The Mack Group Completes Asbestos Removal Project

The Mack Group, LLC, an asbestos abatement and removal contractor, recently completed a large project consisting of the abatement of various large quantities of asbestos containing materials. The project was completed for a large, global chemical company.

All work was performed following all OSHA & EPA regulations as they pertain to asbestos abatement.

Mobilization to the site required that several tasks be completed with attention to detail. This included the placement of all required signage on all entrances to the work area, installing connections to electric and water and the building of separation barriers and a decontamination facility.

The preparation for asbestos work/pre-asbestos demolition was conducted using modified containments and the establishment of a negative air environment for dust control. Tasks during this phase included installing all temporary electric w/ ground fault interrupter circuitry (GFI), installation of 2 layers of fire rated 6-mil poly on all critical barriers, installation of negative air units enough to create 4 changes per hour, removal all ceiling tile and grid from work area to allow access for cutting and capping of MEP, removal of all sheetrock not impacting any asbestos, removal of all carpeting not impacting any asbestos, removal of all bathroom fixtures, partitions, tile floors and walls, removal of all identified MEP and the installation of chutes to facilitate disposal.

There was a significant amount of ACM that needed to be properly and safely abated. Quantities included 14,200sf of transite interior walls, 9,875sf of tile and mastic, 300 lf of pipe and 198 pipe fittings. All ACM was removed using wet methods. The types of equipment utilized to efficiently remove the ACM included Micro Traps (air filtration units), HEPA Vacs, ladders, lifts, airless sprayers, respirators, air monitoring equipment, cutting tools, chutes, slides, Lull, skid steers, loaders, PPE, and an assortment of hand & power tools.

Mastic and tile were abated using chemical and Blastrac flooring removal units. Transite partitions, ducts and piping were also removed using wet methods. All ACM waste was removed from the work area through the air lock / waste chamber then directly into 6 mil poly lined dumpsters/ trailers with the proper OSHA labeling and generator labels.

Final cleanup of the work area included inspection of the work area to insure all material had been removed, a final wet wipe and HEPA vacuum of all equipment and encapsulation with a lockdown encapsulant.

The Mack Group was responsible for all OSHA sampling, recalculation of air pumps, etc. during the course of the work. Mack Group’s competent person provided oversight and managed the utilization of personal air pumps on workers and analysis by an independent third party laboratory. Results were posted onsite.

All ACM waste was disposed in an approved EPA landfill as per regulations, complete with all required documentation and manifests.

The project was completed in one month and without incident or injury.
