Smoke means the gases, particles, or vapors released into the air as a result of combustion, electrical ignition or vaporization, when the apparent or usual purpose of the combustion, electrical ignition or vaporization is human inhalation of the byproducts, except when the combusting or vaporizing of materials contains no tobacco or nicotine and the purpose of the inhalation is solely olfactory, such as, for example, smoke from incense. The term "smoke" includes, but is not limited to, tobacco smoke, electronic cigarette vapors, and cannabis smoke.
NACE means National Association of Corrosion Engineers
Dust means any solid matter in a fine or disintegrated form which is capable of being dispersed or suspended in the atmosphere;
Noise means two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant frequency which is a multiple of 1,0 Hz during a period of 30 seconds.
Smoke detector means a device which detects particles or products of combustion other than heat.
Fire fighter means any person employed by the state or any political subdivision as a member or officer of a fire depart- ment or a member of a volunteer department, including the state fire marshal and deputies.
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Erosion means the detachment and movement of soil or rock fragments by water, wind, ice, or gravity.
Drum means any cylindrical metal shipping container of 13 to 110 gallon capacity.
Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Odor means that property of an air contaminant that affects the sense of smell.
Shutter means a device attached to the tube housing assembly which can intercept the entire cross sectional area of the useful beam and which has a lead equivalency not less than that of the tube housing assembly.
Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Slash means all debris created on the Work area by the precommercial thinning operation.
Seepage pit means an excavation deeper than it is wide that receives septic tank effluent and from which the effluent seeps from a structural internal void into the surrounding soil through the bottom and openings in the side of the pit.
Engine degreaser means a cleaning product designed to remove grease, grime, oil and other contaminants from the external surfaces of engines and other mechanical parts.
Overflow means the intentional or unintentional diversion of flow from the collection and transport systems, including pumping facilities.
Pile means any non-containerized accumulation of solid, nonflowing hazardous waste that is used for treatment or storage and that is not a containment building.

Inclement Weather means any weather condition that delays the scheduled arrival or departure of a Common Carrier.
Hacking means unauthorised access to any computer or other equipment or component or system or item which processes, stores, transmits or retrieves data.
Filtration means a process for removing particulate matter from water by passage through porous media.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
