Who cleans your cleanroom? If you’re in the majority, your cleanroom workers are also taking on detailed cleaning responsibilities. Controlled Environments recently published the latest “Cleanroom Trends and Salary Survey,” and the cleaning trends have changed since last year. While the trend to use cleanroom workers as the primary cleaning staff rose slightly, from 42% to 46.3%, the other two categories saw significant change. People using an in-house cleaning staff dropped from 33% to 20.7%. Responders who say they outsource cleaning rose from 24% to 32.9%.
What’s causing fewer people to employ an in-house cleaning staff and more people to hire an outside cleaning company?
The most obvious reason a cleanroom facility wouldn’t hire an outside cleaning company is the expense. So if outsourcing is becoming more popular, the value of this service is probably becoming more evident. Let’s look at… Read more
If you’re using or considering a standard Class III Bio Safety Cabinet, you may find it more beneficial to use a High Containment Glove box.
The pharmaceutical industry deals with a lot of different chemicals and compounds. Personnel protection is of great concern for Class III biological applications. That’s why the Class III Biological Safety Cabinets (BSCs) are designed with the highest containment capabilities – keeping people, products, and the environment safe. Typical glove boxes are Class II cabinets, and not appropriate for this industry. However, High Containment Glove boxes (HCGs) are akin to Class III BSCs, but with added benefits.
Used in the pharm industry for years, HCGs are totally enclosed, HEPA filtered boxes with glove ports. They have been known to provide better environmental attributes than standard BSCs. Here are a few of the benefits by comparison:
- Nothing in… Read more
How can pharmaceutical cleanrooms ensure compliance between certification visits if they don’t have centralized airflow monitoring?
Some existing pharmaceutical cleanrooms were designed without centralized monitoring systems. For these facility managers, certification is their primary means of ensuring compliance. It would be ideal, however, to know when intervention may be necessary during daily operations. The big question is: how do you accomplish this without adding considerable cost or disrupting the facility?
In the absence of airflow monitoring, what makes the most sense is to monitor the differential pressure maintained between the controlled environments and surrounding space. When changes occur in differential pressure, it often means that there are filter blockages or FFU failures. This is enough information to investigate the source of a problem.
The simplest way to accomplish this is with stand-alone censors. You can mount them inside the cleanroom so that… Read more
Environmental factors can create unexpected problems with your air intake system. Don’t be susceptible to these surprises. Know how to prepare.
When you complete construction on a cleanroom, the last thing you want to find is that you overlooked a major source of contamination. One of the most missed pieces in the design phase is the environment surrounding the facility. There are numerous ways the external environment can hinder your efforts to maintain proper indoor air quality. Missing one can cause a lot of agony for you later on.
In the last article on indoor environmental concerns, we focused largely on humidity. This is one of the most obvious detrimental influences in the environment, both outside and in. If the climate you’re in gets humid, you do need to factor that in when designing your cleanroom.
It doesn’t stop at humidity, however…. Read more
Don’t build a cleanroom without first understanding all of the environmental factors that can cost you time and money later.
Maintaining a compliant cleanroom is a complex process. Indoor air quality is fairly fragile because even the best air filters can’t prevent all influences from tainting the system. The design process is the perfect place to evaluate potential threats. You can avoid certain contaminates and know what to be watchful for once the facility is operational. One of the most important factors to evaluate is the environment.
Environmental factors are twofold: internal and external.
Let’s first look at internal environmental concerns.
Humidity is among the most difficult to completely control, and it can cause a heap of problems. Too little humidity, as you can imagine, can spark electrostatic buildup and discharge. Electrostatic discharge is a major issue in a cleanroom, especially in one… Read more
