- Cleanup of indoor air contamination caused by toxic mold resulting from building defects and water intrusion
- Very often performed for clients in connection with facility response services following water intrusion
- Involves the removal, encapsulation, and enclosure of lead-based paint, lead dust, and lead in soil
- Techniques include chemical stripping, vacuum blasting, open blasting, industrial vacuuming, and mechanical separation
Hazardous & Universal Waste Removal
- Transport hazardous materials (such as mercury), whether from planned remedial projects or from emergency spill cleanups
- Specializes in the application of spray-applied fireproofing to structural steel, serving both the new construction and renovation markets
- Performs most fireproofing work after asbestos-containing fireproofing material has been removed
What is Asbestos: A Few Facts
Asbestos was once considered the “miracle fiber” because of its wide range of physical properties and uses. With the discovery that release of asbestos fibers and subsequent inhalation and accumulation in the body cause serious health problems, liability claims increased dramatically. Today, a huge number of asbestos-related lawsuits are yet to be resolved.
Chemical stripping is performed by applying a solvent or caustic stripper to a painted surface with a brush or sprayer. Depending on the product and the thickness of the paint to be removed, the stripper remains on the surface from five minutes to up to 48 hours. Mechanical strippers, a HEPA (high-efficiency particulate air) vacuum system, or pressurized water may be used to remove chemical strippers and lead-based paints. This method minimizes airborne lead concentrations, thereby reducing environmental risks and the need for costly enclosures.
For vacuum blasting, a blast nozzle is attached to a brush-lined shroud, which is held against the lead-based coatings to be removed. The abrasive and the debris are contained within the tool itself. While blasting, a built-in vacuum system carries the material to a collection bin. The abrasive can then be disposed or cleaned and recycled. This method reduces lead exposure and minimizes containment needs.
Open abrasive blasting is similar to vacuum blasting, but without a shroud. Its advantage is speed. During the blasting process, negative pressure must be maintained, along with a powerful vacuum for dust collection. The very fast production rate compensates for the cost of the large, sophisticated equipment. Containment is essential.
Lead dust resulting from industrial or manufacturing processes must be HEPA-vacuumed and wiped from surfaces. Usually, wipe sampling is conducted to ensure that OSHA standards for cleanliness and lead contamination levels have been met.
Bullet fragments in outdoor gun ranges may release lead into soil and groundwater over time. NorthStar invented the Pneumatic Separation Unit (PSU) to segregate lead bullet fragments from soil, rocks, and debris. The PSU has recovered more than a million pounds of lead from soils in a single firing range. The recovered lead was then recycled for financial gain to the client.
Wheel blasting, electromagnetic radiation systems, CO2 blasting, and high-pressure water jetting offer alternative methods. NorthStar is also experienced with special applications for historic preservation projects. In addition, our chemical fixation technology involves incorporation of chemical reagents into lead-contaminated soil.
