Polystyrene foam means blown polystyrene and expanded and
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Expanded polystyrene means blown polystyrene and expanded
Corrosion inhibitor means a substance capable of reducing the corrosivity of water toward metal plumbing materials, especially lead and copper, by forming a protective film on the interior surface of those materials.
Cyanoacrylate adhesive means any adhesive with a cyanoacrylate content of at least 95% by weight.
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
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
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.
Air-purifying respirator means a respirator with an air-purifying filter, cartridge, or canister that removes specific air contaminants by passing ambient air through the air-purifying element.
Perfluoroalkyl and polyfluoroalkyl substances or “PFAS” means a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom.
Cannabinoid extract means a substance obtained by separating cannabinoids from marijuana by:
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.
Chemicals means substances applied to forest lands or timber including pesticides, fertilizers, and other forest chemicals.
Flexible vinyl adhesive means an aerosol adhesive designed to bond flexible vinyl to substrates. Flexible vinyl means a nonrigid polyvinyl chloride plastic with at least five percent, by weight, of plasticizer content. A plasticizer is a material, such as a high boiling point organic solvent, that is incorporated into a vinyl to increase its flexibility, workability, or distensibility, and may be determined using ASTM Method E260-91 or from product formulation data.
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);
Aerosol coating product means a pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application, or for use in specialized equipment for ground traffic/marking applications.
Cannabinoid means any of the chemical compounds that are the active constituents of marijuana.
thalassemia means a group of inherited disorders characterised by reduced or absent amounts of haemoglobin.
Diesel means a distillate oil which can be used as fuel for the operation of a compression ignition engine and which has an approximate boiling temperature of between 150 °C to 400 °C;
Chemical agent shall mean any compound which, when suitably disseminated, produces incapacitating, damaging or lethal effects on people, animals, plants or material property.
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.
Putrescible waste means a solid waste that contains organic matter capable of being decomposed by microorganisms so as to cause a malodor, gases, or other offensive conditions, or which is capable of providing food for birds and other vectors. Putrescible wastes may form a contaminated leachate from microbiological degradation, chemical processes, and physical processes. Putrescible waste includes, but is not limited to, garbage, offal, dead animals, general household waste, and commercial waste. All solid wastes which do not meet the definitions of inert or chemical wastes shall be considered putrescible wastes.
Disposable respirator means a respirator for which maintenance is not intended and that is designed to be discarded after excessive breathing resistance, sorbent exhaustion, physical damage, or end-of-service-life renders it unsuitable for use. Examples of this type of respirator are a disposable half-mask respirator or a disposable escape-only self-contained breathing apparatus (SCBA).
Biodegradable means degradable through a process by which fungi or bacteria secrete enzymes to convert a complex molecular structure to simple gasses and organic compounds.
