The state agency that administers asbestos abatement notification, licensing, and air quality enforcement in Kentucky under its asbestos program regulations.
- accreditation
- Related: competent person, asbestos abatement contractor license
Formal certification that a worker, supervisor, inspector, or project designer has completed required asbestos training and passed an examination for that discipline.
- asbestos abatement contractor license
- Related: accreditation, competent person
A state-issued authorization allowing a business entity to perform asbestos abatement work, contingent on accredited personnel and required insurance or bonding.
- OSHA permissible exposure limit
- Related: excursion limit, personal air sampling
The regulatory ceiling on airborne asbestos concentration in the workplace, set as an eight-hour time-weighted average of 0.1 fibers per cubic centimeter.
- excursion limit
- Related: OSHA permissible exposure limit, personal air sampling
A short-term asbestos exposure cap of 1.0 fiber per cubic centimeter averaged over thirty minutes, which must not be exceeded at any time during a shift.
- competent person
- Related: accreditation, negative pressure enclosure
An individual capable of identifying asbestos hazards and authorized to take prompt corrective action, responsible for worksite inspections and supervision of abatement activities.
- respirator fit test
- Related: half-face respirator, PAPR
A procedure confirming that a tight-fitting respirator seals against the wearer's face, performed qualitatively or quantitatively before initial use and at required intervals.
- half-face respirator
- Related: PAPR, respirator fit test
A tight-fitting air-purifying mask covering nose and mouth, fitted with particulate filters rated for asbestos, used for lower exposure tasks under a written program.
- PAPR
- Related: half-face respirator, HEPA filter
Powered air-purifying respirator that uses a blower to push filtered air into a loose or tight-fitting facepiece, reducing breathing resistance during abatement work.
- HEPA filter
- Related: negative air machine, PAPR
A high-efficiency particulate air filter rated to remove at least 99.97 percent of particles 0.3 micrometers in diameter, used in respirators, vacuums, and negative air units.
- negative pressure enclosure
- Related: negative air machine, critical barrier
A sealed work area kept at lower air pressure than surrounding spaces so air flows inward, preventing fiber escape; maintained by exhaust units with HEPA filtration.
- negative air machine
- Related: negative pressure enclosure, HEPA filter
A HEPA-filtered exhaust unit that draws air from a containment, creating pressure differential and air changes while discharging filtered air to the outside or adjacent space.
- critical barrier
- Related: negative pressure enclosure, decontamination unit
A physical partition such as plastic sheeting or rigid board that seals a containment boundary and must remain intact to prevent fiber migration.
- work practice controls
- Related: fiber release, amended water
Procedures that reduce fiber release at the source, including wet methods, careful removal sequencing, immediate bagging of debris, and prohibition of dry sweeping.
- amended water
- Related: work practice controls, fiber release
Water mixed with a wetting agent that lowers surface tension so asbestos fibers are wetted more thoroughly, suppressing dust during removal and cleanup.
- glove bag
- Related: mini-enclosure, work practice controls
A sealed plastic bag with built-in sleeves and gloves that encloses small fixtures or pipe sections so material can be removed without opening the containment.
- mini-enclosure
- Related: glove bag, negative pressure enclosure
A small, portable containment built around a localized work area, such as a pipe run, using plastic sheeting and negative air filtration for limited removals.
- decontamination unit
- Related: critical barrier, personal protective equipment
A three-stage sequence of clean room, shower, and equipment or dirty room that workers pass through to remove contamination before leaving the work area.
- personal protective equipment
- Related: decontamination unit, respirator fit test
Specialized clothing and gear such as disposable coveralls, respirators, gloves, and boot covers worn to prevent asbestos contact and carryout contamination.
- asbestos waste shipment record
- Related: NESHAP, waste packaging
A tracking document accompanying regulated asbestos waste from the generation site to the disposal facility, with signed receipts confirming delivery.
- waste packaging
- Related: asbestos waste shipment record, amended water
Placing removed asbestos debris in leak-tight, labeled containers, typically doubled bags or drums, while still wet and before transport.
- air monitoring
- Related: phase contrast microscopy, personal air sampling
Collecting airborne samples on filters and analyzing them to estimate fiber concentrations for exposure assessment, containment verification, or clearance.
- personal air sampling
- Related: OSHA permissible exposure limit, air monitoring
Drawing air through a filter worn in the worker's breathing zone to measure individual exposure against permissible exposure limits.
- phase contrast microscopy

The standard optical method for counting fibers on air sample filters, used for most occupational and clearance sampling but unable to distinguish asbestos from other fibers.
- clearance sampling
- Related: air monitoring, negative pressure enclosure
Post-abatement air sampling and visual inspection confirming that fiber levels are below the required threshold before a containment is removed or reoccupied.
- bulk sample
- Related: asbestos-containing material, presumed asbestos-containing material
A small physical specimen of suspect building material collected with proper technique and analyzed by an accredited laboratory to determine asbestos content.
- presumed asbestos-containing material
- Related: bulk sample, asbestos-containing material
Suspect building material that has not been sampled or analyzed and must be treated as containing asbestos until proven otherwise.
