5.1.22 TERMINAL STERILIZATION

a. Process whereby product is sterilized within its sterile barrier system.



5.2 Classification Number: 2.08 


                                            Cn 10N x [0.1/D]

Cn represents the maximum permitted concentration (in particle/m3 of air) of airborne particles that are equal to or larger than the considered particle size; Cn is rounded to the nearest whole number

N is the ISO classification number, which shall not exceed the value of 9. Intermediate ISO classification numbers may be specified; with 0.1 the smallest permitted increment of N

D is the considered particle size in μm
0.1    is a constant with a dimension of μm

5.3 Categories of sterile products


a Those that can be sterilized in final container (terminally sterilized)
b Those that cannot be terminally sterilized and must be aseptically prepared 

5.4     Aseptic Process


A Simple process flow for aseptically processed products.

5.6 Clean Room Grading and Classification

5.6.1 Four grades of clean areas:
a. Grade D (equivalent to Class 100,000, ISO 8):
Clean area for carrying out less critical stages in manufacture of aseptically
prepared products e.g., handling of components after washing.
b. Grade C (equivalent to Class 10,000, ISO 7):
Clean area for carrying out less critical stages in manufacture of aseptically
prepared products e.g. preparation of solutions to be filtered.
c. Grade B (equivalent to Class 100, ISO 5):
Background environment for Grade A zone, e.g.,cleanroom in which laminar
flow workstation is housed
d. Grade A (equivalent to Class 100 (US Federal Standard 209E), ISO 5
(ISO 14644-1):

• Local zone for high risk operations e.g., product filling, stopper bowls,
open vials, handling sterile materials, aseptic connections, transfer of partially
stoppered containers to be lyophilized.

• Conditions usually provided by laminar air flow workstation.
5.6.2 Each grade of clean room has specifications for viable and non-viable
particles.
5.6.3 Non-viable particles are defined by the air classification
5.6.4 DIFFERENTIAL PRESSURES
a. Positive pressure differential of 10-15 Pascal should be maintained between
adjacent rooms of different classification (with door closed). A differential air
pressure of 0.04 to 0.06 inches water gage is recommended between spaces.
b. Most critical area should have the highest pressure
c. Pressures should be continuously monitored and frequently recorded.
d. Any deviations should be investigated and effect on environmental quality
determined
5.6.4 Ambient temperature and humidity should not be uncomfortably high (could
cause operators to generate particles).
5.6.5 AIRFLOW VELOCITY
a. Laminar airflow workstation air speed of approx. 0.45m/s ± 20% at working
position (guidance value)
5.6.6 CLOTHING OF APPROPRIATE QUALITY: a. Grade D • hair, beard, moustache covered • protective clothing and shoes b. Grade C • hair, beard, moustache covered • single or 2-piece suit (covering wrists, high neck), shoes/overshoes • no fibres/particles to be shed c. Grade A and B • headgear, beard and moustache covered, masks, glovesnot shedding fibres,
and retain particles shed by operators • Outdoor clothing not in change rooms leading to Grade B and C rooms • Change at every working session, or once a day (if supportive data) • Change gloves and masks at every working session • Frequent disinfection of gloves during operations • Washing of garments – separate laundry facility • No damage, and according to validated procedures (washing and sterilization) • Regular microbiological monitoring of operators

5.8 CLEANING PROCEDURE OF STERILE AREA

5.8.1 Cleaning Procedure of Grade A Area
a. At the end of the day’s operation, promptly remove all unwanted material
from the sterile area. b. Machine parts that are directly contacts with products and can be autoclaved,
are washed with water for injection and are double raped with parachute bags and
then autoclave it. c. Laminar Air Flow Hood Curtain are wiped with lint free wipe and moped with
70 % IPA. Moping is done from upper side to lower side with wipe folded and
other side of wipe is used. Wiping is unidirectional. d. Machine is wiped from upper side to lower side and is unidirectional. e. Machine bench is wiped from machine to outer side and unidirectional with
lint free wipe. f. 70 % IPA solution spray should be done interval. g. After one week, disinfectant is changed with Proceine 40. Rotation of
disinfectant is necessary. h. Proceine 40 • Proceine 40 is concentrated germicide solution of alkyl-amino-alkyl-glycines. • Add contents of sachet to water for injection. • Mix in order to homogenize. • Apply by hand spray, disposable wiper, and mop or by immersion in order
to wet down all surfaces. • Allow contact time of 5 minutes. • There is generally no need to rinse after application. i. Q’BAC • Active ingredient in Q’ BAC is Triclosan 0.2 % w/w. • For general cleaning, dilute up to 1:1200 parts of hand water (5ml per
5 liters, 1 tsp per 5 ltr). • Mop or wipe the surface with it. • After use rinse and dry hands. For prolonged use it is advisable to wear
rubber gloves. j. Dettol • Active ingredient in Dettol is Chlorxylenol. • Add 200 ml in 5 Liters of Water for injection. • Mop or wipe the surface with it 5.8.2 Cleaning Procedure of Grade B Area a. At the end of the day’s operation, promptly remove all unwanted material
from the sterile area. b. Cleans the ducts and roof with lint free mop. c. Mop the walls and glass window and doors in such a way that moping should
be unidirectional and from upper side to lower side. d. Then mop the floor in such a way that mopping should be unidirectional and
from machine to door side. e. Use disinfectant as mention in Grade A area. 5.8.3 Cleaning Procedure of Grade C and D. a. Mop these areas with Dettol and spray with IPA 70 %. b. Clean the roof first and ducts. c. Mop the walls in such a way from upper side to lower side. d. Moping should be unidirectional and to door side.

5.9 PRECAUTIONS

5.9.1     Follow entry and exit procedure in critical areas. 5.9.2     Follow gowning and de-gowning procedure. 5.9.3     Moping and cleaning should unidirectional. 5.9.4     Moping should be from upper side to lower side. 5.9.5     Moping should be from machine side to door side.
