Abstract: Background and aims: Nowadays, cleanrooms have become impartible parts of an industry with sensitive products. Sources of contamination in cleanrooms are impaired performance and quality sensitive products in the cleanrooms .The aim of this study was to evaluate the efficiency of HEPA filter and check the concentration and number of airborne particles in cleanrooms for pharmaceutic...
متن کاملDifferences in the correlation between microbiological air sampling and particle counting in operating theatres and hospital cleanrooms
Introduction / objectives The process of environmental monitoring in cleanrooms of clinical pharmacy and operating theatres is difficult, the measurement of bio burden is time consuming and the result is available several days after the operation. This study examines the correlation between the number of airborne bacteria and particles in operating theatres and cytostatic compounding cleanrooms...
متن کاملDecay of airborne contamination and ventilation effectiveness of cleanrooms
This article reports an investigation into the ability of the air supply in non-unidirectional cleanrooms to aid recovery from episodes of airborne contamination, and minimise airborne contamination at important locations. The ISO 14644-3 (2005) recovery test, which measures the rate of decay of test particles, was assessed and a reinterpretation of the test results suggested. This allowed air ...
متن کاملThe importance of cleanrooms for the treatment of haemato-oncological patients
The main purpose of cleanrooms in health care centres is to prevent hospital infections or leakage of a highly infectious agent (the source of haemorrhagic fevers, SARS, etc.) into the ambient environment and subsequently possibly threatening other individuals. Patients with haematological malignancies or after autologous or allogeneic haematopoietic stem cell transplantation (HSCT) rank among ...
متن کاملToward Green Systems for Cleanrooms: Energy Efficient Fan-filter Units
The paper presents results of laboratory-measured performance of fan-filter units (FFUs) used for cleanrooms. A total of twenty FFUs collected from the market were tested, including thirteen 1220 mm x 610 mm (or 4 ft x 2 ft) units and seven 1220 mm x 1220 mm (or 4 ft x 4 ft) units. The paper concludes that there are wide variations in FFUs’ energy performance, and that there are opportunities i...
