EPA Requirements and Safety in Lead Abatement Projects

EPA requirements are designed to ensure that all work done on Lead Abatement Projects, whether interior or exterior surfaces, is done to the highest level of safety and risk management.  Containment of the generated airborne and wastewater dust and debris is critical to proper compliance and worker safety.  Improperly contained dust and debris is not only a EPA violations, but it can be very harmful for the environment, on-site workers and the occupants of 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 considerations that will be relevant:

  • Meeting Containment and Air Change Requirements
  • Monitoring of Containment Pressure
  • Discharge of Contaminated Water

Containment and Air Change Requirements

Monitoring Containment Area Pressure

OmniGuard 5

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 can be as low as 0.020”WC, it can be difficult to find equipment sensitive enough to measure and monitor your containment area.

Omnitec Design has a monitor to meet this need. The self-contained Omniguard 5 Pressure Recorder is designed to provide an accurate monitoring and alarming functions while still being easy to setup with a simple push-button calibration.

Contaminated Water Filtration


The water used to wet surfaces and wash protective gear during lead abatement work is contaminated and must be filtered prior to discharge into a general drain.

The OmniFlow Water Filtration System is a compact, portable system with a 3 GPM capacity and reliable, self priming pump. The unit has as standard 20 and 5 micron filters for removal of asbestos and lead dust. Other filters are available for lead when required.

 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.

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 a 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.

The 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.
