Mistakes to Avoid When Designing Cleanroom Electrical and Lighting Systems

1. Introduction

Electrical and lighting systems play an important role in cleanroom design, ensuring a safe, stable and GMP, ISO 14644-1 standard working environment. However, if not designed properly, this system can cause many problems affecting operating efficiency and cleanroom cleanliness.

In this article, Anh Khang Cleanroom will help you identify common mistakes to avoid when designing electrical and lighting systems for cleanrooms.

2. Mistakes When Designing Cleanroom Electrical Systems

2.1. Incorrect Electrical Capacity Calculation

Some businesses design electrical systems without budgeting enough capacity, leading to overloading or unstable operation. This can cause sudden power outages, disrupting the production process and affecting product quality.

Solution:

• Calculate electrical capacity based on the total load of all equipment in the cleanroom, including: HVAC systems, production machinery, lighting and measuring equipment.
• Reserve 10-20% capacity to ensure stable operation.

2.2. Irrational Electrical Wiring Routing

Misplaced electrical wires can affect airflow in the cleanroom, causing contamination or hindering maintenance operations.

Solution:

• Electrical wires should be installed in concealed wall technical boxes or run on the ceiling to avoid affecting the cleanroom environment.
• Clearly label the electrical system for easy inspection and repair when needed.                                                                                     Standardized lighting system in cleanroom

2.3. Using Substandard Materials

Substandard electrical wires, electrical cabinets or switching devices can generate static electricity or generate dust, affecting production quality.

Solution:

• Use anti-static materials that meet cleanroom standards such as NFPA 70, IEC 60364.
• Choose sealed, dust-proof and moisture-proof electrical cabinets that meet IP54 or higher.

2.4. Lack of Electromagnetic Interference (EMI) Protection Solutions

In cleanrooms, measuring and production equipment is highly sensitive to electromagnetic interference. Without anti-interference measures, signals can be distorted, affecting the production process.

Solution:

• Install EMI electromagnetic interference filters for the electrical system.
• Use shielded cables to reduce the impact of electrical sources.

3. Mistakes When Designing Cleanroom Lighting Systems

3.1. Choosing Non-Standard Cleanroom Lights

Some businesses use regular lights that do not have dust resistance, leading to the generation of dust particles in the cleanroom.

Solution:

• Use cleanroom LED lights that meet IP65 and above standards, which are dustproof and waterproof.
• Lights must have an anti-static shell to avoid affecting the production environment.                                                                                     Dedicated LED lights for cleanrooms

3.2. Lack of Uniformity in Lighting Intensity

If the lighting system is not designed evenly, some areas may be under-lit or over-lit, affecting work productivity and product quality inspection capabilities.

Solution:

• Calculate lighting levels according to standards: 300-500 lux for production areas, 500-1000 lux for quality control areas.
• Use lighting simulation software to optimize light installation locations.

3.3. Failure to Install Emergency Lighting Systems

In the event of a power outage or incident, the cleanroom needs to have a backup lighting system to ensure safety and maintain operations.

Solution:

• Install emergency lights at aisles, exits, and critical areas.
• Use a UPS (uninterruptible power supply) system to maintain lighting in case of an incident.

3.4. Failure to Periodically Check Lighting Systems

Many businesses install lighting systems but do not periodically check them, leading to damaged lights that are not detected in time.

Solution:

• Conduct lighting system checks every 6 months.
• Replace bulbs when brightness drops below 70% of the initial level.
