Introduction
•All utilities that could impact on product
quality should be qualified and appropriately
monitored and action should be taken when
limits are exceeded.
•There are different type of utilities in the
pharmaceutical product manufacturing
2

VALIDATION
To prove the performance of processes or
systems under all conditions expected to be
encountered during future operations.
Validation involves proving-
1. Engineering design
2.Operating procedures and acceptable
ranges for control parameters
3. Maintenance procedures to accomplish it

 High-quality water is essential for the
manufacturing of pharmaceuticals. Water is the
most commonly used raw material in
pharmaceutical manufacturing.
 Water is directly or indirectly used in the
pharmaceutical manufacturing such as a major
component in injectable products and in cleaning
of manufacturing equipment.
Water is thus an important raw material in
GMP and in validating the manufacturing process.

• Phase 3 (verifying long term control)
QUALIFICATION PHASES
7

l phase)
• A further test period of 2-4 weeks – further
intensive monitoring of the system
• Utilization of all the SOPs after the satisfactory
completion of phase 1.

Types of steam system in pharmaceutical industries:
1.House steam-
 contains steam generator and
distribution system made of iron or
steel.
 Constructed with rusting material.
 This system is usually treated with
various substances like amines,
hydrazine or other boiler additives
to arrest corrosion.
2. Clean steam-
 It established when steam is
used for directly treating the
product or product contact
surfaces.
 Constructed with non-rusting
material. E,g. stainless steel.
 This system use either purified
or distilled water as feed water.

specifications and can be produced in quantities
required. 15

 Test all the use points of the system for
adequate supply of steam under maximum load
or other production condition.
 Quality of steam should be tested at all the use
points.
 Use point should also be tested to find out that
excess condensate is not present under
operating conditions.

Compressed Air system
 2 types of compressed air system are used in the
pharmaceutical industry.
1. Conventional oil lubricated compressors for
operating instruments and machinery where no
contact with product or the environment, where
product is being mfg. is involved.
2. An oil free compressed air system used in clean
room areas.
 It contains mainly compressor, dryer, storage tank and
distribution system. 18

INSTALLATION QUALIFICATION
1. Oil free compressor
 Check specification on purchase order and actual
delivery specification
 Verify that no oil or other lubricant is used in the
compressor
 Check that all required utility requirements have been
met and connected properly
 Check whether pre-start up procedures were performed
 Check whether all critical instruments have been
calibrated
 Document above all

 Confirm the material of construction and design
parameter specified by the company
 Compare the drawing of the system with “as-
built” drawing to show whether any modification
have been made and note the modifications.
 Pressure test the system to confirm its integrity
and record the result
 Examine the cleaning procedures after
installation
21

OPERATIONAL QUALIFICATION
 Check all the use points for the tests mentioned below and
record the results.
 Identity
 Nonviable particle count
 Microbial count
 Check several worst-case locations for purity.
 Test all instrument and alarms for their operational status and
record.
 Test the compressor output for hydrocarbons. 22

PERFORMANCE QUALIFICATION
 It consist of completing the documentation from various
steps mentioned above and repeating operational testing
as specified in the validation protocol.
 In case of the system PQ can be considered as validation.
23

Heating Ventilation and Air Conditioning
system(HVAC)
HVAC systems can have an impact on product quality
It can provide comfortable conditions for operators
The impact on premises and prevention of
contamination and cross-contamination to be considered

VALIDATION PARAMETERS

NON-VIABLE PARTICLE COUNTS
 Equipment
 Optical Particle Counter .
 Air sample is drawn into the instrument & passed through
light scattering device. The signal that this generates is
electronically processed to display particle counts at different
size ranges.
 Acceptance criteria:
The particle concentration under the dynamic
condition should not more than 100 particle of
0.5µm and larger per cubic meter (for class 100
area)
27

PRESSURE DIFFERENTIALS
- Correct degree of overpressure can be maintained
relative to the adjacent areas of lower classification to
ensure that air moves from clean areas to less clean
areas.
- It is calculated by making use of the manometer
attached at the walls of the adjacent area.
- The pressure difference is generally kept between 5
and 20 mmHg pressure.
28

AIRFLOW VELOCITY
 Equipment :- Anemometer
 Reading should be taken 10cm from the surface of filter.
 Record velocity reading from all the four corners and the
Centre of the filter surface.
 Repeat twice at each location
 For Grade A laminar flow workstations, the air flow rates
shall be 0.3 meter per second + 20% (for vertical flows)
and 0.45 + 20% (for Horizontal flows)
 Solution : Alteration of fan speed or HEPA filter
replacement
29

HEPA filter integrity test (DOP test)
 Purpose :
To confirm that no damage to filter, seals and no leakage of
particles.
 Equipment :
1. Aerosol generator
2. Photometer
 Acceptance criteria:
An unacceptable leak is defined as a penetration of
0.03% or more of particle, 0.3µm and larger than the
reference calibration curve for 99.97% efficient filter
30

Recovery test
The recovery of temperature and humidity is
checked. For this, the humidity and temperature are
checked at the off position of the HVAC system.
Then the humidity is increased to 75% and
temperature to 400°C and again the temperature and
humidity are measured after switching on the HVAC
system, and the time required to stabilize the
temperature and humidity is noted.
31

MICROBIOLOGICAL TESTS
Solid growth media (e.g. settle and contact plates)
Soybean Casein Digest Agar medium can be used for
both Bacteria & Fungi tested.
The recommended size of solid media is 90 mm in
diameter (for settle plates)
55 mm for contact plates.
32

Air flow or smoke pattern
For the evaluation of this parameter, a titanium
tetrachloride stick is taken and burnt and the burning stick
is placed in front of the AHU. The distribution of smoke
is observed.
It should be uniform.
Particle count
A particle counter is used to conduct the test. Particle
count is taken before the operation as well as during the
working condition.
The particle count should be within the range as per the
standards of Grade A, B, C, and D area.
