How To Maintain The Electrical System of A Fume Hood

The maintenance of the electrical system of fume hoods is the key to ensuring their long-term stable operation and laboratory safety. Here are some suggestions for maintaining the electrical system of fume hoods:

First, regular inspections

Frequency: It is recommended to conduct a comprehensive inspection at least once every quarter, or adjust the inspection frequency based on the usage frequency of the laboratory and environmental conditions.

It includes power plugs, sockets, switches, buttons, indicator lights, and line connections, etc. Check for any signs of damage, loosening or aging.

Second, cleaning and maintenance

Surface cleaning: Regularly use a clean cloth or vacuum cleaner to clean the surface of the electrical system to remove dust and dirt, preventing dust accumulation from affecting heat dissipation and causing short circuits.

Internal inspection: In the event of a power outage, check the electrical system for any foreign objects or moisture inside, and clean and dry them in a timely manner.

Third, functional testing

Fan operation: Test the operation of the fan to ensure there is no abnormal noise, vibration or overheating.

Lighting system: Check whether the lighting system is working properly and whether the brightness is sufficient.

Control panel: Test various function buttons on the control panel, such as wind speed adjustment and lighting switch, to ensure normal operation.

Fourth, grounding and insulation inspection

Ground resistance test: Use a ground resistance tester to measure the ground resistance of electrical equipment to ensure it meets safety requirements.

Insulation performance inspection: Use an insulation resistance tester to test the insulation performance of electrical equipment to prevent electrical leakage and short circuits.

Fifth, line protection

Overload protection: Ensure that the electrical system has overload protection function to prevent damage to electrical equipment due to excessive load.

Short-circuit protection: Install a short-circuit protector to promptly cut off the short-circuit current and prevent the occurrence of fire and other safety accidents.

Sixth, Recording and reporting

Maintenance records: After each maintenance, the maintenance date, maintenance content, problems found and handling methods, etc. should be recorded to facilitate subsequent tracking and inquiry.

Problem Report: For any issues identified during the inspection, they should be promptly reported to the relevant person in charge, and corresponding solutions should be taken to ensure the normal operation of the electrical system and the safety of the laboratory.

Seventh, professional operation

Professional personnel: Electrical system maintenance should be carried out by professionals with relevant qualifications to ensure operational safety and the accuracy of inspection results.

Professional training: Regularly provide laboratory personnel with training on electrical safety knowledge and operational skills to enhance their safety awareness and emergency response capabilities.

Through the above measures, the electrical system of the fume hood can be effectively maintained, its service life can be prolonged, and the safety and efficient operation of the laboratory can be ensured.
