The term insecure laboratory procedures in the definition of the bio-hazard presented in the educational module refers to the "safe pipetting and other work done".
Explanation:
The "insecure laboratory procedure" tells us about the "safe pipetting and miscellaneous work practices" in the bio-hazard risk management as any mistake or wrong application may lead to some wrong chemical reaction which will cause huge damage or any side effect. Hence, safe pipetting or safe handling while working with bio hazards are necessary. Proper disposal, proper disinfectant and proper clean up are necessary. Proper care should be taken to avoid the contact of chemicals during pipetting.
