OBSI 03-2000 Page 4 EN 13092: I999 Introduction This European Standard provides a framework to ensure that sampling and inoculation procedures meet workplace and environmental safety requirements with respect to microorganisms. Such proce
18、dures may need to be carried out in parallel with other requirements such as prevention of process contamination. Samples from a biotechnological process often need to be taken for off-line analysis, thus breaching the integrity of a closed system. The most common example is taking samples to monito
19、r the status of the process or to verify the specifications of the product. In a comparable way the integrity is breached when an inoculum is introduced into a closed system from the outside. Both situations have potential for release of microorganisms into the environment. Selection of appropriate
20、sampling and inoculation devices is one factor in the overall safety. In this respect, well designed and manufactured sampling and inoculation devices are most important factors to safety. However, the operation and maintenance of a sampling or inoculation device have a significant influence on the
21、overall safety. This is particularly because the consequences of release due to poor operation or maintenance are often greater than the consequences of incidental release due to the design of the sampling and inoculation devices. I Scope This European Standard gives guidance to the manufacturer of
22、sampling and inoculation devices on providing instructions in the manufacturer?s documentation accompanying his products in accordance with prEN 13312-3. It has the purpose of pointing out to him which hazards can occur during operation, so that he can take these into account in an adequate way duri
23、ng construction and will be in a position to formulate information for use giving adequate consideration of safety. This European Standard can also provide a framework for the user of sampling and inoculation devices to assess new or existing sampling or inoculation devices to implement a safe opera
24、tion and maintenance regime by restricting release, as necessary, of microorganisms into the workplace and the environment. Sampling and inoculation include the transfer of microorganisms from one closed system into another closed system like collection of samples or inoculation of a fermenter with
25、a starter cu Iture. This European Standard applies where the sampling or inoculation procedures include hazardous or potentially hazardous microorganisms used in biotechnological processes and/or where exposure of the worker or the environment to such microorganisms is restricted for reasons of safe
26、ty. This European Standard is not applicable to transport to and from a safe place and final analysis of a sample, nor is it applicable to sampling of raw materials and air sampling devices used to determine microbial air quality in the workplace.

However, sterile conditions can be regarded as established by using an
37、accepted or recognized method of sterilization. NOTE 2 The process of inactivation of viable microorganisms during a sterilization procedure is usually described by an empirical mathematical function, commonly an exponential function. By their mathematical nature, such functions can be reduced to ve
38、ry low numbers, but not to zero. However, these empirical functions can be applied to control or assess the process parameters of a sterilization procedure to realize a desired degree of inactivation of viable microorganisms. 3.17 user organization responsible for the biotechnological process who us

40、rsons and/or the environment the release of microorganisms during sampling or inoculation should be restricted. To control the contact of microorganisms with the workplace and the environment, the potential routes of release from the sampling or inoculation device should be identified and assessed.
41、These routes of release should be assessed against operating criteria which take into account the hazardous nature of the microorganism. The following situations should be assessed: - release of microorganisms during routine sampling and inoculation (including release by leakage); - release of micro
42、organisms after the sampling or inoculation procedure due to insufficient inactivation and/or removal of microorganisms when the sampling or inoculation device is opened or dismantled. 4.2 Types of hazards The types of hazard presented are dependent upon the type of device and its usage during sampl
43、ing and inoculation. The following hazards should be taken into account: - wrong sequencing of valves leading to a number of consequences such as discharge to drain, steam to the workplace, and process fluid to workplace environment; - sampling from a closed system into an open system could result i
44、n generation of aerosols and hence could cause release of microorganisms to the environment; - withdrawal of sampling or inoculation container resulting in leakage such as aerosols and/or seepage; - maintenance or dismantling being carried out without appropriate inactivation procedures; - sampling
45、often requires withdrawal of a quantity of non-representative material (e.g. first running). Safe collection and disposal of this part of the sample is needed; - sampling and inoculation containers could be dropped onto the floor by accident causing breakage and spill; - brittle (e.g. glass) bottles
46、 could be more vulnerable to shatter, e.g. by contact with steam or collision if the surface has become damaged by score marks or become chipped; - sampling and inoculation devices could be subjected to pressures greater than originally envisaged thus leading to leakage or to a bursting of the conta
47、iner. Examples are a location of the sampling and inoculation devices at the base of a tall tank where the hydrostatic pressure could be significant or an overpressure of gases in the headspace; OBSI 03-2000 STDmBSI BS EN L3092-ENGL 2000 Lb24669 0835369 929 Page 9 EN 13092: 1999 - sampling and inocu
48、lation devices using needle and septum could result in leakage with repeated insertion; - injury with a needle containing microorganisms could be significant; - poor installation or mounting of the sampling or inoculation devices could interfere negatively with the leaktightness, sterilizability or
49、cleanability. Possible additional hazards should be investigated by the user dependent upon the particular installation and use of the sampling and inoculation device. NOTE EN 12460 gives a guidance on equipment selection and installation in accordance with the biological risk (see l). 5 Methodology for preparation of a safe operation21 procedure 5.1 General The manufacturer should provide an instruction handbook for safe and faultless operation, containing information for using the sampling and inoculation device.
