NJ Asbestos Abatement cheat sheet

Negative air pressure: maintain at least -0.02 inches of water column relative to adjacent areas; use HEPA-filtered negative air machines sized to achieve 4 air changes per hour in the containment.

Containment construction: seal all openings with 6-mil fire-retardant polyethylene; use critical barriers to isolate HVAC and other penetrations; entry via three-stage decontamination unit (clean, shower, dirty).

Wet methods: saturate ACM with amended water (water plus surfactant) before and during disturbance to suppress fiber release; avoid excessive wetting that creates runoff.

Gross removal: remove ACM in largest possible sections; for pipe insulation, cut in sections and lower, not drop; for surfacing material, use scraping with wet methods and HEPA vacuuming.

Final cleaning: HEPA vacuum all surfaces, wet wipe with amended water, then perform visual inspection; clearance air monitoring required after final cleaning.

Waste handling: bag or wrap ACM in 6-mil labeled polyethylene; use leak-proof, dust-free containers; label with OSHA warning and EPA generator info.

Decontamination: workers exit through dirty room (remove suit), shower, clean room (dress); equipment and waste exit via load-out with double bagging.

Clearance criteria: PCM analysis of air samples must show <0.01 f/cc (or background level) in all samples; TEM may be required for certain projects.

Regulated asbestos-containing material (RACM): any material containing >1% asbestos by weight, including Category I (non-friable) and Category II (friable) materials.

Friability: ability of a material to be crumbled, pulverized, or reduced to powder by hand pressure when dry; friable ACM poses greater fiber release risk.

Asbestos types: serpentine group (chrysotile) and amphibole group (amosite, crocidolite, anthophyllite, tremolite, actinolite); chrysotile accounts for ~95% of commercial use.

Health effects: asbestosis (fibrosis), lung cancer, mesothelioma (pleural/peritoneal), and other cancers (larynx, ovary, GI); risk increases with cumulative exposure and smoking synergy.

Latency: asbestos-related diseases typically have 10-40 year latency; symptoms may appear decades after exposure.

Fiber size: fibers >5 µm length, <3 µm diameter, aspect ratio >3:1 are counted by PCM; WHO fibers are those dimensions.

Common ACM: thermal system insulation (pipe/boiler), surfacing materials (sprayed-on fireproofing, acoustic ceiling), and miscellaneous (floor tile, mastic, roofing, gaskets).

Bulk sampling: collect in a dust-free manner, use wet methods and HEPA vacuum; avoid cross-contamination; send to accredited lab for PLM or TEM analysis.

Respiratory protection: minimum half-mask APR with HEPA filters for Class II work; full-facepiece PAPR for Class I; supplied-air respirator for Class III; follow OSHA 29 CFR 1910.134 fit testing and medical evaluation.

Protective clothing: disposable Tyvek coveralls with hood and foot covers; double-suit for gross removal; no exposed skin; change before leaving containment.

Decontamination: mandatory shower at end of shift; wash hands and face; do not eat, drink, or smoke in work area; store street clothes separately.

Exposure limits: OSHA PEL 0.1 f/cc TWA (8-hr); STEL 1.0 f/cc (30 min); excursion limit 1.0 f/cc; NIOSH REL 0.1 f/cc; ACGIH TLV 0.1 f/cc.

Air monitoring: personal breathing zone samples required for workers; area samples for engineering control; use NIOSH 7400 PCM method; results posted within 5 working days.

Medical surveillance: required for employees exposed above PEL or STEL for 30+ days/year; includes physical exam, chest X-ray, pulmonary function test, and exposure history.

Training: initial 4-hour awareness training for Class III/IV; 32-hour worker training for Class I/II; annual refresher; hands-on training required.

Hygiene facilities: provide clean changing area, shower, and dirty changing area; ensure workers shower before leaving site; prohibit take-home contamination.

NESHAP (40 CFR Part 61, Subpart M): regulates asbestos during demolition/renovation; requires notification to EPA or delegated state at least 10 working days before start for projects above threshold (260 linear ft, 160 sq ft, or 35 cu ft).

OSHA standards: 29 CFR 1926.1101 for construction (abatement); 29 CFR 1910.1001 for general industry; covers exposure limits, monitoring, PPE, training, and competent person.

EPA Worker Protection Rule (40 CFR Part 763, Subpart G): extends OSHA worker protection to state/local government employees not covered by OSHA.

AHERA (40 CFR Part 763, Subpart E): requires accreditation for inspectors, management planners, project designers, supervisors, and workers; model accreditation plan (MAP) training courses.

State certification: many states (e.g., NJ) require licensing for asbestos abatement contractors, supervisors, and workers; separate certification for inspectors and project designers; reciprocity varies.

Permit requirements: obtain local/state permits before abatement; submit project notification, abatement plan, and fees; post permits on site.

Waste disposal: asbestos waste is regulated under RCRA as a special waste in some states; manifest required; dispose at approved landfill; keep records for at least 2 years (NESHAP) or longer per state.

Recordkeeping: retain training certificates, medical records, exposure monitoring, and waste manifests; OSHA requires exposure records for 30 years and medical records for duration of employment plus 30 years.
