i.e.. Building 6596 east highbay/Chapel, Building 6597, and the monorail storage holes) will be limited by procedure (ref. Table 3C-11, Prevention Features. Administrative) to less than the Hazard Category 2 threshold values in accordance with DOE-STD-1027-92 (DOE 1992c). 

The total inventory of flammable material that could be released was determined, and the TNT equivalence method (from Reference 5) was applied. Using this information, an incident side-on overpressure of 3 psi at 150 ft (0.21 bar at 45 m) was calculated. On this basis, it was determined that the building could sustain the maximum anticipated blast overpressure, and no further evaluation was needed. 

One of the best ways to determine that potential is to examine the Material Safety Data Sheets (MSDS), which by law in most jurisdictions must be provided by the manufacturer for any hazardous material used in the workplace and made available to the employees by plant management. The MSDS provides all the information necessary to determine the hazard potential and the requirements for control of any hazardous substance. Still other information can be found in the various guidelines published by the American Industrial Health Association, or by the U.S. National Safety Council, or by NIOSH (the U.S. National Institute for Occupational Safety and Health) or various other national, state, or provincial government bodies. (See Appendix II for information on sources.) Once you have an inventory, of course, you can start relating potential health problems to possible sources in particular areas. Also, in the process of preparing this report, you will begin to build an invaluable library that will stand you in good stead for further consideration of the problems at hand. 

Inventory of hazardous material in pipes can also be minimized by using the hazardous material as a gas rather than as a liquid. The Dow Chemical Exposure Index (14) is a tool that can be used to measure inherent safety with regard to potential toxic exposure risk. Table 2 shows the reduction in the Chemical Exposure Index that can be realized by handling a number of hazardous materials as a gas rather than as a liquid, assuming that the same-size pipe can deliver the required flow rate. Figure 6 shows the decrease in the hazard zone (toxic cloud footprint) that resulted from relocating a chlorine vaporizer from a production building to... 

On Aug. 1, a concern had 10,000 lb of raw material on hand which was purchased at a cost of 0,030 per pound. In order to build up the reserve, 8000 lb of additional raw material was purchased on Aug. 15 at a cost of 0,028 per pound, and 2 days later 6000 lb was purchased from another supplier at 0.031 per pound. If none of the raw material was used until after the last purchase determine the total cost of 12,000 lb of the raw material on an inventory or cost-of-sales account for the month of August by (a) the current-average method, (b) the fifo method, and (c) the "lifer method. 

It should be clear from Figs. 5.12 to 5.14 that it would be impossible to build a process so that the flow of heat would balance itself along the three paths for all operating conditions. We could not even bank on this happening for the design conditions because of imperfections in our basic data. We need a control system to help direct the flow of heat just as we need controllers to manage material flow and inventory.
