The laboratory is a vital base for scientific research. Strengthening safety and sanitation management and establishing sound operational rules and regulations are essential conditions for ensuring the smooth conduct of research. All principal investigators (PIs) and staff members must give high priority to these matters and ensure that safety and sanitation measures are implemented in all aspects of work, so as to prevent accidents and protect state property as well as the lives and safety of faculty, staff, and students. To this end, the following regulations are hereby established:

Article 1
Strict access control shall be enforced. All doors of the laboratory and offices are equipped with an intelligent smart‑lock system. All laboratory researchers and graduate students must use their key cards to unlock the doors. The issued key cards must be properly kept and shall not be lent to others. When a researcher transfers to another position or a graduate student graduates, the key card shall be returned voluntarily. In case of loss, it must be reported immediately, and the unlocking authorization shall be terminated to ensure laboratory security.

Article 2
Each research group leader shall designate a responsible person to regularly inspect instruments, equipment, and electrical wiring, perform timely maintenance, troubleshoot equipment faults, and eliminate potential hazards. Equipment shall not be operated with known faults, and damage to instruments and equipment must be strictly prevented. All instruments shall be maintained in good working condition. Any unsafe factors must be reported to the relevant departments without delay, and measures shall be taken to eliminate them promptly.

Article 3
Unauthorized electrical wiring is prohibited in the laboratory. All wires, plugs, sockets, and power strips for instruments and equipment must comply with electrical safety requirements. Damaged items shall be repaired immediately. When adding large‑scale equipment, the capacity of the power supply circuits must be considered; if necessary, circuit upgrades shall be carried out. Overloading is strictly prohibited to ensure safe electricity use. Before leaving the laboratory after work, personnel shall check water, gas, and power supplies and ensure that doors and windows are securely closed.

Article 4
Strict safety management shall be applied to flammable, explosive, and highly toxic substances. Each research group must assign a designated safety officer, establish a registration system for storage and usage, and also properly manage valuable materials and precision instruments.

Article 5
In laboratories using gas cylinders, hydrogen and oxygen cylinders must not be stored or used together. Contact with hazardous materials such as fluorine, chlorine, and ignition sources must be strictly avoided.

Article 6
Open flames must be attended at all times. It is prohibited to use gas or electric stoves in the laboratory for cooking, heating food, or warming rooms.

Article 7
It is forbidden to pour easily clogging debris, strong acids, strong bases, or toxic organic solvents into sinks. Waste liquids of corrosive nature must be collected in suitable containers, labelled, and placed at designated locations for unified disposal. Floating or easily dispersed materials shall not be placed in sinks to ensure unobstructed drainage.

Article 8
The laboratory shall be maintained as a civilised and pleasant working environment. The premises shall be kept quiet, clean, and tidy; loud noise is prohibited. Unauthorised personnel are not allowed to enter the laboratory. Visitors for sightseeing purposes may enter only with the approval of the responsible supervisor and must be accompanied by a designated staff member. Visits shall not interfere with normal laboratory operations.

Article 9
Supervising faculty members shall regularly educate graduate students on safety knowledge and operational procedures. Special attention to safety is required during holidays and overnight overtime work. Such work must be conducted under the supervision of a faculty member or with a designated person in charge. Evening work must end and personnel must leave the laboratory by 11:00 p.m. Any extension beyond this time or all‑night experiments require prior consent from the research group leader and must be reported to the laboratory office for record.

Article 10
Those who neglect their duties or violate the above regulations, thereby causing accidents, shall be dealt with according to the severity of the circumstances.
