Marking by nature can be divided into attribute marking and state marking.
Attribute marking specifies the inherent characteristics of the thing, it is unchanged throughout the process from beginning to end, with the characteristics of uniqueness and traceability.
State identification is the ability to identify things to meet the specified quality requirements, generally time-limited and variable characteristics, that is, the identification of the object corresponds to a different period of time, there can be different states.
Laboratory accreditation activities in the identification of management objects are:
(1) documents, files, records, reports;
(2) test samples;
(3) instrumentation, measuring instruments and standardized substances;
(4) drugs and reagents;
(5) environmental areas;
(6) personnel ;
(7) Other.
Laboratory accreditation how to make use of various types of signs in the laboratory
Signage management is based on the attributes of the item, the identification of the item for the design, organization, paste, adjust the dynamic management process. According to the different laboratory management objects,
The application of attribute marking and state marking to distinguish between management objects.
The two marking methods can cross each other, mixed use. However, for documents, files, records, reports (certificates), test samples, measuring instruments, standardized substances, these objects, first of all, to identify the uniqueness of clear items. Then, the state of its existence for identification, and finally according to the changes in the identification of the object for the corresponding identification of the state adjustment. Such as a file for a unique number, and then determine its "controlled", "effective", "invalid" and other states of existence. For drugs, reagents, environmental areas, personnel, other objects need to be labeled with their nature, status, department and so on. All of these are specified in the guidelines.
Documents, files, records, reports
For this category of objects, documents, files, records, and reports should first be uniquely indicated with numerical symbols and signatures. Each category can start with a letter, and then use numbers in sequential numbers, or directly with numbers. After the unique identification is compiled, it is necessary to mark the document with a stamp on the controlled, invalidated, and changed situation.
Inspection samples
First of all, the numbers and symbols to indicate the uniqueness of the identification of test samples, and then use the label to indicate the samples to be inspected, in the test samples, test samples, retained samples. For the end of the sample to use "red", "yellow", "green" that is, "unqualified", "To be determined", "qualified" labeling for identification. At the same time, the need to return to the enterprise samples, set the return area signage, and the need to return the samples placed therein.
Instrumentation, measuring instruments and standard substances
For instrumentation, measuring instruments and standard substances according to the condition of the instrument and calibration, first of all, the establishment of instrumentation ledger and instrumentation list, with numbers, symbols for the uniqueness of the identification, so that the instrumentation on the ledger with the same three-color logo number number consistent. At the same time, according to the status of the instrument, with "red", "yellow", "green" three-color mark to indicate the instrument "out of service "Red", "yellow", "green" three-color flag to indicate that the instrument is "out of service", "quasi-use" and "qualified" status.
Drugs and reagents
First of all, we should establish a drug and reagent account, categorize and register the drugs, and at the same time, place a sign indicating acidic reagents, alkaline reagents, salt reagents (which can be subdivided), and microbiological reagents.
Environment, region
For chemical hazards, drugs, harmful organisms, ionizing radiation, high temperature, high voltage, impact, and water, gas, fire, electricity and other hazards to the safety of the work area, not only should it be protected by isolation measures, but also should be used with the name of the region (eg, "toxic hazards, "explosive hazard", "high pressure hazard") signage with warning graphics to indicate the danger of the region, to remind everyone to pay attention.
Personnel
Personnel can be distinguished by dress code and badges.
Other
Icons can be used to indicate that smoking is not allowed, saving electricity, and so on.
Marking management in the laboratory application should pay attention to the problem
According to the above, the establishment of a unified standardized, convenient and comprehensive marking system can be done, but also pay attention to the following details:
(1) how to establish a marking system (what to arrange, how to arrange, who is responsible for it, to determine the relevant personnel), which needs to be harmonized and coordinated.
(2) The logo should not be too large, paste parts should not affect the normal work of the equipment.
(3) To regularly check the signs, and timely replacement of expired signs, dynamic management, to avoid errors and accidents.
(4) The text, graphics, and symbols of the logo should be clear and intuitive, and the content should be simple and easy for people to recognize.
(5) The design of the logo should reflect humanization, beautiful and generous, easy to visualize, easy to understand.
(6) Correctly understand the meaning of the logo, so as not to use the wrong. In the laboratory, all the instruments and equipment and their software, standard substances should be obvious three-color identification to show its status, the status of the identification contains the necessary information (such as the date of verification / calibration, validity, verification / calibration unit, equipment from the number, the use of people, etc.). The three-color mark is qualified (green), permitted (yellow), out of service (red) three.
The meaning of the three-color signs are:
(1) qualified sign (green) that the measurement test, calibration, verification, to confirm that it meets the requirements for use.
(2) the mark of approval (yellow) indicates that there are some defects in instrumentation, but within the limits can be used, including multi-functional testing equipment, some of the loss of function, but the function used for testing work is normal, and by the inspection/calibration; or test equipment, a range of the accuracy of unqualified, but inspection/testing of the work of the range of qualified; degradation of degradation of the use of the equipment.
(3) deactivation mark (red) indicates that the current state of the instrumentation can not be used,
but by the test/calibration or repair can be used, including instrumentation damage, instrumentation by the test/calibration is not qualified, the performance of the testing equipment can not be determined, testing equipment more than the test cycle has not been inspected/calibrated, not in line with the provisions of the technical specifications for testing/calibration of the use requirements. The use of requirements.
