The Laboratory Safety Code serves to remind students of the risks and rules associated with laboratory operations, ensuring safety in hazardous environments. All students must familiarize themselves with these rules before entering the laboratory.

 

Basic Laboratory Safety Rules:

 Always wear protective gloves and lab coats to minimize physical contact, and remove combustible waste from the work area.

 Store hazardous products separately and avoid long-term storage, especially in large quantities. Empty containers may still contain dangerous residues.

 Inspect hazardous products for leaks or damage before handling them. Wash hands thoroughly after handling.

 Do not wear contaminated clothing outside the work area. Report any signs of illness immediately.

 Follow proper recycling and waste disposal protocols, avoiding the release of harmful substances into the environment.

 Only trained personnel should handle hazardous products. Follow infection control strategies, and use ultraviolet light for workplace disinfection.

 

Biological Laboratory Safety Rules:

 Only approved laboratory materials, consumables, and cells are allowed in the lab. Laboratory items must not be removed from the laboratory.

 Use syringes and needles only when absolutely necessary. Never recap or bend used needles, and dispose of them in a sharps container.

 Infectious waste must be placed in a biosafety cabinet and sealed in a zip-lock bag. Sharps, such as needles and blades, should be collected in designated sharps containers and disposed of once they reach 2/3 capacity.

 Disinfect all work surfaces before and after experiments, especially areas where GMOs are handled, using an appropriate disinfectant.

 Genetically modified bacteria must be stored in clearly labeled, secure containers. All containers must remain sealed when not in use.

 Waste from GMO experiments must be autoclaved before disposal to ensure no viable genetically modified organisms are released into the environment.

 All accidental spills involving GMOs must be reported immediately and cleaned using a disinfectant. The area should remain off-limits until decontamination is complete.

 

Heavy Metal Safety Rules:

 Work with solid heavy metal salts in a fume hood to prevent inhalation of dust or fumes. Ensure proper ventilation in the lab at all times.

 When handling heavy metal salts, double gloving is recommended to provide extra protection against potential glove punctures or contamination. Always replace both gloves if any damage is detected or after completing the task.

 Store heavy metal salts in tightly sealed, clearly labeled containers. Keep them in designated areas away from heat sources, acids, and incompatible chemicals.

 Avoid skin contact with heavy metal solutions. If accidental contact occurs, wash the affected area immediately with plenty of water and report the incident.

 Dispose of heavy metal waste, including contaminated materials (e.g., gloves, pipette tips), through designated hazardous waste disposal channels. Never pour heavy metal solutions down the drain.

 Use the minimum necessary quantity of heavy metal salts for experiments to reduce exposure risk and minimize waste.
