Testing results prove new methods for mopping cleanrooms

Mount Prospect, IL—Extensive field testing by industry has led the Institute of Environmental Science and Technology's Working Group on cleanroom housekeeping, operating and monitoring procedures to add two alternate methods of mopping walls and floors to its recommended practice (RP) 18.2.

Filter targets smallest viruses

EAST HILLS, NY—Drug manufacturers looking for a way to remove the smallest known viruses from protein-derived products have a new weapon in their arsenal. The latest filter technology from Pall Corp. (East Hills, NY) is fine enough to efficiently remove 20 nanometer (0.02 micron) viruses, while at the same time allowing free flow of liquid protein particles as large as immunoglobulin G, a common antibody.

Pentagon lags in protective suit recall

WASHINGTON, DC?The past keeps needling a defunct manufacturer of protective clothing, and Capitol Hill continues to press the Pentagon, demanding answers as to why it took the military establishment five years to warn the armed forces about potentially defective suits intended to protect soldiers from chemical and biological weapons.

In response to Richard Matthews' Debunking the Myth column, "Enhanced clean devices," (Dec. 1999, p. 42) he states "Some would argue ... that there has been nothing new in cleanrooms lately." If 25 years qualifies an item as an antique, there are a couple of antique theories out there that should not be allowed into the current millennium.

Viewpoint: Mother knows best

My parents recently returned from Europe, heralding its wonders: the Italian hotel in which they stayed, and how the building had to be at least 500 years old; the German village in which my sister lives, and the rarity of the preserved architecture.


COLUMNS

Life Sciences


The meaning of cleaning

Cleaning takes on a whole new meaning in the area of life sciences where the objective in cleaning is to remove potential cross contamination, defined as anything that is not an ingredient in the product.


Cleanroom Standards


The ISO global cleanroom standards — What do they really mean?

Every manufacturer has some form of standard operating procedure (SOP) that dictates how his operation will run and the quality level it will produce. Some manufacturers, particularly those in the healthcare field, have to meet stringent regulatory criteria — another form of standards.

Solutions to the minienvironment mystery

The editors at CleanRooms received so many letters in response to Robert P. Donovan's October 1999 Electronics column on page 8 entitled, "The minienvironment mystery," that this month we will publish the letters and author responses in this space.

Sterilization: Steam sterilization and the myth of harmonization

International harmonization of standards has been ongoing for several years notably in the area of compendial tests and monographs. However, steam sterilization regulations and standards, especially as they affect cycle development and validation, lack consistency and uniformity among the various international regulatory bodies. Very little has been done to reconcile these differences.


Special Report


Taking ESD by storm

The electronics industry is taking a big hit. It is losing billions of dollars annually because electrostatic discharge (ESD) wreaks havoc on delicate circuitry, substrates and disk drive components. As little as 5 volts can damage the smallest and most delicate component and fewer than 100 volts can waste entire lots of electronic circuitry.

Product Comparator: Presaturated wipers optimize solvent use

Certain critical environments, from pharmaceutical, biotechnology and medical devices to semiconductor and aerospace equipment, require wet cleaning. The most widely used wipers in highly critical areas (ISO Class 5 [Class 100] and cleaner) are those made with fabrics knitted from filament polyester or nylon.
