Glossary

General terms

Asynchronous instruction (ASTD)

A general term used to describe forms of education, instruction and learning that do not occur in the same place or at the same time. It uses resources that facilitate information sharing outside the constraints of time and place among a network of people.

Blended learning
Describes the practice of using several training delivery mediums in a single training program and typically refers to the combination of classroom instruction and eLearning.

Distance learning

An educational situation in which the instructor and students are separated by time, location or both. Education or training courses are delivered to remote locations via synchronous or ASTD.

eLearning (electronic learning)

A term covering a wide set of applications and processes that includes web-based learning, computer-based learning, virtual classrooms and digital collaboration.

Face-to-face Training

Usually refers to traditional classroom training in which an instructor teaches a course to a room of training participants. The term is used synonymously with on-site training, classroom training and instructor-led training (slightly modified from ASTD definition).

Module

A unit of instruction that can be measured, evaluated for change, assembled to form complete courses or bypassed as a whole, and that is usually intended to teach one or a group of skills or areas of knowledge (slightly modified from ASTD definition).

Evaluator

A person who evaluates learners.

Instructor

A person who delivers training programs.

Qualification

A skill, quality or attribute that makes somebody suitable for a job, activity or task.

Asbestos abatement terms

Abatement

Procedures to encapsulate, enclose or remove asbestos-containing material.

ACM (Asbestos-containing material)

• A friable material containing 0.1 per cent or greater asbestos
• A non-friable material containing 1.0 per cent or greater asbestos
• Vermiculite insulation that contains asbestos

Air monitoring

The process of measuring a sample of airborne fibre levels in a specified area over a period of time. This involves drawing a known volume of air through a filtered cassette with an effective (0.25 um) pore size, counting the fibres that collect on the filter and expressing the result as fibres per cubic centimetre (f/cc).

Asbestos

A generic name given to a number of commercially significant naturally occurring hydrated mineral silicates. These silicates are incombustible, separate into sub-light microscopic fibres and have a unique crystalline structure. Asbestos may be found as the fibrous form of crocidolite, amosite, chrysotile, anthophyllite, actinolite, tremolite or a mixture containing any of these minerals

Contaminated item

Any object that has been exposed to airborne asbestos fibres without being sealed off, isolated or cleaned.

Decontamination facility

An area constructed to prevent the spread of asbestos fibres beyond the work area. It

is a series of rooms consisting of a clean room, a shower room, and an equipment or waste transfer room. There can be 2 sets of decontamination facilities, one for personnel leaving the work area and one for waste being removed from the work area.

Decontamination unit

A series of interconnected airlocks used for employee or waste decontamination.

Encapsulation

The process of coating asbestos-containing materials to control the release of asbestos fibres into the ambient air. A sealant is applied that hardens the material (penetrant sealant) and/or provides a protective layer.

Fibre

A particle that is at least five microns long and has a length-to-width ratio equal to or greater than 3:1.

GFCI (ground fault circuit interrupter) breaker

An electrical safety device that quickly breaks an electrical circuit with leakage current to ground to protect workers against electric shock from electrical equipment.

Glove bag

A one-time use, manufactured impervious bag-like enclosure constructed of at least 6-mil transparent polyethylene sheeting, seamless at the bottom, with inward projecting long sleeve glove(s), which may also contain an inward-projecting water-wand sleeve, an internal tool pouch, and an attached, labelled receptacle or portion for asbestos waste. The glove bag is constructed and installed to surround the object or area to be decontaminated and contain all asbestos fibres released during the abatement process.

Grab bulk sample

Rudimentary collection of suspected ACM debris from horizontal or vertical surfaces without the use of hand tools.

HEPA Filter

A high-efficiency particulate arresting (HEPA) filter. HEPA filters are used in both respirators and air handling equipment. The filters have a minimum particulate removal efficiency of 99.97 per cent for thermally generated mono-dispersed DOP aerosol particles with a diameter of 0.3 micrometres and a maximum pressure drop of 1.0 inch water gauge when clean and operating at their rated airflow capacity.

Manometer

A device that measures the pressure of a medium (a liquid or a gas). The manometer used to measure the pressure differential for the enclosure should be properly calibrated in accordance with the manufacturer’s specifications and should be in good working order to offer a reliable measurement of the pressure differential.

Negative air pressure system

Reduced air pressure within the work area compared to air pressure in adjacent

areas, produced through the use of negative air units. Reduced pressure in the work area prevents leakage of contaminated air out of the work area. Airborne fibres will tend to be pulled into the HEPA filter-equipped filtration system instead of escaping the work area (enclosure).

Removal

Procedures necessary to strip asbestos-containing materials from designated areas and to then dispose of these materials at an acceptable site.

Respirator

Personal protective equipment that protects a worker against the inhalation of airborne contaminants, provided it is the correct type of respirator and is fitted, used, and maintained in accordance with the CSA Z94.4-11 or the most current revision.
