Containment and Safety with Mold Abatement

Containment and safety issues are a critical consideration when working on any mold remediation or abatement projects. Improperly contained, the dust and bio-contaminants released can, be very harmful for both on-site workers and occupants in neighboring areas.

Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report.  If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together.  In most cases, however, there are four common considerations that will be relevant:

Monitoring Containment Area Pressure

When using negative pressure containment, it is important to monitor the pressure inside the containment in reference to the outside area.  However, because the typical negative pressure required at most abatement sites is usually only 0.020”WC, it can be difficult to find equipment sensitive enough to measure and monitor your containment area.

Omnitec Design has two options to meet this need.  Both the Watchman Differential Pressure Monitor and the self-contained Omniguard 4 Pressure Recorder are designed to provide highly accurate monitoring and alarm functions while still being easy to setup with a simple push-button calibration.

Sterilization of Filtered or Released Air

What do contractors need to know about MOLD and Mold Contamination?

Some Basics about MOLD and Mold Contamination

There are thousands of species of mold and they are constantly around us, even in the air we breathe. While most of us live our daily lives with no problem, there are others that either have or develop an allergic reaction to a toxic substance produced by mold called mycotoxins. Even this occurrence is not well understood. Mold can grow on any organic building material if there is enough moisture. It grows on wood, drywall, paint, carpet and even plastic. Mold can start to grow in just 24 to 48 hours after the moisture is added to the organic material. Mold can destroy whatever it grows on and spreads rapidly as the spores are carried from place to place by air currents and ventilation systems. Some States, i.e. California (Toxic Mold Protection Act of 2001), have attempted to define exposure limits to some of the common molds. However, through lack of funding and the complexity of the issue no one has been able to present a standardized solution. There is a consensus though on these three facts:

  • The source of the moisture infiltration must be corrected.
  • The area must be cleaned. In some areas by a licensed abatement professional.
  • Mold and mold spores must be removed from the area. Again, by a licensed abatement professional.

How to become a Certified Mold Remeditator

Reputable mold remediators should posses one of two certifications:

Certified Microbial Supervisor (CMRS) from American Institute Air Quality Association (AMIAQ)
or
Certified Microbial Remediator (CMR) from Indoor Air Quality Association ( IAQA)

They also should follow OSHA and other specified safety protocols to protect the health and safety of the mold premediators and building occupants. It is also recommended to carry multimillion dollar liability insurance to protect the client if the liability gets out of hand. Training of your employees to recognize mold, where to look for it and how to remove it are absolutely essential. Improper removal can cause spread of the mold spores through a structure very rapidly. Creating negative pressure containment around the work area with an OmniAire HEPA negative air machine is the most effective way to keep microscopic contaminants from spreading and contaminating clean and occupied parts of the structure.

 Equipment Size

As mold abatement projects vary in size, accessibility and types of contaminants, the size of the equipment has to be considered. OmniAire HEPA negative air machines come in many sizes and configurations. To accommodate the variations of the required air flow, our variable speed controller is standard on most of our equipment.

 Need Custom Equipment?

Have a large abatement or remediation job? If our specification sheets do not match your requirements, please contact us. We have a number of custom accessories such as higher efficiency filters, audible alarms, hour meters and other safety items. Most of our machines are also available with 230V 50/60Hz motors.

Air Filtration Machine vs. Neg Air vs. Air Scrubber

In general, these names are just a marketing terminology. When Air Filtration Machine is used to create negative pressure in containment, it is often called Neg Air machine. When used for recirculation and purification of air in open area, it could be called Air Scrubber or Air Filtration Machine. OmniAire machines are built to provide a high quality service in any environment and application. Your specific requirements regarding airflow, type of project, accessibility are the important factors in choosing right equipment for you. See our Comparison of OmniAire HEPA Air filtration machines.

Why UL/CSA testing?

For the safety of the users and the acceptance of the equipment on governmental, hospital and many other projects, equipment has to meet the requirements of the applicable electrical codes. To verify the UL & CSA/IEC safety compliance and listing, each machine has an identification label with name of NRTL which performed the test and the manufacturer file number.

Why is Negative Pressure Containment Used?

Use of negative pressure containment with HEPA air filtration prevents spread of asbestos fibers, mold and other contaminates to the outside of contained work area, All exhausted air is purified by HEPA negative air machine to create negative pressure and required air changes (ACH) inside the contained work area. In order to create a negative pressure environment more air must be exhausted from the space then leaking in. . See our Air Flow Calculator to assist you with your airflow requirements.

How much airflow I need?

Our Air Flow Calculator will provide a quick answer on required cfm and type of machines. Just enter the size of your work area and the number of air changes per hour (ACH). Six or more ACH are recommended for construction and renovation projects.

How often we need to be changing primary/secondary and HEPA filters?

The frequency of changing filters depends on:

  • Amount and size of airborne dust particulates
  • Airflow requirements
  • High static pressure drop across the filters (see User Manual)
  • Risk of cross contamination from one project to another

Dustlock primary/secondary filter should be replaced when its orange, downstream side shows signs of discoloring by dust. Our dual density poly media captures particulates in full depth of the filter media rather than on the surface, as pleated filters do. The m edia is treated with tactifier to prevent release of captured dust and antimicrobial additive to prevent growth of virus and bacteria. Frequent replacement will help to maintain high airflow and protect the more expensive HEPA filter.

HEPA filters should be replaced when the airflow decreases below your requirements or when pressure (“WC) across the filter increases to recommended replacement pressure – See User Manual. Some of our OmniAire air filtration machines are equipped with a simple Filter Change light to indicate that filters should be checked or replaced.

HEPA filters become even more efficient when loaded with particulate matter, but the airflow resistance increases and the airflow could be reduced to zero. Average HEPA filter life is 800 t0 1000 operation hours.

What is HEPA filter?

High-efficiency particulate air or HEPA is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, abatement of asbestos, mold and lead, restoration after water damage and many other. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). To qualify as HEPA by US government standards, an air filter must remove 99.97% of all particles greater than 0.3 micrometer from the air that passes thru the filter. Click HEPA filters for more…

How do I control odors and VOCs without chemicals?

The odor and VOCs can be removed from air with OdorGuard600 and Vapor Trap carbon web filter added to OmniAire machine. For odors associated with water damage, sewer flood, fires and mold, use our PEROx air purifier to destroy safely the source of odor without using chemicals. PEROx unit contains Ionized-Hydro–peroxide generator which is very effective in destroying all types of VOCs, chemical fumes, decay odors, mold spores, virus and bacteria. This purification process is safe for workers and inhabitants.
