Contamination Control Strategies for Manufacturing Area

Contamination Control for Pharmaceutical Manufacturing is an essential factor in the overall success of a pharmaceutical product.
Contamination is a very serious issue in pharmaceutical manufacturing especially in sterile manufacturing. It is important to control the contamination in the pharmaceutical manufacturing area to protect the product. There are many ways of contamination so there are different strategies to control it. This article provides some strategies to control contamination in pharmaceutical production.

Pharmaceutical manufacturing areas may have different types of equipment and contaminations. Contamination control is the most important aspect of pharmaceutical manufacturing. There is a variety of sources of contamination such as environment, employees and material.

The strategies for contamination control depend upon the type of contamination and the environmental conditions of the area. In general, there are four main types of contamination strategies. These are prevention, detection, contaminant and remediation. Prevention of contamination can be done by training the employees on dos and don’ts in sterile areas and cleaning procedures. Detection of contamination also plays an important to control it by environmental monitoring at regular intervals. Contaminant is the isolation of contaminated areas or materials by using an airlock system or any other way. Remediation is the removal of contamination from the contaminated area or equipment by cleaning or sanitization.

Contamination Control Systems in Pharmaceutical Manufacturing

Pharmaceutical manufacturing requires effective contamination control systems because it is the most regulated industry and requires the safety and efficacy of the products. Pharmaceutical products are manufactured in controlled and sterile environments in order to produce safe and effective products.

There are a number of contamination control methods used by the companies. Some of the common methods are:

Installation of Air Filters: Particulate matter, bacteria, fungi and viruses are removed from the air by the filters called HEPA filters. These filters are installed in the air handling units to supply the contamination-free air in the manufacturing area. This method helps to minimize the microbial contamination in the area.

Use of Barriers: Barriers in the form of tanks or filters are used to control the contamination between two areas. Pass boxes and airlocks are the widely used barrier systems in the pharmaceutical industry.

Use of Disinfectants: Disinfectants are very useful to control and eliminate the contamination from floor, equipment and air. Cleaning the floor using disinfectants is very effective in contamination control. Fogging and spraying the disinfectant is useful for air decontamination.

How does a Good Contamination Control System Look like?

An ideal contamination control system must be effective to control the contamination and should safeguard the product as well as the personnel working in the area. A good contamination control system should have four components.

1. Prevention: Prevention is the method used to avoid the creation of contamination means to remove the source of contamination.

2. Detection: Detection is the identification of the contamination by using the appropriate ways as applicable.

3. Cleanup: Cleanup is to remove the contamination wherever it is detected by the use of appropriate methods by cleaning, sanitization or decontamination.

4. Mitigation: Mitigation is the use of preventive measures to ensure that the same contamination event will not happen in the future.

It is not an easy task to maintain the pharmaceutical manufacturing area. It is very difficult to produce a contamination-free product. This article will help to maintain the area by controlling the contamination using useful contamination control strategies. The most effective way to control the contamination is to prevent the contamination into the facility, so focus on protecting the area from entry of contamination.
