Deciphering Cleanroom Glove Classifications

Hold on tight, because we’re about to get technical! Cleanroom gloves are rigorously classified based on their particle and extractable content. Let’s decode the jargon:

1. Particle Count: How Clean is Clean?

Ever wondered how many microscopic dust bunnies could be hiding on a glove? Cleanrooms have strict limits, and particle count testing is serious business. This process determines the number of particles of specific sizes present on the glove’s surface.

Gloves are often categorized as:

• Class 100/ISO 5: Ultra-clean, for the most critical environments.
• Class 1000/ISO 6: Clean, but with a slightly higher particle allowance.
• Class 10,000/ISO 7: Suitable for less sensitive cleanroom applications.

2. Extractables: Keeping Things Pure

Extractables refer to the substances that can leach out of the glove material, potentially contaminating whatever they touch.

These could include:

• Ions
• Residues (chemicals, lubricants, etc.)
• Other impurities

Testing ensures these extractable levels are within acceptable limits.

Cleanroom Glove Standards: The Nitty-Gritty

Cleanrooms don’t mess around when it comes to standards. Here are the major players in the glove game:

1. ASTM International

This powerhouse organization develops voluntary consensus standards for materials, products, systems, and services. Key standards related to cleanroom gloves include those for:

• Particle levels (ASTM D4806): Evaluating particle contamination
• Extractables (ASTM D6319): Measuring ion and other residue levels

2. International Organization for Standardization (ISO)

Ah, ISO, known for its globally recognized standards. Relevant standards for cleanroom environments and gloves include:

• ISO 14644: Establishes guidelines for classifying and controlling airborne particles in cleanrooms.
• ISO 9001: Sets quality management system requirements, crucial for cleanroom glove manufacturers.

Donning (and Doffing) Cleanroom Gloves Like a Pro

Wearing cleanroom gloves isn’t as simple as slipping on a pair of mittens. Proper donning and doffing (that’s fancy talk for putting on and taking off) techniques are critical for maintaining sterility.

The Art of Donning

1. Scrub-a-Dub-Dub: Thorough handwashing is non-negotiable! Use a specialized cleanroom soap and water system, and don’t forget those fingernails!
2. Dry Time: Completely dry your hands with a cleanroom-approved, lint-free wipe or air dryer.
3. Glove Up!: Carefully remove the gloves from their packaging, avoiding any contact with non-sterile surfaces.
4. Double Glove It!: In ultra-sensitive environments, double gloving is often required. The outer glove acts as a sacrificial layer.

The Doffing Dance: Preventing Cross-Contamination

Removing gloves without spreading those microscopic troublemakers requires finesse:

1. Outer Layer First: Pinch the cuff of one glove, careful not to touch your skin, and peel it downwards, turning it inside out.
2. The Great Escape: With the first glove off, slip two fingers of your ungloved hand under the cuff of the remaining glove, again avoiding skin contact. Peel it off, turning it inside out to contain any potential contamination.
3. Disposal Duty: Dispose of the gloves in a designated cleanroom waste container.

The Future of Cleanroom Gloves: Innovation on the Horizon
