Cleanrooms are critical environments used in industries such as pharmaceuticals, electronics, semiconductors, and biotechnology. In Singapore, maintaining cleanrooms to the highest standards is not just about cleanliness—it is about compliance, safety, and protecting sensitive processes from contamination.
At CCS Services, we specialize in professional cleanroom cleaning that meets international standards while adhering to Singapore’s regulatory requirements. Here’s a guide to cleanroom protocols, ISO classifications, NEA rules, and expert tips for keeping your cleanroom compliant and contamination-free.
What is a Cleanroom?
A cleanroom is a controlled environment designed to limit pollutants such as dust, airborne microbes, and chemical vapors. These facilities are classified according to ISO 14644-1 standards, which set strict limits on airborne particle counts.
Cleanroom ISO Classifications
ISO standards are used globally to define cleanroom classes. The lower the class number, the stricter the cleanliness requirements.
ISO Class 3–5: Used in semiconductor manufacturing, nanotechnology, and aerospace. Extremely stringent standards.
ISO Class 6–7: Common for pharmaceutical production and medical device assembly.
ISO Class 8–9: Suitable for less critical processes, including food production and packaging.
👉 In Singapore, many industries operate under ISO Class 5–8, depending on their sector.
NEA Rules & Local Compliance in Singapore
The National Environment Agency (NEA) sets standards for environmental cleaning and licensing. For companies operating cleanrooms:
Contractors must be NEA-licensed under the Environmental Cleaning (EC) framework.
Cleaning staff must be trained in Workforce Skills Qualifications (WSQ) modules for cleanroom cleaning.
Companies are expected to comply with the Progressive Wage Model (PWM) for fair wages and skills upgrading.
Regular audits and inspections ensure compliance with Good Manufacturing Practices (GMP) in pharmaceutical and biomedical industries.
💡 Tip: Always work with an NEA-licensed contractor like CCS Services to ensure compliance and accountability.
Best Practices for Cleanroom Cleaning
Maintaining a cleanroom requires more than standard janitorial services. Here are expert-recommended practices:
Use Cleanroom-Approved Equipment: HEPA-filtered vacuum cleaners, microfiber mops, and lint-free wipes designed for particle control.
Follow Controlled Entry Protocols: Staff must use gowning rooms, wear sterile suits, gloves, and masks before entering.
Regular Particle & Microbial Monitoring: Continuous monitoring ensures that air quality and surface cleanliness stay within ISO requirements.
Scheduled Deep Cleaning: Daily wipe-downs plus scheduled deep cleaning of walls, ceilings, floors, and equipment.
Trained & Certified Cleaning Teams: Only trained cleanroom specialists should carry out cleaning tasks, as improper methods may introduce contamination.
