32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- ACM definition
- Any material containing more than 1% asbestos by weight, as determined by polarized light microscopy or other approved method.
- RACM definition
- Regulated asbestos-containing material: friable ACM, or nonfriable ACM that will be or has been crumbled, pulverized, or reduced to powder.
- Friability
- The ability of a material to be crumbled, pulverized, or reduced to powder by hand pressure when dry.
- Chrysotile
- A serpentine asbestos mineral with curly, flexible fibers; it is the most commonly used asbestos type in commercial products.
- Amphibole asbestos
- A group of straight, needle-like asbestos fibers including amosite, crocidolite, anthophyllite, tremolite, and actinolite; more chemically resistant than chrysotile.
- Asbestosis
- A nonmalignant fibrotic lung disease caused by cumulative asbestos exposure, typically appearing 10–20 years after exposure.
- Mesothelioma
- A cancer of the mesothelial lining of the chest or abdomen associated with asbestos exposure, often with a 20–50 year latency.
- OSHA PEL
- The permissible exposure limit for asbestos is 0.1 fiber per cubic centimeter as an 8-hour time-weighted average.
- Excursion limit
- The OSHA limit of 1.0 fiber per cubic centimeter over a 30-minute sampling period for asbestos exposure.
- Smoking synergy
- Smoking and asbestos exposure together greatly increase lung cancer risk beyond the sum of their individual effects.
- IDEM asbestos program
- Indiana Department of Environmental Management administers the federal NESHAP asbestos program under 326 IAC 14-10.
- NESHAP notification exemption
- Single-family residential buildings with four or fewer dwelling units are exempt from NESHAP notification requirements.
- Renovation threshold
- Renovation is exempt from NESHAP notification if RACM removed is less than 260 linear feet, 160 square feet, or 35 cubic feet.
- Facility definition
- Any institutional, commercial, public, industrial, or residential structure, installation, or building, including mobile homes and ships.
- AHERA
- Asbestos Hazard Emergency Response Act; requires inspections, management plans, and response actions in schools under 40 CFR Part 763.
- NESHAP citation
- The federal asbestos NESHAP is codified at 40 CFR Part 61, Subpart M.
- OSHA construction standard
- 29 CFR 1926.1101 sets asbestos exposure limits, monitoring, PPE, and training requirements for construction work.
- ASHARA
- Asbestos School Hazard Abatement Reauthorization Act; extended AHERA training requirements to public and commercial building inspectors and abatement workers.
- Homogeneous area
- A material that is uniform in color, texture, and date of application; each homogeneous area must be sampled during an inspection.
- PLM analysis
- Polarized light microscopy is the standard method for analyzing bulk asbestos samples and can detect asbestos at 1% by weight.
- Inspection report
- A written document prepared by the inspector that includes sample locations, laboratory results, quantities, and recommendations.
- AHERA reinspection
- School inspections must be repeated every 3 years by an accredited inspector under 40 CFR 763.85.
- 10 working days
- The minimum advance notice required before starting demolition or renovation involving RACM, unless an emergency waiver is granted.
- Notification content
- The IDEM notification must include facility name, address, owner, contractor, start and completion dates, and estimated RACM quantities.
- Demolition notification
- Notification is required for demolitions even if no asbestos is present, unless the facility is exempt (e.g., small residential).
- Amended water
- Water containing a surfactant used to wet asbestos materials and reduce fiber release during abatement.
- Negative air pressure
- A containment technique using HEPA-filtered exhaust to keep the work area under negative pressure and prevent fiber migration.
- Critical barriers
- Plastic sheeting used to seal all openings, windows, doors, and HVAC systems in the work area during abatement.
- Clearance air monitoring
- Air sampling conducted after abatement to ensure fiber levels are below clearance criteria before the containment is dismantled.
- Asbestos waste labeling
- Containers must be labeled 'DANGER: CONTAINS ASBESTOS FIBERS' and 'AVOID CREATING DUST' and include generator information.
- Permitted landfill
- Asbestos waste must be disposed of at a landfill authorized to accept asbestos-containing waste and covered daily.
- Annual refresher
- Asbestos workers and supervisors must complete annual refresher training to maintain certification.
