Polymer means a substance consisting of molecules characterised by the sequence of one or more types of monomer units and comprising a simple weight majority of molecules containing at least three monomer units which are covalently bound to at least one other monomer unit or other reactant and consists of less than a simple weight majority of molecules of the same molecular weight. Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. In the context of this definition a ‘monomer unit’ means the reacted form of a monomer in a polymer;
Polyolefin Adhesive means an aerosol adhesive designed to bond polyolefins to substrates.
Perfluoroalkyl and polyfluoroalkyl substances or “PFAS” means a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom.
Brachytherapy source means a radioactive source or a manufacturer-assembled source train or a combination of these sources that is designed to deliver a therapeutic dose within a distance of a few centimeters.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (μg/m3);
Brachytherapy means a method of radiation therapy in which sealed sources are utilized to deliver a radiation dose at a distance of up to a few centimeters, by surface, intracavitary, or interstitial application.
Halogen means one of the chemical elements chlorine, bromine or iodine.
Chemical agent shall mean any compound which, when suitably disseminated, produces incapacitating, damaging or lethal effects on people, animals, plants or material property.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Cannabinoid edible means food or potable liquid into which a cannabinoid concentrate, cannabinoid extract or dried marijuana leaves or flowers have been incorporated.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Hydrofluorocarbons means compounds that only contain hydrogen, fluorine, and carbon.
Radionuclide means a radioactive element or a radioactive isotope.
Chemicals means substances applied to forest lands or timber including pesticides, fertilizers, and other forest chemicals.
Anaerobic digester means a liquid manure storage area that is constructed with the intent to capture and combust gas emissions resulting from the digestion of waste by microbes in anaerobic conditions. An anaerobic digester is a LMSA and is required to comply with all requirements applicable to LMSAs. Requirements specific to anaerobic digesters will be noted when applicable.
Epinephrine auto-injector means a device for immediate self-administration or administration by another trained person of a measured dose of epinephrine to a person at risk of anaphylaxis.
Radiopharmaceutical means any drug that exhibits spontaneous disintegration of unstable nuclei with the emission of nuclear particles or photons and includes any non-radioactive reagent kit or radionuclide generator that is intended to be used in the preparation of any such substance, but does not include drugs such as carbon-containing compounds or potassium-containing salts that include trace quantities of naturally occurring radionuclides. The term also includes any biological product that is labeled with a radionuclide or intended solely to be labeled with a radionuclide.
Pyrolysis means the thermal degradation of a substance in the absence of any oxidising agent, which does not form part of the substance itself, to produce char and gas and/or liquid; and
Cannabinoid means any of the chemical compounds that are the active constituents of marijuana.
Biological agent shall mean any pathogenic (disease producing) micro-organism(s) and/or biologically produced toxin(s) (including genetically modified organisms and chemically synthesized toxins) which cause illness and/or death in humans, animals or plants.
Polystyrene foam means blown polystyrene and expanded and
explosive actuated fastening device means a tool that is activated by an explosive charge and that is used for driving bolts, nails and similar objects for the purpose of providing fixing;
Cannabidiol means a finished preparation containing, of its total cannabinoid content, at least 98 percent cannabidiol and not more than 0.90 percent tetrahydrocannabinol by volume that has been extracted from marijuana or synthesized in a laboratory.
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Biomethane means biogas that meets pipeline quality natural gas standards.
Web spray adhesive means any aerosol adhesive that is not a mist spray or special purpose spray adhesive.
