The basic regulatory requirement is to provide pharmaceutical products of highest quality to the patients. A cleaning problem can have various consequences to health, economics, environment and regulatory approvals. Absence of good cleaning, leads to contaminated drugs, which pose risks for patients as well as manufacturing personnel.

Regulatory risk includes possible removal of authorization. Economical risk involves production delays and stock shortages or losses but also manifest as public relations problems for a company.

There are four main cleaning processes used in regulated environments.  These include:

  • Cleaning-in Place (CIP)
  • Cleaning-out-of-place (COP)
  • Manual Cleaning
  • Immersion Cleaning

So whats the difference between all of these cleaning techniques?

Cleaning In Place (CIP)

Cleaning in place can be described as the cleaning of equipment and vessels at the same place without movement of them to a different place. The cleaning agents can be transferred to the vessel or equipment types either thorough fixed piping or flexible hoses.

The CIP process can consist of the following elements:

  • Supply pump
  • Return pump
  • Heat exchanger with Black/Plant steam supply
  • Chemical tanks i.e Acid, Alkali tanks
  • Supply Pressure gauge or transmitter
  • Supply temperature sensors
  • Conductivity meter with sensor

Cleaning Out of Place (COP)

Cleaning Out of Place is defined as a method of cleaning equipment items by removing them from their operational area and taking them to a designated cleaning station for cleaning. It requires dismantling an apparatus, washing it in a central washing area using an automated system, and checking it at reassembly.

Manual Cleaning

Manual cleaning is the universal practise among the pharma and biopharma industries. The design, configuration and construction of equipment or the whole equipment which necessities the manual cleaning for the piece of equipment. The efficiency of the manual cleaning accomplished by training the cleaning operators, ensuring exact method of cleaning in the manual cleaning SOP, validating the method from different operators and verifying the procedure with interval of time.

The manual cleaning is dependent on,

  • Concentration of detergent used
  • Temperature of washing liquid

Immersion Cleaning

This is the type of cleaning in which the parts to be cleaned are placed in the cleaning solutions to come in contact with the entire surface of the parts.

Immersion cleaning is preferred for parts that must be placed in baskets and for processes requiring a long soaking time because of the type of contamination to be removed or the shape of the parts to be cleaned.
It is the most effective method, even if not the fastest one, and can be used with any type of cleaner for any process, heated or at room temperature. Immersion washers can be portable or stationary; single or multi-compartment; and are available with a variety of options, controls and valve configurations including CIP capability.

The important aspects during design of immersion washer should be

  • To minimize cycle time
  • Lower chemical usage
  • Reduce water and utility costs

Performance for immersion cleaning can be improved by moving the parts within the liquid or with agitation of the liquid, mechanically or with the addition of ultrasonic energy.

    Dear Sir,
    PLease give me a clarity on the Cleaning validation topic.

    In cleaning validation for each equipment cleaning result (Rinse/Swab) will receive upon cleaning sample analysis, for suppose the train of equipments are 10 and the Total cleaning sample result of all 10 equipments are 80 ppm (The sum of all equipment cleaning result). Is it meeting the APIC guideline requirement? Please brief me.
    Thanks in advance…….
    Sincerly

    does a clean hold time need to be defined for COP items in vaccine mfg?

The Four Phases of Conducting a Laboratory Investigation [Video]

The process which will be described here is based on the process discussed in the MHRA’s guidance on Out of Specifications Investigation.

When an out of specification, atypical or suspect result is obtained, it is particularly important that all solutions and reagents associated with the test are retained, as this will greatly assist the investigation.

The MHRA advocate laboratory investigations should proceed in four phases as follows:

Phase I(a)

Phase I (a) consists of a preliminary review, by the analyst, to determine whether there has been a clear and obvious error or event that caused the OOS, atypical or suspect result.

Phase I(b)

Phase I (b) occurs after phase 1(a) has failed to identify a clear and obvious cause. This is a more detailed investigation by the analyst and supervisor to identify a laboratory assignable cause.

Phase II

Phase II occurs after the phase I investigation has failed to identify a laboratory assignable cause for the OOS, atypical or suspect result and are driven by written and approved instructions in order to test particular hypothesis.

Phase III

In Phase III all the information obtained during Phases I and II of the laboratory investigation, and any manufacturing investigation, is reviewed and assessed, and a decision is made on the disposition of the batch
