1. Use recognized food safety rapid detection technology for rapid detection.
2, the use of on-site rapid detection technology discovery and screening results shall not be directly used as the basis for law enforcement.
3. If the preliminary screening results show that it may not meet the food safety standards and related requirements, sampling inspection shall be conducted in accordance with the relevant provisions of the Food Safety Law.
Matters needing attention in quick detection of on-site sampling:
1. Ensure the integrity of instruments, equipment and accessories, carefully record the past of instruments, and ensure that accounts, cards and materials are consistent.
2, regular maintenance and maintenance of instruments, timely troubleshooting, maintenance records, large equipment cleaning and maintenance 2-4 times a year.
3. Be sure to read the instruction manual carefully before use, check your own protection device as required, and control the ambient temperature, humidity, continuous working time, power supply voltage, etc. , and pay attention to moisture, dust and corrosion.
4. Managers must be familiar with the performance and operating procedures of toxic gas alarms, improve the technical files of large-scale equipment, and properly keep the technical data and operating instructions of general equipment.
5. Check the power supply regularly, stop the machine immediately and report to the person in charge to prevent the instrument from being damaged due to short circuit and prolong its service life.
The so-called rapid detection refers to the rapid detection of substances to be detected by using rapid detection equipment, test paper, kit or physical and chemical methods within a certain period of time. Rapid detection has attracted more and more attention because of its simple operation and short determination time. Fast on-site detection and sampling is the key.
All kinds of toxic and harmful gas detectors have their fixed detection range. Only when the measurement is completed within its measuring range can the instrument be accurately measured. If the sensor is measured outside the measuring range for a long time, it may cause permanent damage to the sensor. For example, LEL detector, if used carelessly in an environment exceeding 100%LEL, may completely burn the sensor.
Moreover, there are toxic gas detectors, which can also cause harm if used in high concentration for a long time. In a word, the toxic and harmful gas detector is a powerful tool to ensure industrial safety and workers' health. We should choose the appropriate gas detector according to the specific environmental conditions and required functions.
At present, the detectors we can choose are fixed/portable, diffused/pumped, single gas/multi-gas, inorganic gas/organic gas and so on. Only by choosing appropriate gas detection instruments can we really get twice the result with half the effort and prevent problems before they happen.
