"<p><strong>HIGH RISK ASBESTOS REMOVAL<\/strong><\/p>\r\n<p>Controlled abatement of asbestos-containing materials presenting a high risk of exposure. For more information, please recite<br>The Safe Work Practices for Handling Asbestos guidelines 2017 publication.<br>Site-specific work procedures are to be developed by the abatement contractor for all high-risk work activities and submitted<br>to the Occupational Hygiene department of WorkSafe BC 48 hours prior to the start of work. Work procedures and all other<br>relevant documentation must be readily available onsite during abatement work.<br>First aid personnel, as well as a qualified site supervisor, are to be in attendance throughout the project.<br>A designated work area must be defined by fencing, warning tape, and signage that describes the risks associated with<br>entering the removal area. Barriers and signage must be present until the abatement is completed and cleared for safe entry.<br>A HEPA equipped ventilation system &#40;negative air units&#41; must be used throughout the removal process. To ensure efficacy,<br>HEPA systems must first be DOP tested on site before they are use.<br>The following are to be worn by workers participating in High-Risk work activities: Tyvek coveralls with head and foot<br>coverings, double-lined gloves, and powered air-purifying respirators (PAPRs) equipped with NIOSH 100series filters.<br>A three-staged decontamination facility is to be available, including a transfer room, shower, and clean room setup. The<br>decontamination facility is to be used before exiting the contained work area. All personal protective equipment must be<br>cleaned using a damp cloth and or a HEPA vacuum and single-use items are to be disposed of before exiting the<br>containment.<br>Polyethylene drop sheets must be used to prevent asbestos contamination in other areas. Windows, vents another opening<br>must be appropriately sealed to eliminate the migration of asbestos fibers.<br>Material saturation procedures are to be implemented using airless sprayers and pump-action water misters, frequently before<br>and during the removal of high-risk materials to reduce or eliminate dust.<br>Asbestos-containing materials should be removed while attached to substrates and intact where possible to minimize<br>disturbance and release of asbestos fibers. Asbestos debris and contaminants are to be placed in doubled up six-millimeter<br>Polyethylene asbestos waste bags \u201cgoose necked\u201d with tape and disposed of in accordance with the requirements of the<br>Occupational Health and Safety Regulation (OHSR) and disposed of in accordance with the provisions of the HWR.<br>The removal area(s) and all surfaces are to be decontaminated by HEPA vacuums and then encapsulated using applications<br>of fiber lock.<br>Daily Air Monitoring will be required throughout high-risk work to ensure risk procedures are effective, and site hygiene efforts<br>remain sufficient. Air clearance sampling is mandatory following abatement completion to rule out the presence of airborne<br>asbestos fibers. Air monitoring must be performed by a qualified third-party company possessing NIOSH 582 certification or<br>equivalent training. Appropriate techniques, work procedures, and personal protective equipment must be utilized to mitigate<br>risk to workers, occupants, and the public.<\/p>"
