Cleaning / Mopping & Fumigation in Microbiological Lab







Cleaning / Mopping & Fumigation in Microbiological Lab


1.     Purpose:-

1.1.       This procedure is developed to ensure the cleaning of area from microbes & non-viable particles.

2.     Scope:-

2.1.       This Procedure is followed for preparation of “Sterile Area” of liquid & dry powder Injectable sections.

3.     HSE Statement:-                |                 

3.1.      Follow the following instructions to perform cleaning and mopping in a safe manner.
§   Wear mask & gloves before preparing strong germicidal solutions.
§   Only trained and knowledgeable persons perform cleaning and mopping.
§   All work is performed in accordance with applicable regulatory requirements.
§   Report any job related injuries or illnesses, questions on health and safety, or any unsafe or unhealthy working conditions to supervisor.
§   Personal protective equipment necessary to perform cleaning and mopping in a safe manner.

4.     Responsibilities:-                |

Ø  Officer QC (Microbiologist) is responsible to expose media plates and to conduct the swab test.

5.     Materials:-                          |

                    i.                 SS Bucket
                  ii.                 SS Cleaning Roller

6.     Definition:-

6.1.   Cleaning

§   Cleaning is the process which is use to free the area from marks, pollutants and any remaining residues of previous batch.

6.2.   Mopping

§   Mopping is the process which can be done by the aid of antiseptic solution of different recommended percentages to clear the area from viable & non viable microorganism.


6.3.   Fumigation

§   Fumigation is the process which is used for the killing of microorganisms.

6.4.   Aseptic Area

§   An Area which can be clear from microbial & Particle contamination.


6.5.   Microbe

§   A microbe is a microscopic organism, such as a bacterium, virus or parasite. Microbes are so small that you need to use a microscope and special staining techniques to see them.

6.6.   Viable & Nonviable Particles
§   A viable particle contains one or more living microorganisms and can affect the sterility of the CSP. Viable particles generally range from 0.2micron to 30micron in size. Bacteria need a means to travel and inoculate the CSPs; their vectors can include bare or gloved hands and particles.
§   A nonviable particle does not contain a living microorganism, but acts as transportation for viable particles. Examples of nonviable particles can include metal, rust, dust, dirt, pollen, fibers, cloth, and chemical compounds found in makeup, including silicone, magnesium, sodium, potassium, and chloride. These particles can be introduced through employee movement, cleanroom garb or employee clothing, and the move- ment of products.
