Cleanroom laundry

Compiled by Angela Godwin

Garments play an important role in maintaining the cleanliness of a cleanroom or critical environment. Whether your facility chooses to rent garments or send its own out for laundering, an efficient, certified garment-laundering program is essential for ensuring the integrity of cleanroom wearables.

Cleanroom dryer with ionizer and particle counter

The Ultra Clean dryer is equipped with an ionizer to help eliminate static electricity, allowing particles to be released and lowering the particle count of cleanroom garments. When cleanroom gowns build up static electricity and have a positive charge, negative ions from the ionizer will be attracted. When the particles are neutralized, they are free to be carried away in the air stream. This feature is recommended on ISO Class 3 and 4 (Class 1 and 10) cleanroom dryers. The Ultra Clean dryer can also be equipped with a particle counter. It includes a pick-up probe strategically located in the discharge air, a purge system designed to minimize any possible contamination of the tubing, a particle counter, and a heat exchanger to eliminate fogging of the particle-counter lens. Stainless-steel tubing from the pick-up probe runs vertically to keep moisture away from the particle counter and serve as a heat exchanger, ensuring that the air sample entering the particle counter will not have excess moisture or exceed the operating temperature of the particle counter. The SS tubing is cooled and purged during the drying cycle so it will be clean and will cool the air being sampled by the particle counter during the cool-down cycle. This eliminates possibly slugging (overloading) the particle counter, contaminating the tubing and overheating the particle counter. At the end of the cool-down cycle, the particle count can be read. If the count is high, additional cool-down can be run. If the particle count is acceptable, the dryer can be unloaded and gowns (product) delivered to the packaging area.

Antimicrobial surface coating

HaloShield® is a revolutionary new surface coating that Medline Industries, Inc. is applying to sheets and underpads to help healthcare facilities combat two major challenges: infection and odor control. This powerful coating, when applied to nearly any type of textile, harnesses the antimicrobial properties of chlorine-based sanitizers added to a regular wash cycle to continuously kill bacteria long after the last laundering. HaloShield is a rechargeable technology-the antimicrobial properties of chlorine renew each time the fabric is laundered in an EPA-registered chlorine-based sanitizer. Healthcare laundry protocols have long relied on chlorine-based sanitizers, which evaporate soon after laundering. However, textiles enhanced with HaloShield technology maintain the ability to bind chlorine to the product for the duration of its life, with no detectable odor or change of texture. HaloShield prevents the chlorine from dissipating and allows it to continuously attack and kill bacteria. Lab tests show that when bacteria comes into contact with chlorine bleach anchored to a HaloShield treated sheet, 99.9 percent of the microbes are killed within minutes, including MRSA, VRE, and K. pneumoniae (pathogens notorious for nosocomial infections).

Independent tests were conducted with the International Fabricare Institute and NAMSA laboratories: At the final test point (70 launderings), the samples gave a 2.53 log kill (this is equivalent to 99.71 percent), demonstrating that the antimicrobial properties of HaloShield were still present and effectively killing bacteria after a significant amount of usage. Medline will introduce HaloShield lab coats this fall. Medline licenses HaloShield from Vanson HaloSource, with exclusive rights to distribute HaloShield-treated hospital sheets, pillowcases, scrubs, gowns, cubicle curtains and reusable underpads in North and South America. Vanson HaloSource is a bioscience company that pioneers antimicrobial and other advanced technologies being applied to improve health and safety in environments where sanitation is critical.
