VP/MSC/001/R0
Introduction: Pharmaceutical rules and specifications are often contains very precise but also generally formulated requirements of air conditioning technology, such as “temperature, humidity and ventilation of premises should be adequate”. This generally formulated requirement is partially substantiated in the supplementary guidelines of the EU GMP Guideline for the manufacture of sterile products.
Two basic types are distinguished by the terms of Room Ventilation Technology and Process Air Conditioning Technology. Both types are found and required in the pharmaceutical manufacturing sites. The essential task of a ventilation system is to guarantee that the desired room conditions, such as temperature, humidity and cleanliness. In contrast, the process air systems must guarantee the required process parameters.
General: The HVAC system plays an important role in product, personnel, environment, instrument and machine protection. This can be presented as clean environment, removal of hazard contaminant and provide a suitable temperature and humidity control within acceptable noise level by providing clean environment.
HVAC utility is designed to control the level of viable and non-viable particulate exposure that a drug or medicinal device might receive in addition to regulating temperature and relative humidity conditions. HVAC utility is qualified to demonstrate operating conditions of the area. The areas serviced by the HVAC utility are classified based on viable and non-viable particulate levels during static operating conditions and dynamic operating conditions.

System boundaries: The physical boundaries are defined as follows: 5.1 Source of air handling units (AHUs) and air conditioning units (ACUs) including other forms of air pretreatment (e.g., heating/cooling, dehumidification/ humidification), Attachment No.2 – Diagram for Sterile Area. 5.1.1
AHUs require externally supplied heating and cooling sources such as steam, hot water, or chilled water.
5.1.2
ACUs are self-contained with respect to heating and cooling, and generally employ a refrigeration-based heat pump. They may be reversible and both heat and cool the supply airflow.
5.1.3
AHUs, ACUs, and associated ductwork, which supply air to critical and controlled areas/rooms, are included, while AHUs, ACUs, and related ductwork, which supply non-GMP; uncontrolled areas (e.g., offices, cafeterias) are not included.
5.2 Supply air and return air ductwork up to, but not including, grills inside rooms or areas. 5.3 Support utility interfaces (e.g., electrical connections at disconnect points) for heating/cooling water supplies, etc. 6.
Area Description (Sterile Area) 6.1 This area is defined to use only sterile oriented products for manufacturing. The aseptic process involves the handling of sterile components until they are sealed in their final containers. 6.2 Aseptic area is designed, constructed and engineered to comply with pharmaceutical compliance standards and to prevent microbial contamination. 6.3 The clean room for the aseptic area is classified according to the required characteristics of the environment. The “in-operation” and “at rest” states should be defined for each clean room or suites as mentioned in the below-mentioned grade: 6.3.1. Grade A: The local zone for high-risk operations includes aseptic filling zone, stopper bowls, open vials and making aseptic connections. This zone is equipped with laminar flow systems with homogenous air speed in a range of 0.36 to 0.54m/s. 6.3.2. Grade B: This is the background environment for grade A zone. 6.3.3. Grade C: Clean areas for carrying out less critical stages in the manufacture of sterile products. 6.3.4. Grade D: This area is unclassified, as it is meant for capping gowning room and black/grey change room. 6.3.5. The airborne particulate classification for these grades are given in the following table:

a. Particle measurement based on the use of a discrete airborne particle counter to measure the concentration of particles at designated sizes equal to or greater than the threshold stated. A continuous measurement system should be used for monitoring the concentration of particles in the grade A zone, and is recommended for the surrounding grade B areas also. For routine testing the total samples volume should not be less than 1 m3 for grade A and B areas and preferably also in grade C areas. b. The particulate conditions given in the table for the “at rest” state should be achieved after a short “Clean up” period of 15-20 minutes (guidance value) in an unmanned state after completion of operations. The particulate conditions for grade A “in operation” given in the table should be maintained in the zone immediately surrounding the product whenever the product or open container is exposed to the environment. It is accepted that it may not always be possible to demonstrate conformity with particulate standards at the point of fill or when filling is in progress, due to the generation of particles or droplets from the product itself. c. In order to reach the B, C an D air grades, the number of air changes should be related to the size of the room and the equipment and personnel present in the room. The air system should be provided with appropriate terminal filters such as HEPA for grades A, B and C. d. The guidance given for the maximum permitted number of particles in the “at rest” and “in operation” conditions correspond approximately to the cleanliness classes in the EN/ISO 14644-1 at a particle size of 0.5µm. e. These areas are expected to be completely free from particles of size greater than or equal to 5µm.
f. The requirements and limits are depending on the nature of the operations carried out.

Limits for the microbial contamination of surfaces in these cleanliness grades are generally tested with purchased nutrition agar contact plates with a diameter of 55 mm (corresponds to a surface area of 23.75 cm2). Therefore need to consider the specifications per cm2 and include them in standard operating procedures (SOPs). To be on the safe side, you can comply with the required limit for a contact area of > 23.75 cm2. Normally, specifications are provided per plate with a diameter of 55mm or per 25 cm2

For absolutely necessary interventions in cleanliness grade A, the hands covered by the gloves should be disinfected to ensure that the limit of <1 CFU/5 fingertips is not reached. However, since individual values of 1 and >1 cannot be excluded (<1 is an average value), in this case, the average value of the last ten quality controls should be used. This average value must be <1 CFU/5 fingertips (measure limit value/action limit). In the presence of correct personnel behavior and operational cycle, a bioburden on the finger tips of >3 CFU/5 fingertips is extremely rare. If operating procedures are not adhered to, the values are considerably higher, i.e., a value of 2 CFU/5 fingertips can be an indication of systematic failures and should be regarded as a warning sign. The alert limit could therefore be determined at 2 CFU/5 fingertips. 7.
Requirement for Materials and Equipment 7.1 Materials required are all the items, which will be routinely used to test air quality for particulates and microbial counts, the manual operations, humidity, airflow, make-up air etc. etc. 7.2 Following list of devices must be calibrated before they are used during the qualification plan. SOPs for each test method, the operation and calibrations of these equipment used, the data to be recorded and the criteria for acceptance must be prepared and approved before beginning the qualification plan.

Room/area differential pressures. vii.4.7. Test technician qualifications. viii. Air pattern Test (Airflow visualization) viii.1 It is important (Unidirectional flow area) that air flows through the critical area in a smooth pattern without disturbances or eddies which would prevent particulate matter from being swept out of the area by the airflow or cause less clean air to be brought into the cleaner area. viii.2 Air pattern testing shall be conducted in critical rooms/areas to demonstrate airflow patterns from HEPA through areas/levels of product exposure. viii.3 Air pattern testing shall also be designed to verify airflows from high-pressure areas (clean) towards lower pressure areas (less clean). viii.4 All air patterns shall be verified by visually observing airflow with smoke sticks, vapor generators, or other suitable means. viii.5 Air pattern testing must be recorded via videotaping. viii.6 Airflow pattern testing should be done in both static and dynamic conditions. viii.7 Influence of personnel on the airflow pattern during normal operations (sterile filling machine set-up, aseptic connection of sterile transfer lines and interventions) should be included in the studies. viii.8 An audit may be performed if the documentation for air pattern testing is available and complete.

ix.5 Measurement must be taken in the four corners and the approximate center of each room or area at a height of approximately 3feet from the floor. ix.6 Measurement must be performed at least once in each of three consecutive eighthour time periods. ix.7 Control system temperature and RH readings should be recorded for each room simultaneously with taking the independent measurements. ix.8 Available control system temperature and RH archives for the test period should be attached to the protocol. ix.9 Outside temperature and humidity should also be measured and recorded once for each set of measurements. ix.10 An audit may be performed if the documentation for Temperature and Relative humidity monitoring is available and complete. If documentation is found not be satisfactory then the “Test” procedure must be performed.
x. Clean room pressurization test (also differential pressures) x.1 To maintain air quality in critical and controlled areas, it is important that any airflow that occurs between adjacent areas, which have different classification levels, must be from the cleaner area to the less clean area (i.e. from a class 5 area to a class 8 area). This is accomplished by maintaining the air pressure in the cleaner area at a slightly higher level than an air pressure in the less clean area. x.2 Airflow direction (i.e. in some solid dosage facilities) is designed to create conditions that contain product and minimize cross contamination. This is accomplished by maintaining the air pressure in a common area at a slightly higher or lower level than the air pressure in the adjacent areas of different classifications or cleanliness level (same classification). x.3 Differential pressure/airflow directional testing shall be conducted to verify the ability of the HVAC system to maintain plant pressurization (positive and negative) between adjacent areas as per the design specifications. This monitoring should be performed routinely and action level should be established in the monitoring program. x.4 Differential pressure readings/measurements should be recorded using existing, (calibrated) installed system instrumentation. In the absence of such instrumentation, an independent calibrated ∆P gauge or inclined manometer with an appropriate range may be used. The recording of differential pressure measurements shall be conducted once a day for three (3) days in order to demonstrate stability. x.5 An audit may be performed if the documentation for the Differential Air Pressure and Direction Test is available and complete. If documentation is found not satisfactory then the “Test” procedure must be performed. x.6 ∆P between any room and the main corridor must be within the tabulated defined range, which ensures that the ∆P between two adjacent rooms, which have same/different classification levels, is not less than 12.5pa. The supply and return air volumes should conform with the range specified. Pressure differential between rooms should be maintained as indicated in the specifications

xiii. Control, Alarms and Interlocks. xiii.1 Alarms xiii.1.1. HVAC systems frequently incorporate safety features such as smoke alarms or noxious fume alarms. xiii.1.2. HVAC systems frequently include alarms for items such as room pressurization, temperature and relative humidity, which could, if out of specification (OOS), potentially have an adverse effect on product quality. xiii.1.3. Safety system features should be tested in order to ensure personnel and system safety. xiii.1.4. Critical alarms should be tested for proper operation to ensure that they are functional and will provide warning before any system, product quality, or personnel safety is compromised. xiii.1.5. HVAC system alarms are listed below: xiii.1.5.1. Smoke detector operation. xiii.1.5.2. Plenum pressure alarms xiii.1.5.3. Room door interlocks xiii.1.5.4. Filter ∆P alarms. xiii.1.5.5. Room pressure/∆P alarms xiii.1.5.6. Temperature alarms xiii.1.5.7. Humidity alarms. xiii.2 Interlocking: xiii.2.1. Interlocks may be mechanical or part of the electrical/mechanical control system. xiii.2.2. Some interlocks are not associated with loops and may serve to either act as preventive measures (turn the pump off before the tank is empty preventing pump cavitation) or to initiate an activity (an exhaust fan automatically starts when the supply fan is started). xiii.2.3. Interlock testing may be performed as part of normal sequence of operation testing or as a separate activity. xiii.2.4. Like sequence testing, interlock testing involves the forcing either through simulation or through ‘expected’ operating conditions of inputs and verifying that the interlock action operations as specified. xiii.2.5. Door interlocking (X door is opened when Y door is closed, similarly, Y door is opened when X door is closed) system creates to keep the area intact and prevent from the contamination.

15. Performance Qualification Performance Qualification is outlined below represents the quality testing performed in the OQ (i.e. viable) but expands the scope to include testing under dynamic conditions. The final and real challenge for the environment control system and HVAC system is represented by the process that must be executed within the areas it is serving. Upon determination of the new approved conditions, if needed, changes to the system are to be executed and revalidated before proceeding to the performance qualification. Performance Qualification (PQ) protocol No PQP\VD\01\R00 shall be generated; the following qualification tests will be included in the PQ protocol and protocol must be prepared according to SOP-VD-012. This section describes the various types of monitoring that would be performed to adequately qualify the operating environment for processing. i.
Performance Qualification must be performed on the facility in three different stages that are i.1 “As-built” (No equipment, no personnel). i.2 “At-rest” (equipment but no operations and no personnel) i.3 “Operational” (With personnel, equipment operations)
Consistent results must be obtained which should be within specified limits for 20consecutive working days for each of the three stages (as built, at rest and operation). ii.
Verification of Performance Qualification prerequisites ii.1 The success of the system to control the level of viable and non-viable particulate levels as well as its ability to regulate temperature and relative humidity conditions depends not only on the system performance, but on outside factors such as personnel training, room sanitization, and system maintenance. ii.2 Method for sanitization procedures, supporting utilities and personnel should be qualified/trained before the initiation of the PQ as well as procedures for sampling, operation and maintenance should be in place. ii.3 By having these prerequisites completed before the HVAC system PQ and environmental monitoring program, the success for PQ is greatly extended and it is much easier to isolate attributable causes in the event of PQ failure. ii.4 The prerequisites for the HVAC system PQ can be summarized below: ii.4.1. HVAC: IQ and OQ complete. ii.4.2. Utilities: IQ, OQ, PQ and including SOPs for compressed air and steam.

ii.4.3. Personnel: SOPs and training documentation for equipment operation, room sanitization gowning and environment monitoring. Training in pertinent SOP’s for HVAC & sterile area facility & all related operation and maintenance machines are completed and documented from all concern departments and persons ii.4.4. Standard Operating System (SOP) must be development and approved before performance qualification (PQ) tests are executed for following: a. Environmental Monitoring. b. System Operation c. System Maintenance. ii.5 All critical punch-list items from IQ and OQ must be cleared and resolved. iii.
Temperature – Humidity Control Test - Dynamic Condition iii.1 To demonstrate the ability of the HVAC system to control temperature and humidity during operating conditions. This test must be executed while the process or operation are simulated or executed. iii.2 The Temperature-humidity control test provides verification of temperature and humidity under dynamic conditions, as well as indicating that the system is capable of maintaining the design conditions. It also provides a good basis for determination of the general status of the system, for its malfunction can be used as diagnostic of the inadequate operation of the HVAC. iii.3 Seasonal conditions of temperature and humidity may vary with the system design and the amount of external non-conditioned air supplied to the airhandling units serving the controlled environment. Sporadically, seasonal variations can be simulated during validation conditions.
iv.
Differential Air Pressure and Direction Test – Dynamic Conditions iv.1 In order to maintain air quality in critical and controlled areas, it is important that any airflow that occurs between adjacent areas which have different classification levels must be from the cleaner area to the less clean area (i.e., from a Class 5 area to a Class 7area). This is accomplished by maintaining the air pressure in the cleaner area at a slightly higher level than the air pressure in the less clean area. iv.2
In s solid dosage facilities, airflow direction is designed to create conditions that contain product and minimize cross contamination. This is accomplished by maintaining the air pressure in the common area at a slightly higher level than the air pressure in the processing area.
iv.3 US guidelines require a differential pressure of 0.05” water column between rooms of different air cleanliness. EU guidelines require a differential pressure 10-15 Pascals.

iv.4 Differential Pressure/Airflow Directional Testing shall be conducted to verify the ability of the HVAC System to maintain plant pressurization positive between adjacent areas while in a normal operating condition (machinery in use and normal complement of operators present). This monitoring should be performed routinely and action levels should be established in the monitoring program per the requirements of ISO standard 14644-1 and 2. iv.5 Differential pressure readings/measurements should be recorded using existing, (calibrated) installed system instrumentation. In the absence of such instrumentation, an independent calibrated dP gauge or inclined manometer with an appropriate range may be used. The recording of differential pressure measurements shall be conducted once a day for three (20) working days in order to demonstrate stability. v.
Air Cleanliness Test v.1 Air Cleanliness test must be performed in order to determine that the complete as-built, operational facility meets the air cleanliness requirements specified in the user requirement specification. v.2 Airborne concentrations are measured with white light, laser, or condensation nuclei particle counters. v.3 Air cleanliness classification for controlled environments must be based on the concentration of particles of a specific size per unit of volume. v.4 Sampling location and sample size must be set cautiously. v.5 A sample should be taken at the fill point at a distance not exceeding 30cm (1ft3) from the point of exposure and a sample volume of 1ft3. v.6 The table demonstrates the limit and range of air quality for every parameters that are performed in accordance with standard establishment Parameters

viii.6 Limits: Controlled Areas: The EU guidelines require these areas to be Class C. Air in controlled areas is generally of acceptable particulate quality if it has a per-cubic-meter particle count of not more than 3,520,000 in a size range of 0.5 micron and larger (Class 8) when measured in the vicinity of the exposed articles during periods of activity. There is also a requirement to have less than 29,000 particles/m3 of 5.0 m and larger in the “in operation” state. To meet EU requirements both 0.5 and 5.0 m particle sizes must be counted. Critical Areas:
The EU guideline requires these areas to be Class A (corresponding to US Class 5 unidirectional flow), with the background of Class B. Air in the immediate proximity of exposed sterilized containers/closures and filling/closing operations is of acceptable particulate quality when it has a per-cubic-meter particle count of no more than 3,520 in a size range of 0.5 micron and larger (corresponds to US Class 5) when measured not more than one foot away from the work site, and upstream of the airflow, during filling/closing operations. It is accepted that sometimes conformity with particle counts may not be met at point of fill due to generation of particles or droplets from the product itself. Class B under dynamic conditions is of acceptable particulate quality when it has a per-cubic-meter particle count of no more than 352,000 of 0.5 micron and larger. The 5.0 m limits are 20 particles/m3 for Grade A and 2,900 particles/m3 for Grade B in operation.

(Media fills are understood to be synonymous to simulated product fills, broth trials, broth fills etc.). 23.17 Operational Qualification (OQ): The documented verification that the facilities, systems and equipment, as installed or modified, perform as intended throughout the anticipated operating ranges. 23.18 Performance Qualification (PQ): The documented verification that the facilities, systems and equipment, as connected together, can perform effectively and reproducibly, based on the approved process method and product specification. 23.19 Pre-determined acceptance criteria: The criteria assigned, before undertaking testing, to allow evaluation of test results to demonstrate compliance with a test phase of delivery requirement 23.20 Unidirectional flow: An airflow moving in a single direction, in a robust and uniform manner, and at sufficient speed to reproducibly sweep particles away from the critical processing or testing area. 23.21 Validation master plan: A document providing information on the company's validation work programme. It should define details of and timescales for the validation work to be performed. Responsibilities relating to the plan should be stated. 23.22 Validation protocol: A written plan stating how validation will be conducted and defining acceptance criteria. For example, the protocol for a manufacturing process identifies processing equipment, critical process parameters/operating ranges, product characteristics, sampling, test data to be collected, number of validation runs, and acceptable test results. 23.23 Validation report: Document reporting the validation activities, the validation data and the conclusions drawn. 24.
