Can you Save Money and Energy Reducing HVAC in Cleanrooms?

by Gerbig in General Cleanroom, Procedure. Comments Off on Can you Save Money and Energy Reducing HVAC in Cleanrooms?

One of the greatest expenses and energy drains in a cleanroom is the HVAC system. Air change rates, pressurization, temperature, and humidity are all monitored to maintain compliance for cleanroom classification. This accounts for about 80% of the energy used, and about 50% of that comes from that fans alone.

With strict guidelines on air quality and regulation, the HVAC systems are typically left to run at full power all the time. If you can reduce the amount of energy used by the HVAC or even shut the system down while the room is not in use (e.g. evenings and weekends), it would result in a significant cost and energy savings. The question is: is it possible to reduce the air change rates without compromising the microbial growth in a sterile environment?

According to research, yes, it might be possible to… Read more

A Commonly and Dangerously Ignored Cleanroom Rule

If you work in a cleanroom, you know it is imperative to follow protocol. To keep contaminates out and protect yourself from toxic substances, you likely use a variety of protective wear like gowns and gloves when you work. Even though gloves provide an excellent barrier between you and what you touch, it is important to take an extra step in safety. Are you washing your hands before and after wearing gloves?

If you’re not, you need to start immediately, and here is why.

Latex gloves are not 100% impenetrable. There is a chance that contaminates from your hands can break the glove barrier. You need clean hands before you even put the gloves on to protect the controlled environment.

Glove residue can break down your tolerance to irritants. Gloves often contain materials that can cause allergies. The allergens rub off on… Read more

Proper Monitoring of the Cleanroom Environment: Reminders

by Gerbig in Procedure. Comments Off on Proper Monitoring of the Cleanroom Environment: Reminders

Softwall-Gownroom.jpgCleanrooms have to meet all relevant regulatory requirements that are mandated for the products being manufactured. These are agencies like the Institute of Environmental Sciences and Technology (IEST) and the International Organization for Standardization (ISO).

In order to ensure continued compliance, manufacturers need to understand what environmental factors cause contaminates, and they need proper equipment to test for them. Here are a few reminders for your cleanroom plan.

First and foremost, remember that personnel produce the most contaminates in a controlled environment. In addition to covering people with proper garments, keep in mind:

  • Personnel should practice good personal hygiene
  • If anyone has a skin or respiratory condition, he or she should not work in the cleanroom until it clears up
  • The risk of human flora contamination increases when people perspire, so ensure that the temperature… Read more
