Q163 · Category D: Premises and Storage Requirements (Q151-Q200)
Establishing a compliant cleaning and disinfection procedure is fundamental to maintaining hygiene in the medicine storage environment. The procedure must be a written Standard Operating Procedure (SOP) and should include: 1. Scope of cleaning, covering all areas, including floors, walls, shelving and equipment. 2. Cleaning frequency, which may vary between areas—for example, daily cleaning of operational areas and weekly or monthly cleaning of high shelving. 3. Cleaning agents and disinfectants used, specifying the product name, concentration and method of use, and ensuring they will not contaminate medicines. 4. Cleaning tools, specifying dedicated tools (such as mops and cloths) and how they are to be cleaned and stored after use to prevent cross-contamination. 5. Cleaning methods, describing the operating steps in detail. 6. Record-keeping requirements: after each cleaning, the responsible person must sign and date the Cleaning Record Form. The disinfection procedure should be implemented when necessary, such as after a spillage or contamination incident, and documented in the same detail.

📘 Regulatory basis

Good Distribution Practice (GDP) expressly requires “written cleaning procedures that specify the cleaning methods, equipment and materials for different areas”. It also states that “cleaning records should be kept”.

📗 Drew Tang's recommendations

We recommend that clients display cleaning SOPs and record sheets in prominent locations in the warehouse so that staff can readily consult and follow them. Cleaning record sheets should be simple and clear, with fields for the date, time, area cleaned, person carrying out the cleaning and reviewer. It is very important to train cleaning staff regularly to ensure that they understand and strictly follow the SOP.

📕 Risk notice

The absence of written cleaning procedures and complete cleaning records is a common inspection deficiency. If the warehouse is visibly dirty, or you cannot provide cleaning records when requested by an inspector, this will be regarded as a lack of basic hygiene management. Strongly scented household cleaning agents may also be questioned, as their vapours could contaminate medicines.
