61. What is the maximum time allowed after cleaning with water as last rinse?
Equipment should not be left with water it after cleaning. The last step of the cleaning procedures involve drying with solvent or flushing with nitrogen, thus ensuring that there is no opportunity for microbial growth.62. What is the efficiency of the High Efficiency Particulate Air (HEPA) filter?
This type of air filter can remove at least 99.97% particles in air up to 0.3μm in diameter.63. What is the micron size of HEPA filter?
The micron size of HEPA filter is 0.3μm[ads id="ads1"]
64. Do you have any idea about schematic diagram of HVAC system?
65. If two different products are manufacturing in two modules of one production block, then will you accept the common air handling unit for both pharma area? Write “Yes” or “No” with reason?
No, because of cross-contamination (if re-circulation of return air)Yes, if 100% of fresh air is circulated through the respective area.
