32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Asbestosis
- A chronic lung disease caused by inhalation of asbestos fibers, characterized by diffuse interstitial fibrosis; latency is typically 10–20 years after exposure.
- Mesothelioma
- A rare cancer of the pleura or peritoneum associated with asbestos exposure; latency is 20–50 years, and risk may occur at low exposure levels.
- OSHA PEL
- The permissible exposure limit for asbestos is 0.1 fibers per cubic centimeter (f/cc) as an 8-hour time-weighted average, with a 1.0 f/cc excursion limit over 30 minutes.
- NESHAP
- National Emission Standards for Hazardous Air Pollutants; 40 CFR 61 Subpart M regulates asbestos during demolition and renovation, requiring notification and work practices.
- AHERA
- Asbestos Hazard Emergency Response Act; 40 CFR 763 Subpart E requires accredited inspectors, management plans, and periodic surveillance for schools.
- OSHA Class I work
- Asbestos work involving removal of thermal system insulation or surfacing ACM/PACM; requires negative-pressure enclosure and regulated area.
- RACM
- Regulated Asbestos-Containing Material under NESHAP; includes friable ACM and nonfriable ACM that will be crumbled, pulverized, or reduced to powder during handling.
- Friable ACM
- Asbestos-containing material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry; more likely to release fibers.
- PACM
- Presumed Asbestos-Containing Material; surfacing material or thermal system insulation assumed to contain asbestos unless sampled and shown to be <1%.
- Homogeneous area
- A material of uniform color and texture throughout a building; samples from one homogeneous area are assumed to represent the entire area.
- AHERA sampling rule
- For each homogeneous area, collect at least 3 samples; if all positive, area is ACM; if all negative, non-ACM; if mixed, collect additional samples up to 7.
- Category I nonfriable
- Nonfriable asbestos-containing material such as asphalt roofing, gaskets, and resilient floor coverings; may become friable during demolition or renovation.
- Pre-inspection records review
- Review building drawings, prior reports, permits, and renovation history to identify likely asbestos-containing materials and plan the inspection.
- Sampling plan
- A written strategy detailing the number and locations of bulk samples per homogeneous area, based on regulatory requirements (e.g., AHERA 3 samples).
- Wet sampling methods
- Techniques using water or a wetting agent to suppress fiber release during bulk sampling; required to minimize exposure.
- Chain of custody
- A documented record tracking each sample from collection through laboratory analysis, including dates, times, and signatures of persons handling the sample.
- Composite sampling
- Combining multiple samples into one; generally not recommended for asbestos because it can dilute fiber content and cause false negative results.
- PLM
- Polarized Light Microscopy; the standard method for bulk asbestos analysis (NIOSH 9002, EPA 600/R-93/116), with a detection limit of about 1% by weight.
- TEM
- Transmission Electron Microscopy; used for air clearance samples under AHERA and can identify fibers smaller than 0.25 µm.
- PCM
- Phase Contrast Microscopy; used for OSHA air monitoring, counts fibers >5 µm but cannot distinguish asbestos from other fibers.
- PLM detection limit
- PLM can reliably detect asbestos at approximately 1% by weight; below this level, quantification is uncertain and may require other methods.
- Thermal system insulation
- Insulation on pipes, boilers, and ducts; a common asbestos-containing material, often friable and requiring special handling.
- HVAC plenum
- A compartment or chamber used for air distribution; may contain surfacing ACM that can release fibers into the air stream if damaged.
- Material condition assessment
- Evaluation of ACM as good, damaged, or significantly damaged; considers friability, accessibility, and potential for disturbance.
- AHERA management plan
- A document required for schools, including inspection results, response actions, and a plan for periodic surveillance and re-inspection.
- OSHA record retention
- Exposure records must be kept for 30 years; medical records for duration of employment plus 30 years.
- Inspection report contents
- Must include building description, inspection date, inspector accreditation, sampling locations, lab results, conclusions, and recommendations.
- Conflict of interest
- A situation where an inspector has a financial or personal interest in the outcome; must be avoided or disclosed to maintain objectivity.
- QA/QC procedures
- Quality assurance and quality control measures, such as using accredited labs, duplicate samples, and blank samples, to ensure data reliability.
- Abatement oversight
- Monitoring of abatement contractor activities to verify compliance with regulations, work practices, and project specifications.
- AHERA clearance
- Post-abatement air sampling analyzed by PCM; clearance requires fiber concentration <0.01 f/cc (or TEM <70 s/cc) after visual inspection.
- Aggressive sampling
- Air sampling conducted after disturbing air (e.g., with fans) to simulate normal building activity; used for AHERA clearance.
