- When you arrive the laboratory, the first thing is that you must wash your hands with a disinfectant soap for your immediate sanitization.
- Eating anything in the laboratory area and smoking is strictly prohibited. Do not put anything in your mouth such as pencils, labels, or fingers. Do not store food in areas where microorganisms are stored.
- Purchase a lab coat and safety glasses and use them. Leave protective clothing in lab and do not wear it in non-lab areas.
Some of the tips given by Tesilab

- Avoid loose fitting items of clothing. Wear appropriate shoes (sandals not allowed) in the laboratory.
- Backpacks, purses and quotes should be placed in the cubbyhole by the front door of the lab. Place needed items on the floor near your feet, but not in the aisle.
- Disinfect work areas before and after use with 70% ethanol and fresh 10% bleach. The regular disinfection of the laboratory surfaces must be done using appropriate disinfectants like hypochlorite solution which kills almost pathogenic microorganisms.
- Label everything clearly.
- Caps and lids of reagents, solution bottles, and bacterial must be replaced properly in order to prevent contamination and petri dishes must not be opened directly in the lab unless absolutely necessary.
- Inoculating loops and needles should be flame sterilize in a bunsen burner before you lay them down.
- Turn of bunsen burner when not in use. Long hair must be restrained if bunsen burner are in use.
- Flame sterilization using alcohol must be done so carefully and it must be kept in mind that no papers or similar materials that can catch fire easily are nearby.
- Treat all microorganisms as potential pathogens and culturing of microorganisms must be done inside a special sterilized laminar flow hood and not outside it because many air-borne microorganisms can be spread.
- Wear disposable gloves when working with potentially infectious microbes and samples. If you are surely working with a pathogenic sample, you must handle it with extra care so that it doesn’t spill out on you or on any surface of the laboratory.
- Sterilize equipment and materials.
- Never pipette by mouth.
- Consider everything a bio hazard. Do not pour anything down the sink. Autoclave liquids and brought cultures to sterilize them before discarding.
- Dispose off all solid waste material in a biohazard bag and autoclave it before discarding in the regular trash.
- There are a special column of safety equipment in the laboratory which you must be aware of so that in case of any emergency you can make use of those safety equipments.
- Dispose of broken glass in the broken glass container.
- Dispose of razor blades, syringes, and sharp metal object in the “sharps” container.
- If by any chance, there is any type of spill of sample or culture or any media, you must immediately contact your instructor or mentor so that he/she can help you and find a solution to remove it from the surface. If you’re able to clean the spill by yourself do it immediately.
- In the same way, in case of any mishappening or sudden accident, you must immediately report to your instructor for the immediate help.
