ISO 8 Monitoring HVAC GMP Clean Room In Pharmaceutical Industry
Pharmaceutical packaging GMP cleanroom
Environmental control requirements
(1) Provide the air purification level required for production. The
number of air dust particles and live microorganisms in the
purification process of the packaging workshop should be regularly
detected and recorded. The static pressure difference between the
packaging workshops with different grades should be kept within the
specified values.
(2) The temperature and relative humidity shall be compatible with
the requirements of the production process.
(3) The production area of penicillins, highly sensitizing and
anti-tumor drugs should be provided with an independent
air-conditioning system, and the exhaust gas should be purified.
(4) An effective dust-collecting device should be provided for the
room where dust is generated to prevent cross-contamination of
dust.
(5) For auxiliary production rooms such as warehousing, the
ventilation facilities and temperature and humidity should be
compatible with the production and packaging requirements of the
drug.
Cleanliness zone and number of air changes:
(1)The clean room should strictly control the air cleanliness, as
well as the ambient temperature, humidity, fresh air volume and
pressure difference etc.
The air cleanliness of pharmaceutical production and packaging
workshop is divided into 4 grades .
class 100 , 10,000 ,100,000 and 300,000.
To determine the number of air changes in the clean room, it is
necessary to compare the various air volumes and take the maximum
value.
In practice, class100 air exchanges is 300-400 times/h,
Class 10,000 air exchanges is 25-35 times/h,
Class 100,000 air exchanges is 15-20 times/h.
(2) The specific cleanliness class in the production and packaging
environment of pharmaceuticals shall be in accordance with the
national standard for purification.
(3) Determination of other environmental parameters of the
purification engineering of the packaging workshop.
(4) Packaging workshop purification engineering temperature and
humidity Clean room temperature and relative humidity should
conform to the pharmaceutical production process.
Temperature
Class 100 and 10,000 20~23 ℃(summer)
100,000 and 300,000 24 ~26℃, and the general area is 26 ~27℃.
Class 100 and 10,000 are sterile rooms.
Relative humidity:
45%- 50% moisture-absorbing drugs (summer),
50% -55% solid preparations such as tablets,
55%- 5% water needles and oral liquids.
clean room pressure
The clean room pressure to maintain indoor cleanliness needs to
maintain a positive indoor pressure.
The clean room for the production of dust, harmful substances, and
production of penicillin-based strong allergenic drugs must prevent
the inflow of external pollution and the outflow of internal air.
Therefore, the room must maintain a positive pressure and maintain
a relative negative pressure between adjacent rooms or areas.
The static pressure of different cleanliness rooms is greater than
5Pa, and the static pressure difference between clean room and
outdoor atmosphere is greater than 10Pa.
