Are other engineering controls and work practices used to control asbestos emissions during removal?
In addition to the emission controls (e.g., wet methods, prompt clean up and disposal of RACM wastes) described above, asbestos removal work must be performed using control methods, such as vacuum cleaners equipped with high efficiency particulate air (HEPA) filters to collect all debris and dust containing ACM.
In addition, to achieve compliance with OSHA permissible exposure limits, your facility must use control methods including, but not limited to:
Local exhaust ventilation equipped with HEPA filter dust collection systems.
Enclosure or isolation of those processes producing asbestos dust.
Ventilation of the regulated area to move contaminated air away from the breathing zone of workers and toward a filtration or collection device equipped with a HEPA filter.
To ensure that airborne asbestos does not migrate from the regulated area, your facility can also use critical barriers or another barrier or isolation method. A critical barrier is one or more layers of plastic sealed over all openings into a work area or any other physical barrier sufficient to prevent airborne asbestos in the work area from migrating to an adjacent area.
