Each laboratory environment poses a unique set of hazards, including chemical, biological, physical, and radiological hazards.The following are general safe laboratory practices for personnel working in labs where hazardous chemicals are used and/or stored. See the Laboratory Chemical Safety Toolkit for more information on laboratory and chemical.

Use cautious judgment when leaving unattended operations: 
Post signs to communicate appropriate warnings and precautions
Anticipate potential equipment and facility failures.
Provide containment for release of hazardous chemicals.

Do:
Wash your hands frequently to minimize chemical exposure through ingestion and direct contact with the skin.
Always wash hands before eating, drinking, smoking, or applying cosmetics.
Don't:
Use mouth suction for pipetting or siphoning。
Consume or store food or beverages or apply cosmetics in laboratories (including refrigerators and cold rooms) or in chemical storage areas
LABELING
Label all chemical containers with the identity of the contents.
Do not use abbreviations or acronyms. Include hazard warning and chemical concentration information.
TRANSPORTING
Use appropriate safety carriers (secondary containment) when transporting chemicals, either inside or outside of the building.

UNDERSTANDING HAZARDS
Know the hazards of the chemicals you are working with.Prior to using a chemical with which you are unfamiliar, consult the Safety Data Sheet (SDS) or other appropriate references 
Assume that unknown materials are toxic, and that a mixture is more toxic than its most toxic compound.
Minimize exposure to all chemicals, regardless of toxicity on their familiarity. Most laboratory chemicals have not been fully characterized with respect to their toxicity. It is prudent to implement procedures that will minimize the likelihood of exposure Skin contact should always be avoided. Avoid inhalation of chemicals and never "sniff" to

LAB CLEANLINESS
Keep work areas clean and uncluttered. Clean up work areas on completion of an operation or at the end of the day.
COLD AND WARM ROOMS
As most controlled temperature rooms (i.e. cold or warm rooms).lack mechanical exhaust (100% recirculated air), storage and use of toxic substances, flammable solvents, corrosive acids, asphyxiants (such as nitrogen and carbon dioxide), and open flames (e.g. Bunsen burners) is strictly prohibited.
