Asbestos Remediation

Like the asbestos abatement that precedes it, the confirmation of successful asbestos remediation encompasses several steps:

• Asbestos abatement and removal has been completed.
• Supervisor conducts a visual inspection is performed to make sure all asbestos material, including debris, has been removed.
• Initial cleaning is done by wet wiping all surfaces in the work area.
• A lockdown-encapsulated shellac is applied to all exposed surfaces and allowed to dry.
• The protective polyethylene plastic is removed.
• HEPA vacuuming and wiping of all areas is done and allowed to dry.
• Second visual inspection by supervisor to ensure all debris, residue pools of liquid and asbestos-coated materials have been removed.
• Supervisor verifies that adequate cleaning has been completed.
• Air is sampled and tested (results within 48 hours.) to confirm abatement/remediation has been successful:
• Negative pressure is stopped.
• All equipment is removed.
• Decontamination enclosures and critical barriers are disassembled.
• Removal of waste to authorized landfills is documented.
• All contents and furniture is brought back in and set up in original positions.
• The site is declared safe and occupants allowed back into building.
