The maintenance cycle of fume hoods mainly depends on the frequency of use, the requirements of the working environment and the manufacturer's suggestions. The following are some common maintenance cycle suggestions:
Cleaning: After each use, the workbench surface and internal residues of the fume hood should be promptly cleaned to keep it clean and tidy. In addition, the inner and outer surfaces of the fume hood should be wiped regularly (such as once a week) with a soft cloth and neutral detergent to prevent the accumulation of stains and dust.
Filter inspection and replacement: The filter is a key component inside the fume hood, and its replacement cycle is usually 6 to 12 months. In laboratories that are frequently used or handle a large amount of harmful substances, filters may need to be replaced more often. It is recommended to regularly check the status of the filter and replace it in a timely manner according to the actual situation.
Wind speed test: At least one wind speed test should be conducted annually to ensure that the exhaust performance of the fume hood meets safety standards. This helps to detect and solve the exhaust problems of fume hoods in a timely manner.
Electrical system inspection: The inspection of the electrical system should also be conducted once a year, covering electrical connections, control panels, and alarm systems, etc. This helps ensure the normal operation of the electrical system of the fume hood and avoids potential safety hazards.
Comprehensive inspection and maintenance: It is recommended to conduct a comprehensive inspection and maintenance of the fume hood every six months or annually, including cleaning, checking the operating status of each component, and replacing damaged or aged parts, etc. This helps ensure the long-term stable operation of the fume hood and extend its service life.
If any abnormal conditions are found in the fume hood during use, such as weakened airflow or the generation of unpleasant odors, immediate inspection and maintenance should be carried out.
In cases where the laboratory environment is poor or the fume hood is used frequently, it may be necessary to shorten the maintenance cycle to ensure the normal operation of the fume hood.
In conclusion, the maintenance cycle of fume hoods should be flexibly adjusted according to the actual situation. It is recommended that laboratory managers formulate appropriate maintenance plans based on the usage frequency of fume hoods, the requirements of the working environment, and the manufacturer's suggestions, and strictly implement them to ensure the long-term stable operation of fume hoods and extend their service life.
