SUPERVISOR NJ ANSWERS AND QUESTIONS SET A+
✔✔AHERA (Asbestos Hazardous Emergency Response Act) <final air sampling> for
removal, enclosure, or encapsulation requires that: - ✔✔If < 260 linear ft or < 160ft^2 it's
OK to use PCM (Phase contrast Micros.) If > 260 linear ft or >160 ft^2 only use TEM
(Transmission Electron Mic.)
✔✔Federal employees - ✔✔Employees of local education agencies who perform
operations and maintenance (O&M), and repair activities involving ACM are protected
not by OSHA, but instead - are protected by US-EPA 40CFE763: Worker protection -

✔✔If the fiber exposure levels inside the work area increased from 0.2 f/cc to 2 f/cc
what could have caused this increase? - ✔✔ACM was not sufficiently wet.
✔✔What is considered "sufficiently wet" - ✔✔• sufficiently wet or adequately wet means
that sufficient mix or penetrate solution (surfactant) has been added to liquid (water) and
applied to the ACM surface so as to prevent the release of particulates.
• If visible emissions are observed coming from ACM. Then that material has not been
adequately wetted.
