Purchasing Records

Methodology. All internal sales and purchase records are computerized. This makes their retrieval and manipulation relatively quick and easy. 

Quotations for equipment costs from fabricators or suppliers are the most accurate. Therefore most companies base their costs on (1) quotations from fabricators, (2) past purchase records updated with... 

Still perfectly legal to buy in whatever amounts you want. The only catch is that the company you buy it from has to keep a record of the purchase for DBA inspection. One company (Liberty Natural Products) says that they just mail the purchase records to the DBA at the end of each month. This sounds reasonable to me since I would imagine that it would mean that the DBA would not have to perform its intrusive little routine of going thru the firm s records at their place of business. Another company (Creative Fragrances) said that they just let the DBA come in and take a look at the sassafras/almond purchases. This happens once every 1-3 months. 

Sources of Information for Material Balance. There are many sources of information in establishing material balances for the various unit operations within the plant. Data may be obtained from sample analysis and measurements of raw input materials, raw material purchase records, material and emission inventories, equipment cleaning and validation procedures, batch composition records, product specifications, operating logs, standard operating procedures, and manuals. 

Determine inputs. The inputs to the process and to each unit operation need to be quantified. As a first step toward quantifying raw material usage, purchasing records should be examined this readily gives an idea of the quantifies involved. The raw materials purchases and storage and handling should be recorded in a table format in order to derive the net input to the process. 

Other regulations, such as Form R reporting, require annual usage amounts. If your oiga-nization maintains adequate purchasing records, the chemical inventory snapshot can help reconcile estimated usage amounts for the year. 

Other substances (see also Sect. 2.4.7) will be identified by individual Countries as requiring controls on their purchasing, record keeping and storage and use e.g. diazepam, codeine ergotamine and ephedrine. There are also substances which may be hazardous in another way i.e. the explosive nature of potassium permanganate. Pharmacies must be aware of these requirements and comply with all local legislation. 

The best way to prepare a comprehensive list is to survey the workplace. Purchasing records may also help, and certainly employers should establish procedures to ensure that in the future purchasing procedures result in MSDSs being received before a material is nsed in the workplace. 

Missing or illegible fuel receipts. Photocopies are allowed, but not always encouraged by states. For fuel receipts that are hard to read, make a photocopy right away. Put the city and state on the fuel purchase record.
