Is NESHAP notification required for the mechanical removal of more than 160 square feet of asbestos-containing mastic? - ANSWER-Yes. Removal of otherwise nonfriable ACM by mechanical means will render it friable. Therefore, it is RACM and the AQMD must be notified prior to removal.
What is the federal OSHA regulation that regulates asbestos exposure for construction? - ANSWER-29 CFR 1926.1101
What types of work are included in OSHA's 29 CFR 1926.1101
- ANSWER-demolition, salvage, removal, encapsulation of
ACM, construction, alteration of ACM or construction, alteration, repair, maintenance, renovation, or clean up of debris.
What does PEL stand for? What is the PEL for asbestos? What is an EL? What is the EL for asbestos? - ANSWER-Permissible Exposure Limit. 1 / 4

0.1 f/cc for an 8 hour time weighted average (TWA).Excursion Limit 1.0 f/cc over 30 minutes at peak exposure time.
What does f/cc mean? - ANSWER-Fibers per cubic centimeter
What does PACM stand for? What materials are PACM ? - ANSWER-Presumed Asbestos Containing Materials.PACM means thermal system insulation and surfacing material found in buildings constructed no later than 1980.
What are the four classes of work defined by Cal OSHA 29 CFR 1926.1101 - ANSWER-Class 1 , Class 2 , Class 3, and Class 4
Define Class 1 from 29 CFR 1926.1101 - ANSWER-means activities involving the removal of TSI and surfacing ACM and PACM. (in amounts greater than 1 glove bag)
Define Class 2 from 29 CFR 1926.1101 - ANSWER-means activities involving the removal of ACM which is not TSI or surfacing material. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and 2 / 4
