ME Asbestos Abatement key terms

A group of naturally occurring fibrous silicate minerals that resist heat and chemicals and can split into microscopic fibers; inhalation of these fibers is linked to serious lung disease.

Asbestos-containing material that can be crumbled, pulverized, or reduced to powder by hand pressure when dry, and therefore readily releases fibers into the air.

Asbestos-containing material that cannot be crumbled or powdered by ordinary hand pressure, such as asbestos-cement siding or floor tile, and releases fibers mainly when cut, sanded, or broken.

A chronic, progressive scarring of lung tissue caused by inhaling asbestos fibers; it reduces lung elasticity and breathing capacity and typically appears years after sustained exposure.

A rare cancer of the thin membranes lining the chest, abdomen, or heart, strongly associated with asbestos exposure and usually developing decades after the exposure occurred.

The long delay, often twenty to forty years or more, between a person's initial asbestos exposure and the appearance of an associated disease such as mesothelioma or asbestosis.

Any material or product that contains more than one percent asbestos by weight, determined by laboratory analysis or assumed by regulation; such material triggers abatement and handling requirements.

Material that has not been sampled or analyzed but must be treated as asbestos-containing until testing proves otherwise, a default assumption used to protect workers and occupants.

A physical piece of material collected according to prescribed procedures and sent to an accredited laboratory to determine whether and how much asbestos it contains.

The collection and laboratory analysis of airborne samples to measure fiber concentration during and after abatement, used to verify worker protection and clearance of the work area.

Air monitoring performed in the breathing zone of an individual worker to estimate that person's exposure and to confirm that respiratory protection is adequate.

A device worn over the face to filter or supply clean air and prevent inhalation of asbestos fibers; selection, fit testing, and medical clearance are required before use.

Any activity that removes, encapsulates, encloses, repairs, or otherwise disturbs asbestos-containing material, including preparation, cleanup, and disposal of the resulting waste.

A treatment that coats asbestos-containing material with a sealant to bind fibers and prevent release, leaving the material in place rather than removing it.

A method of hazard control that builds an airtight barrier around asbestos-containing material so the material is isolated from occupied space instead of being removed.

A sealed work area, often built with plastic sheeting and maintained under negative pressure, that prevents asbestos fibers from escaping into surrounding spaces during abatement.

A condition in which air pressure inside the containment is kept lower than outside so air flows inward, preventing fibers from drifting out when openings occur.

A vacuum equipped with a high-efficiency particulate air filter capable of capturing very fine fibers; it is the required tool for cleaning asbestos debris rather than ordinary vacuums.

Working practices that keep asbestos material wet with water or amended water during removal and handling so fibers stay bound and are less likely to become airborne.

A staged enclosure, typically with clean, shower, and dirty rooms, that workers pass through to remove contaminated clothing and fibers before leaving the work area.

The post-abatement inspection and air sampling process confirming that the work area is clean and fiber levels meet the required threshold before containment is removed or space reoccupied.

A waste category covering friable asbestos material and certain non-friable material that has been damaged or will be crushed, subjecting it to stricter handling and disposal rules.

Non-friable asbestos-containing material such as packings, gaskets, and asphalt roofing products that generally remains non-friable and is regulated differently from more fragile material.

Non-friable asbestos-containing material, such as some siding and cement products, that is more likely to be crumbled or pulverized during handling and demolition.

A tracking document that follows asbestos waste from the generation site through transport to the disposal facility, with signed copies retained to prove proper disposal.

A shipping document required for hazardous or regulated waste that identifies the material, quantity, generator, transporter, and destination facility for tracking and accountability.

A person or business that moves asbestos waste between sites; transporters must meet licensing, packaging, labeling, and recordkeeping requirements for the material they carry.

A permitted site authorized to receive and bury asbestos waste in accordance with regulatory requirements, providing the final destination recorded on shipping papers.

A required advance written notice to the state agency describing an abatement project, its location, scope, schedule, and contractor, submitted before work begins.

A credential issued by the state allowing a business to perform asbestos abatement work; the firm must meet insurance, training, and compliance conditions to hold it.

A personal credential proving that an individual completed required asbestos training and is authorized to perform abatement work under a licensed contractor.

A credential for the person who directs abatement work on site, responsible for containment, work practices, worker protection, and compliance with regulations.

An individual capable of identifying asbestos hazards and with authority to take prompt corrective action, often assigned to oversee safety on smaller or routine projects.

An organization approved to deliver asbestos abatement courses whose curriculum and instruction meet state or federal requirements for certification and refresher training.

Periodic retraining that certified asbestos workers and supervisors must complete to renew their credentials and stay current on regulations and safe work practices.

A specific circumstance in which a regulatory requirement does not apply, such as certain small-scale or owner-occupied residential work, defined narrowly by the regulations.

The Maine regulation governing asbestos management, setting requirements for inspection, notification, abatement practices, licensing, training, and waste handling within the state.

The potential for asbestos fibers to be released and inhaled, created when material is disturbed, damaged, or deteriorated and becomes friable or airborne.
