High operation procedures

All employees, working with highly hazardous chemicals must understand the safety and health hazards (29CFR1910.1200 - the Hazard Communication Standard) by knowing the properties of the chemicals with which they work, safe operating procedures, work practices, and emergency action. 

Higher risk activities will require more forma management systems. For example, a process that uses a highly toxic raw material may require an extensive pre-startup leak check of the process as part of standard operating procedures. 

A mismatch between operator procedures and the automatic control system of the reactor (see also Table 17) was the first active failure identified in this scenario. This precursor was still present mainly due to a shortage of people. Literally it was said that the pressure relief valve would open if the wrong value was inserted into the reactor s control system. The second precursor was the failure of the pressure relief valve (see also Table 17), which was not known to the responsible person who decided to ignore the difference between procedures and control system. The pressure relief valve failed, because resins stuck in the valve after it was used for the first time. Consequently the second time the valve was opened it was at a much higher pressure due to the build up of resins in the valve. If this second precursor had not been observed in time by damp on the pipes situated above the pressure relief valve or by the alarms in the control room a possible accident scenario existed. This was especially dangerous as the alarms in the control room are often ignored because of the high incidence of false alarms (see also Table 17), which was the third precursor present. 

In any setup, it is paramount that the electrodes get cleaned regularly. The minimum frequency, e.g., once a week, should be described in the instrument standard operation procedure (SOP), but for some methods or samples more frequent cleaning is necessary. An example is the determination of the enantiomeric purity of adrenaline in local anesthetic solutions. The samples are isotonic and contain high concentrations of local anesthetics (5—20mg/ml). The determination concerns very low concentrations of adrenaline (typically 5 pg/ml of 1-form and only a few percent of that of the d-form) and the samples are therefore injected undiluted. Furthermore, relatively high concentrations of cyclodextrin are present in the BGE. Eong sequences therefore require electrode cleaning for every sequence and this is thus described in the method procedure. ... 

Operation procedures for SAED, dark-field (DF) imaging and high-resolution observation [5,6] are briefly described here, which are utilized in our laboratory for structural investigation of crystalline polymers . As for conventional bright-field (BF) imaging, any text books [5,6] can be referred to. 

Injectable anesthetics act faster and are therefore best suited for induction of anesthesia and for short operative procedures. However recovery from injectable anesthetics is generally slower than with inhalation anesthetics. The high blood flow to the brain leads to rapid delivery of the anesthetics to their site... 

For a contract analytical laboratory, participating in GLP projects may be a significant diversion from the ongoing business but may allow the company to enter a unique market niche. Many contract analytical labs routinely handle high volumes of samples tested with standardized procedures. Most of the tests are single isolated analyses or groups of analyses, each with a standard operating procedure (SOP)... 

Previously, we developed a prototype model of automated 2DE system which enabled rapid, highly reproducible, and required minimal maintenance (6). All the 2DE procedures including lEF, on-part protein staining, SDS-PAGE, and in situ protein detection were automatically completed. The system completed the entire process within 1.5 h. Recently, an improved model of this system was capable of reliability y and portability, e.g., operational stabilities in both componentry and software, and miniaturization of whole apparatus. Followings are described system components, operational procedure, and data analysis of this 2DE system in a hands-on form. 

The principle has been demonstrated with CaLB in simple model transesterifications as well as in the enantioselective acylation of 1-phenylethanol, in batchwise and continuous procedures. The high operational stability of CaLB, which contrasts with the generally rapid deactivation in pure scC02, is one of the attractive aspects of this approach. The reaction rate was approximately eight times better than that in pure scC02 under otherwise identical conditions [96]. 

Operational procedure of capillary electrophoresis (CE) is similar to TEF. Proteins are separated in an electrical field, migrating until they reach the point where they carry zero charge. Analysis is carried out in a microcapillary tube which provides high resolution. CE can be coupled directly to a MS instrument. The superiority of CE to other analytical techniques is its high resolution. However, it is not widely used for proteomic analysis as there is no commercially available and reliable -MS instrument. 

Among the most effective of the modifications to Claus operating procedure is accurate temperature control of the catalyst beds. Gamson and Elkins (27) in the early 1950 s showed that equilibrium sulfur conversion efficiencies in the catalytic redox reaction rise dramatically as operating temperatures are lowered toward the dewpoint of sulfur. While some highly efficient subdewpoint Claus type processes are now in use the bulk of sulfur production from H2S still requires that the converters be operated above the dewpoint. Careful control of converter bed temperature has, however, contributed to improved efficiencies. This has in large part resulted from better instrumentation of the Claus train and effective information feed back systems.
