  19. Demolition
    Wrecking/taking out any load-barring structural member
  20. Encapsulation
    Use of an agent to seal the surface or penetrate the bulk of ACM.
  21. Enclosure
    A resilient structure built or sprayed around ACM designed to prevent disturbance & contain released fibers.
  22. Excursion Limit (EL)
    • A level of airborne fibers specified by OSHA as a short term excursion level.
    • Current EL = 1.0 f/cc of air, over a 30-min time-weighted ave (measured w phase contrast microscopy)

    Fibers per cubic centimeters of air
  24. General Liability Insurance
    Covers the insured for damage to property & person caused by insured's negligence.
