As with every successful endeavor, working in the laboratory poses its own set of dangers, as such special care and precautions needs to be taken to ensure a safe working environment. Some precautions taken include.

-Lab coats should always be worn while in the lab.
-Gloves should always be worn when handling corrosive and toxic chemicals such as Ninhydrin, commassie blue, sodium hydroxide pellets etc.
-Poisonous and toxic liquids such as phenol, conc. Acids, acrylamide etc must never be mouth pipetted; they should be delivered with the aid of a micropipette or burette.
-Discarded culture  media should be soaked in jik and soap solution for at least 30mins before washing with gloved hands.
-Bunsen burner flames should not be used near flammable liquids such as Acetone petroleum ether etc.
-All electrical appliances should be disconnected from their power source before leaving the lab.
-Eating should be forbidden in the lab.
-Before closing for the day, hands are washed with plenty of water.

Other laboratory practices includes
   
-Ensuring that all clean laboratory waves are rinsed with distilled water and are properly dry before storage.
-Ensuring that all prepared reagents and weighed chemical are well labeled.
-Accurate recording of all parameters used on the course of the experiment such as weight, volumes; immediately after that process.
-Working with the molecular weight of chemical that are state on the containers rather than the theoretical molecular weight.
