(4) "Construction" or "construction project" means any activity subject to state or local building codes.
(5) "Construction documents" means written, graphic, and pictorial documents prepared or assembled for describing the design, location, and physical characteristics of the elements of a project necessary for obtaining a building permit.
(6) "Contaminant" means any hazardous material that occurs at greater than natural background levels.
(7) "Decibel (dB)" means a standard unit of measurement of sound pressure.
(8) "Decibel, A-weighted (dBA)" means a decibel measure that has been weighted in accordance with the A-weighting scale. The A-weighting adjusts sound level as a function of frequency to correspond approximately to the sensitivity of human hearing.
(9) "Department" means the Washington state department of health.
(10) "Drinking fountain" means the type of plumbing fixture that delivers a stream of water for drinking without actively cooling the water.
(11) "Emergency eye wash" means a hands-free device that:
(a) Irrigates and flushes both eyes simultaneously with tepid potable water;
(b) Activates an on-off valve in one second or less and remains on without user assistance until intentionally turned off; and
(c) Delivers at least 0.4 gallons (1.5 liters) of water per minute for at least fifteen minutes.
(12) "Emergency shower" means a hand-activated shower that delivers tepid potable water to cascade over the user's entire body at a minimum rate of 20 gallons (75 liters) per minute for at least fifteen minutes.
(13) "Equivalent sound level (Leq)" means the level of a constant sound that, over a given time period, contains the same amount of sound energy as the measured fluctuating sound.
(14) "Faucet" means a type of plumbing fixture that is a valved outlet device attached to a pipe that normally serves a sink or tub and can discharge hot water, cold water, or both.
(15) "First draw sample" means a water sample collected immediately upon opening a plumbing fixture that has not been used for at least eight hours prior to collection.
(16) "Flush sample" means a water sample collected after allowing cold water to run for at least thirty seconds from a plumbing fixture that has not been used for at least eight hours prior to collection.
(17) "Foot-candle" means a unit of measure of the intensity of light falling on a surface, equal to one lumen per square foot.
(18) "Hazardous materials" means toxic, corrosive, flammable, explosive, persistent, or chemically reactive substances that, depending on dose and circumstances, pose a threat to human health.
(19) "Imminent health hazard" means a significant threat or significant danger to health or safety that requires immediate action to prevent serious illness, injury, or death.
(20) "Implementation" or "implemented" means being given or having the force of law, requiring compliance, and being subject to enforcement.
(21) "Laboratory" means instructional areas of the school facility where students might be exposed to greater potential health and safety hazards than typically exist in general academic classrooms.

(24) "Mechanical exhaust ventilation" means the removal of indoor air to the outside of the building by mechanical means.
(25) "Noise criterion (NC)" means a system for rating the noise level in an occupied area by comparing actual or calculated sound level spectra with a series of established octave band spectra.
(26) "Noise criterion 35 (NC35)" means the curve for specifying the maximum permissible sound pressure level for each frequency band.
(27) "Preschool" means an instructional curriculum and portion of a school facility designed to instruct children not old enough to attend kindergarten.
(28) "Portable" means any relocatable structure that is transported to a school site and is placed or assembled there for use by students as part of a school facility.
