NY Asbestos Abatement flashcards
NY Asbestos Abatement · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Asbestosis
- Chronic progressive lung fibrosis caused by inhaled asbestos fibers; dose-related, appears after latency of 15-40 years; smoking is not causative but can worsen impairment.
- Mesothelioma latency
- Malignant tumor of pleura or peritoneum linked to asbestos; latency commonly 20-50 years; risk is not limited to high exposures and smoking does not increase it.
- Smoking and asbestos
- Cigarette smoking and asbestos exposure multiply lung cancer risk; combined risk far exceeds additive; smoking does not increase mesothelioma or asbestosis risk.
- OSHA asbestos medical exam
- Required for employees at or above the PEL 30 or more days per year; includes medical history, physical, PA chest X-ray, and pulmonary function tests; offered at assignment and annually.
- B-reader chest X-ray
- Chest radiograph for asbestos surveillance is PA 14x17 and interpreted by a B-reader or board-certified radiologist using ILO classification.
- Medical record retention
- OSHA asbestos medical records are kept for duration of employment plus 30 years; exposure records are kept 30 years; employees must be told about records.
- NY asbestos project notification
- Written notice to NYSDOL at least 10 days before abatement begins unless emergency variance applies; includes site, contractor, dates, and ACM quantity.
- Asbestos handling license
- NYS license required for contractors performing asbestos abatement; individual workers and supervisors also need NYSDOL certificates for their roles.
- Asbestos handler certificate
- NYSDOL certificate for abatement workers; requires approved initial training and annual refresher; must be on site and available for inspection.
- Supervisor certificate
- Required for asbestos abatement supervisors in NY; training covers supervision, work practices, and regulations; annual refresher maintains certification.
- Industrial Code Rule 56
- 12 NYCRR 56, New York's asbestos regulation covering licensing, notification, work practices, air monitoring, and clearance for asbestos projects.
- Variance request
- Formal NYSDOL request to use an alternative method when strict Rule 56 compliance is impractical; requires application and may require public notice.
- NYC DEP asbestos filing
- New York City asbestos projects require a separate DEP notification or filing in addition to NYSDOL notification; local rules can be stricter than state.
- ACM definition
- Asbestos-containing material contains more than 1% asbestos by weight, determined by accredited laboratory analysis of representative bulk samples.
- Friable asbestos material
- Material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry; friability increases release and control requirements.
- Presumed ACM
- Suspect material assumed to contain asbestos until sampled and analyzed; includes thermal system insulation and sprayed-on or troweled surfacing.
- PLM bulk analysis
- Polarized light microscopy identifies asbestos type and estimates percentage; standard method for bulk samples; low-level or vermiculite may need point counting.
- Category I non-friable
- Non-friable asbestos material such as asphalt roofing, asphalt shingles, and vinyl floor tile; still regulated when disturbed or damaged.
- Asbestos fiber definition
- For PCM counting, a fiber has length greater than 5 micrometers, diameter less than 3 micrometers, and aspect ratio at least 3:1.
- Negative pressure enclosure
- Work area sealed with plastic and kept under negative pressure by HEPA exhaust units so air flows inward and fibers do not escape.
- Decontamination unit
- Sequence of clean room, shower, and equipment room that workers pass through to remove contamination before leaving the enclosure.
- Critical barrier
- Plastic sheeting sealing openings, HVAC vents, and penetrations to isolate the asbestos work area and prevent fiber migration.
- Wet methods
- Use water or amended water to keep asbestos material wet during removal, reducing airborne fiber release; dry sweeping and compressed air are prohibited.
- HEPA vacuum use
- Vacuum with high-efficiency particulate air filter for cleanup; never use ordinary shop vacuums because they exhaust asbestos fibers.
- Glove bag
- Sealed bag with sleeves and gloves used to remove small amounts of pipe insulation without building a full enclosure.
- Respirator minimum
- For most asbestos abatement, minimum half-face air-purifying respirator with HEPA filters; higher exposures need full-face or supplied-air with higher assigned protection.
- NIOSH 7400 method
- Phase contrast microscopy method for counting airborne fibers; samples collected on MCE filters and counted in specific fields.
- OSHA asbestos PEL
- Permissible exposure limit 0.1 fibers per cubic centimeter as 8-hour TWA; STEL 1.0 f/cc for 30 minutes; excursion limit 1.0 f/cc.
- Clearance air sampling
- Sampling after visual inspection shows no debris; area air samples must meet the project clearance level before reoccupancy.
- Asbestos waste packaging
- Wet asbestos waste sealed in leak-tight labeled containers, commonly double 6-mil bags; sharp debris placed in rigid containers.
- Waste shipment record
- Documentation identifying generator, transporter, waste quantity, and permitted disposal facility; retained to verify proper disposal.
- Pump calibration
- Air sampling pumps calibrated before and after each sampling event with a primary standard; flow rate recorded on the sample data sheet.
