Cleanroom garment for any unexpected situation

UNICA engineering professionals have prepared the text for the publication based on Hilary Ashford’s article published in January 2016 (www.cleanroomtechnology.com)

This article is about last trends and achievements in personnel protections technologies in 2015.

Without any doubt, the main source of contamination for the production area is working stuff of this area; hence, the main thing in contamination protection is cleanroom garment.

German company DASTEX conducted a research on measuring microbiological contamination and cleanroom garment efficiency via “Biotrack” particle counter installed in “Body Box” chamber. The research revealed that though it is impossible to reach complete protection, still the reduction can be up to 1% for 1 µm microbes and bigger and 0,3% for 5 µm microbes and bigger.

Nevertheless, the quality of garment itself may not provide expected results if dressed or fitted in a wrong way.

Improved structure of production garment

DuPont with the help of Jhpiego developed the improved garment to work in conditions of Ebola epidemic. The zipper is located on the backside providing less risky undressing. The model can also be equipped with built-in impermeable hood, providing good overview. The first examples are expected to appear on the market in 2016.

Antimicrobial properties

In 2015, two companies produced antimicrobial garment. Life Threads company technology uses Zinci Pyrithionum in production of textile products for medical purposes. Zinci Pyrithionum possesses antimicrobial and antifungal properties and it is used in shampoo production.

Dow Chemical developed Silvadur technology perfect for removing bacterial and microbial contamination, apart from that, it can withstand high-temperature treatment and washing with the use of chlorine-containing reagents, thereby increasing the life of textile products.

One more company, Vestagen Technical Textiles, received prestigious Edison Award for the implementation of active barrier protection technology, which is using anti-microbial liquid ingredient that combines water- and airtight properties.

Medical lab coats, mops for cleaning floors and patients clothing made by Vestex technology, proved highly effective protection of employees in health facilities from contaminants that can spread to patients and people around them. These textiles are produced and disposed directly on the production lines of the company Vestagen Technical Textiles and distributed by approved distributors.

Innovative cleaning methods

Fraunhofer IPA, Europe's largest organization specializing in applied research, in the past year, has received the reward for an innovative system of cleaning particles that uses a built-in photodynamic disinfection process clothing for cleanrooms. This technology disinfects clothing for cleanrooms by light.

There is also a new trend of choosing solutions in which operator does not interact with contamination at all. This is because half of all medical devices are rated as potentially dangerous with OEL of <10 µkg/m3.

Personal Protection Equipment only protects the operator, hence the contaminants should not be accumulated anywhere, that means replacing filters, cleaning cleanroom and equipment located inside and outside it.

Production without use of personnel protection equipment is already widely spread (for example, isolator technology), and no longer need to prove its effectiveness. This technology can be applied for production of any medical device. The main question is whether pharmaceutical industry is ready for such great changes. Nowadays traditional technologies have less capital cost.

Although personal protection equipment manufacturers work hard to improve the level of comfort, suitability and effectiveness of its products, in the end, only a worldwide regulatory requirement on improvement of the operator protection, which will determine the development of the market.
