Critical safety information

Despite the extensive investigations that must be undertaken prior to placing a drug on the market, it is not possible to guarantee that all safety issues have been identified. Thus, market vigilance systems must be maintained after a dmg has been launched so as to detect safety issues that were not evident prior to commercialisation. For such systems to be effective requires the participation and cooperation of the medical profession, the pharmaceutical industry and the regulators, in order that critical safety information can be identified and acted on in a timely manner.

Considering the merchant nature of the tolling business, these informal communications must still respect the confidentiality concerns and restrictions on both parties. While specific experience in allied technologies often may not be disclosed, it is incumbent on both parties to establish means to convey critical safety issues without disclosure of otherwise confidential information. 

The Safe Operating Envelope has been defined as the range of process parameters (such as temperature, pressure, flow, level, composition) that are critical to safe operation. The Safe Operating Envelope upper/lower limits are listed in the Safe Operating Envelope tables maintained under Process Safety Information. Operating beyond these limits will cause a process upset. Key maximum and minimum Emits are set based on manufacturers specifications, theoretical calculations, or operating experience. 

Students who use this lab manual will critically examine the labels on consumer products and commercial chemical products for safety information. They will attempt to solve problems for chemical companies and research proposed new industrial processes and laboratory methods. They will analyze materials and consumer products to provide third-party answers to industrial problems. They will participate in proficiency testing and identify a waste acid that is designated for disposal. Students also will learn how to think critically in order to apply chemistry principles to solve these various problems and to report to a client. Students even play the role of industrial chemists that become involved in National Chemistry Week activities. 

Flanagan (1954) developed the procedure known as the critical incident technique. This relatively simple process involves interviewing job incumbents and asking for descriptions of critical incidents in their job, and also asking what they did in the particular simation. Critical incident information could also be obtained by supervisors keeping a record of simations they have observed, and employees responses to the simation. Thus, a critical incident represents a specific job simation and a particularly effective response to that simation. The critical incident technique can easily be applied to gather safety-specific examples. A sample of employees would be asked to describe a simation which had a safety aspect and then to describe how the safety issue was handled or resolved. Of course it is necessary to ensure that the response to the simation is indeed the correct response in that it is what the organization would want an employee to do when the particular safety simation occurred. Once a number of these critical incidents have been identified, they can be formed into employment interview questions. The job applicant is presented with the question (or scenario) and is assessed on their description of how they would (or have) handle or responded to the simation, and in particular how...

A critical safety constraint to prevent friendly fire requires that the pilots of the fighter aircraft know who is in the no-fly zone and whether they are supposed to be there. However, neither the CTF staff nor the Combined Forces Air Component staff requested nor received timely, detailed flight information on planned... 

Setting up a safety information system for a single project or product may be easier. The effort starts in the development process and then is passed on for use in operations. The information accumulated during the safety-driven design process provides the baseline for operations, as described in chapter 12. For example, the identification of critical items in the hazard analysis can be used as input to the maintenance process for prioritization. Another example is the use of the assumptions underlying the hazard analysis to guide the audit and performance assessment process. But first the information needs to be recorded and easily located and used by operations personnel. 

While the term "signal" has been used commonly and widely in the area of pharmacovigilance for years, its definition has evolved over the past few years. Clearly defined terminology is critical to ensure clarity and consistency in communication of drug safety information to patients, prescribers, manufacturers, and regulators [6], and therefore, establishing a common and clear definition of a safety signal is essential. 

As editors of this book, we are pleased to see that such broad and critical safety topics have been addressed by well-established and experienced authors. We trust you will enjoy reading them and find them informative and useful in your drug safety evaluation as much as we do. 

TA-V SOPs require safety committee review. The author shall ensure that they are presented to the appropriate safety review committee (e.g.. Radiation and Criticality Safety Committee). The department manager may informally review a TA-V SOP before it is presented for safety committee review. Department managers approve TA-V SOPs based on the recommendation of the safety review committee they also approve OPs and ADPROs. In addition, approval authority for some lower order, facility-specific OPs may be delegated to a facility supervisor. 

Requirements for an independent review and appraisal system for nuclear facilities were originally contained in canceled DOE Order 5480.6 (DOE 1986). These requirements were implemented by means of the Sandia two-tiered independent safety review, as described in the NFSC and RCSC charters. The RCSC performs an annual review of HCF operations that involve radiological and criticality safety, and advises the line organization (responsible for the safe operation of HCF) on these matters. Additional information on the NFSC and the RCSC can be found in Section 17.3.3.3. 

VII. 14. The SAR should provide sufficient information or references to demonstrate that the computer code, nuclear cross-section data and technique used to complete the criticality safety assessment are adequate. The computer codes used in the safety assessment should be identified and described in the SAR, or adequate references should be included. Verification that the software is performing as expected is important. The SAR should identify or reference all hardware and software (titles, versions, etc.) used in the calculations as weU as pertinent version control information. Correct installation and operation of the computer code and associated data (e.g. cross-sections) should be demonstrated by performing and reporting the results of the sample problems or general validation problems provided with the software package. CapabiUties and limitations of the software that are pertinent to the calculational models should be discussed, with particular attention to discussing limitations that may affect the calculations. 

VII.63. The use of INF isotopics in the criticality safety analysis means that any computational methods used to predict the isotopics should be validated, preferably against measured data. The reduced reactivity in INF is due to the decrease in fissile inventory and the increase in parasitic, neutron absorbing nuclides (non-fissile actinides and fission products) that build up during bumup. Broadhead [V11.23] and DeHart [V11.24] provide information to help identify the important nuclides that affect the reactivity of PWR irradiated fuel. The INF nuclides that can be omitted from a safety analysis are the parasitic absorbers that can only decrease k jj further if included in the analysis. Neutron absorbers that are not intrinsic to the fuel material matrix (gases, etc.) must also be eliminated. 

Inventory management This feature provides critical safety-stock information that is used for coordination of procurement, sales, and production planning. 

The odier major vantageof the method is the abiliiy to use very detailed cross-section information instead of group-averaged cross sections. While much work is done usii% detailed cross sections, the lack of extensive validation of particular sets of data has thus far.prohibited the use of such data in routine criticality safety analysis.
