OH Asbestos Abatement key terms

Any material or product that contains more than one percent asbestos by weight, as determined by polarized light microscopy. Ohio abatement rules apply to handling and removal of these materials in regulated facilities.

ACM that is friable, or that becomes friable when handled, or that is non-friable but will be disturbed by a regulated demolition or renovation. RACM triggers the strictest work practice and notification requirements.

Describes material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry. Friability drives risk because fibers release easily into air and are more readily inhaled.

Describes asbestos material that cannot be crumbled or powdered by ordinary hand pressure when dry. It still poses risk if cut, sanded, ground, or broken during renovation.

Non-friable asbestos material such as packings, gaskets, resilient floor coverings, and asphalt roofing products. It becomes regulated when sanded, ground, cut, or abraded so that it may release fibers.

Non-friable asbestos material other than Category I, such as asbestos cement siding, corrugated sheet, and some transite products. It becomes RACM if it is crumbled, pulverized, or reduced to powder during demolition or renovation.

Material assumed to contain asbestos until sampling and analysis prove otherwise. Treating suspect material as PACM is the default safe assumption during inspection and renovation planning.

Any building material that may contain asbestos because of its type, use, or age, including thermal system insulation, floor tile, mastic, and joint compound. Suspect materials must be assumed or tested before disturbance.

A physical portion of material collected for laboratory analysis to determine asbestos content. Proper sampling uses wet methods, minimizes fiber release, and follows a documented chain-of-custody.

The primary laboratory method for identifying asbestos in bulk building materials. It uses refractive index and optical properties to identify fiber type and estimate percentage by area.

A laboratory method used to count airborne fibers on membrane filters. It counts all fibers of respirable size and cannot distinguish asbestos from other fibers, so it is used for exposure monitoring.

A high-resolution method that identifies asbestos fibers by structure, chemistry, and crystal pattern. It is used for clearance air testing and for distinguishing asbestos from non-asbestos fibers.

A documented on-site survey to locate and assess suspect asbestos materials before renovation or demolition. It identifies material type, condition, quantity, and accessibility to support abatement planning.

A written record of inspection findings, including sample locations, laboratory results, material quantities, and condition. It guides the abatement scope and supports required regulatory notifications.

Any activity that removes, encapsulates, or encloses asbestos material, including related preparation, cleanup, and disposal. Proper abatement protects occupants and workers from fiber release.

Applying a sealant to asbestos material so fibers are bound and cannot become airborne. It does not remove the material, so the hazard remains and must be managed and documented.

Building an airtight barrier around asbestos material to isolate it from occupied space. The material stays in place, so future work in the area requires caution and updated records.

Written notice to the Ohio Department of Health before starting certain abatement projects, giving dates, location, contractor, and scope. Timely filing lets regulators schedule inspections and verify compliance.

The state program that licenses asbestos abatement contractors and certifies workers, supervisors, inspectors, and project designers. It enforces work practice standards, notification rules, and training requirements.

A business licensed by the state to perform asbestos abatement work. It must employ certified personnel, follow work practice standards, and maintain required records and insurance.

A certified individual who directs abatement work, enforces work practices, and ensures containment integrity. The supervisor oversees worker safety, air monitoring, and final cleanup.

A certified individual who performs hands-on removal, cleanup, and disposal of asbestos material under supervision. Certification requires approved training and periodic refresher courses.

State-issued credential confirming a person completed approved asbestos training and passed required exams. It must be renewed through refresher training and kept available on the job site.

Periodic retraining that certified asbestos personnel must complete to keep credentials current. It updates workers on regulation changes, work practices, and safety procedures.

A person capable of identifying asbestos hazards and authorized to take corrective action. This role inspects work areas, monitors conditions, and ensures required safeguards are in place.

Required procedures for abating asbestos safely, including wet methods, containment, negative pressure, and proper waste handling. They reduce fiber release and protect workers and building occupants.

A sealed work area kept at lower air pressure than surrounding spaces so air flows inward. This prevents asbestos fibers from escaping into occupied areas during abatement.

Plastic sheeting and sealed framing that separate the work area from occupied space. Barriers must be sturdy, sealed at seams, and inspected for damage throughout the project.

A connected series of chambers where workers remove contaminated clothing and clean themselves before leaving the work area. It typically includes a dirty room, shower, and clean room.

A vacuum equipped with a high-efficiency particulate air filter that traps very small particles, including asbestos fibers. It is used for cleanup and must be maintained and checked regularly.

Techniques that keep asbestos material wet during removal and handling to suppress dust and fiber release. Water or amended water is applied before and during disturbance.

A wetting agent added to water so it penetrates asbestos material more effectively and reduces airborne fibers. It is commonly called amended water in abatement work.

Gear worn to limit exposure, including respirators, disposable coveralls, gloves, and eye protection. Selection depends on exposure level and must be used with proper training and fit testing.

A test confirming a tight seal between a respirator and the wearer's face. It must be repeated periodically and whenever facial conditions or equipment change.

Collecting air samples to measure worker exposure to airborne asbestos fibers. Results guide respirator selection, work practice changes, and compliance with exposure limits.

An air sample collected in the worker's breathing zone using a pump and filter cassette. It estimates the individual's actual inhalation exposure during a task or shift.

The maximum allowable airborne asbestos concentration for a worker over an eight-hour shift. Employers must keep exposures at or below this level through controls and protective equipment.

Post-abatement air sampling to confirm the work area is clean before containment is removed or space is reoccupied. It verifies that fiber levels meet required clearance criteria.

A careful look at the work area for dust, debris, and residue after cleaning and before clearance testing. Any visible material must be removed and the area recleaned.

Packaging, labeling, transporting, and landfilling asbestos waste according to regulatory requirements. Waste must be wetted, sealed in leak-tight containers, and handled by trained personnel.

A documented record tracking a sample from collection through laboratory analysis. It preserves sample integrity and supports reliable, defensible results.
