Disinfection profile means a summary of Giardia lamblia inactivation through the treatment plant.
Negative pressure respirator (tight fitting) means a respirator in which the air pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.
Paint means any pigmented liquid, liquefiable, or mastic composition designed for application to a substrate in a thin layer which is converted to an opaque solid film after application and is used for protection, decoration or identification, or to serve some functional purpose such as the filling or concealing of surface irregularities or the modification of light and heat radiation characteristics.
Mist spray adhesive means any aerosol which is not a special purpose spray adhesive and which delivers a particle or mist spray, resulting in the formation of fine, discrete particles that yield a generally uniform and smooth application of adhesive to the substrate.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
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.
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.

Soft drinks means nonalcoholic beverages that contain natural or artificial sweeteners. "Soft drinks" does not include beverages that contain milk or milk products, soy, rice, or similar milk substitutes, or that contains greater than fifty per cent vegetable or fruit juice by volume.
HEPA filter means a high efficiency particulate absolute air filter capable of trapping and retaining 99.97 percent of fibers greater than 0.3 micrometers in mass median aerodynamic diameter equivalent.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Sludge dryer means any enclosed thermal treatment device that is used to dehydrate sludge and that has a maximum total thermal input, excluding the heating value of the sludge itself, of 2,500 Btu/lb of sludge treated on a wet-weight basis.
Infection means the entry and development or multiplication of an infectious agent in the body of humans and animals that may constitute a public health risk;
Healing arts screening means the testing of human beings using x-ray machines for the detection or evaluation of health indications when such tests are not specifically and individually ordered by a licensed practitioner of the healing arts legally authorized to prescribe such x-ray tests for the purpose of diagnosis or treatment.
COVID-19 symptoms means fever of 100.4 degrees Fahrenheit or higher, chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, or diarrhea, unless a licensed health care professional determines the person’s symptoms were caused by a known condition other than COVID-19.
