How frequently must all surfaces in ISO 7 and 8 areas be cleaned?

The correct answer is that all surfaces in ISO 7 and 8 areas must be cleaned daily. This requirement is established to maintain the appropriate level of cleanliness and to minimize the risk of contamination in controlled environments where sterile compounding occurs. ISO 7 and 8 areas are classified based on their cleanliness levels, and maintaining a clean environment is essential for ensuring the safety and efficacy of compounded sterile products.

Daily cleaning helps to control dust, particulate matter, and microbial contamination, which is crucial in protecting patient health and maintaining compliance with regulatory standards. The adherence to rigorous cleaning protocols is key in upholding the integrity of the processes that take place in these areas, as even slight deviations can lead to increased risks of infections or compromised medication quality.

In contrast, options suggesting less frequent cleaning (weekly, bi-weekly, or monthly) do not align with the stringent requirements expected in such critical environments. Regular cleaning is vital, and a daily routine is the minimum standard to ensure safety and compliance in pharmaceutical practices.
