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
Negative pressure containment is a requirement for capturing airborne lead and other fine dust particles that are inevitably a part of Lead Abatement Projects. Ensuring your contained area has the required air changes (ACH) and that it is adequately scrubbed prior to discharge is where you will find the OmniAire line of HEPA Air Filtration Machines a competitive advantage.
With standard airflows ranging from 50 to 18000 CFM, OmniAire Air Filtration Machines can provide the necessary ACH for any size project. To calculate which of our machines will best suit your needs, try our Air Flow Calculator in both SAE and Metric.
Following EPA regulations by maintaining adequate pressure containment, air changes, and HEPA efficiency is important to the quality of your overall project.

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 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 an accurate monitoring and alarming functions while still being easy to setup with a simple pushbutton 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.

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.
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.
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.
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.
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.
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.
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…
