When installed, it will contribute greatly to maintaining or increasing air cleanliness levels. SOP for Operation, Cleaning, and Monitoring of Bio-Safety Cabinet. Principle/ Working of Laminar flow hood The principle of laminar flow cabinet is based on the laminar flow of air through the cabinet. 5.5.10 Record the cleanliness of filter as shown in Annexure 6 What is the use of reverse laminar air flow? 5.19 Store person shall weigh one material at a time in double polybags by scoops on balance. This chart is intended for reference only. Laminar airflow is working through air moving at the same speed and in the same direction, with no or minimal cross-over of air streams. It is a dynamic barrier of HEPA-filtered unidirectional air flow to move particles away from the filling/closing area. Olga Elsmar Forum Sponsor O Olgamargarita If theresults are found to be within the specified limits, affix qualification status labels. 3. LAF systems are designed for use in conjunction with body exhaust suits to decrease bacterial and skin particle (squames) shedding from operative personnel into the air plenum [109].

Ability to measure the flow of high viscous liquid. 6.1 Record of AHU filter cleaning Annexure -1 The airflow movement should be from Supply filter Diffuser to the Return Air Grill / Riser and most Positive area to the Negative area. The line must operate in a clean room grade B or higher. Scanning shall be done at the rate of maximum 2 feet per minute. The major difference between laminar-flow chamber and biosafety cabinet is that air which comes out of the biosafety cabinet is filtered using HEPA filter (High Efficiency Particulate Air Filter), where in laminar-flow air blows out unfiltered so there is no protection for the laboratory worker. You can find HEPA filters in most air purifiers. This is why such filters are a critical feature in bigger cleanrooms. 4.7 Recovery Test: These test are executed on LAF work bench. Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction. CD: Compact disk, Annexure I Air Flow Test Purair FLOW and Purair PCR cabinets should be cleaned with 3%-6% hydrogen peroxide as it is more gentle on the polycarbonate construction. MB : Microbiology Mail us at: info@pharmastate.com 4.7.1 Recovery test is done to find out recovery time of the LAF, RLAF after stoppage or break down. 5.1.3 Mop the external surfaces with a clean dry lint-free cloth damped with potable water.

Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. During scanning percentage of the PAO penetration shown by photometer should be less than 0.001% through the filter media and should be zero through mounting joints. In a laminar flow hood the air is passed through a HEPA (High Efficiency Particulates Air) filter which removes all airborne contamination to maintain sterile conditions. The Particle count foreach minute is taken until the clean room condition is disturbed .i.e. The pre-filter of RLAF unit are cleaned and Magnehelic gauges are calibrated. Greenville, SC To lay down a procedure for performance qualification of LAF, RLAF and dynamic pass box. Cleanrooms in pharmaceutical industry maintain particulate-free air through the use of either HEPA or ULPA filters employing laminar or turbulent air flow principles. After 30 minutes switch OFF the UV and switch ON the Visible light. Ensure visually the cleanliness of the new filter. Validation Team Members and their Signatures, Quality Assurance Department Certification. The instrument used shall be linear aerosol photometer. Some operations, such as the manufacturing of non-sterile pharmaceuticals, do not automatically require a cleanroom, whereas sterile drugs necessarily do. Laminar Flow units are used to blow filtered air above areas requiring a sterile environment. HEPA is an acronym for High Efficiency Particulate Air or High Efficiency Particulate Arrestance. This acronym refers to a filter that is manufactured, tested and certified to meet Institute of Environmental Sciences and Technology (IEST) construction, performance and certification standards as currently published . 5.5.4 Personnel protective equipments like nose mask, safety goggles and rubber hand gloves shall be used. QC : Quality Control Cleaning of Laminar Air Flow (LAF) First of all, Turn OFF the switch of the Air Flow and UV of LAF unit (if ON). The environmental conditions for sterile processing are designed to maintain product sterility and are ISO 5 or Grade A classified, considering the following parameters: In accordance with these standards, Dara Pharma has developed a wide range of products for different environmental conditions.

Tasks and applications to do in a Grade A area: The Grade B cleanroom, in operation, is equivalent to an ISO 7 environment, while at rest, it corresponds to an ISO 5 cleanroom. Affix the "TO BE CLEANED" label duly filled and signed. The air flow in the RLAF system should be re-circulated. Majorly used for mixed airflow stream to control the hazardous emission of dust powder during dispensing or sampling process. Industrial HEPA filters or High-Efficiency Particle Air filters are an essential part of the pharmaceutical and healthcare industries, where sterile environments are mandatory. Check the reading of magnehelic gauges. Then clean properly the working chamber from ceiling, followed by side glass and then the platform of the chamber with 70% IPA. The following tests shall be carried out by for PQ of LAF: V1 V2, V3 V4, Where, FPM is Feet per minute,CFM is Cubic Feet per minute, Air velocity should be 90 20 feet/minute. LAF - Laminar Air Flow Aseptic pharmaceutical . At rest, the number of particles allowed for each cubic meter is 352,000, while the number is 3,520, 000 in operation. This is achieved by total removal of air borne droplet nuclei and dust-borne bacteria by unidirectional oriented streamlines of clean air at velocities designed to flush contaminating particulates. What happens if we use LAF ? Reverse laminar air flow operates on the principle of providing containment of contaminated air by air movement. These criteria are intended to reduce the risk of microbiological, particle, and pyrogen contamination. very thankfuly for your comments. Lux level should not be less than 150 lux.

For any Feedback or suggestion mail at: info@pharmastate.com 1.0 Objective Filter leakage test (PAO test) Six Monthly. 6.0 PROCEDURE FOR FILTER CLEANING: Prefilters capture airborne contaminants in the rear of the room or hood, and the velocity of the air entering the filters is accelerated to reduce the number of particles that recirculate into the room. Laminar Air Flow (LAF) A laminar air flow system is a vital concept in the control of particulate contamination in a pharmaceutical Industry. Please, why does the RLAf have to be on for 15 minutes first? 4.3.1 Filter leakage test is performed to confirm that the filter system is properly installed andthat leaks have not developed during use. 4.4.6 Calculation of air flow supply And lastly, clean the work surface. 5.1 Frequency: The cleaning frequency of filter is as follows: What is the red colour fluid which is present in laminar air flow? 5.1.2 Clean the external surface of the RLAF with a vacuum cleaner. It is provided with HEPA filter, which prevents the airborne dusts by down draught technique. The key difference between laminar flow hoods and reverse laminar flow hoods is that the former protects items on the work surface while the latter protects operators.
