Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one 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.
Low-solids coating means a coating containing 0.12 kilogram or less of solids per liter (one pound or less of solids per gallon) of coating material.
Encapsulant means a substance that forms a barrier between lead-based paint and the environment using a liquid-applied coating (with or without reinforcement materials) or an adhesively bonded covering material.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Cleaner means an employee engaged in cutting or trimming off loose ends of cotton or cloth left on garments or parts of garments by previous operators;
Incineration means an engineered process involving burning or combustion of solid waste to thermally degrade waste materials at high temperatures;
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.
Bathing means washing oneself by sponge bath; or in either a tub or shower, including the task of getting into or out of the tub or shower.
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).
Encapsulation means the application of an encapsulant.
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;
Self-contained breathing apparatus or "SCBA" means an atmosphere-supplying respirator for which the breathing air source is designed to be carried by the user.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Glass cleaner means a cleaning product designed primarily for cleaning surfaces made of glass. Glass cleaner does not include products designed solely for the purpose of cleaning optical materials used in eyeglasses, photographic equipment, scientific equipment and photocopying machines.
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.
Massive Multiauthor Collaboration Site (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.
Roll coating means the application of a coating material to a substrate by means of hard rubber or steel rolls.
Fabrication means making up data or results and recording or reporting them.
Fireworks means display fireworks, pyrotechnic special effects fireworks and consumer fireworks;
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.
Filtration means a process for removing particulate matter from water by passage through porous media.
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.
Gasohol means a blended fuel composed of gasoline and fuel grade ethanol.
Cyanoacrylate adhesive means any adhesive with a cyanoacrylate content of at least 95% by weight.
Defoliant means any substance or mixture of substances intended for causing the leaves or foliage to drop from a plant, with or without causing abscission.
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
