检验试验室5S管理 5S Management in Testing Laboratories

gaowenhua

检验实验室的 5S管理（整理、整顿、清扫、清洁、素养）是实现高效、准确、安全和专业化的基础。


它不仅仅是“打扫卫生”，而是一套系统化的现场管理方法，能显著提升实验室的工作效率、数据可靠性、人员安全和专业形象

gaowenhua

The 5S management (Sorting, Straightening, Sweeping, Standardizing, and Sustaining) in testing laboratories serves as the foundation for achieving efficiency, accuracy, safety, and professionalism.

It is not merely "cleaning," but a systematic on-site management approach that significantly enhances laboratory efficiency, data reliability, personnel safety, and professional image

3S

清扫

Seiso

清除污垢，保持环境干净。

• 每日清洁工作台、仪器表面、通风柜。
• 定期清洁冰箱、培养箱、灭菌锅内部。
• 清理水槽、废液桶，防止堵塞和异味。

4S

清洁

Seiketsu

标准化前3S，维持成果。

• 制定《5S检查表》，每日/每周检查。
• 明确清洁责任区域和频次（如“谁、何时、做什么”）。
• 将5S要求写入SOP或实验室管理规程。

5S

素养

Shitsuke

养成习惯，自觉遵守规范。

• 员工自觉物归原位、及时清洁。
• 主动报告安全隐患或改进点。
• 新员工培训包含5S内容，形成文化。

Application examples of S Chinese English core meaning laboratory
1S Organize Seiri to distinguish between essential and non essential items, and eliminate non essential items. Clean up expired reagents, standards, and culture media.
Scrap damaged glassware and pipettes.
Remove useless files, expired SOPs, and discarded equipment.
2S rectification Seiton essential items are positioned for easy access. Reagents should be stored in separate areas by category (acid, base, organic solvent) with labels facing outward.
Commonly used pipettes and consumables should be placed in easily accessible locations and clearly labeled.
The instrument operating table only holds the items required for the current experiment.
3S cleaning Seiso to remove dirt and maintain a clean environment. Clean the workbench, instrument surface, and fume hood daily.
Regularly clean the interior of refrigerators, incubators, and sterilization pots.
Clean the sink and waste liquid tank to prevent blockages and odors.
4S cleaning Seiketsu standardized for the first 3 seconds to maintain results. Develop a 5S checklist and conduct daily/weekly inspections.
• Clearly define the cleaning responsibility area and frequency (such as "who, when, what to do").
Write 5S requirements into SOP or laboratory management procedures.
5S literacy Shitsuke cultivates habits and consciously abides by norms. Employees should consciously return items to their original positions and clean them in a timely manner.
Proactively report safety hazards or improvement points.
New employee training includes 5S content to create a culture.

1. 整理（Seiri）—— “要”与“不要”的决断

• 关键：避免“以后可能用到”的心态。
• 方法：
  • 使用“红标签作战”：给所有物品贴标签，判断是否必需，非必需的贴红标并限期处理。
  • 设立“待处理区”：集中存放待报废、待转移的物品，避免散落。
    
• 实验室重点：
  • 试剂：检查有效期，过期立即处理。
  • 样品：明确保存期限，过期样品按规定销毁。
  • 文件：保留现行有效SOP，作废文件归档或销毁

1. Seiri - Deciding between "want" and "don't"
Key: Avoid the mentality of 'may be used in the future'.
Method:
Use 'Red Label Battle': Label all items, determine if they are necessary, label non essential items with red labels and set a deadline for processing.
Establish a 'waiting area': centralize the storage of items to be scrapped or transferred to avoid scattering.
Laboratory focus:
Reagent: Check the expiration date and handle it immediately upon expiration.
Sample: Clearly define the shelf life, and dispose of expired samples according to regulations.
Document: Retain the current valid SOP, archive or destroy obsolete documents

整顿（Seiton）—— “三定”原则：定点、定容、定量
定点：每样物品都有固定位置。
绘制“物品定位图”，如试剂柜布局图、仪器台面定置图。
定容：规定存放容器。
统一使用透明收纳盒，便于查看。
危险化学品使用专用防爆柜。
定量：规定最大/最小库存量。
避免试剂过多占用空间或过期；避免耗材短缺影响实验。
可视化管理：
使用标签、色标、影子板（Shadows Board）标识位置。
例如：移液器架上画出轮廓，用完必须放回原位。

Seiton Rectification - "Three Determinations" Principle: Fixed Point, Fixed Volume, and Fixed Quantity
Fixed point: Each item has a fixed position.
Draw an "item positioning diagram", such as a layout diagram of a reagent cabinet or a layout diagram of an instrument table.
Fixed volume: Specify the storage container.
Unified use of transparent storage boxes for easy viewing.
Special explosion-proof cabinet for the use of hazardous chemicals.
Quantitative: Specify the maximum/minimum inventory level.
Avoid excessive use of space or expiration of reagents; Prevent the shortage of consumables from affecting the experiment.
Visual management:
Use labels, color codes, and Shadows Boards to identify locations.
For example, draw a contour on the pipette holder and put it back in its original position after use.

清扫（Seiso）—— 点检与发现

• 清扫即点检：在清洁过程中，检查设备是否异常（如漏液、异响）、物品是否损坏。
• 责任到人：划分“5S责任区”，明确每个区域的负责人。
• 高频区域重点清洁：
  • 生物安全柜/超净台：使用前后必须清洁消毒。
  • 天平：每次使用后清洁，防止交叉污染。
  • 离心机：定期清理转子和腔体，防止腐蚀和不平衡

Cleaning (Seiso) - Inspection and Discovery
Cleaning and inspection: During the cleaning process, check whether the equipment is abnormal (such as leaking liquid, abnormal noise), and whether the items are damaged.
Responsibility to individuals: Divide the "5S responsibility area" and clarify the responsible person for each area.
Key cleaning in high-frequency areas:
Biosafety cabinet/ultra clean table: It must be cleaned and disinfected before and after use.
Balance: Clean after each use to prevent cross contamination.
Centrifuge: Regularly clean the rotor and chamber to prevent corrosion and imbalance
