"<p><strong>HIGH-RISK ASBESTOS REMOVAL<\/strong><\/p>\r\n<p><strong><\/strong><\/p>\r\n<p>WorkSafe BC - High-Risk asbestos removal procedures must be followed for the safe and controlled abatement of\u00a0asbestos-containing materials presenting a high risk of exposure. For more information, please recite The Safe Work\u00a0Practices for Handling Asbestos guidelines 2017 publication.<\/p>\r\n<p>Site-specific work procedures are to be developed by the abatement contractor for all high-risk work activities and submitted to the Occupational Hygiene department of WorkSafeBC 48 hours prior to the start of work. Work procedures and all other relevant documentation must be readily available onsite during abatement work. First aid personnel, as well as a qualified site supervisor, are to be in attendance throughout the project;<\/p>\r\n<p>A designated work area must be defined by fencing, warning tape, and signage that describes the risks associated with entering the removal area. Barriers and signage must be present until the abatement is completed and cleared\u00a0for safe entry;<\/p>\r\n<p>A HEPA equipped ventilation system &#40;negative air units&#41; must be used throughout the removal process. To ensure efficacy, HEPA systems must first be DOP tested on site before they are put to use;<\/p>\r\n<p>The following are to be worn by workers participating in High-Risk work activities: Tyvek coveralls with head and\u00a0foot coverings, double-lined gloves, and powered air-purifying respirators (PAPRs) equipped with NIOSH 100 series\u00a0filters;<\/p>\r\n<p>A three-staged decontamination facility is to be available, including a transfer room, shower, and clean room setup.\u00a0The decontamination facility is to be used before exiting the contained work area. All personal protective\u00a0equipment must be cleaned using a damp cloth and or a HEPA vacuum and single-use items are to be disposed of\u00a0before exiting the containment;<\/p>\r\n<p>Polyethylene drop sheets must be used to prevent asbestos contamination in other areas. Windows, vents and\u00a0other openings must be appropriately sealed to eliminate the migration of asbestos fibres;<\/p>\r\n<p>Material saturation procedures are to be implemented using airless sprayers and pump-action water misters,\u00a0frequently before and during the removal of high-risk materials to reduce or eliminate dust;<\/p>\r\n<p>Asbestos-containing materials should be removed while attached to substrates and intact where possible to\u00a0minimize disturbance and release of asbestos fibres;<\/p>\r\n<p>Asbestos debris and contaminants are to be placed in doubled up six-millimetre Polyethylene asbestos waste bags \u201cgoose necked\u201d with tape and disposed of in accordance with the requirements of the Occupational Health and Safety Regulation (OHSR) and disposed of in accordance with the provisions of the HWR;<\/p>\r\n<p>The removal area(s) and all surfaces are to be decontaminated by HEPA vacuums and then encapsulated using\u00a0applications of fibre lock;<\/p>\r\n<p>Daily Air Monitoring will be required throughout high-risk work to ensure risk procedures are effective, and site\u00a0hygiene efforts remain sufficient. Air clearance sampling is mandatory following abatement completion to rule out\u00a0the presence of airborne asbestos fibres. Air monitoring must be performed by a qualified third party company\u00a0possessing NIOSH 582 certification or equivalent training;<\/p>\r\n<p>Appropriate techniques, work procedures, and personal protective equipment must be utilized to mitigate risk to\u00a0workers, occupants and the general public.<\/p>"
