How often should all work surfaces and flooring of a clean room be sanitized?

• A. Weekly
• B. Every day
• C. Monthly
• D. Yearly

Answer: (B)

In a clean room, keeping contamination at bay requires regular, frequent sanitation of all work surfaces and flooring. Sanitation should occur daily to continuously minimize microbial load and particulates that can transfer to products or processes. Waiting longer allows contaminants to accumulate, increasing risk to product quality and aseptic conditions, which is why daily cleaning aligns with typical GMP/ISO cleanroom standards. Weekly, monthly, or yearly sanitization would be far too infrequent and not sufficient to maintain the required clean environment. Additional cleaning may be done before or after specific operations, but daily sanitation is the baseline practice.
